The construction industry is experiencing a massive shift towards sustainability, led by the latest patented invention from Solid Carbon, Inc. Recently issued under US Patent 12673895, the patent titled “Concrete mixture including solid carbon” outlines a groundbreaking formula that integrates solid carbon products directly into concrete mixes. This innovation allows builders to lock away carbon permanently without compromising structural integrity. You can learn more about the visionary team behind this breakthrough at their official website: https://solid-carbon.com/. By utilizing a solid carbon product with less than 75% carbon by weight and greater than 25% ash, the formulation successfully offsets the high carbon emissions traditionally associated with cement calcination.
What makes this invention truly innovative is its ability to seamlessly integrate into existing concrete batching systems while maintaining standard performance metrics. Historically, adding high amounts of biochar or biogenic carbon to concrete would degrade compressive and flexural strength. However, Solid Carbon’s new mixture meets rigorous ASTM standards, achieving at least 90% of the strength of control mixes. This allows for scalable, real-world application, turning the built environment into a massive carbon sink. It is a restorative solution that goes beyond merely doing less harm, actively lowering the Global Warming Potential of concrete construction projects.
Winner of Oregon’s Patent of the Month for August 2026
Because of its immense potential to combat climate change, this concrete mixture has been awarded the prestigious Patent of the Month for the state of Oregon for August 2026. Oregon has long been a hub for green technology and sustainable development. Solid Carbon, based in McMinnville, Oregon, perfectly embodies the state’s commitment to environmental stewardship. The award committee recognized the invention not just for its scientific merit, but for its immediate commercial viability. As the world searches for scalable ways to reduce industrial carbon footprints, this technology stands out as a prime example of how local Oregon businesses are providing global solutions to climate challenges.
R&D Tax Credit Eligibility in the USA
The practical applications of this patent present a significant opportunity for companies to claim the Research and Development (R&D) tax credit in the United States. To qualify for the R&D tax credit, a company must undertake activities that pass the four-part test established by the IRS: permitted purpose, technological in nature, elimination of uncertainty, and process of experimentation. When concrete manufacturers or construction firms develop new mix designs incorporating Solid Carbon’s additives to meet specific structural requirements or local environmental regulations, they are engaging in a process of experimentation. Testing the curing times, compressive strength, and workability of these novel carbon-negative mixtures relies on the hard sciences of chemistry and engineering to resolve technical uncertainties. By documenting these iterative testing phases and the resources spent on developing specialized concrete formulas for new applications, businesses can confidently claim these expenses as qualified research activities, thereby lowering their tax liability while investing in sustainable infrastructure.
