University of Cambridge researchers have developed a method to produce very low-emission concrete at scale, which they describe as “an absolute miracle” that could prove key in the drive to net zero. The Cambridge Electric Cement process uses electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, which is responsible for almost 90 per cent of the emissions from concrete. Scaling rapidly, the method could be used to create one billion tonnes per year by 2050, which represents roughly a quarter of current annual cement production, the researchers say. Accoun…
