CEMEX Ventures is expanding in the sustainable concrete space, having announced an investment in Canadian carbon utilisation and grinding technologies company Carbon Upcycling Technologies.

Announcing its investment on Thursday (21st April), CEMEX said the move will help scale its capability to reduce clinker, a stony residue from burnt coal or a furnace, from its cement production process.

To do this, Carbon Upcycling’s solution infuses carbon into a grinding process for industrial residues, such as fly ashes and slag, to produce a more reactive supplementary cementitious material.

Once produced, the materials can then be used to replace clinker in cement production. The blended cement and concretes resulting from this process can achieve carbon dioxide (CO2) reductions of up to 30%.

Gonzalo Galindo, Head of CEMEX Ventures, said, “Our investment in Carbon Upcycling allows us to leverage the utilisation 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 decarbonise the cement production process and achieve carbon neutrality by 2050. We continue expanding our green construction investment portfolio and looking for new technologies to create a more sustainable industry.”

CEMEX and Carbon Upcycling have worked together since 2020, when CNEC agreed to test and scale up the Carbon Upcycling’s technology in its R&D facilities and develop industrial-scale projects across cement and ready-mix operations.

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