What if the oldest miners on Earth weren't humans at all—but microbes that have been extracting metals for billions of years? In this episode, Karl and Erum sit down with Liz Dennett, founder and CEO of Endolith, who's deploying extremophile microbial communities to unlock up to 1.9x more copper from existing mine heaps at industrial mining sites across the US. Liz shares her journey from growing up in resource-rich Alaska to pioneering bio-leaching technology that's tackling a critical challenge: we need more copper between now and 2050 than humanity has produced in its entire history—and every data center, EV, and AI query depends on it. But here's what makes this conversation different: Liz isn't trying to disrupt mining, she's working with it, bringing "purple-haired PhD energy" to one of the world's most conservative industries through safety-first culture, collaboration over competition, and under-promising, over-delivering results. This episode reveals why biology might be our best tool for responsible resource stewardship and what it really takes to bring breakthrough biotechnology into legacy industrial systems—plus, the copper oxidation series on Liz's nails.Grow Everything brings the bioeconomy to life. Hosts Karl Schmieder and Erum Azeez Khan share stories and interview the leaders and influencers changing the world by growing everything. Biology is the oldest technology. And it can be engineered.
