What if we could remove CO₂ from the atmosphere today—and keep it gone for 1,000 years? In this episode, I’m joined by Barclay Rogers, founder and CEO of Graphyte, who is pioneering a breakthrough method called Carbon Casting that uses biomass by-products and low-energy engineering to lock away carbon at a fraction of the typical cost. We explore why many emissions cannot be abated, how durable removals differ from nature-based fixes, and what it takes to make carbon removal bankable and scalable. Remarkably, Graphyte went from founding to full-scale operation in just 18 months—proving that durable carbon removal can be delivered today, not decades from now.
Listen in to discover how Graphyte is rewriting the carbon removal playbook—faster, cheaper, and at scale.
