Steel production in Port Talbot, Wales is set to change forever in the coming weeks. On Monday, Tata Steel is expected to end production in the last remaining blast furnace in the area, marking the end of traditional steel production in South Wales. The move comes as part of a restructuring programme that will result in 2,800 job losses. This pivotal moment in Welsh steelmaking can be traced back to the declining fortunes of primary steelmaking and its reliance on carbon-emitting blast furnaces.
The shutdown of the blast furnace marks a turning point for one of the birthplaces of the industrial revolution. Geraint Williams, a professor at Swansea University, explained how this closure, and the predicted end of the UK’s last remaining blast furnaces in Scunthorpe, signals a significant change in the country’s industrial history. Williams stated that the UK is losing the capability to produce its own primary steel, calling blast furnace closures “a turning point in steelmaking”.
Despite this, Tata Steel UK is investing in an electric arc furnace to reduce emissions and ensure the long-term future of steelmaking in Britain, with the UK government investing £500m towards the cost of this technology. Construction of the electric arc furnace is set to begin in August 2025. However, in the short term, steelmaking in Port Talbot will rely on imported steel slab stock to supply customers and Tata’s downstream sites in Trostre, Llanwern, and Shotton.
The end of primary steel production in Port Talbot will have an emotional impact on employees, and Owen Midwinter, who hails from the area, is one of them. Speaking about his departure from the blast furnace control room, Midwinter expressed a desire to stay with Tata. However, uncertainty surrounding job reallocation has been playing on his mind, with Midwinter accepting he may have to move away “to find the kind of work he wants”. He also spoke of the acceptance and mixed emotions amongst his colleagues at the plant, saying that some employees have been there “for years and years” and feel the weight of the closure more.
Blast furnaces, the traditional primary steelmaking method, produce molten iron by splitting rocks containing iron ore. Achieving this reaction requires intense heat. While primary steelmaking emits high levels of carbon into the atmosphere, it can extract iron from its original source. Once purified, it can be treated to make all types of steel. However, electric arc furnaces recycle steel by melting it down and do not produce primary steel. As such, the production switch represents a significant change for the UK steel industry
