SYSTEM AND METHOD FOR RECYCLING MATERIALS

Abstract: First and second washing machines (13, 15) are utilized to clean plastic (87) and cellulose (53) from disposed diapers (49) for recycling. The disposed diapers (49) are loaded into the first washing machine (13) and, while being agitated by rotation of a basket (37) and by air supplied by a blower (23), are washed in water, alkali and soap. During washing, the cellulose becomes separated from the plastic. The cellulose is drained out of the first washing machine with the water, leaving the plastic in the first washing machine. The plastic is then cleaned in the first washing machine. A pump (17) transfers the cellulose and water to the second washing machine (15). In the second washing machine, the cellulose is washed in alkali and soap while being agitated. The second washing machine has a screen (48) for retaining the cellulose therein, while passing the water and waste material. Wood pulp goods, rubber, glass and plastic are other materials that can be processed and cleaned for recycling purposes.

Description: SYSTEM AND METHOD FOR RECYCLING MATERIALS Specification Field of the Invention The present invention relates to systems and methods for separating and cleaning materials from waste products such as disposed diapers and disposed newspapers. Background of the Invention Disposable diapers are primarily made up of plastic and cellulose. The plastic provides a moisture-proof lining on the outside of the diaper and the cellulose provides the bulky absorbent media on the inside. The diaper essentially provides a bag that is worn by a human being. The cellulose holds and retains all moisture, while the plastic ensures that there is no leakage through the bag. Some disposable diapers are marketed under names such as "ultra thin" or the like. These diapers use less cellulose and include a super absorbent molecule (SAM) , which absorbs as much as one thousand times its own mass in water. Disposable diapers have become immensely popular. Disposable diapers of course are used just once and thrown away after they have been soiled with waste material. The ultimate disposal of the diapers typically involves transporting them to the local landfill. Environmentalists decry this disposal of diapers as being wasteful both in the manufacture and disposal of the diapers. The manufacture of disposable diapers requires forest products to obtain the necessary cellulose, while the disposal of the diapers utilizes valuable landfill space. Many communities around the country are seeing the exhaustion of their landfill space in conjunction with the political difficulty of finding new landfill space. Thus, there is a real need to reclaim the materials in disposable diapers. The same can also be said of newspapers, which are read and then thrown away. Recycling of newsprint from newspapers has been going on for some time. A typical first step in recycling materials such as newsprint is cleaning to remove any contaminants. In the case of newsprint, the paper is cleaned to remove ink. Prior art methods of recycling newsprint involves soaking the newsprint in vats. The newsprint is then transferred to other, successively cleaner vats. Unfortunately, the ink follows the newsprint from vat to vat, making it difficult to satisfactorily clean the newsprint. Other materials, such as rubber and glass, are cleaned in the first steps of recycling. Summary of the Invention It is a object of the present invention to provide a system and a method for recycling materials, such as plastic and cellulose, from disposed products such as disposable diapers. It is a further object to recycle products containing plastic and cellulose by separating the plastic and other noncellulose materials from the cellulose and cleaning the materials. It is a further object of the present invention to provide a method for cleaning soiled wood pulp goods such as cellulose and newsprint from newspapers. Still another object of the present invention is to provide a method for cleaning rubber goods, such as used tires, for recycling. Still another object of the present invention is to provide a method for cleaning glass objects for recycling. Still another object of the present invention is to provide a method for composting organic waste such as food and yard waste. The method of the present invention cleans cellulose material and noncellulose materials such as plastic, rubber and glass from disposed products. A washing machine is provided for washing the disposed products. The disposed products, water, alkali and a surfactant are loaded into a perforated basket in the washing machine. The basket is moved so as to agitate the goods. The water, alkali, surfactant and contaminants are drained out of the basket through the perforations, while the goods are retained in the basket. In one aspect of the present invention, the goods being cleaned comprise cellulose material and noncellulose material. The step of moving the basket causes the cellulose material to separate from the noncellulose material. The step of draining further comprises the step of draining the cellulose material from the basket through the basket perforations while retaining the noncellulose materials in the basket. The cellulose material is transferred to a second washing machine having a perforated second basket. The basket is moved so as to agitate the cellulose material, water, alkali and the surfactant. The water, alkali and surfactant are drained from the second basket through perforations, while retaining the cellulose material in the second basket. In still another aspect, the goods being cleaned comprise rubber goods such as tires. Before the goods are loaded into the basket, the rubber goods are shredded so as to produce rubber particles. In still another aspect of the present invention, the goods being cleaned comprise soiled wood pulp goods such as cellulose and newspaper. The step of loading the goods, water, alkali and surfactant further comprises adding sufficient alkali so that the mixture of goods, water, alkali and surfactant has a pH of between 10.5 and 14. In addition to moving the basket so as to agitate the goods, air can be blown into the basket to further agitate the goods. Also, ozone can be injected into the basket during the agitation process so as to sterilize the goods. The system of the present invention recycles cellulose material and noncellulose from disposed products. The system includes a first washing machine, a second washing machine and transfer means. The first washing machine is for washing goods and includes a first chamber and a first basket. The first chamber is adapted to contain water and has a drain for draining the contents of the first chamber. The first basket is contained in the first chamber and is adapted to contain the products. The first basket is perforated so as to pass a mixture of the cellulose material and water therethrough and so as to retain the noncellulose inside of the first basket. The first basket is movable so as to agitate the products inside thereof. The second washing machine is also for washing goods and includes a second chamber and a second basket. The second basket is contained in the second chamber. The second chamber is adapted to contain water and has a drain for draining the contents of the second chamber. The second basket is perforated with smaller