Who We Are

The American Coal Ash Association, established in 1968, is a nonprofit trade association devoted to recycling the materials created when we burn coal to generate electricity. Our members comprise the world’s foremost experts on coal ash (fly ash and bottom ash), and boiler slagflue gas desulfurization gypsum (FGD or “synthetic” gypsum), and other flue gas materials captured by emissions controls.

Mission Statement

The Mission of the American Coal Ash Association is to advance the management and use of coal combustion products in ways that are environmentally responsible, technically sound, commercially competitive, and supportive of a sustainable global community.

ACAA Member Benefits

Membership in ACAA provides support for the development, implementation, and continuation of effective programs for the management and use of CCPs. There are numerous benefits for coal-burning electric utilities resulting from the use of CCPs in lieu of disposal. In addition to avoiding disposal costs and creating revenue, added benefits come from public and government recognition of the utility as a supporter of sound policies for recycling and sustainable development. ACAA members share a common interest in using CCPs as valuable products to enhance revenues, minimize disposal costs, reduce liability, and support environmental policies. ACAA members are active at national, regional, state, and local levels.

Beneficial Use of Coal Combustion Products

Sixty-two percent of the coal ash produced in 2022 was recycled – the eighth consecutive year that more than half of the coal ash produced in the United States was beneficially used rather than disposed.
