Since 1976, SEFA’s core purpose has been to offer services and products to utilities, concrete producers, and related industries principally through maximizing the beneficial use of fly ash in environmentally sustainable ways. Through the years, SEFA has remained at the forefront of the coal ash marketing field, adapting and modifying the methods in an effort to meet the demand for specification-grade material.
SEFA developed its patented thermal beneficiation process, STAR® Technology, to lower the LOI of fly ash for use as a Pozzolan, or supplementary cementitious material, in concrete. The revolutionary STAR Process provided advantages over previous thermal beneficiation technologies, allowing SEFA to provide a high-quality fly ash.
The first STAR Plant, built and owned by SEFA, is the McMeekin STAR Plant in Columbia, South Carolina. It began operating in 2008.
The Morgantown STAR Plant, owned today by GenOn Holdings, LLC, began operations in 2012. It can recycle up to 350,000 tons of fly ash annually. SEFA operates and maintains the facility in Newburg, Maryland, and is the exclusive marketer of STAR Fly Ash from Morgantown to ready mixed concrete producers.
The third STAR facility, the Winyah STAR Plant, represented a giant step forward for SEFA, the industry, and the environment, by combining the STAR Process with the technical flexibility to recycle coal ash stored in ash ponds. SEFA began commercial operations at the new facility in 2015. Since commercialization, it has reclaimed and processed nearly 1.5 million tons of coal ash from onsite impoundments, producing over 1 million tons of STAR product ash.
