Coal Ash Beneficiation Projects North Carolina

Coal ash beneficiation reuses coal ash from surface impoundments to produce cementitious products, like concrete. The Coal Ash Management Act (CAMA), as amended, required Duke Energy to identify three impoundment sites suitable for beneficiation projects. The law required each of the three projects to be capable of annually processing 300,000
