Scientists at Nanyang Technological University, Singapore (NTU Singapore) have pioneered a 3D concrete printing method that captures and stores carbon dioxide, marking a major step toward reducing the construction industry’s environmental footprint.
The innovative technique offers a promising solution to mitigate cement’s massive carbon emissions.
The process works by integrating CO₂ and steam—byproducts of industrial processes—into the concrete mix during 3D printing. As the material is printed, CO₂ reacts with components in the concrete, forming a solid, stable compound that remains locked within the structure.
