Plasma gasification is a gasification process that decomposes biomass into basic components, such as H2, CO, and CO2 in an oxygen-starved environment at an extremely high temperature. Plasma is regarded as the 4th state of matter; it is an ionized gas produced by electric discharges. A plasma torch is a tubular device that has two electrodes to produce an arc. It is an independent heat source that is neither affected by the feed characteristics nor the air/oxygen/steam supply. When electricity is fed, an arc is created, and the electricity is converted into heat through the resistance of the plasma. A plasma torch can heat the biomass feedstock to a temperature of 3000 “C or higher (up to 15,000 °C). Under such extremely elevated temperature, the injected biomass stream can be gasified within a few milliseconds without any intermediate reactions. The plasma technique has high destruction and reduc­tion efficiencies. Any form of wastes, for example, liquid or solid, fine particles or bulk items, dry or wet, can be processed efficiently. In addition, it is a clean technique with little environmental impact. Plasma technique has great application potential for treating a wide range of hazardous wastes (Zhang et al., 2010).
