STAR® (Staged Turbulent Air Reactor) Technology is our patented thermal beneficiation process to transform coal ash from surface impoundments or ponds into a high-quality, sustainable product for the concrete industry. The reliable, consistent quality of STAR beneficiated ash allows it to be used at a higher volume, and in more building projects, than fly ash from other sources. STAR® ash is also recognized as an innovative process aid for the rubber, plastics and silicone industries.
