Benefits of STAR®
No Waste Stream.
Adapts to variations in raw feed.
Sustainable recycled product.
Modular design. / Small footprint.
Consistent, reliable fly ash meets or exceeds all concrete specs.
The SEFA Group, a long time leader in the fly ash utilization industry, has developed a new, unique, and proprietary thermal beneficiation technology.
Staged Turbulent Air Reactor (STAR®) – The STAR® process is a thermal beneficiation 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 matter 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. The STAR® process also does not generate any solid waste stream and generates hot water as a by-product, which can be beneficially used by the Utility.
Benefits of STAR®
- No waste stream.
- Beneficial utilization of all product ash.
- Heat recovery from carbon.
- Adapts to variations in raw feed.
- Removes ammonia.
- Modular design.
- Small footprint.
- Eliminates negative effect on air entrainment.
- Sustainable recycled product.
- Consistent, reliable fly ash that meets or exceeds all concrete specifications.
The SEFA Group is proud to announce in early 2012 the opening of our new STAR® facility located in Newburg, Maryland, at the NRG Energy East Region Morgantown station. This new facility joins our existing McMeekin STAR® plant in Columbia, South Carolina.
Our proprietary thermal beneficiation process optimizes the quality of fly ash. With the introduction of the STAR® Refined Pozzolan into the region, concrete producers in this area now have access to the ultimate in thermally beneficiated fly ash.
