Processing of Plastic Waste and Scrap Tires into Chemical Raw Materials, Especially by Pyrolysis

Abstract

Abstract An account of the occurrence of pyrolyzable material and the state of development of pyrolysis processes in the USA and Japan is followed by a description of laboratory and pilot‐scale experiments designed to exploit the raw material content of pyrolyzable substances rather than the heating value. Plastic waste and scrap tires can be pyrolyzed to give up to 40% by weight of aromatic compounds in fluidized sand beds which are surprisingly insensitive to the unit size of the feed material.
