France: Vicat started using a CO₂ntainer system supplied by UK-based Carbon8 Systems at its Montalieu-Vercieu cement plant in November 2020. It uses captured CO₂ from the unit’s flue gas emissions to carbonate cement-plant dust and produce aggregate, which can then be used to make products such as concrete. The system has particular relevance for a plant burning alternative fuels due to the additional chlorinated dust created compared to the use of conventional fossil fuels. The company says it is the first European cement producer to use the process at an industrial scale. Previously, Carbon8 Systems said that its CO₂ntainer would process and convert up to 12,000t of cement bypass dust in its first phase of operation.

Vicat Group scientific director Laury Barnes-Davin said, “We were drawn to Carbon8 Systems’ two-part technology: capturing the CO₂ that Montalieu emits, and using it to produce an aggregate that can be marketed in the construction industry. It opens up great potential for our operations not just in France but also in all the countries where we work across the globe.” The group hopes to reach a 100% alternative fuel substitution rate in France by 2024.
