Pilot plant tests by the UK Quality Ash Association (UKQAA) have successfully demonstrated that Coal Derived Fly Ash (CDFA), found across the country in huge legacy stockpiles created by decades of electricity generation at power stations, can be processed to meet UK and European standards for use in cement and concrete. Developing these legacy stockpiles – estimated to be well over 100 million t – will also reduce the resource risk for the UK. “It’s exciting to see these two huge projects underway, because they illustrate the acceptance of fly ash development in the UK. For many years we’ve talked about the potential of fly ash, but now we’re seeing things coming to fruition. It is estimated that the two UK projects at Drax and Fiddlers Ferry could avoid around 500 000 tpy of CO 2 emissions from entering the atmosphere.
