Trials complete on pilot Electric Arc Furnace

The UK-based Materials Processing Institute has recently completed successful trials of its pilot Electric Arc Furnace (EAF) for the UKRI Cement2Zero project. The trials have been developing and testing the use of end-of-life cement as an EAF flux to produce steel, whilst also capturing the slag to produce clinker to manufacture zero-emissions cement. The trials began in September 2022 and involved 12 induction furnace trials and eight trials in the Institute’s 7t EAF.

Research has shown that Portland cement can be made from recycled cement in an EAF during the steel recycling process. The Cement2Zero project will now demonstrate this process on an industrial scale.
