  • Patent number: 5971303
    Abstract: An apparatus for routing, treating and recycling refuse includes a first valve connected between the drain and the main sewer line for receiving water and refuse flowing through the drain. A compost pile and water separation tank are connected to a second valve which is connected to receive water and refuse from the first valve. The first valve operates between a first position directing the water and refuse received thereby to the main sewer line and a second position directing the water and refuse received thereby to the second valve. The second valve operates between a first position directing the water and refuse received from the first valve to the compost pile and a second position for directing the water and refuse received from the first valve to the separation tank. The water received by the separation tank is stored in a water storage tank for recycling and later use while the refuse directed to the compost pile and separation tank is collected for later use.
