Description:
RELATED APPLICATIONS 
     This application claims priority to, and is a continuation-in-part application of, U.S. patent application Ser. No. 14/065,100, titled “Dual Recyclables and Non-Recyclable Waste Collection Device and Method Therefor,” filed Oct. 28, 2013, which is a divisional application of U.S. patent application Ser. No. 12/419,968, titled “Dual Recyclables and Non-Recyclable Waste Collection Device and Method Therefor,” filed Apr. 7, 2009, now U.S. Pat. No. 8,646,644, the disclosures of which are hereby incorporated by this reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to waste collection; and more specifically, to a dumpster-like device that integrates a container for non-recyclable waste and a container for recyclables within the same space provided by current single-dumpster areas and enclosures; and, provides a method for the separate collection of the contents of each of the two containers using existing industry-standard waste removal vehicles and facilities. 
     BACKGROUND 
     Recycling programs are beneficial for many reasons. For example: 1) Many American companies rely on recycling programs to provide the raw materials they need to make new products. Recycling in the U.S. is a $236 billion a year industry. 2) More than 56,000 recycling and reuse enterprises employ 1.1 million workers nationwide. 3) The average American business discards one hundred pounds of garbage every day. Most of this garbage goes into landfills, where it is compacted and buried. 4) Recycling can provide advantages over placing materials into landfills, such as requiring less energy, using fewer natural resources, and keeping waste from accumulating in landfills. 5) Recycling can offer energy savings over manufacturing with new or virgin materials. For example, manufacturing with recycled aluminum cans uses 95% less energy. 6) Recycling can preserve existing landfill space. 7) In the year 2000, recycling of solid waste prevented the release of an estimated 32.9 million metric tons of carbon equivalent (MMTCE, the unit of measure for greenhouse gases) into the air. 8) Making goods from recycled materials generates less water pollution than manufacturing from virgin materials. 9) Using recycled materials reduces the need to damage forests, wetlands, rivers, and other places essential to wildlife. 10) Recycling and buying recycled products creates demand for more recycled products, decreasing waste and helping our economy. 
     Notwithstanding the benefits of recycling, large quantities of recyclable materials are estimated to be deposited in landfills every year.

It is to be appreciated that a myriad of additional or alternate examples of varying scope could have been presented, but have been omitted for purposes of brevity. 
     While this disclosure includes a number of embodiments in different forms, there is presented in the drawings and written descriptions in the following pages detail of particular embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosed structures, devices, methods, and systems, and is not intended to limit the broad aspect of the disclosed concepts to the embodiments illustrated. Additionally, it should be understood by those of ordinary skill in the art that other manufacturing devices and examples could be intermixed or substituted with those provided. In places where the description refers to particular embodiments, it should be readily apparent that a number of modifications can be made without departing from the spirit thereof and that these embodiments and implementations may be applied to other technologies as well. Accordingly, the disclosed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the disclosure and the knowledge of one of ordinary skill in the art. 
     As indicated above, notwithstanding the benefits of recycling, large quantities of recyclable materials are estimated to be deposited in landfills every year. Therefore, a need exists to decrease an amount of recyclable materials that are not recycled, and to increase an amount of material that is recycled. Less than optimal levels of recycling can be attributed to a number of factors. In some instances, current infrastructure for commercial bulk waste collection, such as space constraints, can force a choice between collection of recyclable and collection of non-recyclable materials. For example, many waste collection vehicles, such as standard fork lift-operated waste collection vehicles, whether front loading or rear loading vehicles, or side loading waste collection vehicles are not equipped to handle containers for both recyclable and non-recyclable waste. Recyclable waste containers and non-recyclable waste containers often require different mechanisms for waste collection vehicles to lift, hold, and empty the different containers. Accordingly, entities, such as municipalities, can be forced to choose between recyclable and non-recyclable waste collection, especially for designated bulk commercial waste locations. A forced choice between collection of recyclable and non-recyclable materials can be made more expensive, less convenient, and can lead to reduced collection of recyclable materials. 
     Therefore, a need exists for making the collection, storage, and transfer of waste, including recyclable waste in particular, less expensive and more convenient, for all types of waste collection vehicles. A solution to the above-mentioned needs can include providing a device that integrates a first container for non-recyclable waste, a second container for recyclables, and a method, structure, or both that facilitates the collection of waste from the first container and second container that can be compatible with existing infrastructure, such as a standard fork lift-operated waste collection vehicles or other vehicles. As discussed in greater detail below in relation to the FIGs., the device comprising first and second containers can allow a truck operator to selectively collect either waste or recycling based solely on the position of the forks. 
     Referring to the figures, a dual waste collection device for recyclable waste and non-recyclable waste is disclosed, which is also referred to as a dual recyclables and non-recyclable waste collection device. The dual recyclables and non-recyclable waste collection device can provide a bulk waste collection bin comprising two or more separate containers or compartments. The two or more separate containers can comprise a first container for recyclables and a second container for non-recyclable waste. A size, shape, weight, and various dimensions of the dual waste collection device can be standardized or conventional, so as to be seamlessly integrated with existing waste management or trash collecting infrastructure, such as, e.g., garbage trucks and recycling trucks. 
     Referring to  FIGS. 1A-3B , the dual recyclables and non-recyclable waste collection device  10 A (hereinafter device  10 A) has a first container  12  and a second container  14 . More specifically, the waste collection device  10 A is described below with reference to the various views presented in  FIGS. 1A-3B .  FIG. 1A  shows an elevated perspective view,  FIG. 1B  shows a side view, and  FIG. 1C  shows a top view of the device of  FIG. 1A .  FIG. 2A  shows an elevated perspective view of the first container of the device of  FIG. 1A , while  FIG. 2B  shows a front view of the first container of the device of  FIG. 1A .  FIG. 3A  shows an elevated perspective view of the second container of the device of  FIG. 1A , while  FIG. 3B  is a front view of the second container of the device of  FIG. 1A . 
     As shown in  FIGS. 1A-3B , either container  12  or  14  can house recyclables or non-recyclables. For further discussion, the first container  12  is used for recyclable waste collection and the second container  14  is used for non-recyclable waste collection. The first container  12  and second container  14  are generally made out of a sturdy metallic material such as steel or the like. However, other materials can be used without departing from the spirit and scope of the present disclosure. 
     The first container  12  and second container  14  can comprise lids  12 A and  14 A. One or more side doors  12 B can also be formed on the first container  12  and second container  14 . In the present embodiment, side doors  12 B are only formed in the first container  12 . However, side doors  12 B can be formed on first container  12 , the second container  14 , or both. 
     In the embodiment shown in  FIGS. 1A-3B , the first container  12  has an angled front surface  12 C and the second container  14  has an angled rear surface  14 C. The front surface  12 C and the rear surface  14 C are approximately parallel to one another. The angle of the front surface  12 C and the rear surface  14 C allow the first container  12  to more easily be raised and lifted away from the second container  14 . The angle of the front surface  12 C and the rear surface  14 C further makes it easier to better align the first and second containers  12  and  14  so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The first container  12  can comprise a pair of sleeves  16 . The pair of sleeves  16  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  16  is attached to each side section of the first container  12 . The pair of sleeves  16  can extend away from the first container  12 . By extending the pair of sleeves  16  away from the first container  12 , the pair of sleeves  16  forms a guide for the placement of the second container  14  and allow for the forks of a standard garbage truck to fully engage the sleeves for lifting of the first container. The pair of sleeves  16  can comprise a hollow channeling  16 A. The hollow channeling  16 A allows for a standard fork lift-operated waste collection vehicle to insert the fork through the pair of sleeves  16  to raise and empty the first container  12 . 
     The second container  14  can comprise a pair of sleeves  18 . The pair of sleeves  18  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  18  is attached to each side section of the second container  14  and below the pair of sleeves  16  on the first container  12 . The pair of sleeves  18  can comprise a hollow channeling  18 A. 
     Each sleeve  16  can comprise another sleeve  21  coupled to the underside of the sleeve  16 . Sleeve  21  is formed to comprise an open central section. Thus, below each end of the sleeve  16  can be the sleeve  21  with the central area below sleeve  16  open. The pair of sleeves  21  is in alignment with the second pair of sleeves  18  on the second container  14 . The central area of sleeve  21  is opened and spaced to enable the pair of sleeves  18  of the second container  14  in between the opening. The sleeve  21  serves two purposes. First, sleeve  21  is used in combination with sleeves  18  to simultaneous lift the two containers  12  and  14  without movement of the two containers  12  and  14  with respect to one another. Second, the opening in sleeves  21  are used as an alignment device when placing the first container  12  back in position so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The second pair of sleeves  18  is formed to comprise angled side edges. Sleeves  21  also comprise angled side edges so that the side edges of sleeves  18  run approximately parallel with the side edges of sleeves  21 . The angled sides edges of the sleeves  18  and  21  further serve as alignment mechanisms when placing the first container  12  back in position so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The second container  14  can comprise an additional pair of sleeves  23 . The sleeves  23  are spaced from the pair of sleeves  18  to enable placement of the pair of sleeves  21  of the first container  12  between the pairs of sleeves  18  and  23 . Accordingly, the four pairs of sleeves  16 ,  18 ,  21 , and  23  can be in alignment when the device  10 A is in its resting position, and can prevent movement of the containers  12  and  14  with respect to one another upon simultaneous lifting of the containers  12  and  14 . 
     Since in this embodiment the device  10 A enables simultaneous lifting of the two containers  12  and  14 , device  10 A can also include a locking device  59  to secure the lid  12 A of the first container  12 . This can allow the emptying of only second container  14  when simultaneous lifting of the two containers  12  and  14  for emptying. The first container  12  can still be lifted and emptied individually like in the previous embodiment. 
     In the present embodiment, the locking mechanism  59  for lid  12 A is a latch  64 . The latch  64  is hingedly coupled to the front surface  12 C of the first container  12 . The latch  64  has a hook  66  which can engage the lid  12 A to lock the lid  12 A when the first container  12  and second container  14  are positioned together. When the first container  12  and second container  14  are lifted together, the second container  14  can press the latch  64 , rotating it upwards and towards the front surface  12 C and lid  12 A, so that the hook  66  can engage and lock the lid  12 A. Thus, the lid  12 A can remain closed when both the first container  12  and second container  14  are lifted together. When the forks of a standard dump truck pass through the pair of sleeves  16  to lift just the first container  12  slightly above the second container  14 , the angle of the front surface of the first container causes the latch  64  to fall forward and away from front surface  12 C and lid  12 A so that the hook disengages the lid  12 A. This unlocks the lid  12 A thereby allowing the lid  12 A to open when the first container  12  is emptied. 
     In the present embodiment, rollers  68  are placed on the interior side of the sleeves  16 . The rollers  68  are positioned on the section of the sleeves  16  that extend away from the first container  12 . The rollers  68  are used to allow the first container  12  to more easily be lifted away from and realigned with the second container  14 . 
     A handle  70  can be attached to the lid  14 A of the second container  14 . The handle  70  is used to raise the lid  14 A to insert any refuse into the second container  14 . 
     Referring to  FIGS. 4A-6C , another embodiment of the device  10 B is shown. More specifically, the waste collection device  10 B is described below with reference to the various views presented in  FIGS. 4A-6C .  FIG. 4A  shows an elevated perspective view of another embodiment of the device  10 B.  FIG. 4B  shows a top view of the device of  10 B.  FIG. 4C  shows a front view of the device  10 B.  FIG. 5A  shows an elevated perspective view of the first container of the device  10 B.  FIG. 5B  shows a side view of the first container of the device  10 B.  FIG. 5C  is a front view of the first container of the device  10 B.  FIG. 6A  is an elevated perspective view of the second container of the embodiment of the device  10 B.  FIG. 6B  is another elevated perspective view of the second container of the embodiment of the device  10 B.  FIG. 6C  is a front view of the second container of the embodiment of the device  10 B. 
     As in the previous embodiment, the device  10 B can comprise a first container  12  and a second container  14 , where similar element number represent similar or identical features. The first container  12  and second container  14  can comprise lids  12 A and  14 A. Side doors  12 B can also be formed on the first container  12  and second container  14 . 
