Abstract

Detection of Dioxins in fly ash of the two MSW Incinerators in Kyoto City was introduced with Analytical Chemistry in 1979. For the correspondence of this report, the approach to the Control of Dioxins in the Kyoto Municipal Government was begun. In the 1980's, Investigation of the Analytical Method and Control Technology of Dioxins advanced in Kyoto City through the collaboration of Kyoto University and plant makers. Since the guidelines for preventing dioxins from MSW Incinerators were indicated by the Ministry of Health and Welfare in 1990, the Kyoto Municipal Government analyzed Dioxins by form, and the results were announced. The control of Dioxins on already constructed MSW Incinerators was executed by reinforcement of operation and remodeling of the incinerator. For the construction project of a new MSW Incinerator in 1996, the Best Available Technologies of incineration and gas treatment were introduced and the design criteria with the exhaust gas concentration of Dioxins being less than 0.1ng-TEQ/N? was established. This report describes the details of examples of the control of Dioxins from MSW Incinerators and future directions for the treatment of waste.

Key words: Dioxins, the control of dioxins, already constructed MSW Incinerator, new MSW Incinerator, the Kyoto Municipal Government
