Abstract

A system for separating waste by type and collecting the separated wastes, preserving the integrity of the separation during the collection and consolidation, including a multi-compartment inside container for the initial separation, an outside container that interfaces with the inside container so that the separated contents of the latter can be dumped into the former, a mobile collection unit that transfers the separated wastes from the outside container to a plurality of bins, again preserving the separation, and transports the waste to a distribution facility. The volume of the separated waste is reduced by the collection vehicle as it is dumped through hatches on the top of the vehicle into chutes that lead to the appropriate bin for that type of waste. The collection vehicle grips, lifts and inverts the outside container, made up of three subcontainers, and then separates them so that each can be positioned over and aligned with a different hatch on the top of the vehicle.

Claims

1. Apparatus for collecting wastes sorted by type, said apparatus for use with a container having a plurality of compartments, each of said compartments holding only one type of said waste, said apparatus comprising:

means carried by said housing for moving said container to said hatch so that said containers can be emptied into said hatch; and

means carried within said housing for distributing said wastes emptied through said at least one hatch into said plurality of bins so that said one type of said waste from said each compartment is received by said only one bin of said plurality of bins corresponding to said each compartment whereby said each bin of said plurality of bins holds said only one type of said waste.

2. The apparatus as recited in claim 1, further comprising means carried in said interior of said housing for reducing the volume said wastes.

3. The apparatus as recited in claim 1, wherein said container further comprises more than one subcontainer, each subcontainer of said more than one subcontainer being separable from any other subcontainers of said more than one subcontainer, and said at least one hatch further comprises only one hatch for each subcontainer of said more than one subcontainer.

4. The apparatus as recited in claim 1, wherein said housing includes a top and said moving means moves said container to said top of said housing.

5. The apparatus as recited in claim 1, wherein said housing includes a top and said moving means moves said container to said top of said housing, said moving means inverting said container.

6. The apparatus as recited in claim 1, wherein said moving means inverts said container.

7. The apparatus as recited in claim 1, wherein said housing has a top, said container has an initial position, and said moving means further comprises:

means for rotating said container approximately 90 degrees from said initial position; and

means for lifting said container to said top of said housing, said lifting means rotating said container approximately 90 degrees so that said container is inverted from said initial position.

8. The apparatus as recited in claim 1, wherein said distributing means further comprises a plurality of chutes carried by said housing, each chute of said plurality of chutes leading from said at least one hatch to one bin of said plurality of bins, said each chute conducting waste from each compartment of said plurality of compartments of said container to said one bin of said plurality of bins.

9. Apparatus for collecting wastes sorted by type, said apparatus for use with a container comprising more than one subcontainer, each subcontainer being separable from any other subcontainers of said more than one subcontainer, said apparatus comprising:

a housing having an interior, a top and more than one hatch on said top for providing access to said interior of said housing, each hatch of said more than one hatch corresponding to said only one subcontainer of said more than one subcontainer;

a plurality of bins carried in said interior of said housing for receiving said waste;

means carried by said housing for lifting said container to said top of said housing and inverting said container;

means carried by said housing for moving said more than one subcontainers so that each subcontainer can be placed over only one hatch and aligning said each subcontainer with said each hatch; and

means carried within said housing for distributing waste emptied through said more than one hatch into said plurality of bins.

10. The apparatus as recited in claim 9, wherein said lifting and inverting means further comprising means for covering said container so that waste in said container does not fall out when said container is inverted, said covering means uncovering said more than one subcontainers when said more than one subcontainers are aligned with said more than one hatch.

11. The apparatus as recited in claim 9, wherein said distributing means further comprises means for processing waste passing from said more than one subcontainer to said plurality of bins so that the volume of said waste in said plurality of bins is less than the volume of said waste when said waste was in said more than one container.

12. The apparatus as recited in claim 9, wherein said waste further comprises shredable waste and crushable waste and said distributing means further comprises shredders for shredding said shredable waste and crushers for crushing said crushable waste, said shredable waste being shredded by said shredders and said crushable waste being crushed by said crushers before said waste passes to said plurality of bins.

13. The apparatus as recited in claim 9, wherein said container has an initial position and wherein said lifting and inverting means further comprises:

means for rotating said container approximately 90 degrees from said initial means; and

means for lifting said container after said rotating means rotates said container and rotating said container until said container is inverted.

14. The apparatus as recited in claim 9, wherein said housing further comprises a floor and a plurality of openings in said housing, one of said plurality of openings for each bin of said plurality of bins, said plurality of bins being supported by said floor, said floor including means for sliding said each bin of said plurality of bins through said one opening of said plurality of openings.

15. The apparatus as recited in claim 9, wherein said distributing means further comprises a plurality of chutes carried by said housing, each chute of said plurality of chutes leading from said more than one hatch to one bin of said plurality of bins, said each chute conducting waste from said more than one hatch to one bin of said plurality of bins.

16. Apparatus for collecting wastes sorted into a plurality of types, said apparatus comprising:

a container comprising a plurality of compartments, each compartment designated to hold only one type of said plurality of types;

a housing with an interior, a floor, a top, a hatch carried by said top of said housing, and a plurality of openings in said housing;

said chutes arranged so that each compartment of said container is aligned with only one of said chutes when said container is aligned with said hatch by said lifting means.

17. The apparatus as recited in claim 16, further comprising means for processing said waste to reduce volume of said waste before said waste enters said plurality bins, said processing means being carried within said chutes said waste is processed as it falls toward said bins from said hatch.
