The emission of halogens and sulfur dioxide and the formation of water-soluble compounds of heavy metals are suppressed in the pyrolysis of waste in a carbonization zone at a temperature in the range from 300.degree. to 600.degree. C. by adding a fine-grained basic material to the waste prior to completion of the pyrolysis of the waste in the carbonization zone.
