  • CEMEX has invested in Carbon Upcycling Technologies, a solution that enables the reduction of carbon emissions in cement and concrete production by up to 30% through clinker substitutes.
  • The technology will help scale CEMEX’s capability to reduce clinker in its cement production process.

MONTERREY, MEXICO— CEMEX, S.A.B. de C.V. (“CEMEX”), announced today that CEMEX Ventures, its corporate venture capital and open innovation unit, is investing in Carbon Upcycling Technologies, a Canadian startup and global leader in the development of carbon utilization and grinding technologies for the cement industry.

Carbon Upcycling’s proprietary solution infuses carbon into a grinding process for industrial residues, such as fly ashes and slag, to produce a more reactive supplementary cementitious material. These materials can then be used to replace clinker in cement production. The blended cement and concretes resulting from this process can achieve CO2 reductions of up to 30%.

“Our investment in Carbon Upcycling allows us to leverage the utilization of CO2 in building materials and transform industrial residue into sustainable building material resources. Our investment in Carbon Upcycling is another step in our roadmap to decarbonize the cement production process and achieve carbon neutrality by 2050,” expressed Gonzalo Galindo, Head of CEMEX Ventures. “We continue expanding our green construction investment portfolio and looking for new technologies to create a more sustainable industry.”

The production of clinker, the main component of cement, is the most carbon-intensive part of the cement manufacturing process. The addition of clinker substitutes without compromising the strength attributes of cement is a critical challenge to the industry’s decarbonization effort in the short term.

This investment will facilitate the continued development and scaling of Carbon Upcycling´s technology and business roadmap to reduce reliance on clinker in cement production. The investment will also fund the rollout of its commercial carbon utilization solution across cement facilities in North America, Europe, and Asia.

CEMEX and Carbon Upcycling have worked together since 2020 as part of CEMEX’s Future in Action program. The companies agreed to test and scale up the startup’s technology in CEMEX’s R&D facilities and develop industrial-scale projects across cement and ready-mix operations.

“We are grateful for CEMEX’s continued support in our journey towards decarbonizing the cement industry,” said Apoorv Sinha, CEO of Carbon Upcycling. “We are well on our way to becoming the most impactful carbon utilization company of this decade, and we are thrilled to have CEMEX and other investors on board with us.”

The Future in Action program focuses on reducing the carbon footprint of CEMEX’s operations and products to become a net-zero CO2 company by 2050. Through CEMEX Ventures, the company is discovering and investing in companies that will provide proven, scalable technologies to achieve carbon neutrality.

About Carbon Upcycling Technologies

Carbon Upcycling was formed to use the waste of today to build the materials of tomorrow by converting CO2 gas into advanced material additives. Since 2014, Carbon Upcycling has scaled its ability to utilize CO2 emissions from point sources, such as power plants, by over 10 million times in reactor size. Carbon Upcycling’s carbon-enhanced additives primarily service the concrete industry but have complementary additives that are used in plastics manufacturing, coatings, and consumer products.