     The first container  12  can comprise an angled front surface  12 C and the second container  14  has an angled rear surface  14 C. The front surface  12 C and the rear surface  14 C are approximately parallel to one another. The angle of the front surface  12 C and the rear surface  14 C allow the second container  14  to more easily be raised and lifted away from the first container  12 . The angle of the front surface  12 C and the rear surface  14 C further makes it easier to better align the first and second containers  12  and  14  so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The first container  12  can comprise a pair of sleeves  71 . The pair of sleeves  71  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  71  is attached to each side section of the first container  12 . The pair of sleeves  71  can comprise a hollow channeling  71 A. The hollow channeling  71 A allows for a standard fork lift-operated waste collection vehicle to insert the fork through the pair of sleeves  71 . Note that the hollow channels need not fully encapsulate the forks or be of exact size and shape as shown in the embodiment to function in the manner shown. Any one skilled in the art would recognize, for instance, that the exterior side surfaces of the sleeves are not needed as the forks keep the container from moving side to side beyond the sleeves. 
     The second container  14  can comprise a pair of sleeves  73 . The pair of sleeves  73  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  73  is attached to each side section of the second container  14  and above the pair of sleeves  71  on the first container  12 . The pair of sleeves  73  can extend away from the second container  14  towards the first container  12 . By extending the pair of sleeves  73  away from the second container  14 , the pair of sleeves  73  forms a guide for the placement of the second container  14 . The pair of sleeves  73  can comprise a hollow channeling  73 A. 
     Each sleeve  73  can comprise another sleeve  75  coupled to the underside of the sleeve  73 . Sleeve  75  is formed to comprise an open central section. Thus, below each end of the sleeve  73  can be the sleeve  75  with the central area below sleeve  73  open. The pair of sleeves  75  is in alignment with the pair of sleeves  71  on the first container  14 . The central area of sleeve  75  is opened and spaced to enable the pair of sleeves  71  of the first container  12  in between the opening. The sleeve  75  serves two purposes. First, sleeve  75  is used in combination with sleeves  71  to simultaneous lift the two containers  12  and  14  without movement of the two containers  12  and  14  with respect to one another. Second, the opening in sleeves  75  are used as an alignment device when placing the second container  14  back in position so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The pair of sleeves  71  is formed to comprise angled side edges. Sleeves  75  also comprise angled side edges so that the side edges of sleeves  71  run approximately parallel with the side edges of sleeves  75 . The angled sides edges of the sleeves  71  and  75  further serve as alignment mechanisms when placing the second container  14  back in position so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     Since in this embodiment the device  10 B enables simultaneous lifting of the two containers  12  and  14 , device  10 B can also include a locking device  59 . However, in this embodiment, the locking device  59  is used to secure the lid  14 A of the second container  14 . This can allow the emptying of only the first container  12  when simultaneous lifting of the two containers  12  and  14  for emptying. 
     In the present embodiment, the locking mechanism  59  has one or more rod members  74  hingedly coupled to a top area of the front surface  14 D of the second container  14 . On one end of each rod member  74  is a hook  76 . The hook  76  engages the lid  14 A when the rod member  74  is in a first position thereby locking the lid  14 . When the rod member  74  is placed in a second position, the hook  76  disengages from the lid  14 A allowing one to lift the lid  14 A. Attached to a second end of the rod member  74  is a lever  78 . By pushing or pulling the lever  78 , one can lock and unlock the lid  14 A. It should be noted that the locking mechanism  59  of the present embodiment can be used with other embodiments of the disclosure. 
     In operation, when the forks of a standard dump truck pass through the pair of sleeves  73  to lift the second container  14  only, a cross member connecting the forks  25  can press against the lever  78  unlocking the lid  14 A so that the contents of the second container  14  can be emptied. When the forks  25  of the dump truck pass through the two sets of sleeves  75  and  71  the dump truck can simultaneous lift the two containers  12  and  14 . The locking mechanism  59  ensures that the contents of only the first container  12  can be emptied. 
     In this embodiment, an aligning mechanism  46  is used to properly align the first container  12  with the second container  14 . It should be noted that the alignment mechanism  46  can be used on any of the previous embodiments or any of the following embodiments for ensuring the alignment of the first container  12  with the second container  14 . 
     In the present embodiment, the aligning mechanism  46  can comprise a set of rollers  48  coupled to a rear surface  14 C of the second container  14 . A corresponding pair of guide rails  50  is coupled to the front surface  12 A of the first container  12 . When the first container  12  is lowered into position in proximity of the second container  14 , the rollers  48  can mate with the guide rails  50  thereby causing the two containers  12  and  14  to align. 
     In accordance with one embodiment, the pair of guiderails  50  can be slightly tapered so that the pair of guiderails  50  is closer in proximity to each other at the top of the first container  12  than at the bottom of the first container  12 . Accordingly, the pair of guiderails  50  can be wedged between opposite ends of the set of rollers  48  as the second container  14  is lowered into position in proximity of the first container  12  and thereby cause the two containers  12  and  14  to align. 
     In the present embodiment, rollers  68  are placed on the interior side of the sleeves  73 . The rollers  68  are positioned on the section of the sleeves  73  that extend away from the second container  14 . The rollers  68  are used to allow the second container  14  to more easily be lifted away from and realigned with the first container  12 . 
     Referring to  FIGS. 7A-9C , another embodiment of the device  10 C is shown. More specifically, the waste collection device  10 C is described below with reference to the various views presented in  FIGS. 7A-9C .  FIG. 7A  shows an elevated perspective view of another embodiment of the device of the present disclosure.  FIG. 7B  shows a side view of the device  10 C.  FIG. 7C  shows a front view of the device  10 C.  FIG. 8A  shows an elevated perspective view of the first container of the device  10 C.  FIG. 8B  shows a front view of the first container of the device  10 C.  FIG. 9A  shows an elevated perspective view of the second container of the device  10 C.  FIG. 9B  shows a front view of the second container of the device  10 C.  FIG. 9C  shows a top view of the second container of the device  10 C. 
     For device  10 C, either container  12  or  14  can house recyclables or non-recyclables. The first container  12  and second container  14  are generally made out of a sturdy metallic material such as steel or the like. However, other materials can be used without departing from the spirit and scope of the present disclosure. 
     The first container  12  and second container  14  can comprise lids  12 A and  14 A. Side doors  12 B can also be formed on the first container  12  and second container  14 . In the some embodiments, side doors  12 B can be formed only in tone container, such as the first container  12 . However, side doors  12 B can be formed on the first container  12 , the second container  14 , or both. 
     The first container  12  has an angled front surface  12 C and the second container  14  has an angled rear surface  14 C. The front surface  12 C and the rear surface  14 C are approximately parallel to one another. The angle of the front surface  12 C and the rear surface  14 C allow the first container  12  to more easily be raised and lifted away from the second container  14 . The angle of the front surface  12 C and the rear surface  14 C further makes it easier to better align the first and second containers  12  and  14  so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The first container  12  can comprise a pair of sleeves  16 . The pair of sleeves  16  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  16  is attached to each side section of the first container  12 . The pair of sleeves  16  can extend away from the first container  12 . By extending the pair of sleeves  16  away from the first container  12 , the pair of sleeves  16  forms a guide for the placement of the first container  12  with respect to the second container  14 . The pair of sleeves  16  can comprise a hollow channeling  16 A. The hollow channeling  16 A allows for a standard fork lift-operated waste collection vehicle to insert the fork through the pair of sleeves  16  to raise and empty the first container  12 . Note that the hollow channels need not fully encapsulate the forks or be of exact size and shape as shown in the embodiment to function in the manner shown. Any one skilled in the art would recognize, for instance, that the exterior side surfaces of the sleeves are not needed as the forks keep the container from moving side to side beyond the sleeves. 
     The second container  14  can comprise a pair of sleeves  18 . The pair of sleeves  18  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  18  is attached to each side section of the second container  14  and below the pair of sleeves  16  of the first container  12 . The pair of sleeves  18  can comprise a hollow channeling  18 A. The hollow channeling  18 A allows for a standard fork lift-operated waste collection vehicle to insert the fork through the pair of sleeves  16  to raise and empty the second container  14 . Note that while pairs of sleeves  16  and  18  are shown comprising hollow channeling  18 A, hollow channeling  18 A and pairs of sleeves  16  and  18  can also be formed with openings, slats, windows, voids, hoops, or rings, such that they do not fully encapsulate the forks once the forks are inserted within the sleeve. An amount of material used for pairs of sleeves  16  and  18 , including sizing and spacing can be determined based on desirable strength requirements for lifting and emptying the first container  12  and the second container  14 , as well as for ease of use in inserting forks within the sleeves. As such, pairs of sleeves  16  and  18 , or any sleeve, can be formed comprising a generally rectangular shape that further comprises a square or rectangular cross-section, as shown in the figures, but can also comprise any geometric or cross-sectional shape. In some instances, sleeves can be formed of one or more planar two-dimensional surfaces, such as the top or top and bottom surfaces of hollow channeling  18 A without comprising an exterior side surface. In such instances, the exterior side surfaces can be omitted in that the forks inserted within the sleeves and used to raise the containers are rigidly set at a fixed distance and will not contact the exterior side surfaces of hollow channeling  18 A. Sleeves  18  can comprise any suitable length, and can extend partially or completely along a side of the container to which they are attached. As shown in  FIGS. 7A-9C , the sleeves  18  can extend approximately a length of the side section  14 B of the container. 
     In order to further aid the ability to raise, lift away and realign the first container  12  and the second container  14 , one or more rollers  15  can be placed on the outer perimeter of the front surface  12 C of the first container  12 . The rollers  15  can prevent the front surface  12 C of the first container  12  from damaging the rear surface  14 C by allowing the first container  12  to roll on the second container  14  during emptying of the first container  12 . The rollers  15  further act as a bumper when repositioning the second container  14  after emptying the second container  14 . 
     In the present embodiment, rollers  68  are placed on the interior side of the sleeves  16 . The rollers  68  are positioned on the section of the sleeves  16  that extend away from the first container  12 . The rollers  68  are used to allow the first container  12  to more easily be lifted away from and realigned with the second container  14 . 
     A handle  70  can be attached to the lid  14 A of the second container  14 . The handle  70  is used to raise the lid  14 A to insert any refuse into the second container  14 . 
     Referring now to  FIGS. 10A-10B , another alternative embodiment of device  10 A is shown that further comprises aligning mechanism  46 . In the present embodiment, the aligning mechanism  46  takes the form of interlocking corrugated front and rear surfaces  12 C and  14 C respectively.  FIG. 10A  shows an elevated perspective view of the aligning mechanism  46 , and  FIG. 10B  shows a top view of the aligning mechanism  46 . As shown in  FIGS. 10A-10B  front and rear surfaces  12 C and  14 C can comprise corresponding notches  96  and tabs  98  which help to align the first and second containers  12  and  14 . 
     Referring to  FIGS. 11A-11C , another embodiment of the device  10 D is shown comprising a first container  12  and a second container  14 . More specifically, the waste collection device  10 C is described below with reference to the various views presented in  FIGS. 11A-11C .  FIG. 11A  shows an elevated perspective view of a device  10 D comprising an alignment mechanism of bottom rails.  FIG. 11B  shows a side view of the device  10 D.  FIG. 11C  shows a side view of the device  10 D with the first container raised. The first container  12  and second container  14  are generally made out of a sturdy metallic material such as steel or the like. However, other materials can be used without departing from the spirit and scope of the present disclosure. 
     The first container  12  and second container  14  can comprise lids  12 A and  14 A. Side doors  12 B can also be formed on the first container  12  and second container  14 . As a non-limiting example,  FIGS. 11A and 11B  show side doors  12 B can be formed only in the first container  12 . However, the side door  12 B can also be formed on the first container  12 , the second container  14 , or both. 
     In the present embodiment, the first container  12  has an angled front surface  12 C and the second container  14  has an angled rear surface  14 C. The front surface  12 C and the rear surface  14 C are approximately parallel to one another. The angle of the front surface  12 C and the rear surface  14 C allow the first container  12  to more easily be raised and lifted away from the second container  14 . The angle of the front surface  12 C and the rear surface  14 C further makes it easier to better align the first and second containers  12  and  14  so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The first container  12  can comprise a pair of sleeves  16 . The pair of sleeves  16  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  16  is attached to each side section of the first container  12 . The pair of sleeves  16  can extend away from the first container  12 . By extending the pair of sleeves  16  away from the first container  12 , the pair of sleeves  16  forms a guide for the placement of the first container with respect to the second container  14 . The pair of sleeves  16  can comprise a hollow channeling  16 A. The hollow channeling  16 A allows for a standard fork lift-operated waste collection vehicle to insert the fork through the pair of sleeves  16  to raise and empty the first container  12 . Note that the hollow channels need not fully encapsulate the forks, as described above. 
