Company Overview


At SEFA, we leverage technology in every aspect of our business to provide exceptional solutions to partners and customers, now and in the future. Like many of our innovations, new technologies were developed to solve complex issues in our industry. With increasing demand for high-quality fly ash, SEFA recently developed a new forecast model to evaluate the estimated future demand for material, and make ash marketing more predictable and efficient.


The foundation of our Company is the willingness to serve. For over 40 years, SEFA has focused on providing a reliable supply of quality fly ash for the ready mix concrete industry. Throughout our history, we have also customized and added services that our utility or construction customers needed at the time. SEFA continues its strong heritage of integrity, excellence, safety, and unsurpassed service to its customers.


SEFA is a technical service and solution provider principally engaged in processing and marketing environmentally sustainable products derived from fly ash for the concrete industry. SEFA has recycled over 20 million tons of fly ash in the last 30 years, and the company is an integral part of some of the country’s most successful coal ash recycling programs. Our biggest impact is cleaning up coal ash from ponds and removing it from the environment permanently.

Leadership In Fly Ash Beneficiation

For four decades, The SEFA Group has been adept at stimulating innovation and new service offerings that can further contribute to customers’ success and environmental stewardship. Innovation begins with being a problem solver. Through SEFA’s determination, STAR® (Staged Turbulent Air Reactor) Technology was developed to provide the Company’s ready-mixed concrete customers an uninterrupted supply of recycled fly ash by utilizing and eliminating ash currently stored in impoundments. It is currently the only technology in the world transforming ash previously stored in ponds into a consistent, high-quality product for concrete. The heartbeat of SEFA is innovation, and the Company will continue to develop technologies, engineer processes, and invest in equipment that make a positive environmental difference for the future.
