How a Humble Rock Could Transform Industry

Concrete is everywhere—from our homes and bridges to skyscrapers and data centers. But few people realize that the cement used to make concrete is responsible for roughly 8% of global carbon emissions. If cement were a country, it would be the third largest emitter on Earth. And yet, these materials haven't changed much since the Roman Empire. Why has innovation been challenging in the concrete and cement space? And why are entrepreneurs, investors, and policymakers now suddenly paying attention? On Political Climate, hosts Julia Pyper, Brandon Hurlbut, and ClearPath's Rafae Ghani sit down with Brimstone CEO Cody Finke to explore one of the most ambitious industrial innovations in decades—what the startup calls a "Rock Refinery." Rather than simply making cement cleaner, Brimstone is rethinking the entire production process, creating a model that could lower emissions while also producing critical materials that are essential for economic competitiveness. In this episode: Why cement has become one of climate's biggest—and least understood—challenges How Brimstone is reinventing a manufacturing process that has changed little in centuries Why heavy industry could become a major source of American economic growth What it takes to commercialize breakthrough industrial technologies How innovation—not just regulation—could reshape the future of manufacturing and decarbonization If you've never thought much about cement, this episode might change your mind. Political Climate is presented by ClearPath, one of the most influential organizations working to advance American energy innovation while reducing global emissions.
