Holcim partners with Paebbl and Goldbeck on first industry application of carbon-storing technology
- Paebbl Rebond is a carbon-storing supplementary cementitious material (SCM) incorporating advanced CO2 mineralization technology
- Technology was used in innovative Holcim EPD-certified concrete to build foundations of a large-scale logistics center for a global retailer
- First commercial-scale application of Paebbl Rebond advances Holcim’s vision to be the leading partner for sustainable construction
Holcim has partnered with Swedish startup Paebbl and leading general contractor Goldbeck on the first commercial-scale application of a breakthrough carbon-storing technology in an innovative Holcim concrete, which was used to build the foundations of a logistics center for a global retail giant in South Germany.
Paebbl Rebond uses accelerated mineralization technology that actively turns captured CO2 into a stable, light grey mineral powder – composed primarily of magnesium carbonate and silicon dioxide – mimicking a natural process. This innovative supplementary cementitious material (SCM) can then be used to replace a portion of traditional cement, not only reducing embodied carbon in cement and concrete but permanently locking in CO2 .
Bengt Steinbrecher, Head of Holcim MAQER Ventures, through which Holcim has invested in Paebbl: “With this project we’ve proven how we can scale innovative technologies for a more sustainable built environment. It’s the result of a great collaboration with our partners, showing that construction innovation doesn't happen in a vacuum – but through a collaborative ecosystem.”
The innovative concrete floor slab mix enabled a 15% reduction in cement use versus the reference CEM II/B-M. In addition, it permanently sequestered 886kg of CO2 through mineralization across the 420m2 project area, demonstrating that innovative carbon-storing concrete can be used to realize large-scale building projects.
The project moved from concept to implementation in just six months, and involved laboratory testing in Holcim Innovation Center in Lyon, France, while plant trials with Holcim South Germany to assess concrete workability, air content and bleeding behavior were instrumental. Holcim also collaborated with Paebbl to produce a verified Environmental Product Declaration (EPD) for the concrete.
