carbocleartech project
CarboClearTech is a carbon capture and storage system that will be installed at Holcim’s cement plant in Martres-Tolosane in the Occitanie region of France.
The plant is already one of the most modern in France, thanks to recent investments totaling €124 million. Now, the European Union (EU) Innovation Fund has selected CarboClearTech to receive a grant from a pool of €4.8 billion.
From 2025, the plant will also host an open innovation platform where researchers, start-ups, companies and other innovators can test new carbon capture technologies at scale.

The technology behind the project
CarboClearTech will sequester 700,000 tons of residual CO2 emissions that would otherwise be released into the atmosphere. It will enable the entire plant to reach net-zero by 2031. Today, the plant accounts for 4% of France’s total cement production. Its decarbonization will accelerate the move toward decarbonized construction.
CarboClearTech was developed in partnership with a world leader in industrial gases. The first CO2 capture site in Southwestern Europe, it brings this vital technology to the region and contributes to its green growth.


As the first CO2 capture facility in Southwestern France, and also in Southern Europe, CarboClearTech is giving the impetus needed to develop new decarbonized sectors, which are essential for the future of European industry.
