Abstract

A method for the thermal utilization of combustible components of waste materials of different properties and origin, independently of the degree of contamination with heavy metals and toxic organic compounds or organic chlorine-containing compounds. The waste materials are subjected to the method steps of pyrolysis, comminution, classification, gasification and gas purification in order to produce a clean gas which can be used for various purposes and as a source of energy and an elution-proof, mineral, solid residue which can be easily disposed of.
