Beneficiation
Coal Ash Beneficiation
Beneficiation is a process to improve the physical properties of coal combustion products for recycled use. Our team has over 25 years’ experience in designing and operating beneficiation facilities to maximize the beneficial use of fly ash in environmentally sustainable ways. Through the years, we were at the forefront of beneficiation and coal ash recycling. STAR® Technology, our proprietary thermal beneficiation process, was developed in 2006, and we were the first company using thermal beneficiation to process harvested ash from legacy coal ash ponds in 2015.
The concrete industry needs a consistent supply and consistent quality of fly ash, which is readily available through harvesting. Thermal beneficiation transforms coal ash from impoundments into a consistent, high-quality ash for recycled use that meets or exceeds industry specifications.
With our sustainability commitments, we also look at the full lifecycle of the project at beneficiation facilities. We are proud of our technologies to maximize the use of material with co-mingling and minimize waste streams.

Technologies & Solutions
Our technologies, strategies, and techniques to beneficiate coal ash are continually advancing to increase recycling and reduce our environmental footprint. With over 25 years' experience in operating beneficiation facilities, we are uniquely qualified to offer a wide range of solutions to remove and recycle coal ash for beneficial use.
Each coal ash impoundment and each utility are unique, which is why we do not have a “one size fits all” system. We work with our utility partners to optimize a beneficiation solution to meet their needs. Where harvested ash does not require thermal beneficiation processing to produce specification-grade material for concrete applications, we offer customized solutions to recycle coal ash.
