Graphyte’s Carbon Casting technology transforms agricultural and timber waste into durable, carbon-rich blocks for permanent and affordable CO₂ sequestration. Our innovative solution offers over 1,000 years of carbon permanence with low production costs, making it a practical and scalable choice for billions of tons of carbon removal.
Graphyte is solving the problem of ineffective and costly carbon removal by offering a solution that is permanent, affordable, and scalable.
R&D Focus
Graphyte’s research and development focuses on permanent carbon dioxide removal through biomass-based carbon storage. Operating in a niche segment of low-energy, engineered carbon removal, the company uses agricultural and timber waste to develop scalable, affordable, and durable CO₂ sequestration through its proprietary Carbon Casting technology.
Innovative Solution
Graphyte is solving the carbon removal challenge through its proprietary Carbon Casting technology. This process uses agricultural and timber waste—materials that would otherwise decompose or be burned—and transforms them into dense, carbon-rich blocks. The biomass is first dried to eliminate microbes and moisture, then compressed and sealed in an environmentally-safe, impermeable polymer barrier.
Solution Effectiveness
Graphyte’s Carbon Casting solution is highly effective, offering over 1,000 years of carbon permanence while maintaining levelized production costs below $100 per ton—far more affordable than most engineered removal methods. It uses minimal energy by relying on natural photosynthesis and low-energy drying and compression processes. The technology retains nearly all the carbon captured in biomass and is designed to scale rapidly, with the capacity to remove billions of tons of CO₂, making it one of the most practical and durable carbon removal solutions available today.
