In Japan, many existing MSW incineration plant have retrofitted for the purpose of reducing PCDD/DFs emission. Concrete contents of retrofit were generally following. Improving of combustion control, lowering temperature of the gas passing through the dust collectors, and enhancing the efficiency of the dust collectors (convert electrostatic precipitation to bag filter). These works are expected to be efficient for the reduction of other substance emission in the flue gas. Toxic substances emission (PBDD/DFs, MoBPCDDs/DFs Hg, Pb, Zn, Cr and other heavy metals) from two facilities which have been retrofitted were investigated. The result shows that some substances such as MoBPCDDs/DFs and Hg were decreased in the emission of the flue gas by the system improvement.
