We studied an entrained-flow gasification process which efficiently converts waste plastics to energy at a high energy recovery rate. Waste plastics, after being shredded to <10mm, were fed into an entrained-flow gasifier with air, oxygen, steam and CO_2 gas. In the gasifier, organic substances were pyrolyzed, partially combusted, and then converted into synthetic gas (CO, H_2) at a high temperature (over 1,600K). Other inert substances in the wastes such as ashes and metals were melted into slag and condensed on bag filters. The bag filters and a water scrubber removed inpurities such as dust, heavy metals, and hydrogen halides from the product gases. Solid hydrocarbons, which include char and soot, were removed at a hot cyclone and on the bag filters
