Cemex said Cemex Ventures, its corporate venture capital and open innovation unit, has invested in Carbon Upcycling Technologies, which has a solution that can reduce carbon emissions by 30 percent.
Carbon Upcycling’s patented solution introduces carbon into a milling process of industrial waste such as bottom ash and fly ash to produce a more reactive supplementary cementitious material.
These materials could be used as a substitute for clinker in cement production, so that the resulting added cements and concretes could achieve a CO2 reduction of up to 30 percent.
“Our investment in carbon upcycling allows us to leverage the use of CO2 in building materials and convert industrial waste into sustainable resources for building materials,” said Gonzalo Galindo, Director of Cemex Ventures.
He explained that this is another step in his roadmap to decarbonize the cement manufacturing process and achieve carbon neutrality by 2050.
“We continue to expand our investment portfolio in green construction and look for new technologies to create a more sustainable industry,” he added.
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 affecting the strength properties of the cement is a fundamental challenge for the industry’s decarbonization efforts in the near term.
This investment will facilitate the further development and viability of Carbon Upcycling’s technology and business model to reduce dependence on clinker in cement production.
The investment will also fund the rollout of its commercial carbon utilization solution at cement plants in North America, Europe and Asia, the cement company said.
