Beneficial use of Fly Ash: An environmental win for water, CO2 and energy savings

The beneficial use of ash is a great way to reduce landfill disposals and to remove ash from ash ponds. Santee Cooper has recycled more than 325,000 tons of fly ash from Cross Generating Station in 2015 and... Continue Reading >>