perforations than the perforations of the first basket so as to pass water therethrough while retaining the cellulose material therein. The second basket is movable so as to agitate the contents thereof. The second washing machine has input means for receiving said cellulose material into said second washing machine. The transfer means is for transferring the mixture of cellulose material and water from the first washing machine to the second washing machine input means. The transfer means has an input that is connected to the first chamber drain and has an output that discharges to the second chamber input means. In one aspect, the systen of the present invention provides that the first basket is lined with a first mesh, which first mesh provides the appropriate sized first basket perforations so as to pass a mixture of said cellulose material and water therethrough while retaining said plastic inside of said first basket. The second basket is lined with a second mesh, which second mesh provides the appropriate sized second basket perforations so as to pass water therethrough while retaining said cellulose material inside of said second basket. There is also provided a method for processing waste material such as food and yard waste. A washing machine is provided that is suitable for washing textiles. The washing machine has a basket that is perforated so as to pass water but retain the waste material. The waste material, water and either acid or alkali are loaded into the basket. The basket is moved so as to agitate the waste material. While moving the waste material, air is injected into the basket.

Description of Preferred Embodiments The system and method of the present invention involves the recycling of disposed products such as disposable diapers that have been soiled with waste material. Disposable diapers typically are made up of plastic and cellulose. The plastic provides a moisture-proof barrier, while the cellulose, which is located inside of the plastic, acts as an cellulose media to hold and retain fluids. The system and method of the present invention recycles the plastic and cellulose in the soiled diapers. The plastic and cellulose are separated from each other during an initial cleaning step. Then, the plastic and cellulose are separately cleaned of all waste material. The waste material is discharged, typically into a sewer system, for proper sanitary disposal. The cleaned cellulose and plastic can be sold and reused in manufactured products. In Fig. 1, there is shown a schematic side view of the system 11 used to practice the method of the present invention, in accordance with a preferred embodiment. The system includes a first washing machine 13, a second washing machine 15, a transfer pump 17 between the first and second washing machines, a first infeed conveyor 19, a second infeed conveyor 21 and blowers 23. The first and second washing machines 13, 15 are substantially similar to each other. The washing machines are continuous batch washing machines which are typically used for the washing of textile goods such as clothes. The washing machines are conventional and commercially available. The washing machines in the preferred embodiment are Model 76032 continuous batch washers, manufactured by Pellerin Milnor Corporation of Kenner, Louisiana, U.S.A. Each machine has plural chambers 25 for washing goods therein. The chambers 25 are waterproofed so as to hold the wash water. Referring to Fig. 2, each chamber is formed by side walls 27 and a cylindrical outer wall 29. The chambers 25 in each washing machine are arranged side-by-side in a row such that the side walls 27 are adjacent to each other. Each chamber 25 in a washing machine has a basket 37 for holding the goods to be washed. Each basket 37 has a cylindrical outside wall 39 and two side or end walls 41. A longitudinal axis extends between the side walls 41. The baskets 37 in each washing machine are arranged so that their longitudinal axes are colinear. Each washing machine has an inlet 31 communicating with one of the end baskets and an outlet 33 communicating with the other of the end baskets. Each basket 37 communicates with its adjacent baskets by way of openings 35 in the side walls 41. The goods to be washed are loaded into the washing machines at the respective inlet 27, travel through the baskets 37 one by one while being washed, moving from chamber to chamber by way of the openings 35, and are discharged from the machines at the respective outlet 33. Each washing machine has a motor 36 for rotating the baskets 37 about their horizontal longitudinal axes within the fixed chambers 25. All of the baskets rotate in unison and in the same direction. Rotation of the baskets causes the goods inside to be agitated, thereby increasing the effectiveness of the wash. Each basket 37 is provided with ribs 43, as shown in Fig. 3, to further increase the agitation of the goods. The ribs 43 are mounted to the inside surface of the outside wall 39 and are spaced apart. As the basket 37 is rotated, the goods are lifted and dropped by the ribs 43. The basket 37 rotates about 300 degrees in one direction and then reverses to rotate 300 degrees in the other direction. This reversing of the direction of rotation further increases the agitation of the goods. The time it takes for a basket to rotate 300 degrees in one direction and 300 degrees in the other direction is about 11 seconds. The goods are transferred from one basket to the next basket in a conventional manner by rotating the baskets beyond 300 degrees. As a basket rotates beyond 300 degrees, the goods enter a conventional scoop on the basket that allow the goods to pass from the basket into the next adjoining basket (or if the basket is the last basket, then the goods pass to the outside of the washing machine) . The outside wall 39 of each basket 37 is perforated with numerous openings 45, 47. The openings 45 allow water to be drained from the baskets. The size of the openings 45, 47 in the baskets in the first and second washing machines 13, 15 differ. In the first washing machine 13, the first two baskets 37A, 37B have openings 45 that are sized so as to retain the plastic portion of the diapers while allowing the cellulose, waste material and water to pass therethrough. It has been found that stainless steel 304 wire mesh 46, with a wire diameter of .012 inches and having 30 wires per inch, works satisfactorily. In the second washing machine 15, all of the baskets 37C have openings 47 that are sized to retain the cellulose inside of the basket, while passing water and waste material (see Fig. 4) . It has been found that stainless steel 316 wire mesh 48, with a wire diameter of .010 inches and having 40 wires per inch, works satisfactorily. In Figs. 2 and 4, the wire mesh 46, 48 and the openings 45, 47 have been shown schematically, in order to better illustrate the openings. The baskets 37 are modified to provide the appropriate sized openings. The baskets in a washing machine are manufactured with openings of a relatively large size in the outside wall. To provide the proper size openings, the appropriate sized wire mesh is coupled to the inside surface of the outside wall 39 of a basket by welding. Alternatively, the wire mesh could be coupled to the outside wall by way of buttons, which buttons are coupled to the screen mesh and which snap fit into some