CO₂-NEGATIVE
Next-generation CO₂-negative cement
Why Karbonite?
Certified CO₂-Negative Performance
Karbonite permanently sequesters up to 143 kilograms of CO₂ per ton during production—verified through independent analysis. This is not offsetting, but real, verifiable carbon removal embedded in the material itself.
Eligible for Carbon Credit Revenues
Because of its net-negative carbon footprint, Karbonite is eligible for registration under international carbon credit frameworks. Projects using Karbonite can generate additional revenue through the sale of verified carbon credits—up to 140 kg CO₂ per ton, depending on the energy source used.
No Freshwater or Natural Sand Required
Karbonite replaces conventional raw materials with olivine, lignin, and cellulose—abundant, sustainable inputs that eliminate the need for freshwater and river sand. This makes it highly scalable in resource-constrained environments.
Up to 50% Lower Energy Use
Karbonite requires only 132 kilowatt-hours per ton of cement produced, consuming less than half the energy of traditional Portland cement. The process is optimized for compatibility with renewable energy sources such as solar, wind, and biogas.
Why Karbonite?
Structural-Grade Performance
With compressive strengths exceeding 60 megapascals, Karbonite meets and surpasses the structural requirements for modern concrete applications, including infrastructure and multistory buildings.
Built-In Thermal Insulation
With a thermal conductivity of just 0.35 W/m·K, Karbonite enhances the energy efficiency of buildings, reducing heating and cooling demand and contributing to long-term operational savings.
Protected by International Patents
The technology behind Karbonite is secured through three international patents, enabling exclusive licensing models in strategic regions and protecting long-term market advantage.
Independently Validated
Karbonite’s performance, durability, and CO₂-negative credentials have been independently validated by SGS and Imperial College London.

About Us
innovative, environmentally friendly cement
Karbonite (Green Eco Circular Cement) is the world’s first truly CO₂-negative cement. Using activated olivine and biomass residues from biorefineries, it redefines what sustainable construction can be. Each ton of Karbonite removes a net 143–178 kg of CO₂ from the atmosphere, qualifying it for verified carbon credit generation and ESG reporting. This innovation offers both environmental benefits and financial incentives for builders, governments, and investors.
Why Karbonite?
The Innovation That Sets It Apart
Energy Efficiency
Karbonite is produced at just 800°C, consuming only 132 kWh per ton – 50% less than Portland cement. This significantly lowers energy costs and Scope 1 emissions.
CO₂ Removal & Certification
Unlike any other cement, Karbonite absorbs more CO₂ than it emits. It qualifies for carbon credit certification under standards like Verra, Gold Standard, and the EU ETS. Up to 178 kg of CO₂ credits can be claimed per ton produced – creating direct value per project.
Lower Costs, Lower Emmisions
Karbonite is at least 21% more cost-efficient than traditional cement. It also avoids carbon taxes and qualifies for green finance due to its alignment with CSRD and ESG frameworks.
No Clean Water or Natural Sand
No freshwater or high-grade sand is needed. Karbonite uses seawater or ditch water and integrates biogenic materials like lignin and cellulose. This eliminates costly and unsustainable extraction, transport, and permitting processes.
Performance & Longevity
Karbonite matches or exceeds the compressive strength of traditional cement (up to 60+ MPa) and continues to harden in CO₂-rich environments. Freeze-thaw testing confirms high durability — with a technical lifespan of 70–90 years.
Vision
Where Performance Meets Sustainability
Karbonite is versatile and suitable for a variety of construction applications, including:
Concrete Structures
Ideal for structural components such as foundations, walls, and beams. Karbonite offers excellent compressive strength and enhanced thermal insulation, reducing energy loss in buildings. With a lifespan of 70–90 years, it far outperforms traditional Portland cement in durability and long-term resilience.
Infrastructures & Asphalt
Used in road bases, asphalt concrete, and sublayers, Karbonite enhances freeze-thaw resistance and extends the functional life of infrastructure. Its inherent insulating properties reduce thermal cracking, while its longevity lowers maintenance and replacement costs over decades.
Paving Stones & Bricks
Perfect for applications with lower compressive strength requirements like curbs, tiles, and pavers where Karbonite delivers maximum CO₂ reduction per ton. These elements benefit from increased resistance to temperature fluctuations and have a significantly longer service life than conventional products.
