France: Lafarge France, part of Holcim, will increase production of activated clay cement to 1.1Mt in 2026 after surpassing 0.6Mt in 2025. The cements incorporate up to 22% activated clay (CEM IV/A) to reduce clinker content and CO₂ emissions while maintaining technical performance, according to the company.
Production of activated clays began in 2022 at its La Malle site and expanded in early 2023 with a dedicated line at Saint-Pierre-la-Cour using the proximA Tech process. Lafarge plans to build a second activated clay production line at Saint-Pierre-la-Cour under the Capt4Climate project, supported by the French government. The facility will become operational in 2029 and will triple the site’s capacity.
