NOVELTY - Using gases collected from solid/liquid material waste site involves: collecting gases from the material waste site; separating the collected gases into at least three streams having hydrocarbon, carbon dioxide, and residue streams, followed condensing and generating energy from the hydrocarbon stream and using the energy from the hydrocarbon stream to power two commercial processes.    USE - For generating energy to power commercial processes such carbon dioxide liquefaction, hydrogen production, carbon black production, cleaning with carbon dioxide as a cleaning material, molding polymeric materials and palletizing polymeric materials (claimed).    ADVANTAGE - The process makes landfills better able to service the environment and to assist in the recycling of materials not added to the landfill mass, different technologies, processes and business models; provides a more economically viable system associated with landfills. The process uses the effluent gas streams, which are desirably found within the economic environment and local physical environment of the waste site and preferably physically within or adjacent to the waste site to improve the economic performance of the system. The process can uses multiple streams. The energy and products of the three gas stream can be used in a more unified efficiency and provide significant economic improvement to the entire system. The performance of at least the processes as grouped, and the addition of other processes from the other groups, particularly at a single site where transportation costs from process to process are reduced or eliminated can provide a gas stream site that can exceed mere survivability and produce a significant positive cash flow while improving waste utilization and increasing the benefits from recycling.    DETAILED DESCRIPTION - Using gases collected from solid/liquid material waste site involves:    (1) collecting gases from the material waste site;    (2) separating the collected gases into at least three streams comprising a hydrocarbon stream, 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 two commercial processes one process comprising carbon dioxide liquefaction and the other commercial process selected from hydrogen production, carbon black production, cleaning with carbon dioxide as a cleaning material, molding polymeric materials, and pelletizing polymeric materials.    An INDEPENDENT CLAIM is included for a system of combined processes operating from a source of at least three gas streams from a waste gas stream site are selected from:    (A) energy production, carbon black production, and hydrogen production;    (B) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, and apparel cleaning;    (C) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, and plastic cleaning;    (D) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, plastic cleaning and pellitization of cleaned plastic;    (E) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, plastic cleaning, plastic pellitization, and plastic molding or extrusion;    (F) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, and aluminum cleaning;    (G) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, aluminum cleaning, and cleaned aluminum ingot/sheeting formation;    (H) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, and glass/ceramic cleaning;    (I) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation, glass cleaning and glass melting processes; and    (J) energy production, carbon dioxide liquification, supercritical or liquid carbon dioxide formation and solvent distillation processes. The energy production comprises providing at least some energy derived from combustion of hydrocarbon gases from at least one of the three gas streams.
