The American Coal Ash Association recently released its annual Coal Combustion Product Production and Use Survey, reporting that 123.1 million tons of CCPs were produced in 2005. About 40% were used beneficially or 49.6 million tons. This represents a slight 0.21% increase from 2004 when 49 million tons of CCPs were used, of 122.4 million tons produced. An increase of 0.53% was reported for 2004. The use of coal combustion products, reported in 15 survey categories, creates a wide array of extraordinary environmental, economic and technical advantages that meet US industry and government objectives. Fly ash use accounts for 13 of 15 categories tracked by the survey. Of 71.1 million tons produced, 29 million was used in such applications as concrete products, structural fills and cement raw feed for clinker. Bottom ash production amounted to 17.6 million tons in 2005 - a slight 2.3% rise - while utilisation dropped 7% from 8 to 7.5 million tons. Of 11.8 million tons produced, 77.4% or 9.2 million tons of FGD gypsum was used in 2005. Boiler slag has the highest ratio of beneficial use at 96.6%. Of the 1.96 million tons produced, 1.89 million tons was used in 2005. 3 refs., 1 fig., 1 tab., 4 photos.
