NOVELTY - Treating organic waste for anaerobic digestion of biogenic-organic substances, involves preparing a waste-slurry from the organic waste; transferring the waste-slurry to a paddle pulper/finisher (7); processing the waste-slurry in the paddle pulper/finisher, to reduce particle size of solids in the waste slurry and form a finisher-slurry in the paddle pulper/finisher, and to separate a pulp (8) and a pomace (9) from the finisher-slurry in the paddle pulper/finisher; transferring the pulp to an anaerobic digester; and digesting the pulp in the anaerobic digester.    USE - For treating organic waste for anaerobic digestion of biogenic-organic substances, and the treated waste is fed to an anaerobic digester e.g. wet anaerobic digester, for producing soil amendments, methane gas (claimed) and fertilizer; and particularly useful for treating food wastes (e.g. bottle caps, plastic eating utensils, food wrappers, plastic wrappers, rubber bands, broken glass grit, rocks and seeds) and other biologically-degradable wastes, found at restaurants, institutional kitchens (e.g schools, retirement homes, prisons) and special food processing facilities such as farms, grocery stores and food-canning or food-freezing factories.    ADVANTAGE - The method uses paddle pulper/finisher to treat presorted food wastes and similar biologically degradable wastes via anaerobic digestion. Thus, the organic wastes are treated at minimum cost in equipment, at a plant requiring minimum real estate, and with maximum generation of methane gas, fertilizer and soil amendments. The paddle pulper/finisher equipment is low in initial cost; is easily and inexpensively maintained; is easily and safely operated; and requires low power requirements, minimizing increasing costs of electricity and energy. The machinery/equipment can easily and efficiently remove non-digestible material from the feed stock. The treated/processed waste can be fed to the anaerobic digester, without additional modifications to existing anaerobic digester.    DETAILED DESCRIPTION - Treating organic waste for anaerobic digestion of biogenic-organic substances, involves preparing a waste-slurry from the organic waste; transferring the waste-slurry to a paddle pulper/finisher (7); processing the waste-slurry in the paddle pulper/finisher, to reduce particle size of solids in the waste slurry and form a finisher-slurry in the paddle pulper/finisher, and to separate a pulp (8) and a pomace (9) from the finisher-slurry in the paddle pulper/finisher; transferring the pulp to an anaerobic digester; and digesting the pulp in the anaerobic digester for producing methane gas and soil amendments. The paddle pulper/finisher has a cylindrical screen body (10) formed with small discreetly-spaced screen openings (11) throughout the body between inlet and outlet end openings (12, 13); and at least one elongated paddle (14) extending a length portion of the cylindrical screen body carried on a rotating paddle shaft (15). The rotating paddle shaft has an axis (16) concentric with a longitudinal axis (17) of the cylindrical screen body. The paddle has a paddle edge (18) positioned near the cylindrical screen body. The paddle has a pitch (19) for propelling the finisher-slurry toward the outlet opening, while pressuring the finisher-slurry radially outwardly and against the cylindrical screen body, to reduce the particle size of the finisher-slurry via action of the paddle. The extruded pulp exits through the screen openings. The extruded pomace exits the cylindrical screen body through the outlet opening. The organic waste is slurried by dumping the organic waste in a slurry tank, adding a liquid and mechanically mixing the organic waste and liquid until a consistent slurry is obtained. The slurry from the slurry tank is processed by forming a macerator-slurry in an inline macerator unit, which removes heavy solids and cuts solids into smaller sizes that can be transferred by a slurry pump.
