The disposal of post-consumer plastics has become an increasingly serious environmental problem throughout the world as well as in the United States. Recycling the mixed plastics wastes to liquid or gases provides a means for reutilizing the hydrocarbons as fuels or chemical feedstock and abstracting the energy or chemical value from the waste material. Pyrolysis and liquefaction of waste plastics as well as liquefaction of waste plastics with coal have been explored by a number of researchers. The supply of waste plastics is limited; even if all of the waste plastics were recycled to transportation fuels, only one month`s supply of would be available on annual basis. The feasibility of tertiary waste plastics recycling is limited by the availability of waste plastics and the constancy of the supply. Hence, waste plastics liquefaction can provide a valuable addition to our energy supply but will not substantially affect self-sufficiency. Utilization of a native natural resource such as coal in conjunction with waste plastics will not only provide sufficient hydrocarbon resources and a constant feedstock supply but will also provide more self-sufficiency in our energy supply. This report presents results of two-stage coprocessing of a bituminous coal with waste plastics. The plastics were first liquefied, then the coal was liquefied with the hexane soluble from the first stage.
