Abstract
A plasma arc torch is used as an independent heat source in an enclosed reactor vessel to gasify municipal solid waste and produce a medium quality gas and an inert monolithic slag having substantially lower toxic element leachability. The gas has lower levels of metals and semi-volatile organic compounds, particularly dioxins and furans. Other materials may also be gasified, for example, coal, wood and peat.
