CA 2143841
A method for the processing of solid organic sulphur-containing waste, in particular ion exchange media, from nuclear fa- cilities, which method comprises that in a first step a) the waste is subjected to pyrolysis at the most at 700 °C, in a step b) the gas resulting from step a) is subjected to pyrolysis, in an optional step c) the gas resulting from step b) is exposed to a reluctant bed, and in a step d) the gas from step b) or alternatively step c) is exposed to a bed of sulphide-forming metal to form metal sulphides and easily manageable harmless gases. Apparatus for carrying out the method comprises A) a pyrolysis reactor for the solid waste, B) a pyrolysis reactor for the gas from A), C) optionally, a reluctant bed, and D) a bed of a sulphur-forming metal for the gas from B) or C).
