Dioxin mass balance in a municipal waste incinerator

A dioxin mass balance in an Spanish municipal waste incinerator (MWI) is pr esented. Input and output inventories from two sampling Collection episodes including the analysis of PCDD/PCDF in urban solid waste (USW), stack gas emissions, fly ash and slag are reported. In one collection the levels of U SW were around 8 pg I-TEQ/g and non-thermal destruction was observed overal l. In the other collection the levels of USW were higher (around 64 pg I-TE Q/g) and the dioxin balance revealed a thermal destruction. Analysis of the different waste materials (textile, organic, plastic, wood and paper) was performed separately and the textile samples presented the highest levels. (C) 2000 Elsevier Science Ltd.
