Soliciting Support from UK Government to Safeguard Legacy Stockpiles of Coal Derived Fly Ash (CDFA) Authors Dr. Nigel Cooke - United Kingdom - UK Quality Ash Association Abstract The global environment is under the spotlight and the need to reduce greenhouse gases is having a profound impact on just about every industrial sector. The construction industry is no exception. Coal derived fly ash (CDFA), has long been accepted within the UK construction sector for the unique properties it imparts to concrete and mortars and as a secondary aggregate for use in autoclaved aerated block manufacture and grouts. With a goal of zero net carbon by 2050, the environmental benefits of CDFA are becoming of much greater significance. With coal fired power production expected to cease in the UK by end 2024 , fresh supplies of CDFA will cease. As a consequence, future demand will need to be met through imports together with exploring the technical and commercial viability of extracting and processing CDFA from stockpiles. The UKQAA has identified >100 million tonnes of CDFA within single use deposits located at currently operating and recently closed coal fired power stations. Such deposits are, however, identified as a waste making it very difficult to gain planning permissions for subsequent extraction. The UKQAA spent 3 years liaising with key Government departments to develop understanding of the long term strategic value of CDFA for the construction sector and the need to safeguard them for future generations. The UKQAA brought together planning experts, users of CDFA, owners of legacy stockpiles of CDFA, technology companies and the University of Dundee to develop support to safeguard these deposits. This also involved developing terminology that could be used in Government planning policy documentation. The result of these efforts resulted in support from key government departments including planning, environment and industrial strategy. The need to safeguard CDFA is now referred to in the latest edition of the National Planning Policy Framework.
