The US has over 800 million tons of coal ash stockpiled and available for aboveground mining. Increased use of coal will add 100 million tons a year. Fly ash, which represents about 75% of the total, is the most versatile in its range of applications. These include the manufacture of cement, brick, roofing felt, mineral-wool insulation, highway subgrading, etc. Bottom ash, or boiler slag, is useful for sand blasting, water treatment filtration, road deicing, cold mix asphalt, and structural fill. Demonstrations using ash for these and other uses have been impressive. Using coal ash will not only eliminate stockpiling problems, but will preserve other natural resources and create high-value and high-quality products.
