Taiyo Nippon Sanso Corporation cooperated with Taiheiyo Cement Corporation in the CO₂ liquefaction process for the “Development of Carbon Circulation Technology for the Cement Industry” project of NEDO. In February 2022, the company established a CO₂ liquefaction system at Taiheiyo Cement’s Kumagaya Plant. The system will recycle CO₂ emitted in the cement manufacturing process as a resource for reuse as raw material for cement and civil engineering material. Taiyo Nippon Sanso provided technical collaboration on a series of processes for liquefaction of captured CO₂ in a trial demonstration of separating and capturing CO₂ from cement kiln exhaust gas.
