Holcim & Eni explore new ‘green’ cement tech
Swiss-based building materials producer Holcim is partnering with Italian oil and gas company Eni to repurpose CO2 from its operations into green cement.
Eni is putting its carbon capture and mineralisation expertise to work to store CO2 into olivine, a widely available mineral. Researchers at Holcim’s Innovation Centre are exploring the use of this carbonated olivine as a new low emission raw material for the formulation of its green cement.

Holcim and Eni’s global operations, combined with olivine’s broad availability worldwide, would make this Carbon Capture, Utilisation and Storage (CCUS) solution highly scalable. It would enable the permanent sequestration of CO2 into building materials for greener construction, adding to Holcim’s broad range of innovative low emission raw materials. This partnership is in line with Holcim’s net-zero journey as well as Eni’s commitment to decarbonise its sector.
Edelio Bermejo, Head of Holcim’s Innovation Centre, said: “The world needs transformational technologies to accelerate our transition to net-zero. With the storage of CO2 in new minerals like olivine, we are expanding our range of green cement solutions, to make sustainable construction a reality around the world, while reducing the footprint of our operations.”
Holcim is currently mapping its most relevant sites in Europe to conduct industrial-scale pilots, to decarbonise its operations while expanding its green cement range. Its research team will focus on characterising the mechanical properties of carbonated olivine in concrete production as a new breakthrough raw material.
