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.
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 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 is the starting point for the material platform.
Electric multiwire cutting produces rock slabs and mineral fines at the same time.
Rock skins, fibre reinforcement and an insulating core form a new route to low-mass, high-performance building envelopes.
The CFR platform is being developed for structural beams, railway sleepers and other infrastructure applications.
Biogenic carbon can be stored inside the building while contributing to the wall's functional material architecture.
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.
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.
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.
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 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.
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.
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.
Environmental Research Letters, 2025. The assessed full-scale wall architecture combines three carbon-removal pathways: biochar, bio-based carbon fibre and enhanced rock weathering.
The DACCUSS house wall was also recognized as the JEC Composites Innovation Awards 2025 winner in Building & Civil Engineering.
01 BIOCHAR
Biogenic carbon stored inside the building.
02 BIO-BASED CARBON FIBRE
Carbon becomes structural performance.
03 GABBRO → ERW
Rock-processing fines enable additional atmospheric CO₂ removal.
Automated manufacturing. Certification. Demonstration projects. Strategic capital. The objective is not a niche carbon-removal product, but a globally scalable structural-material platform.

The information on this website provides an overview of TechnoCarbonMaterials, CarbonFiberRock (CFR), Enhanced Rock Weathering (ERW), and related research and development activities.
Technical data, environmental-performance data, carbon-removal statements and descriptions of potential agricultural effects reflect the respective state of research and development. Results may depend on material properties, site conditions, transport, application, measurement, reporting and verification, further scientific validation, certification and regulatory requirements.
References to mineral fines as ERW feedstock mean that an extremely fine mineral fraction is generated as a co-product of structural-rock processing. This does not imply that downstream ERW activities are cost-free. Material characterization and conditioning, drying where required, transport, field application, monitoring, reporting and verification, and other region-specific processing may be required.
No representation or warranty is made that research results, development targets or future commercial performance described on this website will necessarily be achieved in every application.