of the openings in the outside wall 39. Each chamber 25 has a drain opening 55 located at the bottom of the chamber. Drain pipes 57 lead from the drain openings 55 to the next adjacent chamber which is nearest to the inlet 31. This provides a flow of wash water from chamber to chamber which is counter to the flow of goods from chamber to chamber. The goods proceed from the inlet 31 to the outlet 33, while the wash water proceeds from the outlet to the inlet. This counterflow conserves water. Fresh or clean water inlets 59 are provided at the last chamber and may be provided at other chambers as desired. The last chamber, which is adjacent to the outlet 33 has its drain connected to a make up tank 34. Thus, the water in the last chamber is drained into the make up tank 34. The make up tank has an outlet 34a, which is connected to an inlet 59a on the first chamber. Thus, the make up tank can be used to provide water to the first chamber. The first two chambers of the first washing machine 13 have drain pipes 61 that lead from the respective openings 55. The drain pipes 61 are both connected to the input of the pump 17. The pump 17 is a conventional, commercially available nonclogging process pump which is suitable for pumping fluids with entrained solids and fibrous materials. The output of the pump 17 is connected to a conduit 63 that discharges onto the second conveyor 21 for the second washing machine 15. The conduit 63 discharges onto the conveyor 21 at a location that is within a drain tank 65. Dump valves 67 are provided in each of the drain pipes 61 leading from the first two chambers of the first washing machine. The dump valves 67 control the draining of the fluids from the first two chambers. A check valve 69 is provided in the discharge conduit 63 from the pump. The check valve 69 prohibits back flow into the pump and the chambers. Each washing machine 13, 15 has an input conveyor 19, 21 for loading the goods to be washed into the respective first basket. Each washing machine is provided with a funnel 71 for receiving the goods and channeling them into the inlet 31. The input conveyors 19, 21 convey the goods from draining tanks 73, 65, usually located on the ground, up to the funnels 71, where the goods are dumped. The conveyors each have a perforated surface to allow the materials to drain before being loaded into the washing machines. Each drain tank 73, 65 is provided with a floor drain 75 that is connected with the drain system. Other loading devices, such as slings or chutes, could be used in lieu of conveyors. Each washing machine is also provided with a blower 23 for injecting air into each of the chambers of the washing machine. The blowers 23 are connected to the washing machine chambers by way of conduits 76. The air conduits 76 are connected to the chambers at locations that are beneath the respective baskets such that air bubbles up into the baskets. Referring to Fig. 3, which shows a portion of the chamber outer wall 29, the conduit 76 is connected to a plenum 78 coupled to the outer wall 29. An opening 30 is provided for air to escape from the plenum and into the chamber. The opening extends from one chamber side wall 27 to the other side wall, to distribute the air across the basket. The opening 30 is located about 45 degrees from the bottom of the chamber. This assures that the air flow will not be blocked by material that accumulates in the bottom of the chamber. The addition of air to the washing process initiates and speeds up the biological break down of the waste material in the disposed diapers. The blowers are conventional, commercially available units. In the preferred embodiment, the blowers provide 200 to 500 cubic feet per minute of air at about 5 psig to each washing machine. In addition to the blowers, there is provided an ozone generator 24 for each washing machine (see Fig. 1) . The ozone generator 24 is conventional and commercially available, and typically includes a spark gap enclosed in a housing. As a spark forms across the electrode gap, ozone is formed. A pump 26 transfers the ozone from the generator 24 to the respective conduit 76. The ozone sanitizes the goods in each washing machine by killing bacteria. By using ozone, the use of chlorine bleach can be eliminated. Ozone is also introduced into the make up tank 34. The outlet of each washing machine is made up of a ramp 77 that dumps the goods from the last chamber to a bin 79. The goods in the bin 79 of the second washing machine are transferred to a sling 81 (see Fig. 5) for draining and transport to an extractor 83 (see Fig. 6) . The sling is made of mesh material, so as to allow the goods inside to drain while being transported by a cable 85. The extractor 83 is conventional and commercially available. The extractor compresses the moisture out of the goods. The extractor 83 is modified by fitting it with the same type of mesh screening as is in the second washing machine 15. As the extractor presses cellulose, the screening retains the cellulose inside of the working volume of the extractor. The method of the present invention will now be described. Referring to Fig. 1, the disposed diapers 49 are loaded onto the first washing machine conveyor 19 at a collection point. The collection point is located within the drain tank 73 so that fluids may drain out. The disposed diapers are soiled with urine and fecal material. No preprocessing, such as shredding or opening, of the diapers is required. The diapers 49 are loaded into the first basket 37A of the first chamber of the first washing machine 13. There, the diapers are mixed with water, alkali and soap (or a surfactant) . The water is fresh, clean, cold (75 degrees F) water from a water inlet 59 connected to the first chamber. The particular alkali used in the preferred embodiment is orthosilicate. A sufficient amount of alkali is added to raise the pH of the mixture to the desired level, between 10.5 to 14. Higher pH mixtures are required for greasier items. In practice it has been found that pH levels of 13-14 work well. The soap has a neutral pH of 7. The first basket is rotated back and forth around its longitudinal axis so as to agitate the mixture. While being agitated, the cellulose in the diapers become separated from the plastic. In addition, the process of cleaning the waste material from the cellulose and the plastic is begun. The high pH caused by the alkali makes the soil or waste release from the cellulose and the plastic much easier. The neutral soap holds the released waste material in solution in the water, preventing the waste material from reattaching to the cellulose and plastic. Air provided by the blower 23 and ozone provided by the ozone generator 24 bubble up from the bottom of the chamber to enter the basket and further increase the agitation of the mixture, thereby assisting in the separation of the cellulose from the plastic. The increased agitation provided by the air also serves to mix the chemicals in the wash liquor faster, causing rapid displacement of the chemicals through the wash liquor and into the goods. Wash times are shortened by the blowing in of air. In addition, the air aerates the water mixture to provide favorable conditions for the biological breakdown of the waste materials and the ozone sanitizes the plastic and cellulose. Furthermore, blowing in air from the outside of the basket prevents