     The second container  14  can comprise a pair of sleeves  18 . The pair of sleeves  18  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  18  is attached to each side section of the second container  14  and below the pair of sleeves  16  on the first container  12 . The pair of sleeves  18  can comprise a hollow channeling  18 A. The sleeves  18  generally run a length of the side section  14 B. 
     Each sleeve  16  can comprise another sleeve  81  coupled to the underside of the sleeve  16 . Below a first end of the sleeve  16  can be the sleeve  81 . The sleeves  81  are in alignment with the second pair of sleeves  18  on the second container  14 . The sleeve  81  is used in combination with sleeves  18  to simultaneous lift the two containers  12  and  14  without movement of the two containers  12  and  14  with respect to one another. 
     Since in this embodiment the device  10 D enables simultaneous lifting of the two containers  12  and  14 , device  10 D can also include a locking device  59  to secure the lid  12 A of the first container  12 . This can allow the emptying of only second container  14  when simultaneous lifting of the two containers  12  and  14  for emptying. The first container  12  can still be lifted and emptied individually like in the previous embodiment. 
     In the present embodiment, the locking device  59  is a latch  64 . The latch  64  is hingedly coupled to the front surface  12 C of the first container  12 . The latch  64  has a hook  66  which can engage the lid  12 A to lock the lid  12 A when the first container  12  and second container  14  are positioned together. When the first container  12  and second container  14  are lifted together, the second container  14  can press the latch  64 , rotating it upwards and towards the front surface  12 C and lid  12 A, so that the hook  66  can engage and lock the lid  12 A. Thus, the lid  12 A can remain closed when both the first container  12  and second container  14  are lifted together. When the forks of a standard dump truck pass through the pair of sleeves  16  to lift just the first container  12  slightly above the second container  14 , the angle of the front surface of the first container causes the latch  64  to fall forward so that the hook disengages the lid  12 A. This unlocks the lid  12 A thereby allowing the lid  12 A to open when the first container  12  is emptied. 
     In the present embodiment, rollers  68  are placed on the interior side of the sleeves  16 . The rollers  68  are positioned on the section of the sleeves  16  that extend away from the first container  12 . The rollers  68  are used to allow the first container  12  to more easily be lifted away from and realigned with the second container  14 . 
     The second container  14  can also comprise a pair of support members  58  attached to its bottom for placement of the first container  12  upon during its resting position. The support members  58  are angled upwardly away from the second container  14  thereby providing an additional mechanism for aligning the first and second containers  12  and  14  and for preventing movement of the two containers  12  and  14  with respect to one another during simultaneous lifting of the two containers  12  and  14 . 
     Referring now to  FIGS. 12A-14 , another embodiment of the device  10 E is disclosed. More specifically, the waste collection device  10 E is described below with reference to the various views presented in  FIGS. 12A-14 .  FIG. 12A  shows an elevated perspective view of device  10 E comprising an alignment mechanism of side rails.  FIG. 12B  shows another elevated perspective view of device  10 E.  FIG. 13  shows an elevated perspective view of the first container of the device  10 E.  FIG. 14  shows an elevated perspective view of the second container of the device  10 E. 
     The device  10 E still has a first container  12  and a second container  14 . The first container  12  can be capable of being lifted individually from the second container  14  while also being capable of being lifted simultaneously with the second container  14 . 
     The first container  12  can comprise a pair of sleeves  16  positioned in a like manner as in the previous embodiment. The pair of sleeves  16  enables lifting of the first container  12  by itself. The second container can still comprise a pair of sleeves  18  positioned in like manner as in the previous embodiment. 
     In the present embodiment, the first container  12  can also comprise a pair of locking plates  80 . The locking plates  80  are attached to the side surfaces of the first container  12  and aligned with a bottom surface of the sleeves  18 . The locking plates  80  keep the first container  12  from sliding up off of the second container  14  when both the first and second containers are lifted. When the forks of a standard dump truck pass through the sleeves  18 , the bottom of the forks can engage the locking plates  80  preventing the first container  12  from sliding up off of the second container  14  when both the first and second containers are lifted. 
     Since in this embodiment the device  10 E enables simultaneous lifting of the two containers  12  and  14 , device  10 E can also include a locking device  59  to secure the lid  12 A of the first container  12 . This can allow the emptying of only first container  12  when simultaneous lifting of the two containers  12  and  14  for emptying. 
     In this embodiment, a roller assembly  82  is attached to bottom corners of the front surface  12 A of the first container  12 . The roller assembly  82  has a pair of plate members  84  attached to the bottom corners of the first surface  12 A. A set of rollers  86  is attached to the plate members  84 . When the first container  12  is lowered into its resting position in proximity to the second container  14 , the rollers  86  engage guide rails  90  and the side surfaces of the second container  14  thereby bringing the first container  12  in alignment with the second container  14 . 
     Rollers  68  are placed on the interior side of the sleeves  16 . The rollers  68  are positioned on the section of the sleeves  16  that extend away from the first container  12 . The rollers  68  are used to allow the first container  12  to more easily be lifted away from and realigned with the second container  14 . 
     Referring to  FIGS. 15A-17B , another embodiment of the device  10 F is shown, in which the device  10 F is configured to be lifted from the bottom. More specifically, the waste collection device  10 F is described below with reference to the various views presented in  FIGS. 15A-17B .  FIG. 15A  shows a perspective view of another embodiment of the device  10 F.  FIG. 15B  shows a bottom perspective view of the device  10 F with the second container raised.  FIG. 15C  shows a side view of the device  10 F showing the second container in a lowered position and in a raised position and lid locking mechanism.  FIG. 15D  shows a top view of the device  10 F.  FIG. 16A  shows a perspective view of the second container of the device  10 F.  FIG. 16B  shows a side view of the second container of the device  10 F.  FIG. 17A  shows a perspective view of the first container of the device  10 F.  FIG. 17B  shows a side view of the first container of the device  10 F. 
     The device  10 F has a first container  12  and a second container  14 . The first container  12  and second container  14  are generally made out of a sturdy metallic material such as steel or the like. However, other materials can be used without departing from the spirit and scope of the present disclosure. 
     The first container  12  and second container  14  can comprise lids  12 A and  14 A. Side doors  12 B can also be formed on the first container  12  and second container  14 . In the present embodiment, side doors  12 B are only formed in the first container  12 . However, side doors  12 B can be formed on the first container  12 , the second container  14 , or both. 
     In the present embodiment, the first container  12  has an angled front surface  12 C and the second container  14  has an angled rear surface  14 C. The front surface  12 C and the rear surface  14 C are approximately parallel to one another. The angle of the front surface  12 C and the rear surface  14 C allow the second container  14  to more easily be raised and lifted away from the first container  12 . The angle of the front surface  12 C and the rear surface  14 C further makes it easier to better align the first and second containers  12  and  14  so that there is a minimal gap between the front surface  12 C and the rear surface  14 C of the first and second containers  12  and  14 . 
     The first container  12  can comprise a pair of sleeves  92 . The pair of sleeves  92  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  92  is attached to an outer edge on a bottom surface of the first container  12 . The pair of sleeves  92  can extend away from the first container  12 . The pair of sleeves  92  can comprise a hollow channeling  92 A. The hollow channeling  92 A allows for existing fork lift-operated waste collection vehicle to insert the fork through the pair of sleeves  92 . 
     The second container  14  can comprise a pair of sleeves  96 . The pair of sleeves  96  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  96  is attached to an outer edge on a bottom surface of the second container  14 . The pair of sleeves  96  can comprise a hollow channeling  96 A. The sleeves  92  of the first container  12  are in alignment with the sleeves  96  on the second container  14  when the first container  12  and second container  14  are properly aligned. The sleeve  92  is used in combination with sleeves  96  to simultaneous lift the two containers  12  and  14  without movement of the two containers  12  and  14  with respect to one another. 
     The second container  14  can comprise a pair of sleeves  94 . The pair of sleeves  94  is generally made out of the same material as the first and second containers  12  and  14 . An individual sleeve of the pair of sleeve members  94  is attached to the bottom surface of the second container  14  and next to a sleeve  96 . In the present embodiment, the pair of sleeve members  94  is positioned on the bottom surface of the second container  14  and adjacent to and inwardly from the sleeves  96 . The pair of sleeves  94  can comprise a hollow channeling  94 A. The length of each of the pair of sleeves  94  generally does not exceed the length of the second container  14 . An end cap  94 B is generally placed at the end of each sleeve  94 . The sleeves  94  are used to lift the second container  14  up and away from the first container  12  to individually empty the second container  14 . 
     Since in this embodiment the device  10 F enables simultaneous lifting of the two containers  12  and  14 , device  10 F can also include a locking device  59  to secure the lid  14 A of the second container  14 . This can allow the emptying of only first container  12  when simultaneous lifting of the two containers  12  and  14  for emptying. The second container  14  can still be lifted and emptied individually like in the previous embodiment. 
     In the present embodiment, the locking mechanism  59  has one or more rod members  74  hingedly coupled to a top area of the front surface  14 D of the second container  14 . On one end of each rod member  74  is a hook  76 . The hook  76  engages the lid  14 A when the rod member  74  is in a first position thereby locking the lid  14 . When the rod member  74  is placed in a second position, the hook  76  disengages from the lid  14 A allowing one to lift the lid  14 A. 
     Attached to a second end of the rod member  74  is a plate  98 . The plate  98  is positioned in front of the sleeves  96 . When the forks of the dump truck push the plate  98 , it rotates upwards. A linkage  105  (rod, chain, belt, etc.) is attached to the shaft of the plate  98 . When the plate rotates upwards, it pulls the linkage  105 , which in turn, pulls the hook closed, locking the lid  14 A of the second container  14 . 
     When emptying just the second container  14 , the truck forks slide into the sleeves  94 . The locking mechanism  59  can be un-engaged so the lid  14 A is free to swing open when emptied. The sleeves  94  comprise end caps  94 B on the back side so that the forks cannot protrude out the back of the second container  14  and so that the second container  14  does not slide down the forks as it is being emptied. Without this feature, the second container  14  would slide down the forks and the forks would hit the first container  12  when the second container  14  was lowered back into place. 
     The first container  12  can also comprise a pair of support members  58  attached to its bottom for placement of the second container  14  upon during its resting position. The support members  58  are angled upwardly away from the second container  14  thereby providing an additional mechanism for aligning the first and second containers  12  and  14  and for preventing movement of the two containers  12  and  14  with respect to one another during simultaneous lifting of the two containers  12  and  14 . 
     In the present embodiment, a set of rollers  102  can be coupled to a rear surface  14 C of the second container  14 . The rollers  102  are used to help lift the second container  14  up and away from the first container  12 . The rollers  102  can be used with guide rails  104  to properly align the first and second containers  12  and  14  respectively. 
       FIGS. 18A-18E  show a non-limiting example of a dual waste collection device  200 , similar to devices  10 A- 10 F discussed above, which can similarly be used for the collection, storage, and transfer, of both recyclable waste material and non-recyclable waste material.

FIG. 18C  shows a front perspective view of the first container of the device  200  comprising a detail view A of a lid locking mechanism.  FIG. 18D  shows a front perspective view of the second container of the device  200 .  FIG. 18E  shows a rear perspective view of the second container of the device  200 . 
     Similar to devices  10 A- 10 F, the dual waste collection device  200  can comprise more than one container, such as two containers including a first container  202  and a second container  204 . As shown in  FIG. 18A , the first container can be disposed as a rear container and the second container  204  can be disposed as front container when considered with respect to a preferred relative positioning of the first container  202  and the second container  204  with respect to a waste collection vehicle used in to empty the first and second containers. Both first container  202  and second container  204  can contain, or can be designated to contain such as by one or more of color, text, symbols, or other indicators, either recyclable material or non-recyclable material. 
