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.
coal - coal - Coal types: Coals contain both organic and inorganic phases. The latter consist either of minerals such as quartz and clays that may have been brought in by flowing water (or wind activity) or of minerals such as pyrite and marcasite that formed in place (authigenic). Some formed in living plant tissues, and others formed later during peat formation or coalification.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.