the basket perforations from clogging with the goods that are being washed. After the diapers have been washed for a predetermined period of time in the first basket, for example about 10 minutes, the dump valves 67 are opened, allowing the first chamber and the first basket 37A (and the second chamber and second basket 37B) to drain. The plastic 51 is retained inside of the first basket by the screen mesh, while a sludge-like fluid drains out of the basket 37A and the chamber. The sludge-like fluid is made up of water, the separated cellulose, the waste materials and the alkali and soap. The first basket, in conjunction with the other baskets in the first washing machine, is then rotated past 300 degrees so as to transfer its contents to the next basket, namely the second basket 37B. The contents of the second basket are washed as described with respect to the first basket, in order to separate any remaining cellulose from the plastic. After the wash cycle has been completed in the second basket, the dump valves 67 are opened, allowing the second basket 37B and the second chamber to drain. Because the first washing machine 13 is of the continuous type, the first basket 37A is loaded with dirty diapers 49 each time after it empties into the drain and into the second basket. This maintains a continuous flow of materials through the system. The operation of the loading conveyors 19, 21 is intermittent, to operate only when the respective first basket needs to be loaded with goods. Both dump valves 67 operate together to open and then close in unison. The contents of the second basket empties into the third basket. By this stage, the contents of the third basket is plastic 51 that is free of cellulose, the cellulose having been separated and drained away in the first two baskets. As the plastic continues through the remaining chambers of the first washing machine 13, the plastic is washed in warm water (130 degrees F) and in alkali and soap to clean the plastic of all waste material. About midway through the first washing machine 13, sand is introduced into the machine at inlet 60 so as to form a slurry of sand, plastic and water. The sand is used to assist cleaning the typically smooth plastic material. The sand provides friction points so that the agitation of the plastic by the basket and air more thoroughly cleans the plastic. The sand is of the type used for sand blasting. The sand travels with the plastic through the first washing machine from the basket where it is introduced to the last basket. The baskets are modified by coupling 316 wire mesh to the inside of the basket wall. The mesh retains the plastic inside of the basket to prevent the smaller plastic material from entering the drain of the respective chamber. In the last basket or module, the basket is modified to provide two layers of mesh. An inner layer of mesh is 304 mesh and during the washing cycle (and rotation of the basket) passes the sand while retaining the plastic. Surrounding the outer circumference of the inner layer of mesh is an outer layer of 316 mesh. The inner and outer layers of mesh are separated from each other by a space of 12-18 inches. (Such a nested arrangement of meshes or baskets is shown in Fig. 11 and is described in more detail herein below.) This space traps the sand, as the sand does not pass through the outer layer of mesh. In the last module then, the sand is separated from the plastic. The sand passes into the trap between the two layers. The sand is recovered from the trap and then piped back into the machine through inlet 60. The plastic is removed from the washing machine and loaded onto a wet conveyor. The transfer from the washing machine may be either manual or by mechanical means. While on the conveyor, the plastic can be sorted according to color, etc. One problem with prior art methods of recycling plastic has been the removal of inks from the plastic. Inks are typically used to print information on the plastic. If the ink is not removed, then the recycled plastic typically is colored by the inks, thereby reducing the commercial appeal of the recycled plastic. Use of sand cleans, by abrasion, the inks off of the plastic, enabling the plastic to be recycled back to its original color and free of coloration by the inks. This method of cleaning ink off of plastic applies to any type of plastic, not just the plastic components of diapers. For example, plastic candy wrappers can be deinked with this method. The plastic can be laminated with plural layers of plastic, or with layers of paper. As an alternative to sand, a water soluble aromatic solvent, such as mineral spirits or paint remover, can be used to remove any elastic and labeling that is attached to the plastic. As still another alternative, both sand and an aromatic solvent can be used. During the washing process, a sterilizing agent may be added to sterilize the plastic. Ozone from the ozone generator 24 can be used. Alternatively, chlorine bleach may be used. However, the use of sand reduces the need for ozone or bleach. The water-cellulose sludge that has been drained out of the first two baskets of the first washing machine 13 enters the pump 17, which then pumps it through the conduit 63 to discharge onto the second conveyor 21 loading the second washing machine 15. The loading point of the second conveyor 21 is located within the drain tank 65, wherein much of the water and associated waste material drains out of the cellulose before the cellulose is loaded into the second washing machine 15. The water-cellulose sludge 89 is then loaded into the first basket of the second washing machine 15. The cellulose is washed in hot water (about 170 degrees F) , alkali and soap. After the washing cycle, the dump valve 91 in the first chamber is opened, allowing the first chamber to drain into the drain system by way of the drain pipe 90. The wire mesh in the baskets of the second washing machine, which has smaller openings than the wire mesh in the first washing machine, retains the cellulose inside of the baskets. The cellulose in the first basket is then transferred to the second basket, wherein it is washed again in hot water, alkali and soap. A sufficient amount of alkali is added to raise the pH of the mixture to the desired level, between 10.5 to 14. In practice, it has been found that pH levels of 13-14 work well. In the next basket, the cellulose is rinsed with hot water and in the fourth basket, the cellulose is washed with bleach. The bleach, which can be chlorine bleach, hydrogen peroxide or oxalic acid, whitens and sanitizes the cellulose. The cellulose is then rinsed with water and then rinsed with water and sour, or sodium fluorocarbate, to bring the pH down to about 6.5 to 7.0. The cellulose 53 is discharged from the last basket of the second washing machine 15 and is loaded into a sling 81 as shown in Fig. 5. The sling 81 is formed from a net that retains the cleaned cellulose and allows water to drain out. The sling is mounted onto a cable 85, which moves the sling from the outlet of the second washing machine 15 to the input of the extractor 83. The contents in the sling are loaded into the input of the extractor. The extractor 83 presses the cellulose into a block 93 so as to extract the water in the cellulose. Mesh screening in the extractor retains the cellulose inside while allowing water to pass through. The