NOVELTY - The anaerobic digester assembly comprises: an outer container (12); a primary anaerobic digester vessel (14) positioned within the outer container; secondary gas collection vessels (16) positioned within the outer container; an isolator positioned both within the outer container and between the primary anaerobic digester vessel and the secondary gas collection vessels; a containment regulating insulation positioned with the outer container; a water heater associated with the secondary gas collection vessels; and a methane generator associated with the secondary gas collection vessels.    USE - The anaerobic digester assembly is useful for converting waste to resource.    ADVANTAGE - The eco-friendly anaerobic digester assembly is inexpensive, portable and modular, has enhanced mobility and scalability, and reduces air and water pollution.    DETAILED DESCRIPTION - The anaerobic digester assembly comprises: an outer container (12); a primary anaerobic digester vessel (14) positioned within the outer container; secondary gas collection vessels (16) positioned within the outer container; an isolator positioned both within the outer container and between the primary anaerobic digester vessel and the secondary gas collection vessels; a containment regulating insulation positioned with the outer container; a water heater associated with the secondary gas collection vessels; a methane generator associated with the secondary gas collection vessels; an input vessel including a pre-anaerobically digested animal excrement and partially anaerobically digested animal excrement; an output vessel including anaerobically digested animal excrement; an input valve (18) in fluid communication with the input vessel and the primary anaerobic digester vessel; and an output valve (20) in fluid communication with the output vessel and the primary anaerobic digester vessel.
