TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Process: The commercial process includes at least on-site cleaning use of liquid carbon dioxide or supercritical carbon dioxide. The commercial process also includes using liquid carbon dioxide or supercritical carbon dioxide in a polymeric material cleaning process that is part of a polymer recycling process, where venting of gases, separating of gases into at least three streams, burning of a portion of the hydrocarbon stream, and use of energy from burning to power a process that takes place within 18 km radius from the separation of gases into at least three gas streams. Plastic is reduced in size to smaller segments of polymer during the polymer recycling process, and the smaller segments are cleaned with carbon dioxide from the carbon dioxide stream. A solvent is used to remove material from the smaller segments of polymer in addition to the use of carbon dioxide used to clean the smaller segments of polymer. The cleaning process comprises an apparel cleaning process. The cleaning process comprises a dry cleaning process where clothes from collection sites are transported to a cleaning area within a radius of 18 km of the gas separation site, and energy from burning of at least a portion of the hydrocarbon gas stream is used to power equipment used in the apparel cleaning process. At least some hydrocarbon gas is used in a carbon black production process. At least some carbon dioxide from the carbon dioxide stream is transported through a pipe system and used from the pipe system in a polymeric cleaning process, and cleaned polymer from the polymer cleaning process is palletized. At least some carbon dioxide from the carbon dioxide stream is transported through a pipe system to an apparel cleaning facility and used in an apparel cleaning process. A carbon dioxide stream after cleaning of apparel is purified and recycled into the apparel cleaning process. At least some carbon dioxide from the carbon dioxide stream is used in a polymeric cleaning process, and cleaned polymer from the polymer cleaning process is palletized and label removed from palletized polymer using a cosolvent system comprising a first cosolvent from terpenes, D-limonene or paraffinic hydrocarbons, and at least one second cosolvent from 1-6C alkyl lactates. Preferred Component: The waste gas stream site comprises a site having distinct cells of landfill waste mass and controls are present so that waste gas stream sites may be opened and closed from selected cells to control waste gas flow through the system.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The solid material waste site comprises a landfill. The solvent is an organic solvent to assist in the dissolving of adhesive or glue on the smaller segments of polymer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The carbon dioxide used to clean the smaller segments comprises supercritical liquid carbon dioxide.
