Canadian cleantech firm CarbonCure is revolutionising construction with its CO₂-utilising concrete technology, significantly reducing emissions and advancing global efforts toward sustainable industry transformation.
CarbonCure Technologies, a pioneering Canadian cleantech firm, is making significant strides in industrial decarbonisation through its innovative carbon dioxide utilization technology for concrete production. At the forefront of this transformation is Kristal Kaye, who became CarbonCure’s Interim CEO in mid-2025 after serving as CFO since 2024. Known for her pragmatic leadership honed over three decades across diverse sectors including mining and energy, Kaye is directing the company with a focus on sustainable growth, operational excellence, and customer success.
CarbonCure’s technology introduces captured CO₂ directly into fresh concrete during mixing, where it permanently mineralizes by forming calcite nanoparticles. This process enhances the concrete’s compressive strength by about 10% within 28 days, enabling producers to safely reduce cement content, whose production is a major source of carbon emissions, by roughly 3%. Additional water treatment methods using CO₂ can further reduce cement needs, culminating in an overall cement reduction of up to 6%. These technological advances translate into a substantial carbon footprint reduction; for every cubic metre of CarbonCure concrete, approximately 17 kilograms of CO₂ emissions are prevented. A typical high-rise constructed with this material can therefore see a carbon saving near 680 tonnes.
The impact is already meaningful, with over 600 CarbonCure systems installed across 24 countries, each plant preventing more than 20 metric tons of CO₂ emissions daily, akin to removing a fleet of cars from the roads. The company’s approach has received strong validation, attracting backing from influential entities such as Amazon, global financial institutions, and academic powerhouses like MIT. Crucially, CarbonCure’s process is verified by carbon credit markets, allowing operators to realise both environmental and economic benefits.
CarbonCure’s clean technology is underpinned by rigorous scientific research and industry testing. Studies conducted at facilities like Ozinga’s concrete plants demonstrate that the integration of CO₂ mineralization improves performance without compromising durability, a frequent concern in sustainable construction. This gives confidence to engineers and project developers that CarbonCure-enabled concrete meets structural demands while significantly lowering embodied carbon.
Looking ahead, CarbonCure is actively pursuing policies and market mechanisms to accelerate its deployment in key regions including North America, Europe, and Asia. Efforts include advocating for regulatory reform and expanding direct carbon credit programs aligned with environmental goals. Kristal Kaye describes concrete as “quite literally part of the climate solution,” emphasising that innovations like CarbonCure can bridge the critical gap between industrial construction demands and global decarbonisation targets.
For professionals involved in industrial decarbonisation, CarbonCure exemplifies how captured CO₂ can be transformed from an environmental liability into a valuable resource. By embedding carbon mineralization technology into ready-mix concrete production, the firm is driving a circular economy model in one of the world’s most carbon-intensive sectors. As Kaye steers the company forward, the message is clear: integrating innovative CO₂ utilization at scale offers a practical pathway to reducing emissions within heavy industry, supporting broader climate goals while maintaining economic viability.

The process involves adding CO₂ as an admixture, leading to the formation of calcite nanoparticles that improve cement hydration efficiency. This technology allows for the optimization of concrete mix designs by safely reducing cement content without compromising quality or performance.
- https://www.osti.gov/servlets/purl/2483545 – A study examining the implementation of CarbonCure’s CO₂ utilization technology at Ozinga’s facilities. The research highlights two processes: 1) Concrete production, where CO₂ is injected during mixing to improve compressive strength and reduce cement content by approximately 3%, and 2) Water reclamation, where CO₂ is used to treat slurry water, saving up to 3% of cement. Combined, these technologies can save up to 6% of cement used in concrete production, resulting in reduced CO₂ emissions.
