Episode Description from the Publisher

On this episode of Future in Bloom, Steph Speirs speaks with Etosha Cave, co-founder and Chief Science Advisor at Twelve. Twelve is discovering new ways to recycle CO2 and transform it into the things we use in our everyday lives. Etosha discusses her journey from grad school, realizing nature doesn’t treat CO2 as waste, so why should we? She dives deep into the story of how she helped build a company that mimics photosynthesis to turn captured carbon and water into fuels and everyday products. Along the way, they discuss why CO₂ is such a “stubborn molecule,” how Twelve chose what to make from sixteen possible options, the role the Inflation Reduction Act played in their pivot to sustainable aviation fuel (SAF), and why the company can now produce jet fuel almost anywhere in the world. It’s a conversation about science, commercialization, and the belief that waste and pollution are design choices we can make differently.
