Two Finland-based companies are poised to scale carbon dioxide curing technology to precast concrete production the world over. The collaboration between product machinery and batch plant specialist Elematic Oy and CO2 utilization technology developer Carbonaide harnesses greenhouse gas chemistry to improve mix performance and accelerate precast element fabrication.
Since early 2024, Elematic and Carbonaide officials have observed the potential to reduce CO2 emissions associated with finished concrete by 50 percent using the technology, owing to lower portland cement requirements and CO2 mineralization in the concrete matrix. They also cite the potential for carbon-negative precast elements when their method is used with concrete mix designs bearing supplementary cementitious materials.
“CO₂ curing technology aligns perfectly with our commitment to delivering fast, sustainable, and cost-effective solutions for the precast concrete industry,” says Elematic CEO Teppo Voutilainen. “By integrating Carbonaide’s solutions into our systems, we can offer a practical solution that is both commercially viable and environmentally responsible.”
“Our collaboration is a significant step toward realizing the potential of CO₂ as a resource in the construction industry,” adds Carbonaide CEO Tapio Vehmas. “By incorporating our technology into Elematic’s advanced production systems, we empower precast concrete producers to deliver faster, stronger and greener products.”
