NOVELTY - A waste processing system (100) comprises: input configured to receive a heterogeneous waste stream including biodegradable and non-biodegradable components; pulper fluidly connected to the input, the pulper configured to mechanically de-fiber the biodegradable components of the heterogeneous waste stream to form a de-fibered biodegradable material; and an anaerobic membrane bioreactor fluidly connected downstream of the pulper.    USE - As a waste processing system, used in waste recovery, conversion, and distribution system (claimed), for recovering biodegradable waste for conversion into useful products such as food products selected from fresh produce such as fruit and vegetables, grains, dairy products, meats, shelf-stable or containerized foods (e.g. cartonned, canned, or bagged goods), and animal feed.    ADVANTAGE - The system generates energy by waste generator (e.g. supermarkets and restaurants) and provides a source of fertilizer for local farmers, recovers economic and environmental value from discarded waste, efficiently and economically.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) processing a waste stream involving receiving a heterogeneous waste stream including biodegradable waste and non-biodegradable waste at a waste processing facility; separating the biodegradable waste from the non-biodegradable waste; mechanically de-fibering the biodegradable waste at a predetermined temperature in a pulper to form a de-fibered biodegradable waste; and anaerobically digesting the de-fibered biodegradable waste in an anaerobic membrane bioreactor to produce biogas, permeate, and anaerobic effluent; and    (2) waste recovery, conversion, and distribution system comprising: food distribution facility (120); food retailing facility; waste processing facility (110) containing input configured to receive a heterogeneous waste stream including biodegradable components and non-biodegradable components; separator configured to separate the biodegradable components from the non-biodegradable components; pulper fluidly connected to the input, the pulper configured to mechanically de-fiber the biodegradable components of the heterogeneous waste stream to form a de-fibered biodegradable material; and anaerobic membrane bioreactor fluidly connected downstream of the pulper, the anaerobic membrane bioreactor configured to produce biogas and anaerobic effluent from the de-fibered biodegradable material; and shared transportation infrastructure configured to deliver food from the food distribution facility to the food retailing facility and to deliver the heterogeneous waste stream from the food retailing facility to the waste processing facility.    DESCRIPTION OF DRAWING(S) - The figure shows a block flow diagram of system for distributing food products and collecting and processing heterogeneous waste.
