How Zero-Carbon Minerals Transform Industries and Cut Emissions
CarbonFree, a leader in decarbonization technologies, has made a groundbreaking sustainable leap with the launch of endurocal™, the world’s first zero-carbon mineral. Designed to replace conventional calcium carbonate in diverse industries, endurocal™ is paving the way for a greener, more sustainable future.
This innovative product holds immense potential for reducing carbon footprints across various manufacturing processes, including plastics, paints, and paper. CarbonFree aims to revolutionize industries while significantly mitigating industrial emissions by introducing a zero-carbon alternative to a widely used chemical.
How endurocal™ Revolutionizes Industry
Endurocal™ offers a sustainable alternative to conventional calcium carbonate—one of the most commonly used specialty chemicals globally. It is designed for seamless integration into existing processes, serving industries reliant on calcium carbonate to enhance product quality and efficiency.
Currently, the domestic market for calcium carbonate is approximately 30 million metric tons, encompassing applications in architectural paints, plastics, paper, and beyond. With endurocal™, companies can now opt for a carbon-neutral option that maintains the same quality and functionality as its traditional counterparts.
The SkyCycle™ Technology Behind endurocal™
The innovative endurocal™ is made possible through CarbonFree’s proprietary SkyCycle™ technology. This process captures carbon dioxide (CO2) emissions directly from industrial facilities, preventing their release into the atmosphere. The captured CO2 is then converted into high-quality calcium carbonate, identical to the mineral found in natural limestone.
The true game-changer is that calcium carbonate produced via SkyCycle™ remains non-emissive. Regardless of how the mineral is used—whether in paint, plastics, or other applications—the CO2 remains securely stored within the product. For example, architectural paints commonly contain 30-40% calcium carbonate, and the CO2 embedded in the material stays locked away even after application.
Environmental Impact of endurocal™
The production of endurocal™ reduces emissions at the source and displaces the carbon-intensive processes used to create conventional calcium carbonate.
For perspective, CarbonFree’s partnership with U.S. Steel will deploy SkyCycle™ at its Gary Works Blast Furnaces starting in 2027. This project alone is expected to capture 50,000 tons of CO2 annually, equivalent to removing nearly 12,000 passenger cars from the road. The captured CO2 will then be transformed into endurocal™, preventing approximately 150,000 metric tons of emissions associated with traditional calcium carbonate production each year.
Additionally, the project incorporates calcium recovery from slag—a byproduct of steel production—further reducing waste and emissions in the steelmaking process.
Enhancing Sustainability Across Industries
The introduction of endurocal™ offers industries a dual advantage: reducing their carbon footprints while maintaining competitiveness. For example, manufacturers in the paint industry can use endurocal™ to create products with a significantly lower environmental impact, aligning with growing consumer demand for sustainability.
Plastic and paper manufacturers, too, benefit from adopting endurocal™, leveraging its zero-carbon properties to meet environmental regulations and improve their sustainability credentials.
Martin Keighley, CEO of CarbonFree, emphasized the importance of this innovation: “Endurocal™ represents a breakthrough in the recycled use of carbon dioxide, providing a cost-effective path for manufacturing competitiveness using emissions that would otherwise go to waste.”
Scaling Up: The Path Ahead
CarbonFree’s collaboration with U.S. Steel is just the beginning. The company is actively working to scale its SkyCycle™ technology and expand endurocal™ production to meet the growing demand for sustainable materials.
This approach addresses industrial emissions and demonstrates the potential for circular economies, where waste products like CO2 and slag are repurposed into valuable resources.
As global industries face increasing pressure to decarbonize, innovations like endurocal™ offer a clear pathway to achieving sustainability goals without compromising quality or performance.
A Vision for the Future
The launch of endurocal™ signifies a monumental step in the fight against climate change. CarbonFree exemplifies how technological innovation can drive meaningful environmental change by turning emissions into opportunities.
This breakthrough aligns with global trends toward carbon neutrality, reinforcing the need for scalable solutions that address industrial emissions. With endurocal™, industries have a practical and impactful tool to transition toward greener practices and contribute to a sustainable future.
How You Can Support Zero-Carbon Innovation
For businesses, adopting sustainable materials like endurocal™ is not just an ethical choice—it’s a competitive advantage. By integrating zero-carbon minerals into production, companies can meet regulatory requirements, reduce operational costs, and appeal to environmentally conscious consumers.
Policymakers, too, play a crucial role in incentivizing the adoption of such innovations. Investments in technologies like SkyCycle™ can drive widespread change, helping nations achieve climate targets.
As individuals, supporting brands and products that prioritize sustainability encourages industries to adopt greener practices, fostering a collective shift toward a low-carbon economy.