resulting block 93 of cellulose is then moved along a conveyor 95 from the extractor to a shipping or storage location. After being pressed in the extractor, the cellulose can be loaded into a drier to remove any moisture. The drier is a conventional, commercially available device that has been modified. The drier has a rotating basket. The perforations of the basket are reduced by coupling the same type of mesh screen as in the second washing machine 15. The mesh screen retains the cellulose inside of the basket. The plastic can also be dried in a drier, although separately from the cellulose. Some diapers reduce the amount of cellulose required to absorb moisture by adding a substance referred to in the industry as super absorbent molecule (SAM) . It is believed that SAM is a type of acrylic polymer. SAM absorbs many times its own weight in moisture. The SAM is separated from the plastic in the first washing machine 13, along with the cellulose. The SAM is then pumped with the cellulose to the second washing machine 15. In the second washing machine, the SAM may be neutralized and removed from the cellulose. Before and after the cellulose has been washed with alkali and soap, the cellulose is washed in water and either sodium silicofluoride (or sodium fluosilicate) or sodium chloride. The sodium silicofluoride neutralizes the SAM, and allows it to be drained out of the cellulose with the rinse water. The water that enters the drain system from the washing machines 13, 15 is of course contaminated with the waste material from the disposed diapers. This waste water can be drained into a municipal sewer system, where it will treated by the municipal sewage treatment plant. Alternatively, a dedicated sewage treatment plant can be utilized to treat the waste water from the recycling process. An alternative method will now be described. In this method, the first washing machine 13 is provided with four modules or chambers, while the second washing machine 15 is provided with seven modules or chambers. The soiled diapers are loaded into the first basket of the first washing machine 13, which is in the first module. 100 degree Fahrenheit water and sour are also added to the first module. Enough sour is added to achieve a wash liquor pH of about 5.5. The basket is then rotated and air is blown in with the blower 23. During the washing process in the first module, the diapers stay intact and are cleaned of some of the waste material. The dirty wash water and waste material exit the module through the drain, leaving the diapers inside of the first module basket. The water and waste material exit to the sewer system. The sour effectively reduces to a smaller size the superabsorbent molecules, or other absorbent polymer, that is located in the diapers. The wash process in the first module reduces the weight and volume of the diapers by about one-half. After being washed in the first module, the diapers are transferred into the basket of the second module. There, they are washed in 195 degree Fahrenheit water, a neutral surfactant and sufficient alkali to raise the pH of the wash liquor to about 12.5. The diapers are agitated by basket movement and by blown in air. The diapers break apart, allowing the cellulose and the plastic to separate. Much of the cellulose exits the basket during draining, wherein the cellulose is pumped into the second washing machine. What cellulose that remains inside the basket, along with the plastic, is transferred into the basket of the third module. There, the cellulose and plastic are rinsed with water. The cellulose in the third module drains out of the respective basket, wherein it is pumped into the second washing machine. The plastic that remains in the third basket is transferred into the basket in the fourth or last module. The plastic is rinsed again with water in the last module, after which it is removed from the washing machine. The fourth module may be fitted with an inner basket to remove insoluble contaminants from the plastic. This arrangement is shown in Fig. 11 and will be described in more detail hereinafter. In both the first and second washing machines, the goods located inside of the baskets are agitated by a rotation of the respective basket and by blowing in air from the bottom of the module into the basket. The cellulose that is loaded into the second washing machine 15 is washed as previously described. The superabsorbent molecule that was reduced in the first washing machine is separated from the cellulose and drained out of the basket through the basket perforations. As the cellulose proceeds through the modules of the second washing machine, more and more of the superabsorbent molecule is washed from the cellulose. Thus, the cellulose that is removed from the end of the second washing machine is cleaned and free of superabsorbent molecule. In Fig. 7, there is shown a recycling system 101 in accordance with another embodiment. The system of Fig. 7 uses first and second washing machines 103, 105 of the batch type, rather than of the continuous type, as described above with reference to Fig. 1. Each of the first and second washing machines 103, 105 has a single basket and chamber therein. Such a system is utilized for small recycling operations, where the amount of diapers being recycled does not justify the expense of purchasing the continuous washers of Fig. 1. The basket of the first washing machine 103 is lined with wire mesh that is similar to the wire mesh 46 in the continuous type first washing machine 13 so as to retain the plastic therein and pass the cellulose therethrough. The first washing machine 103 has a drain conduit 107 for draining away all waste water and the cellulose. The drain conduit has a T fitting, with one branch of the drain leading to a pump 109 and the other branch leading to the drain system 111. Both branches have a dump valve 113, 115 for controlling the flow therethrough. A length of conduit 117 is connected to the output of the pump 109. A check valve 119 is provided in the conduit 117 adjacent to the pump 109. The conduit 117 discharges into the top of a holding tank 121 located above the second washing machine 105. The holding tank 121, which is shown in Figs. 7 and 8, allows the cellulose to drain before it is loaded into the second washing machine 105. The holding tank 121 is supported above the second washing machine 105 by mounting structure 122. The holding tank 121, which is open on top, has four side walls 123, 125 and a bottom wall 127. One of the side walls operates as a door 125, moving between open and closed positions. The tank 121 has a false bottom wall 129 of wire mesh, such that there is a gap between the two bottom walls 127, 129. The wire mesh 129 allows water to drain therethrough, but retains the cellulose. A drain opening 131 is located in the bottom wall 127. A drain conduit 133 connects the drain opening 131 with the drain system. The holding tank 121 is provided with a water jet 135 beneath the wire mesh for cleaning off the wire mesh 129 with a spray of water. The holding tank 121 is movable between a hold position and a discharge position. In the hold position, the tank 121 is substantially level so as to hold the cellulose therein; except the tank is tilted just slightly so as to locate the drain opening 131 at the lowermost position. A hydraulic piston actuator 137 moves the tank 