Description
The global imperative to reduce greenhouse gas emissions is reshaping industrial strategies across all sectors, with construction facing particular scrutiny due to its significant embodied carbon footprint. In response, greater emphasis is being placed on proven materials that can deliver both performance and environmental benefits. Coal-derived fly ash (CDFA) has a long and successful history within the UK construction sector. It is widely recognised for the technical advantages it brings to concrete and mortar performance, as well as its established use in applications such as autoclaved aerated concrete, grouts, and secondary aggregates. As the UK commits to achieving net-zero carbon by 2050, the role of CDFA as a lower-carbon supplementary cementitious material is becoming increasingly important. With the cessation of coal-fired power generation in the UK in 2024, attention has shifted from freshly produced ash to the sustainable recovery and processing of legacy ash stockpiles, supplemented where necessary by imports. In this context, the UKQAA has identified in excess of 100 million tonnes of coal-derived fly ash contained within single-use deposits at operational and recently closed power stations across the UK. Recent developments in 2025 mark a significant turning point, with major investment announcements for new ash processing facilities, including projects at Drax Power Station and Fiddlers Ferry. These investments signal renewed confidence in the long-term availability and strategic value of CDFA within a decarbonising construction sector. This presentation will provide an overview of the UK market context, the drivers behind recent investment decisions, and the emerging outlook for coal-derived fly ash in the UK. It will also set the scene for further technical discussions on ash processing technologies and site-specific developments.

Coal-Derived Fly Ash – The Outlook Is Bright in the UK
