Abstract

A composting system for decomposing waste material includes a composting bay adapted to receive the waste material. A transport member extends into the composting bay and is adapted to receive the waste material thereon. The transport member is moveable with respect to the bay for transporting waste material along the bay. The composting system further includes a fluid distribution system having at least one fluid injection member adapted to extend into the waste material. The at least one fluid injection member is moveably attachable to the bay such that the at least one fluid injection member is moveable with the waste material along a portion of the bay. The at least one fluid injection member has at least one opening for introducing fluid into the waste material. A method for decomposing waste material is also disclosed.

Claims

1. A composting system for decomposing waste material, the composting system comprising:

a composting bay adapted to receive the waste material;

a transport member having at least a portion disposed in the composting bay and adapted to receive the waste material thereon, the transport member being moveable with respect to the bay for transporting the waste material along the bay; and

a fluid distribution system having at least one fluid injection member adapted to extend into the waste material, the at least one fluid injection member being moveable with respect to the bay such that the at least one fluid injection member is moveable with the waste material along a portion of the bay, the at least one fluid injection member having at least one opening for introducing fluid into the waste material.

2. The composting system of claim 1 wherein the transport member comprises a nylon net.

3. The composting system of claim 1 wherein the fluid distribution system further comprises an air compressor in communication with the at least one fluid injection member for supplying air to the at least one fluid injection member.

4. The composting system of claim 1 wherein the fluid distribution system includes a plurality of fluid distribution cells moveable with respect to the bay such that the cells are moveable with the waste material along a portion of the bay, each cell including a plurality of fluid injection members adapted to extend into the waste material, and each of the fluid injection members including a plurality of openings for injecting fluid into the waste material.

5. The composting system of claim 4 wherein the fluid distribution system further comprises a steam generating unit in communication with at least one of the fluid injection members for supplying steam to the at least one fluid injection member.

6. The composting system of claim 1 further comprising a vapor treatment system for treating air that collects in the bay, the vapor treatment system including an intake in communication with the bay, and a steam tube for introducing steam into the air.

7. A composting system for decomposing waste material, the composting system comprising;

an enclosed composting bay having a bottom, a roof enclosure and first and second ends;

a transport member disposed proximate the bottom of the bay and adapted to receive the waste material thereon, the transport member being moveable with respect to the bay for transporting waste material between the ends of the bay;

a guide system attached to the bay proximate the roof enclosure;

a plurality of fluid distribution cells movably attachable to the guide system such that the cells are movable with the waste material along a portion of the bay, each of the cells having a plurality of fluid injection members adapted to extend into the waste material for injecting fluid into the waste material.

8. The composting system of claim 7 wherein at least one of the fluid injection members comprises a rubber tube.

9. The composting system of claim 7 wherein at least one of the fluid injection members comprises a steel tube.

10. A method of decomposing waste material, the method comprising:

positioning the waste material in a composting system having a moveable transport member and a moveable fluid injection member such that the waste material surrounds a portion of the fluid injection member;

moving the transport member to thereby move the waste material within the composting system;

moving the fluid injection member such that the fluid injection member moves with the waste material; and

introducing fluid into the waste material from the fluid injection member.

11. The method of claim 10 wherein moving the fluid injection member occurs as a result of moving the transport member.

12. The method of claim 10 wherein introducing fluid comprises injecting air into the waste material.

13. The method of claim 10 wherein introducing fluid comprises injecting steam into the waste material.

14. The method of claim 10 wherein introducing fluid comprises injecting heated water into the waste material.

15. The method of claim 10 positioning the waste material comprises positioning the waste material in an enclosed bay of the composting system.

16. The method of claim 15 further comprising treating air that collects in the bay by introducing steam into the air.

17. A method of decomposing waste material, the method comprising:

providing a composting system having an enclosed composting bay and a plurality of fluid injection members moveably attached to the bay and adapted to extend into the waste material, the bay having first and second ends;

introducing the waste material into the bay proximate the first end such that the waste material surrounds a portion of each of the fluid injection members;

moving the waste material between the first and second ends;

moving the fluid injection members such that the fluid injection members move with the waste material; and

introducing fluid into the waste material from the fluid injection members.

18. The method of claim 17 wherein introducing fluid comprises selectively injecting fluid into the waste material from the fluid injection members.

19. The method of claim 17 wherein introducing fluid comprises injecting air into the waste material.

20. The method of claim 17 wherein introducing fluid comprises injecting steam into the waste material.

21. The method of claim 17 wherein introducing fluid comprises injecting heated water into the waste material.
