NOVELTY - Method for processing organic material, involves forming a slurry from components comprising liquid and organic material, combining the slurry with microorganisms to form a biomass, anaerobically digesting the organic material in the biomass, and at least partially separating liquid components from the digested biomass, where not greater than 0.02 m of methane per kilogram of organic material is produced during the method.    USE - The method is useful for processing organic material to produce nutrient rich materials which are used in agricultural purposes.    ADVANTAGE - The method is cost-effective.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) system for processing organic materials comprising comminution device fluidly coupled to a biology reservoir, first heat exchanger thermally coupled to the biology reservoir, dewatering device fluidly coupled to the biology reservoir, where the dewatering device is configured to at least partially separate liquid components from a composition received from the biology reservoir, solids reservoir fluidly coupled to the dewatering device and configured to receive solid components from the dewatering device, liquid reservoir fluidly coupled to the dewatering device and configured to receive liquid components from the dewatering device, where the liquid reservoir is fluidly coupled to the biology reservoir and configured to return liquid components to the biology reservoir, and housing having a closed interior portion, where the closed interior portion comprises at least the biology reservoir, the solids reservoir and the liquid reservoir; and    (2) non-transitory computer-readable medium having instruction (stored) for execution by a processor to perform method for processing organic material, which involves forming a slurry from components comprising water and organic material, combining the slurry with mesophilic microorganisms to form a biomass, anaerobically digesting the organic material in the biomass, and at least partially separating liquid components from the digested biomass, where not greater than 0.02 m of methane per kilogram of organic material is produced during the method.
