ABSTRACT:
Method and installation or apparatus for the treatment of material contaminated with toxic organic compounds in which the material is subjected to a thermal treatment to destroy or decompose the toxic compounds, the thermal treatment being carried out in two stages, i.e. a first stage in which the contaminated material is heated to a temperature of not more than 500.degree. C. under pyrolysis conditions in an indirectly heated rotary furnace, and a second stage in which the solid residue remaining in the first stage is heated in a second furnace to a temperature of at least 500.degree. C. until the concentration of toxic organic compounds in the residue is in the ppb range and preferably 1 ppb or less, and in which the gaseous reaction products of the first and second stages are supplied to a combustion chamber and there burnt at a temperature which is sufficient to completely destroy all the toxic organic compounds contained therein.
