Chromated Copper Arsenate (CCA) is a popular wood preservative applied to wood products to prevent environmental decay during outdoor use and hence has been predominant in the disposal sector in recent years. Estimates suggest that some CCA treated wood waste in Florida is burned to produce energy. Incineration results in volatilization of metals during combustion and an accumulation and subsequent leaching of metals in the ash. This poses health and environmental concerns. Past studies have shown that many mineral sorbents are effective in controlling heavy metal volatilization in air phase during incineration. The objective of this study was to evaluate the viability of thermal processes in existing facilities as an option for the management of CCA wood waste in the state of Florida.
