Coal Combustion Byproducts (CCBs)

Coal Combustion Byproducts (CCBs) are the residuals created when coal is burned for energy. Coal consists of a large percentage of organic carbon, with a variable percentage of other naturally occurring minerals that may contain a wide range of elements including metals. A significant amount of volume reduction takes place when the coal is burned, as a large percentage of the organic carbon in the coal is con​verted into carbon dioxide. CCBs can contain potentially harmful amounts of some heavy metals, such as mercury, lead, chromium, cadmium, selenium, molybdenum, and boron, among others. Although not acutely toxic or immediately hazardous, the concentrations of these chemicals can be harmful to plant and aquatic life, and can render the air and both surface water and groundwater unhealthy for prolonged human consumption.
