Building materials × carbon removal

ONE PROCESS.
TWO VALUABLE OUTPUTS.

CarbonFiberRock — CFR turns one rock-processing step into two material streams: structural slabs for buildings and infrastructure, and mineral fines as feedstock for Enhanced Rock Weathering.

STRUCTURAL ROCK + CDR FEEDSTOCK — CREATED IN PARALLEL.
A new material architecture

Climate doesn't need a better concrete. It needs a new material system.

CFR combines the compressive performance of natural rock with fibre reinforcement to create lightweight structural elements for buildings and infrastructure.

The scaling principle: we do not need to invent a new global material stream. Rock already scales. Construction already scales. We change what we build with.

The industrial synergy

Cut the rock once. Create two valuable outputs at the same time.

The slabs are the construction product. The mineral fines arise in the same cutting process. With suitable silicate rock, those fines can become ERW feedstock — without a separate dedicated grinding step to create this fraction.

Hard-rock quarry

Hard rock is the starting point for the material platform.

Multiwire stone cutting machine

Electric multiwire cutting produces rock slabs and mineral fines at the same time.

01 — Building

Carbon removal becomes part of something society needs anyway.

FULL-SCALE

Structural wall systems

Rock skins, fibre reinforcement and an insulating core form a new route to low-mass, high-performance building envelopes.

STRUCTURE

Beyond walls

The CFR platform is being developed for structural beams, railway sleepers and other infrastructure applications.

CARBON STORAGE

Biochar integration

Biogenic carbon can be stored inside the building while contributing to the wall's functional material architecture.

02 — ERW + Agriculture

The CDR feedstock emerges while we make the building product.

Producing structural rock slabs simultaneously creates mineral fines. With suitable silicate rock such as gabbro, this co-product can be used as feedstock for Enhanced Rock Weathering (ERW).

This changes the economics: the rock is already being processed to create a valuable construction product. The cutting process already generates an extremely fine mineral powder, so this fraction does not require a separate rock-grinding chain simply to be created.

But the powder is the starting point — not the end of the ERW process. Depending on the rock, region and application, downstream steps can include characterization and conditioning of the powder, drying where required, transport, field application, and monitoring, reporting and verification (MRV) of the resulting CO₂ removal.

Finely divided silicate rock applied to soils accelerates natural weathering reactions that consume atmospheric CO₂. The photographs below show our practical application of gabbro rock powder together with biochar in Rwanda.

One process. Two markets.

The building product carries the rock-processing economics.

The same cutting step creates the structural slabs and the mineral fines. That makes the ERW feedstock a co-product of construction-material production rather than the sole product that must carry the upstream processing burden.

From application to evidence

Real-world use. Scientific evaluation continues.

The field photographs document application, not a claim of proven crop-yield improvement. Long-term soil and agronomic effects remain subject to scientific analysis.

For TechnoCarbonMaterials, the key systems insight is the parallel production itself: structural slabs create commercial value while mineral fines emerge from the same processing step and can be directed toward a second climate application rather than treated as waste.

03 — Science & Research

Global scale requires local rock.

Enhanced Rock Weathering is a mass-material solution. Moving heavy rock over long distances adds cost, energy demand and transport emissions. Our research mission is therefore local by design: identify locally available igneous rocks that can perform for both construction and carbon removal.

The research challenge

Which local rock works best for both?

The best rock is not simply the rock with the highest theoretical CO₂-removal potential. We investigate which locally available igneous rocks combine structural performance, efficient cutting and processing, suitable mineral fines, local soil requirements, weathering potential and measurable net carbon removal.

01 MATCH THE ROCKMap local geology and characterize mineralogy, chemistry, structural quality and cutting behaviour.
02 CREATE VALUEUse the structural fraction as slabs for CarbonFiberRock buildings and infrastructure while ultra-fine mineral powder emerges from the same cutting process.
03 PREPARE LOCALLYCharacterize and condition the powder for regional use — including drying or further processing where required.
04 DEPLOY & MEASUREOptimize transport, field application and agricultural integration, and develop robust monitoring, reporting and verification of actual CO₂ removal.
05 OPTIMIZE THE SYSTEMMatch local rock, soils, climate, crops, infrastructure and energy systems to find the best regional Building + ERW pathway.
Regional materials matching

LOCAL GEOLOGY → STRUCTURAL PERFORMANCE → PROCESSING → ROCK POWDER → LOCAL SOIL & CLIMATE → ERW → MRV

The objective is not to identify one “perfect” rock and transport it around the world. Basalt and related igneous rocks are widely distributed. The opportunity is to develop a transferable scientific methodology for finding the best locally available combination of rock, construction application, agriculture and carbon removal in each region.

One global platform. Many local rocks.

Global scaling requires regional science.

We don't need to find the world's best rock. We need to find the best local rock for each region.

This requires a major international research effort combining geology, structural engineering, mineralogy, soil science, agronomy, weathering kinetics, logistics and carbon-removal MRV.

From evidence to scale

The next challenge is industrialization.

Automated manufacturing. Certification. Demonstration projects. Strategic capital. The objective is not a niche carbon-removal product, but a globally scalable structural-material platform.
