NOVELTY - The system comprises: a hopper (350) to receive a raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction; a waste heat exchanger coupled to the hopper to recover waste heat from an external heat source and transfer the recovered heat to the hopper to heat the raw biomass waste; and a pressurized and heated reactor (311) coupled to the hopper to receive the heated raw biomass waste. The reactor comprises a conveyer to compact the heated raw biomass waste, and a combustor (320).    USE - The system is useful for dissociation of raw biomass waste into a renewable fuel and/or a carbon byproduct, where the renewable fuel comprises hydrocarbon comprising methane and ethane, alcohol comprising methanol and ethanol, ammonia and hydrogen, the raw biomass waste comprises organic material containing carbon, hydrogen and oxygen obtained in response to photosynthesis and glucose, lignin and cellulosic feedstock and the carbon byproduct comprises carbon dioxide, carbon monoxide and carbon (all claimed), and for producing electricity, valuable chemicals, soil nutrients and materials from organic feedstocks particularly including energy crops and wastes.    ADVANTAGE - The system is capable of rapidly and economically converting the biomass wastes into renewable fuel and carbon products with high energy conversion efficiency and throughput in an environmentally friendly manner.    DETAILED DESCRIPTION - The system comprises: a hopper (350) to receive a raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction; a waste heat exchanger coupled to the hopper to recover waste heat from an external heat source and transfer the recovered heat to the hopper to heat the raw biomass waste; and a pressurized and heated reactor (311) coupled to the hopper to receive the heated raw biomass waste. The reactor comprises a conveyer to compact the heated raw biomass waste, a combustor (320) to generate heat used in the anaerobic reaction to dissociate the compacted biomass waste to produce the renewable fuel and/or carbon byproduct, and a countercurrent heat exchanger to transfer heat from the produced renewable fuel and/or carbon byproduct to the compacted biomass waste that travels in a counter-flow direction from the advancing compacted biomass waste. The external heat source comprises a device for generating renewable energy comprising a wind energy generator, a solar energy generator, an energy generator from running water and a geothermal energy generator. The conveyer is configured to: advance the compacted biomass waste towards a dissociation zone for dissociating the compacted biomass waste; and remove moisture and air from the advancing compacted biomass waste. The conveyer comprises a progressively reduced pitch of helical flights of rotating tubes on an exterior surface of the conveyer to facilitate the removal of moisture and air. The pressurized and heated reactor is shaped to reduce a cross sectional area within the reactor for advancing the compacted biomass waste material while facilitating the removal of moisture and air. The system further comprises: a hydrocarbon conversion system comprising heat exchangers coupled to the reactor to receive the hydrocarbon and further coupled to the heat source to receive heat used to separate the hydrocarbon into hydrogen and carbon; and a catalytic reaction zone for receiving a catalyst to facilitate formation of the renewable fuel comprising a hydrocarbon. An INDEPENDENT CLAIM is included for a method for processing biomass wastes to produce a renewable fuel and/or a carbon byproduct.
