Description
Coal combustion products (CCPs) are frequently utilized as supplementary materials in cement and concrete manufacturing. With an estimated 2 billion metric tons stored in repositories across the United States, interest in beneficial use has expanded beyond class F fly ash to include ponded and high-LOI ash. Beneficiation provides a critical pathway for managing CCP repositories, particularly under closure-by-removal strategies, and where ash sources have historically been difficult to process. Research conducted at EPRI’s Ash Beneficial Use Center (ABUC) examines the feasibility of processing these ash types into usable products and offers insights into repository variability and classification. Furthermore, the study provides guidance on laboratory setup and organization to support similar investigations, reinforcing the role of beneficiation in advancing sustainable CCP management. By advancing practical solutions and improving material utilization, this research reduces environmental liabilities and supports more sustainable resource management across the utility industry.
