PROBLEM TO BE SOLVED: To realize the safety treatment of waste in the simple waste gas treatment equipment by stabilizing a heating generation of the waste and keeping the complete combustion by a low air ratio in the fluidized bed incinerator. SOLUTION: The waste is crushed, charged into a thermal decomposition kiln 2, and indirectly and slowly heated under the absence of oxygen, whereby the waste is decomposed into a thermally decomposed gas 4 and a thermally decomposed solid matter 5 with uniformized heat generation. The generated thermally decomposed gas 4 and the thermally decomposed solid matter 5 are fed to a latter part of the fluidized bed incinerator for complete combustion with low air ratio. Noncombustible solid matter 8 is taken out of the incinerator bottom to be recovered in a state of being divided into iron 11, aluminum 13 and other noncombustible matters 12. As the waste having various calories by the kinds of wastes are fed to the fluidized bed incinerator after being thermally decomposed into the thermally decomposed solid matter and the thermally decomposed gas stable in calorie, the complete combustion with the low air ratio can be realized.
