Plasma technology is showing promise for a variety of waste processing applications. The attractiveness of plasmas results from the capability to provide high temperatures, a high degree of controllability, and the use of electricity for heating rather than heat from combustion. Plasma refers to every gas of which at least a percentage of its atoms or molecules is partially or totally ionized. In a plasma state of matter, the free electrons occur at reasonably high concentrations and the charges of electrons are balanced by positive ions. As a result, plasma is quasi-neutral.
