Coal combustion products (CCPs), also called coal combustion wastes (CCWs) or coal combustion residuals (CCRs), [1] are categorized in four groups, each based on physical and chemical forms derived from coal combustion methods and emission controls:

This Fact Sheet answers questions about present and potential uses of coal combustion products. What are coal combustion products? Coal combustion products (CCP's) are the inorganic residues that remain after pulverized coal is burned.

What are coal combustion products? Coal combustion products (CCP) are the materials that remain after pulverized coal is burned to generate electricity. Coarse particles (bottom ash and boiler slag) settle to the bottom of the combustion chamber.

Coal combustion products – often referred to as “coal ash”– are solid materials produced when coal is burned to generate electricity. There are many good reasons to view coal ash as a resource, rather than a waste. Using it conserves natural resources and saves energy. In many cases, products made with coal ash perform better than

Coal combustion products (CCP's) are the solid residues generated by coal-burning electric utilities in the production of electricity. In 1998, electricity accounted for about 35% of the primary energy use in the United States and was produced by electric power generators designed to convert different fuel types into electricity.

Coal combustion products (CCP) are the materials produced when we burn coal to generate electricity. They include fly ash , bottom ash , boiler slag , flue gas desulfurization gypsum , and other power plant byproducts.

2 Coal combustion products (CCPs) include fly ash, bottom ash, boiler slag, fluidised-bed com-bustion (FBC) ash, or flue gas desulfurisation (FGD) material produced primarily from the combustion of coal or the cleaning of the stack gases. The term coal ash is used interchange-able for the different ash types. Fig. 1.
