Abstract
A method, system, apparatus and program for effecting the decomposition of organic waste material comprises: providing a treatment tank for decomposition of organic waste material, the treatment tank containing an active biomass comprising at least one bacteria that decomposes organic material; providing at least two inlets to the treatment tank, a first inlet comprising an inlet for organic material and a second inlet comprising an inlet for an aqueous stream; a processor that receives and stores information on: the status of chemical oxygen demand of the active biomass; and the oxygen provision capability of a first organic material that can be fed into the treatment tank through the first inlet; a mass flow control system controlled by the processor which feeds the at least one organic material through the first inlet at a rate based at least in part upon the status of chemical oxygen demand in the treatment tank as recognized by the processor.
