Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and flue-gas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other applications.
