Abstract
The present invention relates to a method for treating waste material comprising organic components and low and/or medium level radioactive agents. The method comprises encapsulating the waste material into a matrix, gasifying the waste material at a temperature between 600 and 950° C. to form a gaseous fraction and a solid fraction comprising low and/or medium level radioactive agents and combustion residues of the organic components and encapsulating the solid fraction by a geopolymer matrix comprising metakaolin.
