- Advertisement -Carbonaide has raised €3.7 million to scale its carbon-negative concrete technology internationally and deepen its R&D push, as the construction sector races to decarbonise. Carbonaide has developed a commercially proven process that mineralises CO₂ into concrete during curing, permanently locking it away while improving material performance—turning concrete plants into carbon sinks rather than emitters. The CO₂ is permanently stored in the material, enabling concrete production that can be carbon-negative while remaining economically viable. This includes next-generation CO₂ curing technologies that could unlock use cases in ready-mix concrete and other concrete types. Earlier this year, Carbonaide also sold its first certified carbon credits generated through its mineralisation process to a Finnish law firm.
