New Low-Carbon Concrete Outperforms Today's Highway Material While Cutting Costs in Minnesota
Concrete and its most important ingredient, cement, is one of the most carbon-intensive industries on Earth because it's used so often in construction. It has virtually no parallels for the ease of use, versatility, and structural properties, but emits about 0.6 tons of carbon per 1 ton of cement mixture produced according to Imperial College London.
US firm Carbon Upcycling Technologies, in collaboration with the Minnesota Department of Transportation (MnDOT) has successfully completed a three-year study on the use of the company's low-carbon cement in highways.
The results highlight Carbon Upcycling's ability to be a drop-in solution for reducing carbon-intensive cement in concrete, while saving money and making stronger roads.
The work in the study was carried out by Sutter Engineering and sponsored by the National Road Research Alliance (NRRA). It rigorously tested 16 unique concrete mixtures in real-world conditions on an active Minnesota highway to identify options that could reduce the carbon footprint of infrastructure without sacrificing strength or durability.
Completed in early 2024, the study aimed to find materials that could significantly lower the carbon footprint of concrete paving without compromising durability. Carbon Upcycling's CO2-enhanced mix achieved a 12.5% reduction in cement content while matching the workability of traditional concrete, allowing seamless handling, placement, and setting times for construction crews.
"Infrastructure is the very foundation of a sustainable future, and at Carbon Upcycling we're committed to creating materials that support this vision while establishing a secure, stable North American supply chain," said Apoorv Sinha, CEO of Carbon Upcycling.
"Our collaboration with the Minnesota Department of Transportation highlights how Carbon Upcycling can transform captured emissions into local materials that strengthen our infrastructure. By focusing on resilience and sustainability, we're contributing to a vision where our essential structures are clean and built to last."
