Presently, emissions of dioxins are mainly from incinerators, domestic and industrial coal combustion, and traffic. However, the major public concern and research effort are associated with the emissions of organic micropollutants from waste incinerators. Therefore, this paper attempts to give a brief overview on the more recent research and development for the removal of dioxins and heavy metals from flue gas streams. Special attention is devoted to the origin and control of emissions from incinerators. From the study presented it is possible to conclude that flue gas cleaning systems in modern incinerators are very reliable in removing almost all polluting emissions from flue gas streams, however the fly ash residues generated pose a significant disposal problem. In this way, the fly ash has to be managed carefully as it is enriched with heavy metals and organic micropollutants.
