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.
A long-time leader in the fly ash utilization industry, SEFA developed the Staged Turbulent Air Reactor (STAR®) Process, which treats fly ash in such a way as to lower the LOI for use as pozzolan in concrete. The STAR® Process can also remove all the carbon in fly ash so that the purified mineral material can be used as raw feed material in other products and processes that historically have been unable to use fly ash as raw feed material because of the deleterious effect of residual carbon in fly ash.
With STAR® Technology, coal ash is transformed for beneficial reuse. The ash is processed from an industrial waste into a high-quality, mineral-based product that adds value in concrete and has a wide range of industrial uses.
