Concrete is one of the world’s most widely used construction materials, but also one of the largest contributors to global carbon emissions. Finnish startup Carbonaide is aiming to change that equation by turning concrete production into a carbon sink rather than a source of emissions. The company has now raised €3.7 million in new funding to accelerate the international rollout of its carbon dioxide curing and permanent CO₂ storage technology.
Carbonaide’s solution has already moved beyond the pilot stage. Its technology has been in commercial production since 2024, marking a significant milestone in the shift from experimental carbon capture concepts to deployable industrial systems.
Industrial Partnerships Drive Commercial Scale
In 2025, Carbonaide signed agreements with two major Finnish concrete companies, Lakan Betoni and Lipa-Betoni, to integrate its technology into their production facilities. Installation work is underway, and both factories are expected to begin production using Carbonaide’s systems in early 2026.
These partnerships represent a crucial step in validating the technology at an industrial scale. By embedding carbon dioxide curing directly into existing concrete manufacturing processes, Carbonaide enables producers to reduce emissions while maintaining performance and cost efficiency.
First Certified Carbon Credits Achieved
At the beginning of 2026, Carbonaide reached another important milestone by selling its first certified carbon credits generated through mineralisation. This achievement demonstrates that the company’s process not only reduces emissions but also enables verifiable and permanent CO₂ storage.
The ability to issue certified carbon credits adds an additional revenue stream for both Carbonaide and its customers, reinforcing the commercial viability of carbon negative concrete solutions.
Strong Backing From Existing and New Investors
The funding round was led by Carbonaide’s existing shareholders Vantaan Energia, Redstone, and Ihantola Invest. They were joined by several new private investment firms and investors, including Zero Carbon Future Group, Product Ecology Holding B.V., Helkama Kiinteistöt, and Ikorni Invest.
Panu Pasanen, CEO of One Click LCA and an investor through Zero Carbon Future Group, highlighted the significance of the technology’s readiness for scale. He noted that Carbonaide’s approach aligns with the growing demand for accurate carbon data and low carbon building materials in the construction industry.
Funding Priorities and Platform Development
The newly raised capital will be directed toward three main areas of growth. First, Carbonaide plans to strengthen its global sales and marketing efforts to expand customer acquisition beyond its home market.
Second, the company will continue developing its Carbonaide Service Platform, a cloud based system designed to manage CO₂ flows, track carbon measurements, and support carbon credit issuance. This platform is intended to become the operational backbone of Carbonaide’s offering, enabling transparency and scalability across multiple facilities.
Third, Carbonaide will accelerate research and development beyond precast concrete. The next phase of its roadmap focuses on next generation carbon dioxide curing for concrete element production, with longer term ambitions to expand into ready mix concrete and additional concrete applications.
Turning Concrete Factories Into Carbon Sinks
According to CEO Tapio Vehmas, the company’s momentum reflects a broader shift within the construction sector. He emphasised that there is growing demand for solutions that reduce emissions without compromising performance or profitability.
Vehmas added that Carbonaide’s goal is to transform concrete factories into permanent carbon sinks while supporting the industry’s transition toward a low carbon built environment.
With commercial deployments underway, certified carbon credits already issued, and fresh capital secured, Carbonaide is positioning itself as a key player in the next generation of sustainable construction materials.
