PROBLEM TO BE SOLVED: To simultaneously sterilize and crush a pail, which stores a substance to be treated, without entraining air, in regeneration of energy by pyrolysis thermal decomposition as a method for treating an infectious medical waste.SOLUTION: When the pail is fed in a hermetically sealed feeding box, entrained air is deflated, and moreover, sterilization and crushing are carried out in a sterilization room, and, at the same time, the infectious medical waste is treated in electromagnetic induction superheated steam and pyrolysis high-temperature gas.【課題】 感染性医療廃棄物の処理方法として熱分解によるエネルギーの再生に於いて、前記処理物を収容したペール缶は空気を伴わずに殺菌破砕を同時に行うことは可能か。【解決手段】 密閉した供給箱にてペール缶供給時に同伴空気を抜気の上、殺菌室に於いて圧縮破砕と同時に電磁誘導過熱蒸気と熱分解高温ガスの中で処理する。【選択図】図1
