Holcim invests in firm that makes concrete carbon negative

Holcim North America, comprising Lafarge Canada and Holcim US, announced today it is financially backing Blue Planet Systems Corporation to support the development and commercialisation of their mineralisation technology.

Blue Planet’s technology sequesters carbon emissions into aggregate that can make concrete carbon negative.

Each tonne of Blue Planet’s aggregate can mineralise up to 440 kg of CO2 that would otherwise be emitted into the atmosphere.

The mineralisation process can consume industrial waste, such as recycled concrete, cement kiln dust (CKD), and slag and produce new aggregate products.

Toufic Tabbara, region head at Holcim North America, said: “Being at the forefront of driving sustainable actions in our industry requires continuous innovation and partnerships.

“Our investment offers a critical opportunity to influence the development of future technologies in the carbon capture space while at the same time, we grow our network of like-minded companies with the same strong focus on net zero to amplify global efforts along with other Blue Planet’s investors.”

David Redfern, president & CEO, Lafarge Canada, added: “This is an important step for us in North America. Our vision is to transform our St. Constant Plant in Montreal (QC) into a carbon campus that ultimately advances commercialisation of mineralization technologies including Blue Planet’s products.”

Holcim North America and Blue Planet will initiate a multi-year strategic collaboration to help identify the potential of mineralisation technology to further lower the carbon footprint of the companies’ cement, aggregates and concrete operations – with plans to expand to other operations in the Holcim Group.

Brent R. Constantz, PhD, CEO at Blue Planet, commented: “By focusing on the aggregate component of concrete, our technology can have a more impactful influence on the embodied carbon in concrete than the traditional focus on reducing cement component alone.

“Collaborating with Holcim enables us to apply our CO2 mineralization technology to large-scale cement operations where we expect it will more squarely address CO2 emissions.”
