Summary
Lucas and Luna explore how the cement industry, responsible for 8% of global CO2 emissions, is turning to an ancient Roman recipe to decarbonize. They break down how a startup called TerraCem is blending volcanic ash and lime to create a concrete that cures like Roman harbor structures, cutting emissions by 70% while matching modern strength specs. The episode dives into the economics: why this 'Roman concrete' costs slightly more than Portland cement today but could become cheaper with a carbon price of just $50 per ton. They also discuss the regulatory tailwind from California's Low-Carbon Concrete Code and why venture capital is suddenly pouring into the space. A concrete case of ancient technology meeting 21st-century climate policy. #RomanConcrete #CementDecarbonization #TerraCem #CarbonEmissions #GreenConstruction #LowCarbonConcrete #CaliforniaBuildingCode #VolcanicAsh #PortlandCement #CarbonPricing #VentureCapital #ClimateTech #Economics #FexingoBusiness #BusinessPodcast #Sustainability #Infrastructure #MaterialsScience Keep every episode free: buymeacoffee.com/fexingo