     For convenience of discussion, the first container  202  will be referred to herein as being for collection of recyclable waste and the second container  204  will be referred to as being for collection of non-recyclable waste. However, the respective designations of first container  202  and second container  204  for recyclable and for non-recyclable waste could also be reversed. The reversal of device designations with respect to recyclable waste and non-recyclable waste is equally applicable to all the other devices and containers described herein. The designation of what materials are considered recyclable waste and what materials are considered non-recyclable waste can be relative, such that a particular material that might be considered recyclable in one jurisdiction could simultaneously be considered non-recyclable in another jurisdiction. In such instances, relative differences in recycling programs can be accommodated by specifying to users where each type of waste should be deposited. 
     The first container  202  and the second container  204  can be made of and comprise one or more materials that are strong, sturdy, and weather resistant, such as metal, plastic, fiberglass or other suitable material, whether synthetic or natural. The first container  202  and the second container  204  can be made of the same or different materials, such as steel, stainless steel, or other suitable metal, with or without paint. Of course, other materials can also be used without departing from the spirit and scope of the present disclosure. Containers  202 ,  204 , and any of the other containers disclosed herein, can without limitation, comprise bottom surfaces or panels comprising a thickness in a range of 2.9-2.3 millimeters (mm) plus or minus 1-2 mm, such as a thickness of 9-11 gauge or 10 gauge. Similarly, the containers can further comprise side surfaces or panels comprising a thickness in a range of 2.3-1.8 mm plus or minus 1-2 mm, such as a thickness of 11-13 gauge or 12 gauge. 
     The first container  202  and the second container  204  can comprise lids  206  and  208 , respectively, that cover openings in the containers and isolate the containers. Isolation of the first container  202  by lid  206  and of the second container  204  by lid  208  can control or regulate entry of waste materials, and limit an inner area of the container, including waste being stored within the container, from exposure or contact with animals, environmental conditions such as precipitation, or both. Lids  206  and  208  can also provide odor control and prevent material from being removed from the containers, such as by wind. Lids  206  and  208  can be formed in any number, size, or orientation to correspond with and be mateably coupled to the openings in the first and second containers, and can be made in one or more section, portions, or pieces. For example,  FIG. 18A  shows lid  206  formed of a single planar or element, while lid  208  comprises first and second corrugated elements. Lids  206  and  208  can comprise one or more materials that are the same, similar, or different than the materials comprising first container  202  and second container  204 , such as materials that are strong, sturdy, and weather resistant, such as metal, plastic, fiberglass, wood, or other suitable material, whether synthetic or natural, painted or not. Lids can be removably or permanently coupled to their respective containers such as by hinges, pins, rails, slides, pivots, rings, hooks, or any other suitable attachment device. Movement and position of lids  106  and  108  can be positioned or controlled so as to prevent movement of the lids at undesirable locations to cover access points, and from occurring at undesirable times, such as during emptying of the container by a waste management vehicle. 
     First container  202  and second container  204  can comprise one or more openings, each of which can be accessed by one or more lids.  FIGS. 18A-18C  provide a non-limiting example in which first container  202  comprises as least one side opening in a side wall of the container in addition to a main opening at a top of the container. As shown in  FIGS. 18A-18C , the opening in the side of first container  202  can be covered by a side-door or lid  210 , which can be similar or identical to lids  206  and  208 . In an embodiment, side-door  210  can removably cover an opening or access point in only the first container  202  and not the second container  204 . However, one or more similar openings and side doors  210  can also be formed in second container  204 , the first container  202 , or both. 
     As shown in  FIGS. 18A-18C , front surface  212  of the first container  202  can comprise a relative angle that is not perpendicular, at a right angle, or 90 degrees. While in some instances the relative angle between a bottom surface and the front surface  212  can be perpendicular, in other instances, the relative angle between the bottom surface and the front surface  212  can be an acute angle or an obtuse angle to help facilitate relative movement between the first container  202  and the second container  204  when one container is lifted by itself to allow for emptying of its content without lifting or emptying content of the other container. In some instances, the relative angle of the front surface  212  can differ from perpendicular by plus or minus a measure that is less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more. The relative angle can be measured between a bottom surface of the first container  202  and the front surface  212  of the first container  202 . Alternatively, the relative angle can be measured between a surface on which the first container  202  is resting and the front surface  212 . 
     Similarly, the second container  204  can comprise a rear surface  214  that is oriented toward, and situated opposite from, front surface  212  of first container  20  when the first container  202  and the second container  204  are releasably coupled together as device  200 . As such, rear surface  214  can comprise a relative angle that is not perpendicular, at a right angle, or at 90 degrees. While in some instances the relative angle between a bottom surface and the rear surface  214  can be perpendicular, in other instances, the relative angle between the bottom surface and the rear surface  214  can be an acute angle or an obtuse angle to help facilitate relative movement between the first container  202  and the second container  204  when one container is lifted by itself to allow for emptying of its content without lifting or emptying content of the other container. In some instances the relative angle of the rear surface  214  can differ from perpendicular by plus or minus a measure that is less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more. The relative angle can be measured between a bottom surface of the second container  204  and the rear surface  214  of the second container  204 . Alternatively, the relative angle can be measured between a surface on which the first container  204  is resting and the rear surface  214 . 
     In any event, the relative angle of the front surface  212  can be complimentary with rear surface  214  so that together the sum of the angles is equal to, or substantially equal to, 180 degrees, such as plus or minus 5 degrees. As such, the front surface  212  and the rear surface  214  can be parallel or approximately parallel with respect to each other another when releasably coupled to each other to form device  200 , or when device  200  is at rest on a level surface for use, with sleeves of the first container  202  aligned with sleeves of the second container  204 . The non-perpendicular angles of the front surface  212  and the rear surface  214  can allow for the first container  202  to more easily be raised and lifted away from the second container  204 . The angle of the front surface  212  and the rear surface  214  further makes it easier to better align the first and second containers  202  and  204  so that there is a minimal gap between the front surface  212  and the rear surface  214  of the first and second containers  202  and  204 , respectively. 
     Device  200  can comprise a plurality of sleeves coupled to, or integrally formed with, one or more outer surfaces of the device  200 . The plurality of sleeves can comprise or be formed of one or more layers of material. The plurality of sleeves can also be formed as one or more pairs of sleeves configured for receiving forks of a waste collection vehicle such as a garbage truck, thereby facilitating removal or collection of waste material from the device  200 . Waste can be transferred from the device  200  to the waste collection vehicle by inserting forks of the waste collection vehicle into sleeves of the device  200 , then lifting the device  200  and emptying contents of the device  200  into a storage or transfer container coupled to the waste collection vehicle. 
     As a non-limiting example, the device  200  can comprise multiple pairs of sleeves coupled to the first container  202  and the second container  204 . For convenience relative positions of the sleeves are referred to as left and right sleeves to designate a relative position of sleeves from a point of view of a waste collection vehicle aligned with the device  200  for emptying the device  200 . Relative positions of the sleeves are referred to as inner and outer sleeves, with the inner sleeves being those sleeves that are closest to exterior surfaces or sidewalls of the device  200 , and the outer sleeves being those that are farthest from the exterior surfaces or sidewalls of the device  200 . Stated another way, the inner sleeves can be disposed between or sandwiched between the outer sleeves and the exterior surface or sidewall of the device  200 , including the first container  202  and the second container  204 . 
     The first container  202  can comprise a first pair of sleeves comprising an outer left sleeve  216  and an inner right sleeve  218  and a second pair of sleeves comprising an inner left sleeve  220  and an outer right sleeve  222 . The pair of sleeves, including sleeves  216  and  218 , and pair of sleeves, including sleeves  220  and  222 , can be made of materials that are the same or similar as the materials used for the first and second containers  202  and  204 . By alternating an inner and outer position for the sleeves positioned on left and right sides of the first container  202  for the first pair of sleeves and the second pair of sleeves, a fixed or constant distance for each of the first and second pairs of sleeves is maintained. Maintaining the fixed or constant distance for both the first and second pairs of sleeves allows the same waste collection vehicle, such as a standard waste collection vehicle comprising forks with a fixed spacing or width, to be used for insertion into the first pair of sleeves, the second pair of sleeves, or both. As shown in  FIGS. 18A-18E , the first pair of sleeves comprising sleeves  216  and  218  can be used, e.g. have forks of a trash collection vehicle inserted therein, to lift or empty only the first container  202 . The second pair of sleeves comprising sleeves  220  and  222  cam be used to lift the first container  202  and the second container  204  together. 
     In some embodiments, all sleeves, such as sleeves  216 ,  218 ,  220 , and  222  can be aligned parallel or substantially parallel to each other, such as within less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more of each other. Similarly, the side surfaces of the first container  202  and the second container  204 , e.g., those surface disposed between and coupled to the front and back surfaces of the first container  202  and second container  204 , can be parallel or substantially parallel to each other. Advantageously, sizing and orientation of the sleeves will allow for the forks of the waste collection vehicle to be easily inserted within the sleeves for easy emptying of one or more containers within the device  200 . In some instances, the sleeves will comprise an alignment that is equal or substantially equal to an alignment of the sidewalls of the device  200 . The alignment or relative angle of the sidewalls of the first container  202  and the second container  204  (as seen in in a plan view) can be parallel. Alternatively, the alignment or relative angle of the sidewalls of the first container  202  and the second container  204  can be angled toward or away from each other, such that a relative angle of the sidewalls can differ from being parallel by plus or minus a measure that is less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more. In instances in which an angle of the sidewalls of the first container  202  and the second container  204  would prevent the sleeves from being parallel with the sidewalls and still provide for easy or acceptable access of the forks of the waste collection vehicle within the sleeves, the sleeve can be angled, instead of parallel, with respect to the container sidewalls. In such instances, a relative angle of the sidewalls can differ from the sidewalls by plus or minus a measure that is less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more. 
     As shown in  FIGS. 18A-18E , sleeves  216 ,  218 ,  220 , and  222  can be attached to, and extend away from, the side surfaces of the first container  202  to which they are attached. In extending away from the first container, the sleeves  216 ,  218 ,  220 , and  222  can pass through a plane containing front surface  212  of the first container  202 . As such, sleeves  216 ,  218 ,  220 , and  222  can be positioned for each to accept a fork of a waste collection vehicle. As indicated above, sleeves  216  and  220  can be coupled to a left sidewall of the container  202  while sleeves  218  and  222  can be coupled to a right sidewall of the container  202  such that the sleeves  216  and  220  are coupled on a surface of the device  202  opposite the surface to which the sleeves  218  and  222  are coupled. By extending the sleeves  216 ,  218 ,  220 , and  222  away from the first container  202 , such as passing through a plane containing front surface  212  of the first container  202 , the sleeves can form and serve as a guide for the placement of the second container  204  between the sleeves, while also allowing for the forks of a standard garbage truck to fully engage the sleeves for lifting of the containers. 
     As a non-limiting example,  FIG. 18C  shows an embodiment in which sleeves  216 ,  218 ,  220  and  222  can be coupled or directly attached to an outer surface of first container  202  so that one or more of the sleeves is disposed outside the waste collection area of the first container  202 . Alternatively, the sleeves of the first container  202 , or any part of device  200 , can be coupled or directly attached to an inner surface of first container  202  so that one or more of the sleeves is disposed inside the waste collection area of the first container  202 . When one or more sleeves are disposed or formed within the device  200 , access openings can be formed through at least a portion or surface of the device  200  such that forks of a waste collection vehicle can be disposed through the device  200  and into the sleeves. For example, access openings can be formed through a front surface  212  of the first container  202  to allow forks to be inserted into the interior sleeves. As shown in  FIG. 18C , sleeves  218  and  220  can be formed on outer surfaces of the container  202 . Sleeves  216  and  222  can be attached to the outward facing surfaces of sleeves  220  and  218 , respectively. Stated another way, sleeves  216  and  222  can be attached to surfaces of sleeve  220  and  218 , respectively, that are opposite the exterior surface of the first container  202 . 
