EMISSIONS OF POLYCHLORINATED COMPOUNDS IN COMBUSTION OF BIOFUEL

The aim of this project is to study the formation of polychlorinated o rganic compounds when miscellaneous packaging material is burned in or der to evaluate the emission of specific toxic compounds such as chlor inated dioxins. The packaging materials have also been combusted toget her with waste pellets with a composition corresponding to municipal s olid waste (MSW) in order to determine the contribution of the packagi ng material to the total emission. Exclusively model waste pellets, us ed packaging pellets and a pelletized biofuel have been burned with th e intention of using these as references in this study. The results cl early show that the paperbased packaging material is comparable with b iofuel. The emission is comparable to the emissions from the combustio n of biofuel. No increase in the emission of chlorinated organic compo unds could be seen even when the paperbases hold extended amounts of a luminum or copper. The results of the biofuel and model waste combusti on experiments are in agreement with data from full scale incinerators , consequently the emissions from combustion of the paperbases in the pilot reactor are comparable to emissions in full scale combustors wit hout flue gas cleaning.
