Finland-based Carbonaide, a spin-out company from the VTT Technical Research Centre of Finland, announced that it has secured €1.8M in a Seed round of funding.
The round was led by Lakan Betoni and Vantaa Energy, along with public loans and in-kind contributions from Business Finland and other Finnish concrete companies.
Carbonaide states that it plans to use the funding to incorporate its CO2 curing technology into the automated production line of its precast concrete factory in Hollola, Finland.
With its factory-sized pilot unit and fully operational value chain, the Finnish company can mineralize up to five tons of CO2 per day and increase production by 100-fold of its carbon-negative concrete products.
Carbonaide’s solution is based on an effective carbonation method, which binds carbon dioxide into precast concrete using an automated system at atmospheric pressure.
This technology has the potential to significantly reduce carbon emissions associated with traditional Portland cement concrete by minimizing cement content and mineralizing CO2 into the concrete.
By incorporating industrial side streams such as industry slags, green liquor dregs, and bio-ash into the binding process in place of ordinary cement, the outcome is concrete with a carbon footprint that is negative.