     Any or all of the sleeves  216 ,  218 ,  220 , and  222  can comprise hollow channeling, such as hollowing channeling  217 ,  219 ,  221 , and  223 , respectively. The hollow channeling can allow for a standard fork lift-operated waste collection vehicle to insert forks through the pair of sleeves  216  and  218  to raise and empty the first container  202  individually when the forks are in a first position. The pair of sleeves  220  and  222  can comprise hollow channeling  221  and  223  that allows for forks to be inserted through the pair of sleeves  220  and  222  to lift the first container  202  and second container  204  together. Sleeves  216 ,  218 ,  220 , and  222 , as well as any of the other sleeves discussed herein, can comprise any suitable length, which in some instances comprise lengths in a range of 0.6-1.3 meters (m). Sleeves  216 ,  218 ,  220 , and  222  can extend partially or completely along a side or side surface of the container to which they are attached. 
     Note that while sleeves  216 ,  218 ,  220 , and  222  are shown comprising hollow channeling  217 ,  219 ,  221 , and  223 , respectively, the sleeves  216 ,  218 ,  220 , and  222  can also be formed with openings, slats, windows, voids, hoops, or rings, such that 216, 218, 220, and 222 do not fully encapsulate the forks once the forks are inserted within the sleeve. An amount of material used for sleeves  216 ,  218 ,  220 , and  222 , including sizing and spacing can be determined based on desirable strength requirements for lifting and emptying the first container  202  and the second container  204 , as well as for ease of use in inserting forks within the sleeves. As such, sleeves  216 ,  218 ,  220 , and  222 , or any sleeve, can be formed comprising metal with a thickness in a range of 3.66-2.38 mm plus or minus 1-2 mm, or about 7-10 gauge. Similarly, sleeves  216 ,  218 ,  220 , and  222 , or any sleeve, can be formed comprising a generally rectangular shape that further comprises a square or rectangular cross-section, as shown in the figures, but can also comprise any geometric or cross-sectional shape. In some instances the sleeves comprising a rectangular cross-section can comprise a height in a range of about 20-31 centimeters (cm) and a width in a range of about 10-21 cm, and as such can, without limitation, comprise height of 10.2 cm and a width of 22.9 cm. In some instances, sleeves  216 ,  218 ,  220 , and  222  can be formed of one or more planar two-dimensional surfaces, such as the top or the top and bottom surfaces of hollow channeling  217 ,  219 ,  221 , or  223  without comprising an exterior side surface. In such instances, the exterior side surfaces can be omitted in that the forks inserted within the sleeves and used to raise the containers are rigidly set at a fixed distance and will not contact the exterior side surfaces of hollow channeling  217 ,  219 ,  221 , and  223 . 
     One or more end caps, such as end cap  226 , can be coupled to, or integrally formed with, an end of a sleeve, such as sleeve  218 . The end cap can prevent a container, such as the first container  202 , from sliding down the forks of a waste collection vehicle as it is being emptied. Without an end cap, the first container  202  could slide down the forks of the waste collection vehicle while the first container  202  was being lifted and emptied. In the event that an end cap was not present and the container  202  did slide along the forks of the waste collection vehicle while being emptied the first container  202  could encounter difficulty in being lowered back into position behind the second container  204  after having slid while being emptied. 
     Moving from particular details of the sleeves coupled to the first container  202 , we now turn to a description of some details relating to the second container  204 . As shown in  FIGS. 18B, 18D, and 18E , the second container  204  can comprise a pair of sleeves  228 . The pair of sleeves  228  can be made out of materials that are the same, similar, or different from those forming sleeves  216 ,  218 ,  220 , and  222 , as well as the same, similar, or different from those forming the first and second containers  202  and  204 . The sleeves  228  can be coupled to a side surface of the second container  204 , and as such can be either directly attached to a side surface or sidewall of the second container  204 , to align with an inner sleeve  218  or  220  coupled to the first container  202 , or can be offset with respect to the side surfaces or sidewalls of the second container  204 , to align with an outer sleeve  216  or  222  coupled to the first container  202 . 
     As a non-limiting example, a first sleeve  228  can be attached to a side surface of the second container  204  and aligned with sleeve  220  attached to the first container  202  and positioned to accept a fork of a standard waste collection vehicle that can be inserted through both sleeve  228  and sleeve  220  at a same time. Another or second sleeve  228  can be coupled to the second container, such as to a sidewall opposite the surface to which the first sleeve  228  is coupled, by means of a stand-off, spacer, or offset device  230  that can be formed as a bracket, arm, flange, channel, or other suitable structure. Offset device  230  can be made of a material that is the same, similar, or different than sleeve  228  or the second container  204 . In some instances, each of the first container  204 , offset device  230  and sleeve  228  can be made of metal and can be coupled together by welding, or by mechanical or chemical attachment such as with mechanical fasteners like nuts and bolts, rivets, soldering, adhesives, including epoxies. The second sleeve  228  can be coupled to the second container  204  opposite the first sleeve  228 , and can be aligned with sleeve  222  to accept the companion fork of the waste collection vehicle that can be inserted into sleeve  222  and the second sleeve  228  at a same time. Thus, while sleeves  228  are shown aligned with sleeves  220  and  222 , they could also be aligned with sleeves  216  and  218 , depending on the configuration and design of device  200 . A stand-off distance or offset between the second container  204  and the second sleeve  228  can be determined completely, or in part, by a distance or dimension of the offset device  230 . The stand-off distance can be of any distance, but will advantageously be sufficient to allow for a sleeve, such as sleeve  218  to be disposed between the sleeve  228  and the side surface of the second container  204 . 
     A set of sleeves on the first container  202  and a set of sleeves on the second container  204  can be interlocking or mateably coupled to each other so that the interlocked set of sleeves can facilitate entry of the forks of a waste collection vehicle into the interlocked sleeves at a same time for lifting of the first container  202  and the second container  204  at the same time.  FIGS. 18A-18E  shows a non-limiting example in which sleeves  220  and  222  are formed comprising an opening or open central section. The second pair of sleeves including sleeves  220  and  222  are positioned to be aligned with the third pair of sleeves  228  on the second container  204 . The central area of sleeves  220  and  222  are opened and spaced to enable the third pair of sleeves including sleeves  228  of the second container  204  to be disposed positioned in the openings of sleeves  220  and  222 . The second set of sleeves including sleeves  220  and  222  can serve at least two purposes. First, the second set of sleeves including sleeves  220  and  222  can be used in combination with the third set of sleeves including sleeves  228  to simultaneous lift the two aligned and interlocked containers  202  and  204  by holding the containers  202  and  204  in stationary or fixed position with respect to each other by reducing or eliminating relative movement between the two containers  202  and  204  with respect to one another. Second, the opening in sleeves  220  and  222  can comprise sloped, angled, or ramped edges or surfaces that provide alignment and guidance for the device  200  when placing the first container  202  together with the second container  204 , such as when the first container  202  is positioned with respect to the second container  204  so that a small or minimal gap between the front surface  212  and the rear surface  214  of the first and second containers  202  and  204  exists. In some instances, the gap between the front surface  212  and the rear surface  214  of interlocked containers  202  and  204  can comprise the minimal gap comprising a distance or offset less than or equal to 2 cm, 5 cm, or 10 cm. 
     As shown in  FIGS. 18B-18E , the third pair of sleeves  228  can also be formed with a surface or edge comprising a mirror image, conjugate surface, interlocking surface, or corresponding surface, to the opening in the first or second set of sleeves, such as the opening shown in sleeves  220  and  222 . Accordingly, the surface or edges of the third pair of sleeves including sleeves  228  can also be sloped, angled, or ramped. In some embodiments, the sloped, angled, or ramped surfaces or edges of sleeves  220  and  222  can be formed at complementary angles with sleeves  228  so that sleeves  220  and  222  can be parallel or substantially parallel with sleeves, such as along the openings in the sleeves  220  and  222 . As indicated above, the angled sides edges of the sleeves  220 ,  222 , and  228  can further serve as alignment mechanisms for providing relative alignment between first container  202  and second container  204  to form device  200  when positioning the first container  202  with a minimal gap between the front surface  212  and the rear surface  214  of the first and second containers  202  and  204 , respectively. 
     Similar to the open sections formed in the second set of sleeves comprising sleeve  220  and  222 , the second container  204  can also comprise a third set of sleeves comprising open sections similar to those formed in sleeves  220  and  222  of the first container  202 . The openings in the third set of sleeves, or the sleeves in the second container, can be generally thought of, for ease of conceptualization, in at least two ways. First, the openings in the sleeves of the second container  204  can be thought of as an opening, void, or space within, or along a length of, a single sleeve. Second, and alternatively, the opening can be thought of a space or void that is defined by edges of multiple smaller sleeves that when taken together, form the third set of sleeves. The multiple smaller sleeves could include a first end of one smaller sleeve and a second end of another smaller sleeve. While both conceptual approaches can be helpful, for ease of explanation and for brevity, the following discussion is presented with respect to the later approach, in which two smaller sleeves with two ends defining an opening form each sleeve of a third pair of sleeves. 
     Accordingly,  FIGS. 18D and 18E , for example, disclose a third pair of sleeves comprising smaller sleeves  228  and sleeves  232 , which taken together form front and back edges of the openings into which the second pair of sleeves including sleeves  220  and  222  can be disposed for an interlocking fit. As an example, sleeves  232  are shown spaced apart from, or offset with respect to, the pair of sleeves  228 . The space between sleeves  228  and  232  can enable an interlocking fit or placement of the second pair of sleeves, including sleeves  220  and  222  of the first container  202 , between the third pairs of sleeves, including sleeves  228  and  232 . Accordingly, the sleeves  220 ,  222 ,  228 , and  232  can be aligned in an interlocking position when the dual waste collection device  200  is in its resting position, thereby preventing relative movement between containers  202  and  204  during simultaneous lifting of both the containers  202  and  204 . Consistent with the descriptions given herein, sleeves  228  and  232  can be made of materials similar, or identical, to materials forming the first and second containers  202  and  204 , or sleeves  216 ,  218 ,  220 , or  220 . Similarly, sleeves  228  and  232  can further comprise hollow channeling  233  similar or identical to the hollow channeling described above with respect to sleeves  216 ,  218 ,  220 , and  220 . 
     Dual waste collection device  200  can allow for empting of only the first container  202 , empting of only the second container  204 , and emptying of both the first container  202  and of the second container  204  at a same time. In an instance when both the first container  202  and the second container  204  are lifted at a same time, any waste collected within both containers can be emptied at a same time. Alternatively, if emptying of the contents of only one of the containers is desired, a locking device  234  can be used to secure a lid of one of the containers when both of the containers are being lifted so that the contents of the locked container remain held within the container by the locked lid. As a non-limiting example, the lid  206  of the first container  202  can be locked in place so that when both containers  202  and  204  are lifted together, only the contents of the second container  204  are emptied into the waste collection vehicle. This can allow for emptying of only the second container  204  when placement of the waste collection vehicle forks are disposed within sleeves  218 ,  222 ,  228 , and  232  for simultaneous lifting of both the first container  202  and the second container  204 . Alternatively, the second container  204  can be emptied individually if lifted individually by a fourth set of sleeves fixedly coupled to only the second container  204 , without being aligned with another set of sleeves that also receives the lifting forks of a waste collection vehicle at a same time as the fourth set of sleeves. While the fourth set of sleeves referenced herein includes “fourth” in its name, the fourth set of sleeves could be included on device  200  or any other of the devices included herein, such as devices  300  or  400 , even if there are only a total of three sets of sleeves, or any other number of sleeves. The first container  202  can of course be emptied on its own by lifting only the first container by placing the forks of the waste collection vehicle within the first set of sleeves, or within sleeves  216  and  218 . 
     In some embodiments, the locking mechanism  234  for lid  206  can be formed as a latch  236 . The latch  236  can be hingedly or rotatably coupled to any surface of the first container  202 , such as the front surface  212 . The latch  236  can comprise a hook  238  that can engage the lid  206  to lock the lid  206  when the first container  202  and second container  204  are positioned or coupled together. When the first container  202  and second container  204  are lifted together, the second container  204  can press the latch  236 , rotating it upwards and towards the front surface  212  and lid  206  so that the hook  238  can engage and lock the lid  206 . Thus, the lid  206  can remain closed when both the first container  202  and second container  204  are lifted together. When the forks of a waste collection vehicle pass through the first pair of sleeves including sleeves  216  and  218  to lift just the first container  202  slightly above the second container  204 , the angle of the front surface of the first container can cause the latch  236  to fall forward and away from front surface  212  and lid  206  so that the hook  238  disengages the lid  206 . The movement of the latch  236  away from the front surface  212  can be further enhanced by use of a spring or spring-like member. This unlocks the lid  206 , thereby allowing the lid  206  to open when the first container  202  is emptied. 
