    摘要： A process and apparatus for reducing the volume and mass of solid waste (A) by initially subjecting the solid waste to a digestive enzymatic solution (20) agitated by fluid jets (28) under conditions which convert substrate (12) into a liquid waste which is discharged through a conventional sewage system (30). Non-biodegradable plastic shells (10) may be collected in a strainer basket (24) to be removed for further solid waste treatment such as shredding and the like.

    摘要： An apparatus separates a substantially metallic portion from a substantially non-metallic portion of constituent components of at least one electrical product, comprising a plurality of crushing machines, such as a first crushing machine, a second crushing machine, and a third crushing machine and a separating machine. The first crushing machine crushes the at least one electrical product to create at least one crushed electrical product. The first crushing machine has a first screen affixed thereto to regulate a first flow of the at least one first crushed electrical product from the first crushing machine. The second crushing machine crushes the at least one first crushed electrical product to create at least one second crushed electrical product. The second crushing machine has a second screen affixed thereto to regulate a second flow of the at least one second crushed electrical product from the second crushing machine. The third crushing machine crushes the at least one third crushed electrical product to create at least one third crushed electrical product. The third crushing machine has a third screen affixed thereto to regulate a third flow of the at least one third crushed electrical product from the third crushing machine. The at least one separating machine receives the at least one third crushed electrical product from the third crushing machine to separate the metallic portions from the non-metallic portions of the at least one electrical product. A plurality of air separators may be used to remove non-metallic light weight materials from the crushed electronic products to deposit in a collection bin and to return the portions of the light weight material that comprise metallic material to the stream of crushed material. A plurality of conveyors may also be used to transport the at least one first, second, and thrid crushed electrical products to and from the first crushing machine, the second crushing machine, the third crushing machine, and the at least one separating machine.

    摘要： Preferred processes to separate metallic and non-metallic constituent components of at least one electronic product are generally comprised of the following steps: (a) repeatedly crushing the at least one electronic product to create a plurality of crushed electronic components; (b) repeatedly screening the plurality of crushed electronic components to ensure that the plurality of crushed electronic components substantially conform to a specific size; and (c) separating the plurality of crushed electronic components after steps (a) and (b) into non-metallic constituent components and metallic constituent components by weight. In addition, before step (a), the at least one electronic product must be provided or otherwise transported to crushing machines to perform step (a). Likewise, the crushed electronic components must be transported from one crushing machine to another crushing machine and to the separating apparatus to perform step (c). At least three crushing machines are generally used, so that the at least one electronic product are generally crushed at least three times (and transported between the crushing machines). The crushed electronic products are also periodically screened, such as after each crushing step to limit the size of the crushed materials in the stream of crushed materials being evaluated. Lightweight material is also removed from the stream of crushed materials by at least one air separator. Portions of the light weight material that comprise metallic material are returned to the stream of crushed material. Portions of lightweight material substantially comprised of non-metallic materials (i.e., dust) is transported to a collection apparatus. The products can be shredded before step (a).

    摘要： An apparatus and method provides a way of collecting, treating, processing and recycling a variety of hazardous waste material and transforming such materials into a stable, granular nonhazardous substance suitable for safe disposal. The apparatus disclosed combines a variety of separate mechanisms and devices such as vibrating screens, motorized crushers, conveyor systems, and electric or fuel powered motors into a single integrated machine. Chemical additives can be used to treat the waste and bond to any heavy, leachable materials such as lead, copper, cadmium, zinc and other metals and thus lower their leaching characteristics to acceptable nonhazardous levels in compliance with Environmental Protection Agency standards. A concrete additive is added to the waste and the mixture is ground into a manageable substance of uniform texture and consistency.
