Background

Taiheiyo Cement Corporation ("Pacific Ocean Cement Corporation") (太平洋セメント株式会社, Taiheiyō Semento Kabushiki-gaisha) is a Japanese cement company, formed in 1998 with the merger of Chichibu Onoda (itself a merger of Chichibu Cement and Onoda Cement) and Nihon Cement (formerly Asano Cement).

Chichibu Cement Co., Ltd. was founded in 1922. Kumagaya Factory was completed and began operations in 1962.

In April 2021, Taiheiyo Cement announced its plan to start a CO₂ capture demonstration project at the Kumagaya plant. It will use technology for CO₂ chemical absorption supplied by UK-based Carbon Clean. The project will have a capacity of 10t/day and demonstration tests will begin in September 2021. Taiheiyo Cement completed installations to demonstrate CO2 capture from kiln exhaust gas and the utilization of the captured CO2 in February 2022.
