Solids separator for a composting system

A composting system for separating solid waste from liquid waste in a stream of waste passing through a sink drain, the composting system comprising:

• a P-trap fluidly coupled to the sink drain downstream of the sink drain;
• a solids separator fluidly coupled to the P-trap downstream of the P-trap, the solids separator defining a liquids outlet for passing the liquid waste and a solids outlet for passing the solid waste;
• and
• a composting bin fluidly coupled to the solids outlet, the composting bin defining a mixing chamber for receiving the solid waste, wherein the solids separator comprises:
• a housing defining a waste inlet for receiving the stream of waste, the liquids outlet for passing the liquid waste, and the solids outlet for passing the solid waste;
• a separator belt positioned within the housing and extending between the liquids outlet and the solids outlet, the separator belt defining a plurality of apertures through which the liquid waste passes through the separator belt and into the liquids outlet;
• a drive cylinder rotatably mounted within the housing and being selectively rotated to drive the separator belt such that a top surface of the belt is moved toward the solids outlet along with the solid waste that is extracted from the stream of waste;
• and
• a plurality of cleaning pins that are mounted on at least one of the drive cylinder and the tensioning cylinder, the plurality of cleaning pins extending through the plurality of apertures in the separator belt to clean the separator belt.

• and
• a wiper arm positioned adjacent to and in contact with a bottom surface of the separator belt, the wiper arm being configured to remove the solid waste from the separator belt.
