Coal Ash. Burning coal produces airborne compounds, known as fly ash and bottom ash (collectively referred to as coal ash), which can contain large quantities of heavy metals that settle or wash out of the atmosphere into oceans, streams, and land. The amount of fly ash is going up: in 2006, coal plants in the United States produced almost 72 million tons, up 50 percent since .
Coal ash is the solid waste generated during coal combustion and includes fly ash, bottom ash, and sludge from flue gas desulfurization units. In the United States, t he combustion of coal generates more than 100 million tons of coal ash each year. Half of these wastes is reused for beneficial purposes such as the manufacture of concrete and other construction materials. Coal ash is also ...
