Carbonaide and NeoCarbon cure concrete with direct air captured CO2

Finland/Germany: Finland-based Carbonaide has cured 1kg of concrete with CO₂ captured using NeoCarbon’s direct air capture (DAC) method. The partners blended the CO₂ with other CO₂ from biogenic sources. They said that the project, called NeoDuo, successfully demonstrated concrete production with 50% reduced CO₂ emissions, and can also be used to produce carbon-negative concrete when cement is substituted with alternative binders.

The companies plan to scale this technology to achieve 1000t of CO₂ sequestered by 2026. They are reportedly on track to begin providing carbon removal credits to customers later in 2025.