121 to the discharge position, wherein the tank is tilted up as shown by the dash lines in Figs. 7 and 8. In the discharge position, the door 125 swings open and allows the cellulose to fall into the basket of the second washing machine 105 by way of a loading port 139. The second washing machine 105 is provided with the topside loading port 139, a drain conduit 141 and a dump valve 143. The basket of the second washing machine 105 is lined with wire mesh that is similar to the wire mesh 48 in the continuous type second washing machine 15 so as to retain cellulose therein while passing water and waste material therethrough. Both washing machines 103, 105 are provided with blowers 145 to aerate the goods being washed. The ozone generators 24 and pumps 26 of Fig. 1 can also be used with the arrangement of Fig. 7 so as to provide ozone to the washing machines 103, 105. To recycle diapers with the system of Fig. 7, a load of diapers is put into the first washing machine 103. The first washing machine has a door 147 that is used for loading and unloading. Assuming that the first washing machine 103 has a capacity of 275 pounds, the diapers are first washed in 75 degrees F water with eight ounces of alkali for ten minutes. Then, the dump valve 113 to the pump 109 is opened and the first washing machine drains, with the pump 109 pumping the water-cellulose sludge into the holding tank 121. After draining for two minutes, the dump valve 113 is closed. Next, the contents of the first washing machine 103 are washed in warm water (130 degrees F) , with four ounces of alkali and soap for ten minutes. Then, the dump valve 113 to the pump is opened for two minutes, wherein the pump 109 transfers the sludge from the first washing machine 103 to the holding tank 121. The pump 109 operates whenever the dump valve 113 is opened. All of the cellulose in the first washing machine has by now been drained out, leaving the plastic. Sand (and/or an aromatic solvent) is introduced into the first washing machine so as to clean the plastic of ink and other contaminants. The plastic is washed as described above, using water, a surfactant, alkali (if needed) , and a sterilizing agent such as ozone and agitation (both from the moving basket and the blown in air) . When the plastic is clean, the sand is separated from the plastic by a perforated basket. The sand can be separated in the first washing machine 103, if the basket has proper size perforations (such as a double wall described above with respect to the machine 13) or in another machine. The water-cellulose sludge that has been pumped by the pump 109 is allowed to drain in the holding tank 121. The cellulose is then dumped into the second washing machine 105 by way of the loading port 139, where it is washed in water (170 degrees F) , eight ounces of alkali and soap for ten minutes. The dump valve 143 is then opened for two minutes, allowing the water and waste material to dump into the drain system 111. The cellulose is again washed in water (170 degrees F) with ten ounces of alkali and soap for ten minutes. The dump valve 143 is opened for two minutes. The cellulose is rinsed for two minutes with water (170 degrees F) , followed by opening the dump valve for two minutes. Then, the cellulose is washed in one quart of bleach and 150 degrees F water for ten minutes, followed by opening the dump valve for two minutes. Alternatively, ozone can be used as a sterilizing agent. The cellulose is rinsed with 130 degree F water for two minutes, followed by opening the dump valve for two minutes. Next, the cellulose is rinsed in 110 degree F water for two minutes, before the washing machine is dumped to the drain system for two minutes. Then, the cellulose is washed for five minutes in a rinse of 75 degree F water and six ounces of sour. The washing machine is dumped to the drain system and the cleaned cellulose is unloaded. The cellulose is put into a sling 81 and then transferred to an extractor 83 to extract moisture, as described above. In addition to recycling plastic and cellulose from disposed diapers, I have found that the method and system of the present invention also recycles many other disposed products and items. Before reprocessing recycled materials into new products and items, the materials must first be cleaned of oils and greases, soils, etc. Many products are similar to disposed diapers in that they contain cellulose materials and noncellulose materials (such as plastic, metal parts, etc.) . I have found that items such as peanut cans, frozen juice cans, corrugated boxes and the like can be recycled. With peanut cans and frozen juice cans, the metal rims and plastic lids are retained and washed in the first washing machines, while the cellulose or paper making up the stiff paper walls of the cans is washed in the second washing machine as described above with respect to diapers. With corrugated boxes, the metal and plastic (for example, metal staples and plastic shipping labels) are separated from the cellulose making up the walls of the boxes in the first washing machine. The cellulose passes out of the first washing machine to be washed in the second washing machine. Cereal boxes (rectangular and cylindrical such as Quaker Oats containers) can be recycled into cellulose (the box walls) and plastic (the inner liner) . Milk and juice cartons can be recycled into cellulose and plastic materials. Disposable food containers such as cups and utensils can be recycled into plastic and cellulose materials. A vapor barrier bag can be recycled into cellulose and plastic materials. By rotating the basket and blowing in air to agitate the goods, the cellulose making up the walls of these containers breaks down sufficiently to pass through the first basket mesh, thereby enabling separation of the cellulose from the noncellulose materials. Other items that can be processed are plastic items such as plastic wrappers (e.g. candy wrappers, cigarette wrappers) . Also, plastic containers can be washed and recycled. One particularly difficult type of plastic container to recycle is a motor oil container. Even though the containers are made of recyclable plastic, recycling is discouraged because of the difficulty of cleaning the oil off of the plastic. One method of processing plastic oil containers is to grind or chip the containers into small pieces. These pieces, which may be the same size as the tires discussed below, are then washed in a washing machine 13. The pieces are washed in 180 degrees Fahrenheit water, sand, a neutral surfactant and alkali. Washing removes the oil from the pieces. In addition, the sand cleans any paint, labels, and other non-plastic materials off of the plastic pieces. I have also found that the method and system of the present invention also recycles soiled wood pulp products such as newsprint and waste paper. Newsprint is from newspapers. Waste paper includes disposed office paper such as writing paper, typing paper or copier paper. The present invention cleans ink off of the paper. For example, newsprint is similar to the cellulose found in diapers and as such can be cleaned with the same system and methods for cleaning cellulose. Newsprint and cellulose are both made from wood pulp. To recycle waste paper such as newspapers, a load of newspapers is put into the second washing machine 15, 105. The same washing process as described