PMI Ash Technologies, LLC (PMI), provides economic ash management solutions through innovative technology. The Carbon Burn-Out (CBO) process eliminates fly ash disposal while creating a high-quality pozzolan for use in concrete. In addition to addressing solid waste issues, Carbon Burn-Out recovers residual carbon's valuable heat, measurably increasing the host utility's generation efficiency.

PMI's Carbon Burn-Out process is currently online at South Carolina Electric & Gas Wateree Station, Santee Cooper's Winyah Station, Dominion Energy Brayton Point Station, and Dominion Virginia Power Chesapeake Energy Center. The technology has been commercial since 1999 and has a combined processing capacity of approximately 1 million tons per year.

PMI also manages ash at the Crystal River plant in Florida. It produces a medium weight aggregate called Aardelite®. The aggregate is used by customers in producing concrete masonry units and structural concrete that meets or exceeds all applicable standards. Overall fly ash utilization at Crystal River has averaged over 85% for the past 20 years.
