In Finland, carbon dioxide curing technology developer Carbonaide Oy has hosted the grand opening of the commercial implementation of its proprietary technology at the Lakan Betoni concrete manufacturing facility in Joensuu. The new facility demonstrates that its carbon dioxide utilisation and mineralisation technology is economically viable and ready to operate at an industrial scale, showcasing how concrete manufacturers can utilize and store carbon dioxide while producing durable, low-carbon concrete with an optimized carbon footprint.
During the opening ceremony held on March 6, 2026, Finland’s Minister of Economic Affairs, Sakari Puisto, emphasized that increasing expectations for low‑carbon building materials will guide the development of the construction sector.
Lakan Betoni’s investment in new technology sets an important example. It demonstrates a willingness to renew operations and take actions towards long‑term competitiveness. The significance of the investment extends beyond a single company, Minister Sakari Puisto said.
According to Minister Puisto, the new production line serves as a showcase for Finnish high‑technology capabilities, strengthening Finland’s position among countries seeking fast and scalable ways to reduce emissions from the construction sector.
Being able to present solutions in a functioning factory in an industrial setting increases credibility in the market much more than just demos and pilot projects, Minister Sakari Puisto added.
Cheaper, faster, stronger low-carbon concrete
The Carbonaide solution enables concrete manufacturers to utilize carbon dioxide and permanently store carbon as carbonates, achieving immediate emission reductions while improving mechanical properties and increasing production capacity.
CO2 curing strengthens concrete through controlled CO2 mineralization, reduces the need for cement, and lowers greenhouse gas (GHG) emissions, allowing producers to store carbon dioxide permanently in the building and construction environment.
Operational, scalable, and proven technology
The Lakan Betoni Joensuu facility is the first site where Carbonaide’s complete CO2 concrete curing system, CO2 flow management, and software platform operate together as a one‑stop solution.
The plant integrates the mineralization process directly into everyday concrete production.
For customers, the commissioning of the Joensuu facility provides a real‑world reference environment in which the entire ecosystem, from CO2 partner network to carbon credit management, is running at full industrial scale.
