It involves the thermal treatment of waste materials in a sealed vessel under high temperature and pressure, with limited availability of oxygen to produce highly ionized and electrically charged syngas for the generation of electricity and heat.

Abstract
The process of collection, transport, disposal, recycling, and monitoring of wastes is called waste management. The waste management is undertaken to recycle the wastes so as to reduce the ill effects of wastes on environment, health, and aesthetics. There are several kinds of wastes produced such as agricultural wastes, municipal wastes, industrial waste, mining waste. Some wastes are more hazardous such as medical wastes and nuclear wastes. Various techniques are used for the management of wastes which includes landfilling, incineration, anaerobic digestion, pyrolysis, plasma gasification, recycling, composting. Anaerobic digestion produces biofuel in the form of biogas. Plasma gasification results in the generation of electricity from wastes. Recycling of wastes involves the collection, sorting, and reprocessing of wastes into new products. Vermicomposting is the preferred form of composting as it results in the formation of vermicompost called black gold due to the presence of rich nutrients and growth promoting factors in it.
