Japan: Taiheiyo Cement has agreed to buy the cement business of chemicals company Denka for an undisclosed sum. Denka operates an integrated plant in Itoigawa City, Niigata Prefecture where Taiheiyo Cement’s subsidiary Myojo Cement also operates a plant. The three companies have been working on a joint-development plant for local limestone resources since 2018. However, Denka has decided to leave the cement market due to poor local demand and the necessity of upgrades at its plant from 2025 onwards.
From April 2023 cement sold from Denka’s Omi plant will carry the Taiheiyo Cement brand name. Taiheiyo Cement and Myojo Cement have also agreed to continue supplying Denka’s other businesses, such as carbide production, with limestone from 2025. Denka will send by-products and other waste streams to the cement producer. Finally, Taiheiyo Cement, Myojo Cement and Denka will carry on developing the local limestone resources near to Itoigawa City.
