A Sustainable Step Forward: Lafarge Canada and CarbiCrete Partner to Scale Deployment of Carbon-Negative Concrete Technology

  • Lafarge partners with climate tech company CarbiCrete to tackle sustainability challenges in the construction sector with carbon-negative concrete blocks
  • Driving circular economy by using waste materials as a main component in concrete block production 

Montreal, QC, December 07, 2023 — Building on its commitment to accelerating green growth, Lafarge Canada, a leader in innovative and sustainable building materials, today announced a groundbreaking partnership with CarbiCrete, a climate tech company at the forefront of eco-friendly construction solutions. This collaboration emphasizes sustainability, innovation, and the transformation of waste into a valuable resource.

Lafarge's St. Constant - Montreal East manufacturing cluster is at the forefront of this initiative. The Lafarge team will process the material used in the CarbiCrete manufacturing process, a byproduct of the steel industry, which often goes to landfills but is now repurposed as a vital ingredient in CarbiCrete's carbon-negative concrete block technology.

"We are committed to reducing our environmental footprint and leading the way in sustainable construction.” expressed Andrew Stewart, vice president of Cement at Lafarge Canada (East). “Our partnership with CarbiCrete is a testament to our dedication to offering sustainable solutions and actively participating in the circular economy."

Our partnership with CarbiCrete enables the development of a new product for customers like Patio Drummond, utilizing technology to produce concrete blocks free of traditional cement to showcase this collaboration's real-world application and impact on building projects across the Province of Quebec.

“Collaborating with Lafarge allows us to leverage long-established infrastructure and years of expertise in processing steel-related byproducts,” says CarbiCrete CEO Chris Stern. “This enables us to make an immediate climate impact as we scale the deployment of our technology which reduces embodied carbon in concrete by both avoiding emissions and removing carbon through mineralization.” 

With a shared commitment to sustainability and innovative construction solutions, Lafarge and CarbiCrete are set to shape the construction industry. We aim to minimize the built environment's environmental footprint and contribute to creating a more sustainable world.
