NOVELTY - A system (10) comprises a first subsystem for receiving and filtering pumpable, non-biodegradable waste (100); a second subsystem for receiving and resizing non-pumpable, non-biodegradable waste; a third subsystem for receiving and resizing biodegradable waste; a molten metal bath gasifier (MMBG) having a molten metal bath for receiving non-biodegradable wastes; an anaerobic digester (140) upstream from the MMBG, for receiving the biodegradable waste outputted from the third subsystem and for producing a biogas and effluent; and an alternating current (A/C) plasma reactor (150).    USE - For efficiently converting heterogeneous waste materials consisting of biodegradable and/or non-biodegradable wastes into a high quality syngas for production of methanol and synthetic fuels (claimed). Syngas is commonly used as the feedstock in a number of catalysis processes to produce a wide range of industrial, commercial and consumer products. Methanol is used in production of formaldehyde and acetic acid, both precursors to numerous adhesives, glues, plastics and other materials, used as solvent, antifreeze, and windshield washer fluid, converted into hexane-the primary constituent of motor gasoline, and used as critical feedstock in the production of bio-diesel.    ADVANTAGE - The entire system is closed-loop, without producing combustion, greenhouse gas emissions, or landfill residuals. The system produces a net output of electricity above plant load sufficient for the co-production of renewable Hydrogen and oxygen, provides an efficient method for initial dissociation of materials due to its high operating temperatures compared to typical fixed bed, moving bed, fluidized bed or entrained flow gasifiers, and faster destruction and destruction rate efficiencies (DREs) compared to all lower temperature methods. Use of the melt as working media rather than as a heat sink significantly improves the process and energy efficiency of downstream gas clean-up processes by impounding a significant amount of the contaminates inherent in the feedstocks within the molten media, and preventing their release and incorporation into the process gas stream. The system conveys the dirty process gas into an A/C plasma reactor to complete the molecular dissociation process. Biogas from the anaerobic digester is used as a waste feedstock and/or a process gas for the A/C plasma reactor. All wastes created by the system are reprocessed as a feedstock back into the MMBG or A/C plasma reactor. Heat is recovered from all heat-generating elements and used to create steam and then electricity to reduce the operating cost of the system by generating its own electrical power. The entire system is managed by an integrated command/control management system to allow control of the type and amount of feedstocks entering the system, to allow control of the system components to adjust operation parameters to accommodate heterogeneity of waste material; and to allow for off-site monitoring of the system. The system processes waste more effectively and safely.    DETAILED DESCRIPTION - A system (10) comprises a first subsystem for receiving and filtering pumpable, non-biodegradable waste (100); a second subsystem for receiving and resizing non-pumpable, non-biodegradable waste; a third subsystem for receiving and resizing biodegradable waste; a molten metal bath gasifier (MMBG) having a molten metal bath for receiving the non-biodegradable wastes, the MMBG outputting a process gas from the non-biodegradable waste; an anaerobic digester (140) upstream from the MMBG, for receiving the biodegradable waste outputted from the third subsystem and for producing a biogas and effluent; and an alternating current (A/C) plasma reactor (150) disposed downstream from the MMBG and the anaerobic digester, and receiving process gas from the MMBG, and biogas from the anaerobic digester as a process gas and/or a working gas. The A/C plasma reactor converts the process gases from the MMBG and the anaerobic digester into a plasma phase and outputs raw syngas.
