3D-Printed Carbon Capture Technology

Researchers at Nanyang Technological University (NTU) in Singapore have unveiled an advanced 3D concrete printing technology that captures and stores carbon dioxide. This innovative process incorporates CO₂ into the building material, enhancing the strength and durability of the resulting structures.

The method involves injecting a mix of steam and carbon dioxide—both by-products of industrial processes—directly into the concrete as it is being printed. By embedding the CO₂ into the material, the process effectively locks the greenhouse gas within the structure, preventing it from re-entering the atmosphere.

Initial tests have shown that concrete produced through this technique exhibits superior mechanical properties, including enhanced strength when compared to conventionally 3D-printed concrete. This advancement could lead to more resilient and sustainable construction practices, helping the industry transition toward greener building solutions.
