The electron beam technology for decomposition/elimination of dioxin contained in flue gas has been developed using real waste gas of 1,000 mN/h released from the municipal solid waste incineration facility at 200C. The decomposition efficiency, the ratio of toxic equivalent dioxin concentration before and after EB irradiation to doses above 15kGy is higher than 90%, which clears the regulation limit in the Japanese special measures of dioxin release. The chemical process of dioxin decomposition was studied and low-toxicity of irradiated gas was confirmed in terms of endocrine disrupter influence.
