Abstract

In order to cope with changes of circumstances related to waste, the Waste Disposal and Public Cleansing Law was entirely amended in October 1991; it was put in force in July 1992. The Amended Law has a new system which is called "Specially Controlled Waste" ; that is to say, it is a system to deal with waste with hazardous characteristics (harmfulness to human health, living environment, and so on), which must be supervised more strictly than other waste. Soot and dust, caught by the dust collection equipment at domestic waste incineration plants is one of the Specially Controlled Wastes. In this report, we mention the new designations background, treatment in the Amended Law, dust characteristics, dust discharge under actual conditions, and trends over the next few years, concerning Soot and Dust as Specially Controlled Domestic Waste.

Key words: specially controlled waste, soot and dust, dust collection equipment, domestic waste incineration, separate discharge
