ABSTRACT:
This disclosure is directed to a method and apparatus for recycling organic waste material into reusable compost. This is attained by shredding or grinding organic waste and mixing the ground waste into a homogeneous mass and conveying the homogeneous mass to a decomposition chamber where it is aerated with recirculating air to decompose into a reusable compost. The apparatus for carrying out the process includes a compact, self-contained housing having a component section and a decomposition chamber. The waste material is ground and mixed in the component section and then conveyed to the decomposition chamber by a conveyor which disperses the homogenous waste longitudinally and laterally within the decomposition chamber. A blower directs aerating air into the decomposition chamber and the air is recirculated back to the blower, where the recirculated air is mixed with a predetermined amount of incoming fresh air, and a portion of the recirculating air is exhausted to atmosphere, the exhausting air being filtered prior to being exhausted. Thereafter, the resulting compost is removed by an auger through a discharge opening of the decomposition chamber.
