SynopsisThe Cement 2 Zero project, a collaboration between key players in the steel and cement sectors, has successfully completed its first trial melt. This innovative project aims to develop the world's first industrial-scale zero-emissions cement. By using recycled cement as a flux in the electric steel recycling process, the project seeks to advance decarbonization efforts in construction, cement, and steel production. The project received £6.5 million in government funding and brings together organizations like the Materials Processing Institute, University of Cambridge, CELSA Steel UK, and more.ArticleIn a significant stride toward sustainable industry practices, the Cement 2 Zero project has achieved a groundbreaking milestone with the completion of its first trial melt. This collaborative initiative, involving key players from the steel and cement sectors, is poised to revolutionize the way cement is produced on an industrial scale, making it emission-free.The project's consortium comprises a diverse range of organizations spanning the supply chain. Partners include the Materials Processing Institute, University of Cambridge, CELSA Steel UK, Atkins, Balfour Beatty, Day Aggregates, and Tarmac. Each entity plays a pivotal role in research, development, scaling, and testing of this innovative process.The trial melt, a crucial step in this venture, was conducted using the Materials Processing Institute's seven-tonne Electric Arc Furnace (EAF) on its Teesside campus. This large-scale trial provided valuable insights into the process's feasibility.The Cement 2 Zero project, conceptualized by Dr. Cyrille Dunant at the University of Cambridge, leverages the chemical composition of used cement as a flux in electric steel recycling. The by-product of this process, when cooled and ground, yields Portland cement clinker that can be blended to create 'zero-emissions' cement.The pilot-scale EAF experiments utilize recycled cement as the flux material, processed by Day Aggregates and LKAB, an international mining and minerals group. Scrap steel inputs from CELSA are integral to the process. These trials aim to develop a deeper understanding of creating an industrial-scale end product.Tarmac is actively involved in testing the new clinker to evaluate its grinding properties and key performance criteria, while Balfour Beatty and Atkins are defining testing protocols and planning projects that will utilize the material produced in these pilot-scale EAF trials.The Cement 2 Zero project secured £6.5 million in funding from UK Research and Innovation (UKRI) as part of the Transforming Foundation Industries challenge.Chris McDonald, CEO of the Materials Processing Institute, emphasized the importance of this project's scale-up phase and its potential to contribute to the decarbonization of the construction, cement, and steel sectors.Carles Rovira, CEO at CELSA UK, expressed commitment to a Net Zero Pathway and circular economy principles, highlighting the significance of this collaborative venture.ConclusionThe Cement 2 Zero project marks a significant step toward revolutionizing cement production on an industrial scale, making it zero-emissions. This collaboration between key players in the steel and cement sectors represents a pioneering effort to advance decarbonization in these industries. With promising initial results, the project holds the potential to contribute significantly to a more environmentally friendly and resource-conscious manufacturing process, aligning with broader efforts to reduce carbon emissions.
