Municipal solid or other waste is treated in apparatus comprising an autoclave treatment plant for steam treating the solid waste and a supercritical oxidation reactor downstream of the autoclave treatment apparatus for converting a product stream to heat, water and carbon dioxide. The product stream may be an organic-rich stream form the autoclaved material or may be sludge from an anaerobic digestate of the organic- rich stream. In either case, disposal of sludge in landfill or by incineration is avoided. |
