STAR Technology
Reclaiming and Recycling Coal Ash
Our proprietary beneficiation technology, STAR Technology, transforms coal ash from ponds, landfills, and production material into a consistent, high-quality product for the concrete industry and other industrial applications.
In continuous operation since 2008, STAR Technology is a self-sustaining exothermic process with no residual ash waste stream. Excavation and beneficiation with STAR Technology offers a permanent solution, as coal ash is eliminated.
The process provides a consistent, low LOI material that meets or exceeds all specifications for additives in concrete. STAR Technology is a commercially proven, sustainable solution to permanently remove coal ash from the environment.
