According to ACAA’s “Production and Use Survey,” 51.4 million tons of coal combustion products (CCP) were beneficially used in 2013 —down from 51.9 million tons in 2012 and well below the 2008 peak of 60.6 million tons. In the closely watched category of fly ash consumed in concrete mixes, utilization increased only slightly to 12.3 million tons, up by 577,705 tons over 2012, but still below 12.6 million tons in 2008.
