Successful deployments of treatment technologies for substandard coal combustion products (CCP) signal decades of Class F fly ash supplies for North American concrete producers. Such assurance stands regardless of specification-grade ash availability reflecting power generating station coal to natural gas conversions—or the pace of a broader energy sector shift from fossil fuels to alternative sources. With 6 percent to 15…

Coal ash product use in cement kiln feeds and concrete mixes approaches 18M tons
The American Coal Ash Association 2022 Production and Use Survey reflects 2021 data from coal-fired power stations, which yielded 77.3 million tons of ASTM C618 Class F or Class C ash and lesser grade coal combustion products (CCP), up from 69.1 million tons the prior year. When measured against prior year figures, 2021 saw: Fly ash consumption in concrete reach…

Read MoreFly ash use in concrete up slightly; overall ash recycling rate down
Source: American Coal Ash Association, Farmington Hills, Mich. 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…

Sixty-four percent of the coal ash produced during 2017 was recycled, establishing a new record rate and marking the third consecutive year that more than half of such material produced in the United States was beneficially used rather than disposed.
Read MoreCoal ash recycling at record rate despite lower concrete market consumption
Sources: American Coal Ash Association, Farmington Hills, Mich.; CP staff
The American Coal Ash Association’s just-released “Production and Use Survey” pegs 2016 Class F and Class C fly ash consumption in concrete at 14.4 million tons, down 8 percent from the prior year’s record 15.7 million tons. ACAA attributes the dip to regional supply shortages that resulted from power plant shutdowns and generating stations’ changing fuel profiles. Demand for fly ash remained strong across all concrete markets last year, the group affirms, and utilization likely would have been higher absent logistical disruptions.

Sources: Charah LLC, Louisville, Ky.
Charah will step up Class F fly ash supply capabilities to Illinois, Indiana and Kentucky concrete and cement producers through an exclusive agreement to market coal combustion products (CCP) from the Hoosier Energy Merom Generating Station in western Indiana. The contract is the latest a series supporting the company’s MultiSource terminal and processing site network.

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.
