Abstract

Dioxins are toxic and by many considered to be carcinogenic and mutagenic, hence control of dioxin emissions is now mandated by many governments. There are many technologies, which remove dioxins from flue gas streams, such as active carbon adsorption. However, these technologies only transfer the hazard associated with dioxins from the gas phase to the solid phase. This leaves the problem of disposing safely of dioxin containing waste, such that later release of dioxins from the adsorbent does not occur. To overcome these limitations a system has been developed which converts, rather than removes, dioxins to CO~2~, H~2~O, HCl and hydrocarbon fragments which are environmentally benign. This paper looks at the development of the technology from lab scale testing to commercial applications both in the Asia Pacific region and throughout the World.
