     The waste management receptacle system  1  the embodiments depicted in  FIGS.  1 - 3    of the present invention generally includes a first receptacle  10  comprising a base  14 , sidewalls  5 ,  6 ,  7 ,  8  extending vertically therefrom forming an open-topped structure having an interior portion  15 . A lid  12 , which may be of a similar size and configuration to base  14 , encapsulates interior portion  15 , and may be removable from the primary receptacle or of a hinged configuration such that a pivot point is formed relative to rim  18  of a sidewall  5 ,  6 ,  7 ,  8  for opening and closing the primary receptacle. Within interior portion  15 , a secondary receptacle  20  is disposed, and may be integral with the one or more sidewalls  5 ,  6 ,  7 ,  8  forming interior portion  15 . In the alternative, secondary receptacle  20  may comprise a clamping member  30 , which may be of a U-shaped configuration as depicted, though other similar configurations are not meant to be precluded. While the secondary receptacle  20  depicted in  FIG.  3    comprises a sloped bottom configuration, other geometric configurations of the secondary receptacle bottom, including those having a substantially flat or contoured construction are not meant to be precluded, and the present invention would embrace any geometric configuration which would be suitable to contain particularly odorous waste within an interior receptacle portion. The sloped bottom  24  of the secondary receptacle  20  advantageously facilitates the release of refuse placed within the primary receptacle  10  after inversion during waste management removal operations. Upstanding sidewalls  26   a - c  are integral with sloped bottom, with sidewall  26   a  extending along longitudinal axis L a distance less than sidewall  26   b , resulting in the acute angle of sloped bottom  24 . Sidewalk  26   c  extend from bottom  24 , forming the open-topped secondary receptacle  20 . Secured to rim  28  of the secondary receptacles, preferably via a hinge secured to a sidewall  26   a - c  is lid portion  22 . Lid portion  22  may rotate, translate, or otherwise move between open and closed positions to allow placement of excrement, feces, or other waste within secondary interior  25 . Advantageously, placement of such particularly foul materials within secondary interior  25  prevents fouling of primary receptacle  10  responsive to compression forces applied by additional waste within the interior of primary receptacle  10 . 
     Primary receptacle  10  and secondary receptacle  20  may be constructed of a polymer, fiberglass, or some other material which would provide sufficient durability and flexibility to the receptacles while also achieving a light-weight construction. In some embodiments, primary receptacle  10  may comprise a handle  13  on an upper sidewall surface and wheels on a lower sidewall surface to facilitate transport of the waste management receptacle system  1 . 
     While the secondary receptacle of the embodiments depicted herein is disposed. within only a portion of the primary receptacle, in some embodiments, upstanding sidewalls  26  of the secondary receptacle may extend such that the secondary receptacle would have a dimensional height similar to that of the primary receptacle interior portion  15  (See  FIG.  16   ). 
     Clamping member  30  may be directly coupled to the secondary receptacle  20 , preferably via the upper region of sidewall  26   b  such that lateral member  30   c  of clamping member is adjacent secondary receptacle rim  28 . Longitudinal members  30   a ,  30   b  extend perpendicularly from ends of the lateral member  30   c , forming a U-shaped connecting member which may be received by one or more sidewalls  5 ,  6 ,  7 ,  8  of the primary receptacle  10  via the clamping channel  39 . To further facilitate the attachment of the clamping member to the primary receptacle, the interior portions of the longitudinal member and/or lateral members forming clamping channel  39  may comprise a textured silicone, rubber, or other material to provide additional grip to facilitate the connection between clamping member  30  and the primary receptacle  10 . After received on the sidewall  5 ,  6 ,  7 ,  8 , longitudinal member  30   a  is located on the interior portion  15  of the sidewall, with longitudinal member  30   b  disposed on the exterior surface of sidewall  5 ,  6 ,  7 ,  8 . Clamping member  30  may be constructed of fiberglass, polymers, metals, or metallic alloys including steel, aluminum alloys, or combinations thereof. 
