A method, system, apparatus and program extracts energy from organic residual materials produced by the manufacturing of biofuels. Energy is extracted from the biofuels residuals using anaerobic bioconversion to produce a fuel for use in the manufacturing process for producing synthetic biofuel or as an additional energy product for sale comprises: providing at least one bioconversion tank for conversion of organic waste material, the bioconversion tank containing an active biomass comprising at least one bacteria that decomposes organic material; providing at least one inlet to the bioconversion for organic material; a processor that receives and stores information on: the status of chemical oxygen demand of the active biomass; and the oxygen provision capability of any organic material that can be fed into the bioconversion tank through an inlet; a mass flow control system controlled by the processor which feeds at least one organic material through an inlet at a rate based at least in part upon the status of chemical oxygen demand in the bioconversion tank as recognized by the processor.
