CEMEX, a Mexican multinational building materials company, announced that CEMEX Ventures, its corporate venture capital and open innovation unit, is investing in Carbon Upcycling Technologies, a Canadian startup and global leader in developing 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 slag and fly ashes, 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%.
