Holcim US will collaborate with Blue Planet Systems and Lafarge Canada to scale technology that can sequester carbon emissions, helping provide circular economy benefits.
Holcim has invested in Blue Planet to support the development and commercialisation of its mineralisation technology.
Blue Planet’s novel process sequesters carbon emissions into aggregate that can make concrete carbon negative.
It can consume industrial waste, such as recycled concrete, cement kiln dust, and slag and produce new aggregate products, providing circular economy benefits.
Each tonne of Blue Planet’s aggregate can mineralise up to 440 kg of CO2, preventing it from emitting into the atmosphere.
“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,” Blue Planet chief executive Brent Constantz Ph.D., said.
“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.”
Holcim US, Lafarge Canada, and Blue Planet will work together to help identify potential to use of technology to further lower the carbon footprint of the companies’ cement, aggregates and concrete operations.
The companies will consider expanding the technology to other Holcim Group operations around the world.
“Being at the forefront of driving sustainable actions in our industry requires continuous innovation and partnerships,” Holcim region head, north America Toufic Tabbara said.
“Our investment offers a critical opportunity to influence the development of future technologies in the CCUS 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”.
