Carbonaide has closed a new €3.7 million investment round as it ramps up commercialization of its carbon dioxide curing technology, which mineralizes CO₂ and stores it permanently in concrete. The Finland-headquartered company said the financing, a mix of equity and supporting financial instruments, will be used to expand operations and accelerate strategic initiatives to turn concrete production into a scalable carbon storage pathway.
The round was led by existing owners Vantaan Energia, Redstone, and Ihantola Invest, and included participation from private investment firms and investors, including Zero Carbon Future Group, Product Ecology Holding B.V., Helkama Kiinteistöt, and Ikorni Invest.
Carbonaide positions its process as a way to both improve concrete products and lock CO₂ into the material, targeting a sector under growing pressure to decarbonize. The company said the new capital will support international expansion, increase research and development for new applications, and advance efforts to make carbon-negative concrete commercially viable.
The funding is earmarked for three main priorities: strengthening global sales and marketing to drive customer acquisition, continued development of its Carbonaide Service Platform, and accelerated R&D beyond precast concrete. The cloud-based service platform is designed to manage CO₂ flows, carbon measurement, and carbon credit issuance. On the R&D side, the company said it is moving into next-generation CO₂ curing for concrete element production, with an eye toward future applications in ready mix and other concrete types.
Carbonaide said its technology has been in commercial production since 2024. In 2025, it signed agreements with Finnish concrete producer Lakan Betoni and concrete element manufacturer Lipa-Betoni to install Carbonaide systems in their factories, with production using those systems expected to begin in early 2026. The company also said it sold its first certified carbon credits tied to mineralization in January 2026.
KEY QUOTES
