NOVELTY - Use of gases collected from a solid/liquid material waste site, comprises separating collected gases from material waste site into hydrocarbon stream, carbon dioxide stream, and/or residue stream; condensing portion of carbon dioxide stream or hydrocarbon stream to liquid or supercritical liquid; using portion of hydrocarbon stream to generate energy; and using energy from hydrocarbon stream to power commercial process hydrogen production.    USE - The invention is for use of gases (e.g. hydrocarbon gas) collected from a solid/liquid material waste site to generate energy at the site (e.g., by burning to create heat/thermal energy, to drive a motor or engine, or to generate electricity), provide a hydrogen fuel source, and provide carbon black. The energy from the hydrocarbon stream is used to power a commercial process, e.g. carbon dioxide liquefaction, hydrogen production, carbon black production, cleaning with carbon dioxide as a cleaning material, molding polymeric materials, cleaning paper, cleaning cardboard, recycling paper, recycling cardboard or pelletizing polymeric materials.    ADVANTAGE - The invention makes landfills better able to service the environment and assists in the recycling of materials not added to the landfill mass. It maximizes removal of gas from each cell and each landfill site.    DETAILED DESCRIPTION - Use of gases collected from a solid/liquid material waste site, comprises:    (1) collecting gases from the material waste site;    (2) separating the collected gases into at least three streams comprising a hydrocarbon stream, a carbon dioxide stream, and residue stream;    (3) condensing at least a portion of the carbon dioxide stream or hydrocarbon stream to a liquid or supercritical liquid;    (4) using at least a portion of the hydrocarbon stream to generate energy; and    (5) using energy from the hydrocarbon stream to power a commercial process from carbon dioxide liquefaction, hydrogen production, carbon black production, cleaning with carbon dioxide as a cleaning material, molding polymeric materials, cleaning paper, cleaning cardboard, recycling paper, recycling cardboard or pelletizing polymeric materials.    An INDEPENDENT CLAIM is also included for a system of combined processes operating from a source of at least three gas streams from a waste gas stream site including:    (1) energy production, carbon black production, and hydrogen production;    (2) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, and apparel cleaning;    (3) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, and plastic cleaning;    (4) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, plastic cleaning and pelletization of cleaned plastic;    (5) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, plastic cleaning, plastic pelletization, and plastic molding or extrusion;    (6) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, and aluminum cleaning;    (7) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, aluminum cleaning, and cleaned aluminum ingot/sheeting formation;    (8) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, and glass/ ceramic cleaning;    (9) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation, glass cleaning and glass melting processes; or    (10) energy production, carbon dioxide liquefaction, supercritical or liquid carbon dioxide formation and solvent distillation processes, where energy production comprises providing at least some energy derived from combustion of hydrocarbon gases from at least one of the three gas streams.
