TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: In the method (m1), there are at least two storage tanks for organic material, a first and second storage tank for first and second organic material. The first and second organic materials have different chemical oxygen provision capabilities from each other. The processor receives and stores information on the respective chemical oxygen provision capabilities of the first and second organic material; and the processor feeds the first and second organic material into the bioconversion tank at a rate based at least in part upon the status of chemical oxygen demand in the bioconversion tank, the chemical oxygen provision capability of the first and second organic material as recognized by the processor and a filter may be present between the active biomass in the bioconversion tank and the treated aqueous outlet. The method (m1) removes an energy depleted aqueous stream from the bioconversion tank through an aqueous stream outlet and a biogas stream is removed from the bioconversion tank through a gas venting outlet, the biogas stream comprising primarily methane and carbon dioxide is removed from the bioconversion tank. At least one of the active biomass and energy depleted aqueous stream are automatically tested for active biomass nutrient content and testing information is provided to the processor or where when testing for pH indicates that the pH level in the treatment tank is not within a desired range stored in the processor which directs a feed system for a pH active material selected from the at least one of a base, acid or buffer to input pH active material into the bioconversion tank to bring the pH level in the tank within the desired range. When testing for active biomass nutrient content indicates that the nutrient level in the bioconversion tank is not within a desired range stored in the processor, the processor directs a nutrient feed system to input nutrient material into the bioconversion tank to bring nutrient level in the tank within the desired range, where testing may be performed for at least one of available nitrogen and available phosphorus, and the results of such testing are used by the processor to determine how much nutrient is to be added to the bioconversion tank to specifically adjust at least one of nitrogen and phosphorus content in the treatment tank. In the method (m1), where mass flow through the system is at least in part automatically controlled by sensing at least one of weight/volume/density/flow, viscosity/moisture content/FOG (fats, oils, and greases), pH and alkalinity monitoring, temperature, BOD/COD/volatile acid concentration/protein concentration/FOG concentration/carbohydrate concentration/sugar concentration/methane potential, particle size, detection of contaminants and alarm, and general water quality parameters such as conductivity and oxidation reduction potential (ORP); and automatically providing a presumed appropriate response to the sensing according to at least one of a lookup table, hardware response and software response, or the bioconverter system is sensed and automatically responded to by sensing at least one of contaminant alarm, solids concentration monitoring and control, BOD and COD monitoring and control, surface tension/foam detection monitoring and alarm, FOG monitoring and alarm, dissolved gas monitoring and alarm, volatile acids monitoring and alarm, detection and control of specific bacteria concentration/activity, and automatically responding to it. The method (m2) involves at least one process selected from:(1) process (a): performing a process for the manufacture of the synthetic biofuel and inputting energy to perform the process; collecting organic waste material from the process for manufacture of the synthetic biofuel; providing collected waste material to a bioconversion process; providing combustible volatile organic material from the bioconversion process; and providing input energy to the process for the manufacture of the synthetic biofuel by oxidizing the combustible volatile organic material from the bioconversion process; and(2) process (b): providing the system (s1).Preferred System: In the bioconversion system (s1), there are sensing systems for at least one other sensible condition may be selected from pH of the biomass in the bioconversion tank, pH of the aqueous stream from the bioconversion tank, concentration of a specific gas component in the gaseous stream from the bioconversion tank and gas pressure within the bioconversion tank; and the processor may contain software that controls rate flows of materials into the bioconversion tank in response to an indication from sensed data that the rate flows of specific materials into the bioconversion tank, and the software may be responsive to the sensed data in controlling mass input into the bioconversion tank.
