Coal combustion residues may be effective in neutralizing acid mine drainage and therefore reducing the overall transport of contaminants from acid-generating mine sites. However, CCRs often contain a mixture of metals and other constituents in sufficient quantities that they may pose public health and environmental concerns if improperly managed.

Management of coal combustion wastes

Management of coal combustion wastes 5 Burning coal in a coal-fired power plant produces a variety of solid residues known as coal combustion products (CCPs), coal combustion residues (CCRs) or coal combustion wastes (CCWs). CCPs are now more commonly called coal combustion by-products (CCBs) because of their increasing beneficial use.

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.
