NOVELTY - Bioconversion (m1) of organic waste material in synthetic biofuel production processes to increase energy efficiency involves providing at least one inlet to bioconversion tank having active biomass, where each inlet is for organic material/aqueous stream having the material; providing processor to receive and store information automatically/manually input on status of chemical and biological oxygen demand of the biomass, and oxygen provision capability of organic material that fed into tank; and providing stream carrying combustible gases from the biomass.    USE - For bioconversion of organic waste material (such as at least one of whole stillage, thin stillage and glycerin) in synthetic biofuel production processes to increase energy efficiency (claimed). For the conversion of waste and contaminants into an energy source (e.g. methane); and for extracting energy 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.    ADVANTAGE - The bioconversion method and system provides advantage that the residual products are converted to fuels that can support the primary synthetic process, reduce or eliminate the overall external input of energy into the system, and thus produce a system with a much better efficiency and potentially produce an additional energy product for sale.    DETAILED DESCRIPTION - Bioconversion (m1) of organic waste material in synthetic biofuel production processes to increase energy efficiency, involves providing a tank for bioconversion of organic waste material, at least some of which is derived from a synthetic fuel manufacturing process; providing at least one inlet to the tank, individual inlets may be for organic material or an aqueous stream containing organic material; providing a processor that receives and stores information automatically or manually input on the status of chemical oxygen demand (COD) and/or biological oxygen demand (BOD) of the biomass, and the oxygen provision capability of an organic material that is fed into the tank through any inlet; and providing a stream carrying combustible gases from the biomass. The tank comprises an active biomass containing at least one bacteria that decomposes organic material. The processor exercises control over a mass flow control system which feeds the at least one organic material through an inlet, and directs mass flow at a rate based at least in part upon the status of chemical oxygen demand in the bioconversion tank as recognized by the processor from received information. The stream provides at least some of the energy input in the performance of the synthetic fuel manufacturing process. INDEPENDENT CLAIMS are included for the following:    (1) an organic bioconversion system (s1) for providing energy to a synthetic biofuel manufacturing process comprising a) at least a first organic material storage tank for a first organic material; b) an aqueous stream input source; c) a bioconversion tank having a controlled input connection from a) and a controlled input connection from b), and containing an active biomass that comprises bacteria capable of decomposing the first organic material from the first organic material storage tank; d) a processor that controls the input connections from a) and from b); e) a sensing system that determines the chemical oxygen demand of the active biomass in the bioconversion tank and controls flow of at least the first organic material through the input connection from a) to provide oxygen from the first organic material is provided to the active biomass in the bioconversion tank at a rate to support health of the bacteria in the bioconversion tank; f) an aqueous stream outlet from the bioconversion tank; and g) a gaseous stream outlet from the bioconversion tank that is stored and then fed or directly fed to an oxidizing system that produces energy for the synthetic biofuel manufacturing process having a nutrient sensing system that detects levels of nutrients in at least one of the biomass in the bioconversion tank and an aqueous stream passing into or through the aqueous stream output and information from the nutrient sensing system to the processor, and the processor determines levels of nutrients that should be provided to the active biomass in the bioconversion tank. The processor may contain software that determines levels of nutrients that should be provided to the active biomass in the bioconversion tank from sensed data from the nutrient sensing system and controls flow of nutrients into the bioconversion tank to provide nutrients in a quantity determined by the software, where nutrients sensed may comprise at least one nutrient selected from the class consisting of available nitrogen and available phosphorus, and the gaseous stream outlet may be connected to a gas stream separation system that can increase the concentration of methane in a first concentrated stream and can increase the concentration of carbon dioxide in a second concentrated stream; and    (2) reduction (m2) of total external energy requirements input into the operation of a system requiring energy input involving providing organic materials to a bioconversion process; performing a bioconversion process on the organic materials; producing combustible volatile organic material from the bioconversion process; and providing input energy to the operation of the system by oxidizing the combustible volatile organic material from the bioconversion process. The organic material may comprise at least 10 wt.% water during the bioconversion process and at least some water is added with the organic materials provided to provide a total water content during the bioconversion, and optionally water is added with the organic material at an average rate over time, where over periods of time the average rate water added with the organic material may be decreased by recirculation of residual water from the bioconversion process.