     As shown in  FIGS. 18B, 18D, and 18E , the second container  204  can also comprise a pair of support members  240  that can be fixedly or releasably coupled to one or more containers of the device  200 . Support members  240  can prevent relative movement of portions of the device  200  with respect to each other, such as relative movement between the first container  202  and the second container  204 . Reduced relative movement can be advantageous both for when the first and second containers  202  and  204  are being lifted together, or when the containers are at rest together during collection of waste and before emptying of the collected waste. 
     Support members  240  can be made of a material that is similar or identical to the material of the containers  202  and  204 , or any of the sleeves attached thereto. Support members can comprise separate or interconnected pieces of any size and shape, and can comprise a cross-sectional area that is square, rectangular, circular, oval, H-shaped, T-shaped, I-shaped, U-shaped, or any other shape. Support members can be coupled or attached to the containers  202  and  204  by welding, or by mechanical or chemical attachment such as with mechanical fasteners like nuts and bolts, rivets, soldering, adhesives, including epoxies. The first container  202  can be releasably coupled to the support members  240  so that the support members  240  can assist in coupling the first and second containers  202  and  204  together when at rest or when being lifted together. The support members  240  can also be separate from, or not in contact with, the first container  202  when the first container  202  is being lifted and emptied on its own. Depending on the configuration and design of device  200 , the relative and fixed nature of attachment between the first container  202  and the second container  204  could also be reversed. 
     Support members can comprise both straight and angled portions, and can comprise both horizontal and vertical portions or segments. Support members  240  can be fixedly or permanently coupled to a bottom surface of the second container  204 , and extend away from the second container  204  in a substantially horizontal direction to create a space or surface for receiving placement of the first container  202 . The support members  240  can also include a vertical or substantially vertical portion that is angled upwardly away from the horizontal portion and upwardly from a bottom surface of the first and second containers  202  and  204 . In some instances, an angle or radius of curvature between the horizontal and vertical portions of the support members  240  can match or correspond to an angle or radius of curvature of the portion of a container, such as the first container  202 , that is adjacent or in contact with the support members  240 . The vertical or upwardly extending portion of the support members  240  can also comprise a sloped, angled, or ramped portion, such as an end portion. The sloped, angled, or ramped portion of one or more of the support members  240  can further serve as an alignment mechanism for providing relative alignment between first container  202  and second container  204  when positioning the first container  202  with a minimal gap between the front surface  212  and the rear surface  214  of the first and second containers  202  and  204 , respectively. Taken together, the horizontal and vertical components of support members  240  can provide an additional mechanism for aligning the first and second containers  202  and  204  and for preventing relative movement of the two containers  202  and  204  with respect to one another during simultaneous lifting, or rest, of the two containers  202  and  204 . 
     In some embodiments, the dual waste collection device, such as device  200 , can comprise rollers, slides, wheels, balls, or bearings  242  to facilitate relative movement between portions of the device, such as first container  202  and second container  204 . Rollers  242  can be placed at any location on device  200 , including where contact between portions the first container  202  and the second container  204  is possible, or likely, especially when the first and second containers  202  and  204  are moved relative to one another.  FIG. 18C  shows an embodiment in which rollers  242  can be placed on an interior side or surface of one or more sleeves, such as on or adjacent an inner surface of sleeves  218  and  220  of the first container  202 . The rollers  242  can be positioned on the section of the sleeves  218  and  220  that extend away from the first container  202 , through the plane containing front surface  212 . Stated another way, rollers  242  can be placed on an interior side or surface of one or more sleeves that defines a space or area within which the second container  204  can be positioned or placed. As such, the rollers  242  can allow the first container  202  to be more easily lifted away from and realigned with the second container  204  than without the rollers. The use of rollers  242  can also reduce damage, scratching, or chipping of the first container  202  and the second container  204  by reducing contact and impacts between the first container  202  and the second container  204 . 
     In some embodiments, additional rollers, slides, wheels, balls, or bearings  244  are placed on or near a bottom edge of front surface  212  of the first container  202 . The rollers  244  can further allow the first container  202  to be more easily lifted away from, and realigned with, the second container  204 . The rollers  244  can be used with guide rails  246  to properly align the first container  202  with the second containers  204 , such that the sleeves of device  200  are properly aligned with respect to each other. 
       FIGS. 19A-19G  show another embodiment of a dual waste collection device, device  300 . A brief summary of the views shown in each of the  FIGS. 19A-19G  is briefly summarized in this paragraph, after which a more detailed description of each of the  FIGS. 19A-19G  is presented.  FIG. 19A  shows a perspective view of front and left side of device  300 .  FIG. 19B  shows another perspective view of front and left side of the device  300 .  FIG. 19C  shows a perspective view of the rear and left side of device  300 .  FIG. 19D  shows a front perspective view of the device  300  similar to what was shown in  FIG. 19A , but with a first container being individually lifted by the forks of a standard waste collection vehicle.  FIG. 19E  shows a front perspective view of the device  300  similar to the view from  FIG. 19B , but with the first and second containers being lifted together by the forks of a standard waste collection vehicle.  FIG. 19F  shows a perspective view of the front and left side of first container of the device  300 .  FIG. 19G  shows a perspective view of the front and right side of the second container of the device  300 . 
     Accordingly,  FIGS. 19A-19G  show the device  300  comprises a first container  302  and a second container  304 . In device  300 , either first container  302  or second container  304  can house recyclable or non-recyclable material. For convenience of discussion, the first container  302  will be referred to as housing recyclable waste while the second container  304  will be referred to as being used for non-recyclable waste. However, the opposite could also be true. The first container  302  and the second container  304  can be made of materials that are similar or identical to those described above with respect to the first container  202  and the second container  204 , respectively. Similarly, the first container  302  can comprise a lid  306  that can be similar or identical to the lid  206  disclosed above, the lid  306  of course being configured and adapted to match the first container  302  and the opening in the first container  302  covered by the lid  306 . Additionally, the second container  304  can comprise a lid  308  that can be similar or identical to the lid  208  disclosed above, the lid  308  of course being configured and adapted to match the second container  304  and the opening in the second container  304  covered by the lid  308 . 
     In the embodiment shown in  FIGS. 19A-19G , the first container  302  and second container  304  are disposed in a side-by-side or substantially side-by-side arrangement relative a position of a waste collection vehicle ready to empty one or more of the containers of the device  300 . As such, the side-by-side position of the first container  302  and the second container  304  can also be made with reference to the relative position of the sleeves used for receiving the forks  301  of the standard waste collection vehicle so that the front surface  312  of the first container  302  and the front surface  314  of the second container  304  are approximately flush, or contained within a same plane, when the containers are in their resting position, or are being lifted together without relative movement between one another. 
     The first container  302  can comprise a first pair of sleeves for lifting the first container  302  that includes sleeve  316  that is formed as a left sleeve at a left side of the first container  302  and sleeve  318  that is formed as a right sleeve at a right side of the first container  302 . The first pair of sleeves comprising  316  and  318  can be made of materials that are the same or similar to the materials of sleeves  216 ,  218 , first container  202  and second container  204 . Sleeves  316  and  318  can be joined or coupled to the first container  302  in a same or similar manner as to how sleeves  216  and  218  can be coupled to the first container  202 . The first pair of sleeves including sleeves  316  and  318  can be used to lift the first container  302  individually. Sleeve  316  and  318  can be aligned parallel or substantially parallel to each other, so that forks  301  of a standard waste collection vehicle comprising a fixed position and width can be inserted into sleeves  316  and  318  for lifting and emptying the first container  302 . The sleeve  316  can comprise a hollow channeling  317  and sleeve  318  can comprise a hollow channeling  319 . Hollow channeling  317  and  319  can be similar or identical to hollow channeling  217  and  218  as described above. 
     Sleeve  316  can be coupled to a side surface of the first container  302 , and in some instances is directly attached to the left side surface of the first container  302 . Sleeve  316  can extend horizontally along a left side of the side surface of the first container between front and back surfaces of the first container  302 . Sleeve  316  can be parallel or substantially parallel with the left side of the first container  302 , or can comprise a relative angle that is within plus or minus a measure that is less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more of the left side of the first container. Sleeve  316  can be positioned to accept a fork  301  of a front load waste collection vehicle when the pair of forks  301  is in a first position and aligned with sleeves  316  and  318  to lift the first container  302  individually. Sleeve  318  can be offset away from the left side of the first container  302  opposite right side of the first container  302  to which sleeve  316  is coupled, and oriented towards. A position or offset of sleeve  318  away from the first container  302  and oriented towards a left side of the first container  302  can be maintained by one or arms  320 . Sleeve  318  can extend horizontally along, and offset from, a right side of the side surface of the first container between planes containing the front and back surfaces of the first container  302 . Sleeve  318  can be parallel or substantially parallel with the right side of the first container  302 , or can comprise a relative angle that is within plus or minus a measure that is less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more of the right side of the first container. The sleeve  318  can be positioned so as to accept one of the forks  301  when the pair of forks  301  are placed in the first position in alignment with sleeves  316  and  318  to lift the first container  302  individually. 
     Arm  320  can be formed, positioned, and attached to the first container  302  so as to create an opening for the second container  304  within a space or opening created by the arm  320  and adjacent the first container  302  when the first container  302  and second container  304  are in side-by-side resting positions. Arm  320  can also be formed so that it positions sleeve  318  to the far side, or right of the right side, of the second container  304 . Additionally, arm  320  can be formed and positioned to align the first container  302  with respect to the second container  304 , and can also prevent relative side-to-side movement of the containers with respect to each other. A size, shape, cross-sectional area, strength and number of arms  320  can vary according to the configuration and design of device  300 , including anticipated loads. Examples configurations presented with respect to support members  240  are equally applicable with respect to arms  320 . As such, an angle, curve, or radius of arm  320  connecting side portions of the arm  320  disposed adjacent side surfaces of the device  300  to a front portion of arm  320  disposed adjacent front surfaces  312  and  314  can match an angle, curve, or radius of the containers  302  and  304  transitioning between the front surfaces to side surfaces of the containers  302  and  304 . 
     The device  300  can also comprise a second pair of sleeves comprising sleeves  322  and  324 . The second pair of sleeves comprising sleeves  322  and  324  can be made of materials that are similar or identical to those of the first and second containers  302  and  304 . Sleeve  322  and  324  can be coupled, or directly attached to, outer opposing surfaces of device  300  such as with sleeve  322  coupled to a right outer side surface of second container  304 , and with sleeve  324  coupled to a left outer side surface of first container  302 . While sleeves  322  and  324  are shown disposed below or lower than sleeves  318  and  316 , respectively, in alternate embodiments, sleeves  322  and  324  can also be included above sleeves  318  and  316 . Sleeves  322  and  324  can be aligned parallel or substantially parallel to each other, or can comprise a relative angle that is within plus or minus a measure less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more from each other. Similarly, sleeves  322  and  324  can be parallel or substantially parallel the side surfaces of container  302  and  304  to which they are coupled, or can comprise a relative angle that is within plus or minus a measure less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more from each other. The sleeve  322  can comprise a hollow channeling  323  and sleeve  324  can comprise a hollow channeling  325  that allows for the forks of a standard waste collection vehicle to be inserted through the pair of sleeves  322  and  324  to lift the first container  302  and second container  304  together. Hollow channeling  323  and  325  can be similar or identical to hollow channeling  317  and  319 . 
     Sleeve  322  can be attached to a side surface of the second container  304  and be positioned to accept a fork of a front load waste collection vehicle when the pair of forks are placed in a second position to lift the first container  302  and second container  304  together. Sleeve  324  can be coupled to and offset with respect to the second container  304  by being coupled or directly attached to one or more arms or supports  326 . A first side of arms  326  can be coupled to a bottom surface of the second container  304  and extend away from the second container  304  a distance greater than or equal to width of the first container  302  such that a second end of arms  326  opposite the first end of arms  326  can be disposed adjacent sleeves  316  and adjacent a left side of the first container  302 . Arms  326  can comprise one or more materials of a number, size, shape, position, and cross-sectional area similar to arm  320  and support members  240 . 
