Abstract

The conversion of waste plastics material to hydrocarbon fuel products, particularly transportation fuels. The waste plastics material can be obtained from any suitable source, such as a municipal solid waste facility and from agricultural and horticultural activity. The plastics material feed, which can contain from about 10 to about 50 wt. % dirt, is reduced to an effective size, then dried, if needed, to a moisture level of 2 wt. % and less, then screened to removed dirt, then densified into nuggets of at least about 10 lb/ft3, then pyrolyzed.
