Incineration - Wikipedia

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment".Incineration of waste materials converts the waste into ash, flue gas and heat.