above with washing the cellulose in the second washing machine is utilized to wash the newspaper. However, slightly hotter (185 degrees Fahrenheit) water is used in order to assist in breaking up the inks on the newsprint. The washing process removes the ink from the paper and dumps it into the drain system 111. The wire mesh 48 in the second washing machine retains the paper inside of the basket, while allowing the ink and water to pass therethrough. The cleaned newspaper is removed from the second washing machine 15, 105 and is loaded into the sling 81 and the extractor 83 to extract the moisture from the paper. One problem with prior art methods of recycling newspaper is that the quality (and thus commercial value) of the final product is determined by the condition of the disposed newsprint making up the feedstock. Dirty, sun-baked newspaper is considered to have a lower commercial value than relatively clean (except for the ink) newspaper. My invention is able to clean and process dirty sun-baked newspaper to increase its commercial value. By washing the newspaper in a modified clothes washing machine, any dirt in the newspaper is washed away. Sun-baking typically turns newspaper yellow, due to the high acid content of newsprint. The high acid content is a byproduct of the paper making process. Conversely to the paper making process, my invention uses alkali to clean the newspaper, wherein the pH is raised to high levels. Using an alkaline wash liquor and either ozone or chlorine bleach (or both) the newspaper is whitened, thus raising its commercial appeal. The alkali rejuvenates the cellulose to reduce the brittleness of the cellulose fibers. Also, because the newspaper is washed in an alkaline wash liquor, it is no longer an acidic paper. As such, the recycled newspaper will not deteriorate as rapidly as acidic paper. In addition to recycling materials with cellulose, I have found that the present invention also recycles materials without any cellulose. For example, the present invention recycles rubber vehicle tires that have been disposed of. Prior art methods of handling disposed tires involve either storing the tires in landfills or shredding the tires for burning in an incinerator. Storing the tires in landfills takes land out of production. The insides of the tires also hold water and are therefore a fertile breeding ground for insects such as mosquitoes. Burning tires is wasteful and produces air pollution. Before the tires can be recycled they must be cleaned. The used tires are soiled with grease, road oil and dirt. The polyester belting and the tread are two locations in particular where greases, oils and dirt accumulate and are difficult to remove « To recycle tires with the present invention, the tires are shredded to produce small rubber pellets or pieces. Conventional and commercially available shredders are used. In the preferred embodiment, the pellets range in size from 0.1-1.0 inches. Many tires contain steel and other types of belts. The entire tire, including the belts, is shredded. The tire pellets are loaded directly into the second washing machine 15. The pellets are washed in water, soap (or other surfactant) and alkali. The same washing process as described with respect to the cellulose in the second washing machine is used. The baskets and the air agitates the pellets, wherein the pellets are cleaned of dirt, grease and oil. The ozone injected into the washing machine 15 along with the blower air serves to sterilize the tire pieces. After the tire pieces are washed, they are removed from the washer and are dried. Drying is performed by placing the tire pieces in a dryer. The dryer is modified by lining the inside of its basket with 316 mesh to retain the tire pieces inside of the basket. After drying, the cleaned rubber can be mixed with new rubber to be made into new rubber products. For instance, the cleaned rubber can be vulcanized or melted. Additionally, the present invention can wash other noncellulose materials such as glass containers for recycling. The glass containers, such as bottles and the like, are loaded into the first basket of the second washing machine. Hot water (160 degrees) and a neutral surfactant, such as a mild soap, are added to the first basket. Because glass is impenetrable by water, strong surfactants are not believed to be needed. The first basket is rotated and air is blown into the first basket by the blower, so as to agitate the glass containers. During agitation, it is likely that breakage of some and possibly all of the glass containers will occur. The 316 mesh lining the interior of the first basket will retain all but the tiniest pieces of glass inside of the first basket. During agitation, any labels that were on the glass containers are separated from the glass. Cellulose or paper labels will exit the first basket through the mesh. Ozone can be injected into the chamber to sterilize the glass. If additional cleaning of the glass is required, then additional washing cycles in subsequent mesh lined baskets can occur. When the glass is cleaned, it is removed from the washing machine. The cleaned glass is dried, either in a sling, a tumbling drier, or by passing the glass through hot air. To complete the recycling process, the cleaned glass is melted and formed into new containers or other items. This melting and forming is done in accordance with conventional techniques. The present invention also provides composting organic matter such as food and yard waste (see Fig. 9) . To compost this waste, the material is loaded into the first basket 153 of a washing machine 151. The washing machine, which is typically made for washing clothes and textiles, is modified. The first basket 153 is lined with 316 mesh as in the second washing machine 15 of Fig. 1. Subsequent baskets in the composting machine 151 are lined with finer meshes (having smaller perforations that the first basket mesh perforations) . Thus, the perforations of the mesh in the second basket 153A of the composting machine are smaller than the perforations of the first basket mesh perforations; the perforations of the mesh in the third basket of the composting machine are smaller than the perforations of the second basket mesh perforations; and so on with the mesh perforations gradually decreasing in size from the first basket to the last basket. The drains 155 of the composting machine are configured to provide circulation back into the washing machine, rather than dumping the fluids to the sewer system. The first four modules or chambers have their drains 155 connected to a common pipe 157. A solids pump 159 is connected in line with the pipe 157 such that the input of the pump is connected to the pipe 157. The outlet of the pump is connected to a pipe 161 that opens into the interior of the fourth chamber 163. The outlet of the pipe 161 can be configured to discharge to the interior of the basket of the fourth chamber 163. Thus, the fluids collected by the drains of the first four chambers are circulated back into the fourth basket. A similar loop, with piping and pumps, is used on the remaining chambers, which are the fifth to the last chambers of the machine. This other loop circulates fluids from the last chambers back into the last basket. A blower 23 is provided as in the second washing machine of Fig. 1, but there is no ozone generator. The blower blows