Treatment of waste by DC arc discharge plasmas

The problem of the disposal of hazardous wastes has become very important in recent years. Plasma treatment is being developed and tested for incinerator ash, low level radioactive wastes, industrial and biomedical wastes, etc. by industrial companies and municipalities world wide. In this paper, the principles are discussed and examples of waste treatment such as fly ash, asbestos, aluminum, municipal wastes, low level nuclear wastes, etc. by using DC arc discharge plasma are shown.
