- the contents of the all the aforementioned cross-reference to related applications are incorporated herein in their entirety by this reference.
- the present invention pertains to systems and methods of recycling organic waste and utilizing the products thereof.
- the invention relates to a systems and methods of controllable separation between recyclable organic waste from a garbage disposal unit and graywater sewage from a kitchen sink, in a continuous manner.
- Household organic waste makes up a considerable percentage of total waste. This waste is typically thrown out with the rest of the garbage, requiring transport and space in dumps.
