Incineration is a waste treatment process that involves the combustion of 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.

In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper. Example) Value of Free Cu = Cu content x (Recovery% - Payable Cu %) x LME Cu price: 30% x (98.0% - 96.65%) x 7,000 USD/t-Cu = 28.4 USD/DMT Boliden Commercial AB 17
