SEFA Group Inc. will build a $40 million facility to recycle high-carbon fly ash in Georgetown, S.C.

The Lexington, S.C.-based SEFA, formerly the Southeastern Fly Ash Co., said in a news release the facility will use all of the fly ash produced at Santee Cooper's Winyah Generating Station, using a new recycling technology.

The facility also will recycle fly ash previously in ash ponds located at Winyah Station. Coal fly ash from other Santee Cooper electric generating stations also may be transported to the Winyah Station site for processing.

The new facility can recycle up to 400,000 tons of fly ash per year. SEFA will use the fly ash from the Winyah Station as a primary ingredient in its proprietary STAR (Staged Turbulent Air Reactor) process to produce a pure mineral product, free of organic contaminants.

The recycling plant’s primary product will be a supplementary cementitious material that is trademarked as STAR RP.