     For ease of illustration, a pair of arms  326  is shown formed in the shape of rails, the arms  326  comprising a horizontal section disposed below bottom surfaces of first container  302  and second container  304 , as well as a vertical section comprising a relative angle of approximately 90 degrees with respect to the horizontal section, although any other angle could be used, such as angle that is within plus or minus a measure less than or equal to 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or more from each other. A shape, contour, or both of arms  326  can also follow or mirror a shape, contour, or both of the first and second containers  302  and  304 . The arms  326  can extend and position the sleeve  324  to be aligned with sleeve  328  of the first container  302  and to accept the companion fork when the pair of forks  301  are in a second position, different from the first position, and in-line with sleeves  322  and  324  to lift the first container  302  and the second container  304  together. 
     In an embodiment, the arms  326  can be attached to the bottom surface of the second container  304  and run under the first container  302  and up the far side of container  302 . The sleeve  324  can be attached to the end of the vertical section of arm  326 . Sleeve  324  can be aligned with sleeve  322  and positioned such to accept the companion fork of the pair of forks when the forks are placed in a second position to lift the first container  302  and second container  304  together. Arms  326  can comprise any suitable form of attachment to the second container  304 , such as by welding, or by mechanical or chemical attachment such as with mechanical fasteners like nuts and bolts, rivets, soldering, adhesives, including epoxies. As a non-limiting example, the arms  326  can be attached to the side of the second container  304  and follow the same shape of arm  320  along the front of containers  302  and  304  but be positioned below arm  320  and achieve the same function. 
     The second pair of sleeves, including sleeves  316  and  318 , can comprise a third pair of sleeves, comprising sleeves  328 , that are coupled or directly attached to a bottom surface of sleeves  316  and  318 , respectively. Sleeves  328  can be formed to comprise an open central section that is similar or identical to the open central area described above with respect to device  200 . Thus, below each sleeve  316  and  318  can be a sleeve  328  comprising a central area below sleeve  316  and  318  that is open. The pair of sleeves  324  can be in alignment with the second pair of sleeves  322  and  324  on the second container  304 . The central area of sleeve  328  can opened and spaced to enable the second pair of sleeves  322  and  324  of the second container  304  to be disposed within the opening. The sleeve  328  can serve at least two purposes. First, sleeve  328  can be used in combination with sleeves  322  and  324  to simultaneous lift the two containers  302  and  304  without, or with minimal, relative movement of the two containers  302  and  304  with respect to one another. Second, the opening in sleeves  328  can also be used as an alignment device when placing the first container  302  back in position so that the front surface  312  of the first container  302  and the front surface  314  of the second container  304  are approximately flush. 
     The second pair of sleeves  322  and  324 , like the openings described above, can be formed to comprise angled side edges. Sleeves  328  also comprise angled side edges so that the side edges of sleeves  322  and  324  run approximately parallel with the side edges of sleeves  328 . The angled side edges of the sleeves  322 ,  324  and  328  can further serve as alignment mechanisms for placing the first container  302  back in position so that the front surface  312  of the first container  302  and the front surface  314  of the second container  304  are approximately flush. In this regard, device  300  is similar to device  200 , and the discussion included above with respect to device  200  is applicable here. 
     To accommodate simultaneous lifting of the two containers  302  and  304 , device  300  can also include a locking device  330  to secure the lid  306  of the first container  302 . This can allow the emptying of only second container  304  when simultaneous lifting of the two containers  302  and  304  for emptying. The first container  302  can still be lifted and emptied individually like in the previous embodiment. 
     In the present embodiment, the locking mechanism  330  for lid  306  can include a bar  332 . The lid lock bar  332  can be rotatably or hingedly coupled to the front surface  312  of the first container  302 . When the first container  302  is at rest or when the forks  301  of a standard waste collection vehicle are in a first position and inserted into hollow openings  317  and  319  of the pair of sleeves  316  and  318  to lift just the first container  302  individually, the lock bar can be disengaged and rotated away from the lid  306 . This rotation allows for the lid  306  to be lifted to place waste (either recyclable or non-recyclable, as designated for use) inside and also allows for the lid to open when emptying just the first container  302  individually. 
     When the forks of a standard waste collection vehicle are in a second position and inserted into hollow openings  323 ,  325 , and  329  of the pair of sleeves  322  and  324  and pair of sleeves  328  to lift the first container  302  and second container  304  together, the lid lock bar  332  engages and secures the lid  306  and prevents lid  306  from opening. The lid lock bar  332  can be made to rotate towards the front surface  312  of the first container  302  and secure lid  306  by the forks engaging an actuating mechanism  334  and linkage  336 . The lock bar  332  can also disengage the lid  306  and return to its open position when the forks of the waste collection vehicle are retracted from the sleeves by means of a spring or spring-like member  338 . In some embodiments, member  338  is a torsional spring hinge that couples the actuating mechanism  334  to the front surface  312  of the first container  302 . 
     In some embodiments, the actuating mechanism  334  can be a bar that is moveably or hingedly coupled to the front surface  312  of the first container  302 . The linkage  336  can be any of a rod, belt, cable, chain, or similar device for transferring motion. 
     In some embodiments, wheels  340 , similar to wheels  242 , can be placed on the interior side of arms  326  on the second container  304 . The wheels  340  can be positioned on the vertical section of arms  326 . The wheels  340  can be used to allow the first container  302  to more easily be lifted away from and realigned with the second container  304 . The wheels  340  can be used with guide rails  342  to properly align the first and second containers  302  and  304  respectively. The discussion from above relative to wheels  242  and device  200  is also applicable here, and applies equally to wheels  340  and device  300 . 
     The first container  302 , second container  304 , or both, can also comprise feet  344  attached to, or extending below, the bottom surfaces of the first and second containers  302  and  304 . Feet  344  can adjust or determine a placement of the first container  302  upon during its resting position. The feet  344  can also raise the containers  302  and  304  off of the ground, provide room for arms  326 , and level the first container  302  and second container  304  relative to each other. 
     As shown, e.g., in  FIG. 19C , adjacent side walls of first and second containers  302  and  304  disposed at an interior or middle portion of device  300  can comprise interlocking sidewalls as shown in  FIG. 19C . Interlocking sidewalls will allow first container  302  to be lifted without contacting second container  304 , and a lip or ledge that will prevent second container  304  from being lifted without contacting first container  302 . Alternatively, the first and second containers  302  and  304  can comprise substantially planar sidewalls without a lip or ledge on adjacent side walls at an interior or middle portion of device  300  that will allow either the first or second containers  302  and  304  to be lifted without contacting the other. 
       FIGS. 20A-20E  show another embodiment of dual waste collection device shown as device  400 . As in the previous embodiments, the device  400  comprises a first container  402  and a second container  404 . A brief summary of the views shown in each of the  FIGS. 20A-20E  is briefly summarized in this paragraph, after which a more detailed description of the features shown in each of the  FIGS. 20A-20E  is presented.  FIG. 20A  shows a perspective view of a front and left sides of the device  400 .  FIG. 20B  shows a perspective view of a rear and right surface of the device  400 .  FIG. 20C  shows a perspective view of the front and left of the device  400  with the additional detail of the first container  402  being lifted individually by the forks of a standard waste collection vehicle from the second container  404 .  FIG. 20D  shows a perspective view of the front and left sides of the first container  402  without the second device  404  and a detail view A of a lid locking mechanism.  FIG. 20E  shows a perspective view of front and left sides of the second container  404  without the first container  402 . 
     In this embodiment, either container  402  or  404  can house recyclables or non-recyclables. For further discussion, the first container  402  is used for recyclable waste collection and the second container  404  is used for non-recyclable waste collection. The first container  402  and second container  404  can be made of any suitable material, including materials that are the same or similar to those discussed above with respect to device  200 , including the first container  202  and the second container  204 . 
     In the embodiment shown in  FIGS. 20A-20E , the majority of the volume and weight of the first container  402  is placed on top of the second container  404  when the two containers are in a resting position and while the first container  402  and second container  404  are lifted together. 
     The first container  402  and second container  404  can comprise lids  406  and  408 , respectively. Lids  406  and  408  can be similar or identical to lids  206 ,  208 ,  306 , and  308 , and the previous discussion of lids is applicable here. Side doors  410  can also be formed on the first container  402  and second container  404 , respectively. Side doors  410  can be similar or identical to side doors  210 , and the previous discussion of side doors is applicable here. In some embodiments, doors  410  formed in the first container  402 . In other embodiments, side doors  410  can also be formed on the second container  404  in addition to, or in place of, side doors  402  on the first container. 
     In some embodiments, the first container  402  can comprise a bottom surface with a flat, central section  412  (see, e.g.,  FIG. 20D ) and angled exterior sections  414  (see, e.g.,  FIG. 20D ). The second container  404  can comprise a top surface with a flat, central section  416  (see, e.g.,  FIG. 20E ) and angled exterior sections  418  (see, e.g.,  FIG. 20E ). The bottom surface sections  412  and  414  of the first container  402  and the top surface sections  416  and  418  of the second container  404  can be formed such that surface  412  mates to surface  416  and surfaces  414  mate to surfaces  418  when the first container  402  is at rest on top of the second container  404 . While the particular angles and portion of the first and second containers  402  and  404  can vary according to the needs, configuration, and design of the device  400 , the specific configuration selected can comprising a matching, mirror image, or conjugate contour or surface that is mateable or interlocking between the first container  402  and the second container  404 . 
     Advantageously, the angle of the bottom exterior surfaces  414  and the top exterior surfaces  418  can be selected to make it easier to better align the first and second containers  402  and  404  so that there is approximately equal gap between the side surfaces of the first container  402  and the second container  404 . The angle of the bottom exterior surfaces  414  and the top exterior surfaces  418  further keeps the first container  402  from moving side to side relative to the second container  404  when the containers are at rest. 
     In some embodiments, the first container  402  can comprise an angled, central front surface  420  (see, e.g.,  FIG. 20D ) and the second container  404  can comprise an angled, central rear surface  422  (see, e.g.,  FIG. 20E ). The central front surface  420  and the central rear surface  422  can be parallel or substantially parallel to one another. The angle of the central front surface  420  and the rear surface  422  can be in a range of 0-60° from vertical, 5-40° from vertical, 10-20° from vertical, 5-20° from vertical, 5-15° from vertical, or similar suitable range that can allow the first container  402  to more easily be raised and lifted away from the second container  404 . The angle of the central front surface  420  and the central rear surface  422  can also facilitate and make easier an align between the first and second containers  402  and  404 , respectively, which in turn can provide a small or a minimal gap between the central front surface  420  and the central rear surface  422  of the first and second containers  402  and  404 . In some instances, a distance of the gap can be minimized or can be in a range less than or equal to 1-30 cm, 1-20 cm, 1-10 cm, or other similarly suitable range. 
     The first container  402  can comprise a pair of sleeves  424 . Sleeves of device  400 , including the pair of sleeves  424  can be made of a material that is the same or similar to the material of the first and second containers  402  and  404 . Sleeves of device  400 , like sleeves  424  and the other sleeves discussed herein, can be coupled to device  400 , including first and second containers  402  and  404  by welding, or by mechanical or chemical attachment such as with mechanical fasteners like nuts and bolts, rivets, soldering, adhesives, including epoxies. An individual sleeve of the pair of sleeve members  424  can be attached to each side section of the first container  402 , or to a left side surface and an opposing right surface. All the sleeves of device  400 , including pair of sleeves  424 , can comprise a hollow channeling  426 . Hollow channeling  426 , and the other hollow channeling of device  400  can be the same or similar to hollow tubing  217  discussed above with respect to device  200 , and the same discussion is applicable here with respect to device  400 . The hollow channeling  426  can allow a standard fork lift-operated waste collection vehicle to insert its fork through the pair of sleeves  424  to raise and empty the first container  402  by itself. 
     An end cap  425  (see, e.g.,  FIG. 20B ) can be placed at the end of each sleeve  424 . The end caps prevent the first container  402  from sliding down the forks as it is being emptied. Without this feature, the first container  402  could slide down the forks as it was lifted and emptied if the forks of the waste collection vehicle are not fully inserted into sleeves  424 . As the first container  402  was lowered back into position on top of the second container  404 , there could be insufficient space to properly position the first container  402  with respect to the second container  404 . 
