Coal Combustion Wastes

Coal Combustion Wastes

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 fluegas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other appliions.

Coal is an important part of the world energy budget. It is relatively inexpensive to loe and extract, and can be found all over the world. Unlike many renewable resources (such as solar or wind), coal production is not dependent on the weather. It is a baseload fuel, meaning it can be produced 24 hours a day, 7 days a week, 365 days a year.