     Clamping member  30  may be secured to the primary receptacle  10  through at least one fastening member  32 , which may be a threaded screw, locking pin, or other similar fastening device. Optionally, the sidewall  5 ,  6 ,  7 ,  8  may comprise one or more openings  19  in order to secure fastening member  32  therein. Responsive to rotation, translation, or other movement of the fastening member(s)  32 , the fastening member  32  will move from a disengaged position where the fastening member(s) are located on the outer portion of the clamping member  30  to an engaged position such that the fastener member is located on the interior portion of the clamping member, i.e., between longitudinal members  30   a  and  30   b . While fastening members are in the disengaged position and after clamping member  30  has been received by a primary receptacle sidewall, the fastening member  32  may be moved to the engaged position, wherein a clamping force may be applied, securing the clamping member  30  to the primary receptacle sidewall. While clamping member  30  is depicted in  FIGS.  2 - 5    as securing the secondary receptacle to a single sidewall of the primary receptacle, the present invention is not meant to be so limited, and other attachment configurations are not meant to be precluded. In some embodiments, like those depicted in the exemplary views of  FIGS.  14  and  15   , the secondary receptacle can be seen adjacent multiple sidewalk of the primary receptacle, and additionally may include a plurality of clamping members for securing the secondary receptacle to the primary receptacle. Further, while contact force is described to secure the clamping member to the primary receptacle, other modalities are not meant to be precluded, such as the use of applying field forces via a magnetic attractive force between the clamping member and the primary receptacle. In one or more embodiments, clamping member may be secured to the primary receptacle by way of adhesive, plastic welding, or any other material which would be known in the art to provide a chemical fastening between the clamping member and the primary receptacle. 
     In one or more embodiments, secondary receptacle may be formed integral with the primary receptacle, thereby removing the need to secure the secondary receptacle to the primary receptacle via clamping member  30 , like the embodiment depicted in  FIG.  16   . In such embodiments, the secondary receptacle and primary receptacle may be injection molded simultaneously, or heat welded, spin welded, adhered, or otherwise to attached. secondary receptacle  20 ′ to the interior of the primary receptacle  10 ′. In such embodiments, the primary lid  12 ′ includes a lid cutout portion  22 ′ secured to the secondary receptacle  20 ′ via a hinge member such that access to the secondary receptacle  20 ′ may be separate to the primary receptacle  10 ′. In some embodiment, lid cutout portion  22 ′ may include a spring-loaded hinge such that use of access latch mechanism  23 ′ on the exterior of the primary receptacle  10 ′ will effect movement of the lid cutout portion  22 ′, primary lid portion  12 ′, or both from the closed position to the open position such that an end user can access the interior of the primary and/or secondary receptacles. 
     In one or more embodiments, the primary receptacle  10  may further comprise one or more stanchion members  33  on sidewall  5 ,  6 ,  7 ,  8  to provide further support or structure to the primary receptacle  10 , preventing collapse of sidewall  5 ,  6 ,  7 ,  8  in situations where fastening member  32  in the engaged position would cause flexing of longitudinal members  30   a ,  30   b  towards one another, and may further prevent damage to the sidewalls of the primary receptacle. Optionally, the primary receptacle  10  may include a peripheral flange extension  18 ′, which would provide strength to the primary receptacle  10 , as well as a stop surface to the fastening member upon inversion of the waste management receptacle system  1 . Advantageously, movement of clamping member  30  would be prevented upon inversion of the waste management receptacle system in the case that the clamping force applied by the fastening member  32  fails. 
     During use of the waste management receptacle system  1 , a user with particularly odorous or foul waste (such as fecal waste) can lift lid  12 , exposing the interior portion  15  of the primary receptacle  10 , as well as secondary receptacle  20  which is encapsulated by secondary lid  22 . The user may then move secondary lid  22  to the open position, allowing access to the secondary interior  25 . The user may then place the odorous or foul waste within the secondary interior  25  and subsequently close either secondary lid  22 , primary lid  12 , or both. Thus, the waste management receptacle system allows a user to isolate particularly foul, odorous waste separate from other refuse which can be placed within a primary receptacle. When a user with further refuse uses the waste management receptacle system  1 , the user may lift primary lid  12 , thereby exposing interior portion  15 , and place refuse within the interior portion  15  without opening secondary lid  22 . In this manner, particularly foul waste will continue to be isolated, and the user will not be subject to foul odors or smells while using the waste management receptacle system of the present invention. 
     In some embodiments, like those depicted in  FIG.  5   , the secondary receptacle lid may comprise a handle portion  22 ′ to facilitate lifting of the lid. The secondary receptacle lid may also comprise an extension portion  23 , which may be a flexible canvas or nylon strap, and may include a closure end portion  23   a , which may be a magnetic latch mechanism, mechanical latch mechanism, or other detent mechanism in communication with the exterior portion of the primary receptacle sidewall  5 ,  6 ,  7 ,  8  opposite the sidewall portion of the primary receptacle which incorporates hinge  11 . When the primary and secondary receptacle lids are in the closed position, closure end portion  23   a  may be accessible to an end user, and due to contact between extension portion  23  and the primary receptacle lid  12 , mechanical communication between primary receptacle lid  12 , extension portion  23 , and secondary receptacle lid  22  is achieved. Upon release of the detent mechanism formed between the closure end portion  23   a  and the exterior of the sidewall  5 ,  6 ,  7 ,  8 , the end user may lift the closure end portion to access the interior of the waste management receptacle system. Thus, an end user lifting the extension portion  23  may open both primary lid  12  and secondary lids  22  simultaneously providing access to the secondary receptacle interior  25 , and primary receptacle interior  15  for placement of waste within any portion selected by the end user. 
