UK: The Cement 2 Zero project has successfully concluded its first trial melt of recovered cement paste in an electric arc furnace at the Materials Processing Institute’s Teesside campus. The project uses the paste as flux for electric steel recycling. Cambridge Electric Cement (CEC) has demonstrated that the ‘slag’ from this process can be ground into fine clinker that, when mixed with gypsum and supplementary cementitious materials (SCMs), produces net zero CO₂ cement. The Cement 2 Zero project to produce CEC’s cement at an industrial scale launched in March 2023, with US$7.85m in funding from UK Research and Innovation. Tarmac will grind the clinker from the project’s trial melts for testing in order to obtain certification and specification as a usable cement product.
