Process for processing organic waste
A process for producing dried pieces of organic waste by reducing raw organic waste to pieces and drying the raw organic waste to a moisture content at which it is generally free of odors caused by microbial activity.
1. A process for producing a biodegradable solid of organic waste comprising:
providing a receiving module removably mounted to a processing module, with the receiving module having a perforated liner;
collecting organic waste by placing the organic waste in the perforated liner of the receiving module when the receiving module is removed from the processing module;
reducing the organic waste to pieces before the organic waste is dried by operating a reducing element located in the perforated liner of the receiving module while the receiving module is mounted to the processing module;
transferring the pieces from the receiving module to the processing module while the receiving module is mounted to the processing module by passing the pieces through the perforated liner;
mixing the pieces with a biodegradable binder to form a mixture; and
forming a unitary biodegradable solid from the mixture by drying the mixture wherein the reduced organic waste pieces are converted to a unitary biodegradable solid.
2. The process of claim 1 wherein the transferring further comprises the pieces traveling from the perforated liner of the receiving module through at least one passageway to the processing module.
3. The process of claim 2 wherein the transferring further comprises the pieces traveling to a form in the processing module.
4. The process of claim 1 wherein the transferring the pieces further comprises flushing the pieces through the perforated liner.
5. The process of claim 1 wherein forming the mixture comprises mixing the pieces with water.
6. The process of claim 1 wherein forming the unitary biodegradable solid comprises forming the mixture into a predetermined shape.
7. The process of claim 1 wherein the drying further comprises heating the mixture.
8. The process of claim 7 further comprising removing liquid water from the mixture.
9. The process of claim 8 wherein the liquid water is re-used in a subsequent process for producing a unitary biodegradable solid.
10. The process of claim 7 further comprising capturing water vapor emitted while drying the mixture.
11. The process of claim 10 further comprising converting the captured water vapor to liquid water.
12. The process of claim 11 wherein the liquid water is re-used in a subsequent process for producing a unitary biodegradable solid.
13. The process of claim 8 wherein the water or biodegradable binder in the mixture is obtained from the organic waste.
14. The process of claim 13 wherein the biodegradable binder is a carbohydrate.
15. The process of claim 14 wherein the biodegradable binder is activated by heating.
16. The process of claim 1 wherein the biodegradable binder is a carbohydrate.
17. The process of claim 16 wherein the biodegradable binder is activated by the heating.
18. The process of claim 1 wherein the drying comprises drying the mixture to a moisture content at which the mixture is free of odors caused by microbial activity.
