American Coal Ash Association

The American Coal Ash Association (ACAA) is a trade organization dedicated to promoting the sustainable use of coal combustion residuals (CCRs), commonly known as coal ash. It serves as a platform for data collection, research, and advocacy to improve understanding and management of coal ash by industry professionals, regulators, and researchers. The ACAA aims to encourage environmentally responsible practices, increase the beneficial reuse of ash in products like concrete and infrastructure, and support regulatory clarity to ensure safe and effective utilization of this byproduct from coal-fired power plants.
