Carbonaide is taking the initiative to reduce carbon emissions through its innovative technology of turning CO2 into concrete blocks. This revolutionary technique can potentially absorb emissions, creating a carbon sink to capture CO2 and decrease the carbon footprint of various products manufactured with cement.

CEO Tapio Vehmas claims that this approach can reduce cement consumption in production and could generate negative footprinting results of -60 kg per cubic metre of concrete, compared to the conventional 250-300 kg per cubic metre.
How Does It Work?
VTT Technical Research Centre Finland's Carbonaide solution utilizes carbonation to attach carbon dioxide to precast concrete using an automated system operating at normal pressure. This reduces cement content, mineralizing CO2 into concrete and shrinking emissions by up to half.
By incorporating industrial byproducts like slags, green liquor dregs, and bio-ash in the linking process, it is able to create carbon-negative concrete that can permanently store and take out CO2 from the carbon cycle.
The team anticipates a 45% reduction in CO2 emissions during pilot-batch production in the autumn of 2022. Harri Vehmas, CEO of Carbonaide states that ‘the goal is to create a more sustainable future with revolutionary tech that traps more CO2 than it emits throughout its lifetime’ due to the sheer volume of man-made material construction projects generate.
Help To Bind 500 Megatons of CO2 By 2050
The concrete industry is accountable for 8% of global carbon emissions, leading to legislation encouraging construction materials that adhere to environmental laws involving carbon neutrality and reduced emissions.
VTT has devoted 80 years of research to the study of concrete structures; Carbonaide is a result of this exploration and has attained EUR 1.8 million in seed funding from Lakan Betoni, Vantaa Energy, and public loans from Business Finland among other Finnish concrete companies and investors.
The aid will facilitate the integration of CO2 curing technology into their precast factory in Hollola, Finland. With an ambitious goal of binding 500 megatons of carbon dioxide by 2050, corresponding with 10-20% of the current market share, Carbonaide intends to have ten operational units in the Nordics by 2026.
