About H2

This new production unit, still on our historic site in Bournezeau (Vendée), marks an important step in the company's development. This plant, unique in the world, is a concrete example of our industrial vision: cutting-edge technologies, advanced R&D and human collaboration to offer solutions to environmental issues.
We believe in the virtues of the industry to meet today's challenges. It took us less than 4 years to move from the idea to our first plant (inaugurated in 2018). By 2024, we will have increased our production capacity from 50,000 tonnes to 550,000 tonnes per year with the construction of two new plants: H2 in the Vendée and H3 in the Île-de-France region.
This new plant model will allow us to move from an industry with a high environmental impact to a desired industry, at the cutting edge of technology and at the service of environmental issues.

About H2

The H1 production unit has enabled us to test, calibrate and optimise our manufacturing processes on a large scale. H2, will enable us to go further and multiply our production capacity by 5 compared to our pilot plant. This new plant is therefore the model that we are going to deploy in the regions, the result of a multitude of challenges: inventing a large-scale production process for our cements, combining industrial performance and minimum impact, combining industrial production capacity with a small footprint to set up near cities. It's an incredible adventure carried out at high speed. It is a collective pride to imagine this plant of the future.
