NOVELTY - Processing (M1) organic materials involves: combining organic liquid fraction which is derived at least in part from microbial digestion of an organic waste, with microorganisms; digesting the organic liquid fraction in reactor; separating a liquid component from digested materials in the reactor; combining the liquid component with a protein source and an enzyme; and proteolytically digesting the protein source to form a nitrogen-enriched liquid component.    USE - For processing organic materials to obtain nutrient-rich components and biogas or for enriching organic materials (all claimed); for producing organic fertilizer in agricultural and industrial uses; for assisting in the growth of agricultural crops, residential plants, and landscaping flora without the need for synthetic or petroleum-based fertilizers.    ADVANTAGE - The method yield biogas that has various uses as a clean energy source of heat or electricity; carefully weighing input organic material so as to accurately proportion various stages of mixing operations and accurately predict content of the nutrient enriched product fractions.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a system (s1) for processing organic materials comprising: a comminution device fluidly coupled to a biology reservoir; weighing device configured to weigh an amount of organic materials provided 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) a system (s2) for enriching organic materials, comprising: a pasteurizer comprising an inlet port, where the inlet port is configured to receive an organic liquid fraction; proteolytic digester fluidly coupled to the pasteurizer; concentrating device fluidly coupled to the proteolytic digester; and liquid separation device fluidly coupled to the concentrating device.
