FLSmidth forms ECOClay partnership to fully electrify clay calcination

27 April 2022, Published under Cement News

To further decarbonise the cement industry, FLSmidth and a series of leading industry experts have formed a new partnership called ECoClay TM . To reduce CO 2 emissions from cement production by up to 50 per cent, the ECoClay partners will develop and commercialise the technology needed to replace fossil fuels in the calcination of clay by fully electrifying the process.  Current clay calcination processes have gained momentum in recent years – especially with FLSmidth’s flash calciner sys...

Clay calcination – accelerating cement’s green transition

30 August 2021, Published under Cement News

With the cement industry’s goal of working towards saving the planet, FLSmidth proposes a simple switch: replace 30 per cent of clinker with calcined clay for up to a 40 per cent reduction in CO 2 emissions. In this article the company outlines why the move is not only smart and efficient but is something almost every cement manufacturer could do right now. By Steven Miller, FLSmidth, Denmark.
