Installation of CO2 Liquefaction System for Demonstration Trial
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.
