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 slag, flue gas desulfurization gypsum (FGD or "synthetic" gypsum), and other flue gas materials captured by emissions controls.
