US: National Cement is upgrading its Lebec cement plant in California to make it carbon neutral. The upgrade involves a transition to limestone calcined clay cement (LC3) production. The producer will also substitute fossil fuels with locally-sourced biomass, including pistachio shells, in cement production. Lastly, a carbon capture installation will remove 950,000t/yr of CO₂ from the plant’s flue gases.

France: Lafarge France has ignited the new kiln at its Martres-Tolosane cement plant following a Euro120m upgrade. Local press has reported that the upgrade replaced the plant’s existing kilns and preheater tower with entirely new equipment. The new kiln has tripled the plant’s capacity, to 2.1Mt/yr from 0.7Mt/yr. Meanwhile, the new preheater tower will help to reduce the plant’s electricity consumption by over 20%. As a result of the upgrade, the Martres-Tolosane plant can now support an alternative fuels (AF) substitution rate of 60%, compared to 20% beforehand. Lafarge France aims to carry out further work to reach 85% AF substitution at the plant by 2027. Other planned projects include the installation of a carbon capture system.

Lafarge France CEO François Petry said “We are going to create a research and innovation centre here dedicated to the capture of CO₂, with the ambition of ultimately making the Martres-Tolosane plant net zero carbon.”

Sweden: Cementa plans to increase the share of bio-based alternative fuel (AF) in its Slite, Gotland, cement plant’s fuel mix. The move forms part of the plant’s plan to achieve climate positive cement production from 2030.

Parent company HeidelbergCement’s Northern Europe general manager Giv Brantenberg said “As we capture and store CO₂ from the cement production, including emissions from bioenergy, we will be able to manufacture carbon-free cement for the Swedish construction industry.”

UK: Germany-based HeidelbergCement’s subsidiary Hanson Cement will be the subject of a study in the use of biomass and hydrogen fuels coordinated by the Mineral Products Association. The Department for Business, Energy and Industrial Strategy is funding the Euro3.81m study, the results of which it says will be shared across the cement industry. HeidelbergCement CEO Dominik von Achten said, "In addition to our activities in the field of carbon capture, use and storage (CCUS), this project is an important step towards realising our vision of carbon-neutral concrete by 2050.”
