MIT Concrete Sustainability Hub White Paper


When paired with ICON’s wall system and robotic construction methods, ICON’s CarbonX formula is the lowest carbon residential building system ready to be used at scale. A white paper co-authored with the MIT Concrete Sustainability Hub, “Reducing carbon emissions in the built environment: A case study in 3D-printed homes” (published March 12, 2024), features a case study of 3D-printed homes employing CarbonX. The life cycle assessment results of the white paper show that the embodied and operational impacts of 3D-printed homes are lower than stick-framed construction.

Locally Sourced


CarbonX is a cementitious material made up of South Texas sourced materials that come together to produce an entirely new to market product. This unique material not only reduces carbon within the material itself, but by obtaining locally sourced materials, we also reduce our carbon footprint in procurement.

Strength in Numbers


CarbonX has achieved a 24% carbon reduction, quantifiable in 85 kgCO2e/CY, and boasts a compressive strength of 2,500 - 3,500 psi.

A Solution for the Future

By constructing all future ICON homes with CarbonX we will be able to reduce our overall environmental impact in building execution, while producing sustainable and energy-efficient homes to drive positive environmental impact now and into the future.

ICON’s CarbonX can be printed at high speeds while retaining form, enabling homes to be built faster while keeping construction projects on schedule and on budget.
