NOVELTY - The waste processing system comprises a pulper (310) for removing non-biodegradable material from the waste and pulping the biodegradable material, an anaerobic membrane bioreactor comprising microorganisms for producing biogas and anaerobic effluent from the pulped biodegradable material (316), and a membrane for retaining the microorganisms and a solid portion of the biodegradable material in the anaerobic membrane bioreactor. The removal of non-biodegradable material in the pulper protects the membrane of the anaerobic membrane bioreactor.    USE - The system is useful for processing waste such as food waste, fat, oil and grease comprising a biodegradable material (all claimed) to produce fertilizer and/or energy.    ADVANTAGE - The system is capable of efficiently processing the waste comprising a biodegradable material thus economically providing a source of affordable fertilizer for local farmers in an environmental friendly manner, allows to transport the wastes to the distribution facility on the return leg of scheduled deliveries to the retailers without incurring additional transport costs, provides waste savings, energy savings, public relations benefits, environmental, calculations, networked system management, improved operational performance, waste stream and efficiency analysis and capacity management for the users, and allows efficient control and maintenance of number of facilities with minimal input from day-to-day users of the processing units.    DETAILED DESCRIPTION - The waste processing system comprises a pulper (310) for removing non-biodegradable material from the waste and pulping the biodegradable material, an anaerobic membrane bioreactor comprising microorganisms for producing biogas and anaerobic effluent from the pulped biodegradable material (316), and a membrane for retaining the microorganisms and a solid portion of the biodegradable material in the anaerobic membrane bioreactor. The removal of non-biodegradable material in the pulper protects the membrane of the anaerobic membrane bioreactor. A hydrocyclone is used to couple the pulper to the anaerobic membrane bioreactor for removing grit from a suspension of the pulped biodegradable material prior to its introduction into the anaerobic membrane bioreactor. The anaerobic effluent comprises a sludge and a permeate comprising nutrients and minerals. The water extracted from the permeate is used as process water in the pulper. A heater is used for heating an interior of the pulper so as to solubilize the biodegradable material. Waste containers are used for transporting the waste to the pulper, and comprise microorganisms for partially degrading the waste during transport. INDEPENDENT CLAIMS are included for:    (1) a method of managing a waste stream comprising biodegradable material; and    (2) a method for processing waste.
