45. Incineration  is a  waste treatment process  that involves the  combustion  of  organic  substances contained in waste materials. [1]  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. The ash is mostly formed by the  inorganic  constituents of the waste, and may take the form of solid lumps or  particulates  carried by the flue gas.

46. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the  atmosphere . In some cases, the heat generated by incineration can be used to generate  electric power . Incineration with energy recovery is one of several  waste-to-energy  ( WtE ) technologies such as  gasification ,  pyrolysis  and  anaerobic digestion .. [2]
