Choosing Materrup materials means making a concrete, responsible choice today. Our low-carbon cements provide a ready-to-use, field-proven solution to reduce the environmental impact of the building sector, while preparing communities for tomorrow’s challenges.

MCC1® is produced in Saint-Geours-de-Maremne, in the Landes region of France. Entirely made from uncalcined clay sourced from local waste located less than 25 km from the plant, it demonstrates the maturity and efficiency of a circular, localized production model.

To strengthen this impact, Materrup is establishing local factories across France and Europe—bringing innovation closer to territories, creating jobs, and making sustainable materials more available and accessible to both professionals and private individuals.

Our solution combines tested performance, low-carbon impact, and cost competitiveness, while also offering a naturally light, warm beige-grey finish. Beyond aesthetics, this unique shade provides a functional benefit: its high albedo helps reduce urban heat island effects. In practice, our concretes already contribute to more sustainable, comfortable, and livable environments for everyone.