air into all of the chambers. (In Fig. 9, the blower connections have been shown only for the first few chambers for simplicity.) To compost the waste material, the waste material 165 is loaded into the first basket 153 of the composting machine 151. Warm water 167 (98-120 degrees Fahrenheit) and a small amount of alkali are also loaded into the first basket or chamber. The amount of water used is sufficient to create a congealed mass of waste. Too much water produces a thin slurry. For a Model 76032 Milnor continuous batch washing machine, the level of water should be about three inches from the lowermost portion of the basket, for a 110 pound load of waste material. The amount of alkali required raises the pH of the mixture in the first basket to about 8.0-8.5. This promotes the growth of bacteria. In addition, a food supply may be added to quicken biological growth. One type of food supply that can be used is dry or meal type dog food. Then, the first basket is rotated as described above. Additionally, the blower 23 injects air into the first basket. Thus, the waste material is agitated by the movement of the basket and by the blown in air, which initiates biological activity. After being agitated for a predetermined amount of time, such as 20 minutes, the machine 151 automatically stops rotating the first basket (and the other baskets as all of the baskets in the machine rotate in unison) and opens the drain 155 (and the drains of all of the other chambers) . The liquid from the basket passes through the first basket mesh and into the drain. The drain is then closed and the liquid is pumped into the fourth basket by the pump 159. The machine then automatically transfers the contents of the first basket 153 into the second basket 153A (and the contents of each basket into the next basket) . The agitation cycle is again started, wherein the baskets are rotated and air is injected into the baskets. Thus, the waste material is processed as it travels through the composting machine. When the material 169 exits the machine from the last basket, it is placed in a bin 171 where excess water can drain out through perforations 173 in the bottom of the bin. The processed material 169 can be used as composted material normally would be used. For example, the processed material can be mixed with soil in gardens. While processing the waste material in the washing machine, methane gas 175 will be generated. This gas is vacuumed out of the chambers by a suction pump 177 and sent to a storage tank 179. The tops of the chamber 25 in the washing machine are sealed by a hood 181, which prevents the methane gas from escaping. Once stored in the tank 179, the methane can be sold or used as a fuel source to heat water added to the washing machine through inputs 167. To use the methane to heat water, the methane is conveyed from the storage tank 179 to a burner 185 in a hot water heater 183, At the burner 185, the methane is combusted to produce heat. The heated water is then conveyed back to water inlets 167 through a pipe 187. A valve 189 contains the flow of water. Although the method of composting waste material has been described using an alkaline mixture, the waste material can be composed using an acidic mixture. An acid, such as acetic acid, carbonic acid or oxalic acid is added to the waste material in the washing machine. Sufficient acid is added to lower the pH to 2.3 to 4.0. During any one of the above described recycling processes, the waste water drained from the washing machine may become contaminated with heavy metals. To reduce the heavy metal content of the waste water, the waste water is exposed to ozone in treatment unit 201 (see Fig. 10) . The waste water is conveyed to the treatment unit 201 by the drain pipe 90 (or 111) . The treatment unit receives ozone from an ozone supply 24. The ozone bubbles up through the waste water, causing a reduction in the heavy metals. The waste water exits the treatment unit 201 by a pipe 203, where it is then conveyed into the drain system. From there the waste water can be treated at a sewage treatment facility. The treatment unit is periodically cleaned to remove the accumulated contaminants. One of the chambers of the first and second washing machines 13, 15 of Fig. 1 may be modified to remove insoluble contaminants that are not affected by processing operations in the preceding chambers. This modified chamber may be the last chamber, which is adjacent to the outlet 33. The chamber is modified by providing nested baskets. The other portions of the chamber are as described above. Referring to Fig. 11, the basket arrangement in the modified chamber has an inner basket 211 and an outer basket 213. The inner basket 211 is nested inside of the outer basket 213. The inner basket is coupled to the outer basket so that both rotate in unison. A gap 215 separates the inner basket and the outer basket. Each basket is provided with ribs 217 on its inner circumference. The gap may be several inches wide between the baskets and in any case is wider than the ribs 217 on the outer basket so as to allow any goods located in the gap to pass freely over the ribs. The size of the last chamber may be enlarged by 50% over the size of the preceding chambers in order that the inner basket 211 can accommodate a full load of goods. Both baskets are provided with wire mesh, which mesh provides the desired perforation size. The perforations of the inner basket mesh are larger than the perforations of the outer basket mesh. For example, when processing cellulose through the washing machine, the inner basket mesh has 30 wires per inch, while the outer basket mesh has 40 to 60 wires per inch. During operation, the goods that are being processed enter the inner basket 211 by the opening 35 from the preceding chamber. The baskets are rotated as described above so as to agitate the goods. In addition, air can be blown in. The goods, such as cellulose, pass through the mesh of the inner basket 211 and are retained in the gap 215 by the outer basket 213. This is because the goods are unable to pass through the mesh of the outer basket. The contaminants, which include husks, hair, undigested foods, etc. , are retained by the inner basket. The inner basket is provided with a non-perforated portion 219 which serves as the scoop for the outer basket. This portion 219 is located above the ribs, using the orientation of Fig. 11. Also above the ribs, opposite the scoop 219 is a non-perforated portion 221 which prevents goods located in the gap 215 from returning to the inner basket. The inner basket also has a perforated scoop 223. When it is time to transfer the goods out of the chamber, the baskets rotate a more complete revolution than is achieved during agitation operations. This moves the cellulose that is located inside the gap 215 to the scoop 219, wherein the cellulose is prevented from reentering the inner basket and is transferred out of the chamber. The cellulose exits by way of a ramp 77 (see Fig. 1) where it is deposited in a bin. The contaminants in the inner basket are moved onto the scoop 223 by the rotation, wherein the contaminants exit by way of a separate ramp where they are routed to a separate bin. The foregoing disclosure and the showings made in the drawings are merely illustrative of the principles of this invention and are not to be interpreted in a limiting sense.
