Fifty-two percent of the coal ash produced during 2019 was recycled, marking the fifth consecutive year that more than half of the power generating station byproduct in the United States was beneficially used rather than disposed. The volume of fly ash used in concrete, 12.6 million tons, marks a 1 percent increase over 2018 consumption. Year-over-year use of fly ash…

Supply dynamics in key regional markets, primarily linked to coal-fueled power plant closures, spurred an 11 percent year-over-year decline in fly ash consumption in concrete, according to the American Coal Ash Association’s (ACAA) just-released “Production and Use Survey” for 2018. Concrete-grade ash accounted for 12.5 million of the 59.4 million tons of coal combustion products (CCP) beneficially used last year; use of all CCP grades in cement production dropped to 6.4 million tons, off 26 percent from 2017 levels.

“We are pleased to report that 52 percent of coal combustion products were beneficially used in 2015—up from the previous year’s record of 48 percent. For the first time, we are using more of these valuable resources than we are throwing away,” reports American Coal Ash Association Executive Director Tom Adams, taking stock of the central metric in the group’s latest “Production and Use Survey.”

The volume of coal fly ash used in concrete production increased to 13.1 million tons in 2014, exceeding the 12.6 million ton utilization mark set in 2008, according to the American Coal Ash Association’s (ACAA) “Production and Use Survey,” released in late 2015. Increases in the use of synthetic gypsum from power plant emissions control equipment also helped to push the recycling rate for all types of coal combustion products (CCP) to a record 48 percent.

Backed by findings from an American Coal Ash Association (ACAA) report on U.S. production and utilization of coal combustion products (CCP), the top marketer of ASTM C 618-grade fly ash foresees 20 years of supply chain stability—countering the perceived effect of present regulatory and energy market forces reshaping power utilities’ fuel profile.

The American Coal Ash Association Educational Foundation awarded $7,500 in scholarships to two university students with interests in advancing the sustainable and environmentally responsible use of coal combustion products. The Foundation also announced new names for the scholarships honoring coal ash beneficial use industry leaders.
According to American Coal Ash Association’s (ACAA) “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.
