Mathieu Neuville, CEO and Founder of MATERRUP: : "In 2014, when I left Total, I had a conviction that never left me:
clay — this resource we used to consider as waste — could become a major lever for decarbonizing the construction industry.
At that time, no one imagined turning these millions of tonnes of residual clay —
over 100 million tonnes per year in France alone —
into an industrial, certified and cost-effective product capable of competing with the world’s most widely used binders.
But to me, the potential was obvious. I could already envision a different kind of #cement — simpler, more resilient.
And, somehow, I could also see the products that could emerge from it.
The first one I dreamed of?
A render, a mortar — a ready-to-use geosourced solution accessible to all craftsmen
An everyday product, but fundamentally transformed at its core.
So we founded MATERRUP Low Carbon & Circular Cements with my brother Charles Neuville.
We built a laboratory with Manuel Mercé and later Julie Neuville, along with incredible teams — passionate and committed.
We spent years exploring the intimate mechanisms of clay.
Searching for the right path, the right process, the right balance.
Imagining a cement that would no longer rely on calcination, but on cold activation through a disruptive mechano-chemical approach.
This vision gradually took shape — first in early formulations, then in the first prototypes.
Then in the industrial tool.
And today, in thousands of tonnes of #MCC1® produced every year.
As this cement came to life, another idea was progressing in parallel:
how could we transform this cement into a bagged product capable of speaking directly to consumers, craftsmen, and distributors?
Today, that idea is finally emerging from the lab to become a commercial product:
Our first ultra-low-carbon mortar formulated from #MCC1®, designed for hollow block assembly.
A mortar conceived with the same rigor that has guided us from the beginning:
➡️ a geosourced raw material,
➡️a drastically reduced carbon footprint,
➡️ a stable, reproducible, controlled formulation,
➡️a product that is economically competitive,
➡️ and a user experience adapted to real-world construction sites.
This is a special milestone:
to see a material imagined more than ten years ago — conceived, designed, optimized, reformulated over and over —
become today a bag of mortar ready to be used.
This new product is not just a commercial launch.
It is the meeting point between a vision born a decade ago and the construction sites of tomorrow.
It is the first bag of a new generation of low-carbon solutions.
And another step toward an idea that has guided me from the very beginning:
to make clay useful, accessible, and transformative for construction."
