Research Abstract	Since the waste wood treated by preservatives containing heavy metals contains heavy metals, it may cause the environmental pollution or destruction of ecological systems if waste wood is treated without appropriate measures. In the present study, the utilization of waste wood treated by CCA preservative as an energy source by thermal recycling is considered and thus development of safe gasification process is the target of this study. While most of copper and chromium remains in the residue, arsenic vaporized to gas phase by gasification considerably and the fraction of vaporized arsenic increased with temperature. It is important to gasify waste wood at lower temperature or to add proper materials to stabilize arsenic in the gasification residue.