     Turning now to the embodiments depicted in  FIGS.  10  and  11   , secondary receptacle  20  may be attached to the exterior of the primary receptacle. In such a configuration, the clamping member is placed on the interior portion  15  of the primary receptacle  10 . Such embodiments are similar in function as other embodiments described herein, but advantageously does not require the user to remove the primary receptacle lid  12  to access the interior portion  25  of the secondary receptacle  20  for placement of foul or odorous waste therein. 
     During collection of the waste management system of the present invention, a waste collection service may dispose of the waste within the waste management system  1  by inverting the primary receptacle  10  (after removal of lid  12  for receptacles which are not hinged) allowing gravitational forces to cause waste to be freed from the interior portion  15  of the primary receptacle, while secondary lid  22  may simultaneously be moved to an open position, thereby exposing secondary interior  25 , allowing the odorous or foul waste to be subsequently fall via gravitational forces from the secondary interior  25 . After returning the waste management system  1  to a right-side-up position, a user may subsequently return primary and secondary lids  12 ,  22  to the waste management system  1 . Advantageously, the closure of primary lid  12  to secure the primary receptacle will cause secondary lid  22  to subsequently close and secure the secondary receptacle, thereby providing a timesaving benefit to the end user. 
     In some embodiments, like those shown in  FIGS.  14  and  15   , the primary receptacle  10  may include sidewall contour portions  5 ′,  6 ′,  7 ′,  8 ′ to facilitate removal of waste within the interior portion  15 . As depicted, secondary receptacle  120  is of a substantially rectangular configuration having bottom  124  with sidewalls  126  having contoured edges  126 ′ and hinged lid  122 . Advantageously, the secondary receptacle  120  having contoured edges  126 ′ may be placed at the contoured corner portions  5 ′,  6 ′,  7 ′,  8 ′ between one or more sidewalls  5 ,  6 ,  7 ,  8  to facilitate ease of placement of waste within the interior portion  15  of primary receptacle  10 . While the secondary receptacle bottom depicted has contoured edges and a flat bottom, other similar geometric configurations are not meant to be precluded. 
     In one or more embodiments, the secondary receptacle  20  may include a receptacle liner portion  40 , like those depicted in  FIGS.  4 ,  7 , and  12 - 13   . Receptacle liner portion  40  includes container base  44  having vertically extending sidewalls  46  forming container interior  45 . Liner portion  40  may be designed for placement within the secondary receptacle  20 , and thus may be of a complementary structure thereof. Liner portion may be constructed of any soil resistant material such as silicone, or polymer plastic to produce a reusable and durable liner portion. To secure liner portion  40  within the secondary receptacle interior  25 , liner portion may include an attachment structure  41 , which may comprise one or more magnets, tabs, slots, openings, or grooves on sidewall portions  46 . As shown in the exemplary views of  FIGS.  4 ,  7 , and  12 - 13   , the liner portion sidewalls  46  include slots as attachment structure  41 , which are received by rotatable projecting tabs  27   a  extending from projecting stem  27   b  of the secondary receptacle  20 . After receiving the projecting tabs  27   a  within the attachment structure  41 , an end user may rotate the tabs  27   a , forming a detent mechanism to hold the liner portion  40  within the secondary receptacle  20  when the waste management system  1  is inverted. Advantageously, lining portion  40  may include a flanged seal or gasket around the rim  48  to facilitate further sealing between the secondary receptacle interior and lining portion interior, preventing fouling of the secondary receptacle as well as prevention of odors emitting from the secondary receptacle when the secondary lid is closed. Due to the construction of the lining portion, a user may remove and clean the lining portion after becoming fouled with odorous waste including pet feces simply by releasing detent mechanism achieved by the attachment structure  41 . Thus, the lining portion may be removed from the waste management receptacle system  1  without need to remove clamping member  30  from the primary receptacle  10 . 
     Thus, the present invention provides one or more of the following advantages: (1) a waste management receptacle system with separate compartments for the containment of foul or odorous waste; (2) an auxiliary waste receptacle system for use with an existing waste receptacle for the containment of foul or odorous waste; (3) a separate waste receptacle in a waste receptacle system to control particularly noxious odors within a separate compartment; and (4) a removable waste receptacle system which would prevent squishing or sticking of odorous organic waste to a waste receptacle system. 
     While the present invention has been particularly described, in conjunction with one or more specific embodiments, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention. 
     Thus, having described the invention, what is claimed is:
