§ Private Profile · Joensuu, Eastern Finland, Finland
Technology developer providing CO2 mineralization systems for precast concrete manufacturers, focused on reducing carbon emissions.
Based in Joensuu, Finland, Carbonaide develops automated carbonation technology that mineralizes carbon dioxide into precast concrete to reduce cement usage and lower industrial emissions. Founded in 2022 as a VTT spin-out by Tapio Vehmas, the company's atmospheric pressure system allows concrete manufacturers to integrate captured industrial waste, cutting carbon emissions by up to half compared to traditional Portland cement. Carbonaide plans to scale its operations to mineralize five tons of carbon dioxide per day at its Hollola factory, turning the built environment into a carbon sink. The enterprise has secured a €1.8 million seed round and a subsequent €3.7 million financing round from a syndicate of investors including Lakan Betoni, Vantaan Energia, Business Finland, and Redstone. Additionally, the firm partners with organizations like ARC in Copenhagen to integrate captured carbon emissions into sustainable concrete products.
Carbonaide has raised $10.8M across 3 funding rounds.
Carbonaide's curing method for concrete is designed to offer improved quality and lower production costs, in addition to reducing the carbon footprint of the materials.
Carbonaide's technology achieved commercial readiness in 2024, and its first client has been utilizing the system since then.
