Decarbonization, competitiveness, and local sourcing.

Mathieu Neuville, CEO and Co-founder of Materrup : 
"The cement industry has never had to solve three constraints simultaneously: decarbonization, competitiveness, and local sourcing.

A single process addresses all of them.

We made the same choice as the pioneers of lithium-ion batteries: go back to the physics, don't optimize the existing.

The result: #MCC1®. A certified class 42.5 cement, produced cold, without a kiln, without flame, without gas. Not a lab demonstration. A cement delivered to 1,000+ construction sites since 2022

The thermal equation is closing in

Gas between €25 and €40/MWh. Refractory maintenance. Gas treatment. And +$10/bbl on Brent that mechanically translates to +€1.5 to 3/t — with no absorption lever whatsoever.

Meanwhile, alternatives have shown their structural limits: insufficient early-age strengths, prohibitive #CAPEX, dependence on industrial by-products whose reserves are drying up.

This is not a cyclical crisis. It is a model obsolescence.

What we have built.

Our proprietary CCC® Technology — cold mechanochemical activation — transforms a local clay waste (quarry tailings, excavated material, washing fines, sediments, clay-limestone sludge) into a high-performance reactive mineral addition.

Activity index: 90 to 110% per EN 450-1.​

From this #SCM comes MCC1®, a certified class 42.5 cement.

Process figures, compared to flash calcination:

⚡ ≤ 60 kWhe/t — vs. 523 to 700 kWheq/t

💶< €10/t energy cost — vs. €22 to €36/t depending on Bren

🏗️CAPEX 3 to 12× lower than flash calcination lines

🌿 ~25 kg CO₂/t process — vs. 95 to 200 kg in thermal

📍 Supply chain < 25 km — local waste, zero import dependency

At price parity with conventional cement. No subsidy. No integrated carbon credit. Economic performance alone.

What the industry has not yet absorbed.

Every quarry operator, every earthworks site, every dredging contractor manages a clay deposit — and bears its cost. This stream is now industrially valorizable, at scale.

This is exactly what the first ones to bet on lithium-ion batteries understood before everyone else.

Where we stand.

Saint-Geours-de-Maremne site (Landes, France) operational since 2022.

1,000+ construction sites supplied. 100+ international patents

Four new sites in deployment.

We are no longer in the validation phase.

We are in the industrial deployment phase — with the learning curves that come with it.

#RMC producers, precasters, builders, and #civil engineering contractors are today looking for a local, competitive, and low-carbon cement — without any compromise on performance.

That cement exists.

It has been produced in France since 2022."
