ABSTRACT:
An apparatus and method for treating waste products having a bioreducing unit, means for scrubbing air and gases exhausted from the unit and for recovering byproducts formed in the bioreduction step, and means for dehumidifying the scrubbed air. Fly larvae which hatch from eggs added to the waste product in the bioreducing unit aerate the waste product and thus accelerate the bioreduction and removal of moisture. The fly larvae and the bioreduced manure are then separated on a perforated screen belt by utilizing the negative reaction of the larvae to light.
