NOVELTY - High-nitrogen loading via anaerobic digestion, comprises: feeding a substrate comprising a waste material having anaerobically biodegradable components into an anaerobic digester device, feeding a co-substrate into the anaerobic digester device with the substrate; and co-digesting the substrate and the co-substrate in the digester device to produce a biomass, a biogas, and a waste product. The anaerobic digestion comprises monitoring temperature, mixing of organic waste, and adjusting pH, and ammonia levels.    USE - The method is useful for loading high-nitrogen for ammonia processing via anaerobic digestion for producing a biomass, a biogas, a waste product (claimed) and ammonium based fertilizers, where the biogas is methane gas. No biological data given.    ADVANTAGE - The method is capable of simply loading the high-nitrogen for ammonia processing via anaerobic digestion with improved stability in an economical manner, and improves the yield of biogas.    DETAILED DESCRIPTION - High-nitrogen loading via anaerobic digestion, comprises: feeding a substrate comprising a waste material having anaerobically biodegradable components into an anaerobic digester device, feeding a co-substrate into the anaerobic digester device with the substrate; and co-digesting the substrate and the co-substrate in the anaerobic digester device to produce a biomass, a biogas, and a waste product. The anaerobic digester device comprises a single stage anaerobic digester or a multi-stage anaerobic digester. The anaerobic digestion comprises monitoring temperature, mixing of organic waste, and adjusting pH, and ammonia levels within a heated vessel of the anaerobic digester device. The nitrogen in the waste product and high nitrogen organic and/or inorganic supplements is converted to a material comprising ammonia. INDEPENDENT CLAIMS are included for:    (1) a system for high-nitrogen loading via anaerobic digestion, comprising a substrate comprising a waste material having anaerobically biodegradable components fed into an anaerobic digester device; and    (2) an apparatus for high-nitrogen loading via anaerobic digestion, comprising an anaerobic digester device, a substrate comprising a waste material having anaerobically biodegradable components fed into the anaerobic digester device, and a co-substrate fed into the anaerobic digester device with the substrate, where the substrate and the co-substrate co-digested in the anaerobic digester device to produce a biomass, a biogas, and a waste product.