     The second container  404  can comprise a pair of sleeves  428 . An individual sleeve of the pair of sleeve members  428  can be attached to each side section, or to opposing left and right side sections, of the second container  404  and below the pair of sleeves  424  on the first container  402 . The pair of sleeves  428  can comprise a hollow channeling  430  (see, e.g.,  FIG. 20E ). 
     Each sleeve  424  can comprise another sleeve  432  coupled to the underside of the sleeve  424 . Each sleeve  432  can also comprise a hollow channeling  434 . 
     Sleeve  432  can be formed to comprise an open central section, similar to the other sleeves discussed above that comprise open central sections, and as such, the discussion from above is applicable with respect to device  400 . Thus, below each end of the sleeve  424  can be the sleeve  432  with the central area below sleeve  424  open. The pair of sleeves  432  can be in alignment with the second pair of sleeves  428  on the second container  404 . The central area of sleeve  432  can be open and spaced to enable the pair of sleeves  428  of the second container  404  in between the opening. The sleeve  432  can serve at least two purposes. First, sleeve  432  can be used in combination with sleeves  428  to simultaneous lift the two containers  402  and  404  without movement of the two containers  402  and  404  with respect to one another. Second, the openings in sleeves  432  can be used as an alignment device when placing the first container  402  back in position so that there is a minimal gap between the central front surface  420  and the central rear surface  422  of the first and second containers  402  and  404 . 
     The second pair of sleeves  428  can be formed to comprise angled side edges  436 . The discussion of angled sides from above is also applicable here. Sleeves  432  can comprise angled side edges  438  so that the side edges  436  of sleeves  428  run approximately parallel with the side edges  438  of sleeves  432 . The angled sides edges  436  and  438  can further serve as alignment mechanisms for placing the first container  402  back in position so that there is a small or minimal gap between the central front surface  420  and the central rear surface  422  of the first and second containers  402  and  404 . As used herein, small or minimal gap comprises gaps with a distance less than or equal to 15 cm, 10 cm, 5 cm or other similarly suitable distance. Similarly, a distance of the gap can be minimized or can be in a range of 1-30 cm, 1-20 cm, 1-10 cm, or other similarly suitable range. 
     Because device  400  enables simultaneous lifting of the two containers  402  and  404 , device  400  can also include a locking device  440  to secure the lid  406  of the first container  402 . This can allow the emptying of only second container  404  when simultaneous lifting of the two containers  402  and  404  for emptying. The first container  402  can still be lifted and emptied individually like in the previous embodiment. The discussion of securing a lid and emptying a first, second, or both the first and second container discussed above is also applicable here with respect to the first container  402  and the second container  404  of device  400 . 
     In some embodiments, the locking mechanism  440  for lid  406  can be a latch  442  (see, e.g.,  FIG. 20D , Detail A). The latch  442  can be rotatably or hingedly coupled to the front surface  420  of the first container  402 . The latch  442  can comprise a hook  444  that can engage the lid  406  to lock the lid  406  when the first container  402  and second container  404  are positioned together. When the first container  402  and the second container  404  are lifted together, the second container  404  can press the latch  442  rotating it upwards and towards the front surface  420  and lid  406  so that the hook  444  can engage and lock the lid  406 . Thus, the lid  406  can remain closed when both the first container  402  and second container  404  are lifted together. When the forks of a standard dump truck pass through the pair of sleeves  424  to lift just the first container  402  slightly above the second container  404 , the angle of the front surface of the first container can cause the latch  442  to fall forward and away from front surface  420  and lid  406  so that the hook disengages the lid  406 . The movement of the latch  442  away from the front surface  420  can be further enhanced by use of a spring or spring-like member  446  (see, e.g.,  FIG. 20D , Detail A). In the current embodiment, the spring member can be a hub comprising an internal torsional spring that can unlock the lid  406 , thereby allowing the lid  406  to open when the first container  402  is emptied. 
     In some embodiments, rollers  448 , can be placed on or near the bottom edge of the central front surface  420  of the first container  402 . The rollers  448  are used to allow the first container  402  to more easily be lifted away from and realigned with the second container  404 . Rollers  448  can be similar or identical to rollers or wheels  242  and  244 , and as such the discussion relative to rollers or wheels  242  and  244  is applicable here with respect to device  400 . 
       FIGS. 21A-21D  show another embodiment of a dual waste collection device shown as device  500 . As disclosed with respect to device  500 , a dual waste collection device can comprise a single container comprising a first compartment  502  and a second compartment  504 . A brief summary of the views shown in each of the  FIGS. 21A-21D  is briefly summarized in this paragraph, after which a more detailed description of each of the  FIGS. 21A-21D  is presented.  FIG. 21A  shows a perspective view of front and left sides of the device  500 .  FIG. 21B  shows another perspective view of front and right side views of the device  500  with lids open to reveal first compartment  502  and the second compartments  504  together with a partitioning wall  510  that divides the first and second compartment walls  502  and  504 , respectively.  FIG. 21C  shows another perspective view of front and left sides of the device  500  similar to that shown in  FIG. 21A , but with a locking mechanism securing a lid of the first compartment  502  disengaged by the forks of a standard waste collection vehicle in a first position and with a lid open.  FIG. 21D  shows another perspective view of front and right sides of the device  500  with a locking mechanism securing a lid of the second compartment  504  disengaged by the forks of a standard waste collection vehicle in a second position and with a lid open and forks being disposed within sleeves of the device  500 . 
     The device  500  can comprise two or more compartments, and as such can comprise compartments in addition to the first compartment  502  and the second compartment  504 . Compartments  502  and  504  can be made of materials that are the same or similar to the materials used for containers  202  and  204 , such that the discussion of materials from above is applicable here with respect to compartments  502 ,  504 , and partitioning wall  510 , discussed below. However, for ease of discussion, the embodiment illustrated with respect to device  500  comprises just two compartments. Each compartment can comprise a lid, and as shown in the figures, the first compartment  502  can comprise a lid  506  and the second compartment  504  can comprise a lid  508 . Lids  506  and  508  can be similar or identical to lids  206  and  208  discussed above, and as such that discussion is applicable here, with respect to device  500 . 
     Each compartment of the device  500  can comprise at least one partitioning wall  510  disposed between the compartment and each adjacent compartment.  FIGS. 21B-21D  show the partitioning wall  510  separating the first compartment  502  and second compartment  504 . 
     Each compartment  502  and  504  can comprise a door for receiving either recyclable waste or non-recyclable waste inside a corresponding compartment. As such, the first compartment  502  can comprise a door  512  and the second compartment  504  can comprise a door  514 . Doors  512  and  514  can be similar or identical to doors  210  discussed above, and as such that discussion is applicable here, with respect to device  500 . 
     The device  500  can comprise number of sleeves, including a first pair of sleeves  516 . All of the sleeves of device  500 , including the first pair of sleeves  516 , can be made of materials that are the same or similar to the first and second compartments  502  and  504  or the same as sleeves  216  and  218  from device  200 , and can be formed and coupled to other elements in the same ways. An individual sleeve of the pair of sleeve members  516  can be attached to each side section of the device  500 , or to opposing left and right sides. The first pair of sleeves  516  can comprise hollow channeling  518 . The hollow channeling can be the same or similar to hollow channeling  217  or  219  from device  200 , and the same discussion from above is applicable here with respect to all sleeves of device  200 , including the first pair of sleeves  516 . The hollow channeling  518  can allow for, among other things, a standard fork lift-operated waste collection vehicle to insert a fork through the pair of sleeves  516  to raise the device  500  and empty the first compartment  502 . 
     The device  500  can comprise a second pair of sleeves  520 . The second pair of sleeves  520  can be made out of the same material as the side walls of device  500 . An individual sleeve of the second pair of sleeve members  520  can be attached to each side section, or opposing left and right side walls, of the device  500  and can be positioned above or below the first pair of sleeves  516 . Alternatively, and as can be true all embodiments comprising pairs of sleeves stacked in a top-and-bottom configuration, the second pair of sleeves  520  can be coupled to the left or right of the first pair of sleeves  516  as discussed in greater detail above. The pair of sleeves  520  can also comprise a hollow channeling  522 . The hollow channeling  522  can allow for a standard fork lift-operated waste collection vehicle to insert its forks through the pair of sleeves  520  to raise the device  500  and empty the second compartment  504 . 
     Because an entirety of the device  500  is lifted each time one or more of the compartments within the device  500  is emptied, the device  500  can also include one or more locking mechanisms to secure the lid to each respective compartment. This can allow the emptying of only one compartment when lifting the device  500 . In some embodiments, a locking mechanism  524  can secures the lid  506  of the first compartment  502  and prevents it from opening when emptying just the second compartment  504 . A locking mechanism  526  can likewise secure the lid  508  of the second compartment  504  and prevent it from opening when emptying just the first compartment  502 . The discussion above regarding the locking mechanisms of other embodiments is also applicable to the discussion of device  500 . 
     In some embodiments, each locking mechanism can engage hook members  528  protruding from the front edge of each lid, securing each lid individually and preventing it from opening when emptying another compartment. When lid locking mechanism  524  engages the hook members  528  of lid  506 , the lid  506  can be secured and kept from opening when the device  500  is lifted to empty the second compartment  504 . When lid locking mechanism  526  engages the hook members  528  of lid  508 , the lid  508  can be secured and kept from opening when the device  500  is lifted to empty the first compartment  502 . 
     In some embodiments, the locking mechanism  524  can comprise one or more hinged members  532  that are coupled to a top area of the front surface  530  of the device  500 . At one end of locking mechanism  524 , a hinge member or members  532  can be connected to a locking bar  534  that is positioned near the top of the device  500  by a linkage  536 . When device  500  is in a resting position without the forks of a waste collection vehicle inserted into sleeves  516 , the locking mechanism  524  can be in a first, locked position. In a first position, the locking bar  534  can engage the hook members  528  of lid  506 , which secures lid  506  and prevents it from opening. 
     Attached to a second end of the locking mechanism  524  can be one or more actuating plates  538  that can be connected by a linkage  540 , such as a rod, chain, belt, or other suitable device. The actuating plate  538  can be positioned in front of one or both individual sleeve members of the pair of sleeves  516 . When the forks of a waste collection vehicle are inserted into sleeves  516 , the locking mechanism  524  can be in a second, unlocked position. In a second position, the forks of a waste collection vehicle can push the actuating plat  538 , rotating it upwards. The rotation of plate  538  can pull the linkage  540 , which can in turn pull the locking bar  534  open, allowing the hook members  528  of lid  506  to disengage and the lid to open. 
     In some embodiments, the locking mechanism  526  can comprise one or more hinged members  542  coupled to a top area of the front surface  530  of the device  500 . At one end of locking mechanism  526 , a hinge member or members  542  can be connected to a locking bar  544  that is positioned near the top of the device  500  by a linkage  546 . When device  500  is in a resting position without the forks of a waste collection vehicle inserted into sleeves  520 , the locking mechanism  526  is in a first, locked position. In the first position, the locking bar  544  can engage the hook members  528  of lid  508  to secure lid  508  and prevent the lid from opening. 
     Coupled or attached to a second end of the locking mechanism  526  can be an actuating plate  548  that can be further coupled or connected by a linkage  550 , such as a rod, chain, belt, or other suitable device. The actuating plate  548  can be positioned in front of one or both individual sleeve members of the pair of sleeves  520 . When the forks of a waste collection vehicle are inserted into sleeves  520 , the locking mechanism  526  can be in a second, unlocked position. In the second position, the forks of the waste collection vehicle can push the actuating plate  548 , rotating it upwards. The rotation of the plate  548  can pulls the linkage  550 , which in turn, pulls the locking bar  544  open, allowing the hook members  528  of lid  508  to disengage and the lid to open. 
     While various features including plates, linkages, locking mechanisms, locking bars, and hinge mechanisms have been discussed specifically with regards to device  500 , this description is also applicable to all the other devices disclosed herein. Similarly, the features used for, and discussed in relation to, securing lids in other embodiments and devices is also applicable to device  500 . In other embodiments, other recognized mechanical or electromechanical structures and devices can be used in securing lids of the dual waste collection device to accomplish the desired accessibility of recyclable and non-recyclable waste within the dual waste collection device. 
     While embodiments of the disclosure have been described in terms of various specific embodiments, those skilled in the art will recognize that the embodiments of the disclosure can be practiced with modifications within the spirit and scope of the claims.
