Circular Solutions for 3D construction Printing: Low-Carbon Concrete and 3D Printing Houses

The construction industry, accounting for a substantial 35% of waste and 40% of global carbon emissions, faces the imperative of transitioning to sustainable practices to achieve carbon neutrality by 2060 amidst escalating population growth and housing demands. 3D Construction Printing (3DCP) emerges as a viable solution, capable of reducing the carbon footprint by utilizing low-carbon materials, particularly crucial in addressing housing shortages. Although some pioneering projects in the USA, Europe, and Canada have utilized 3DCP with high-carbon materials, the lack of custom-made, low-carbon materials tailored to specific regional needs poses a challenge. This research initiative aims to leverage sustainable additive manufacturing and circular economy principles to develop low-carbon materials for 3D printing housing, utilizing waste and recycled resources. Overcoming challenges related to material reactivity and maintaining performance indicators, the success of this endeavor could not only benefit the 3D construction printing sector globally but also contribute to decarbonizing the broader concrete industry as global demand for concrete continues to rise.
