Taiheiyo Cement, JFE Steel and the Global Institute for Environmental Technology researching producing carbonates from steel slag

Japan: Taiheiyo Cement, JFE Steel and the Global Institute for Environmental Technology are working together to develop a carbon capture and storage system. The system will use wet alkaline earth metals extracted from steel slag to produce carbonates from exhaust gases at cement and steel plants. The partners are investigating the possibility of using these carbonates, specifically calcium carbonate and magnesium carbonate, as additives in cement production at Taiheiyo Cement’s plants. Taiheiyo Cement president Masafumi Shigehara said, “With the effects of climate change becoming apparent both in Japan and overseas, the importance of global warming counter-measures is increasing.”
