Ep 4 | How Sustainable Is the Critical Mineral Supply Chain, and Can We Rethink Criticality?

In this episode of the Energy Transition Talk, we explore our relationship with critical minerals. First, Paulina chats with Lauren Bridges, who researches industrial scale computing at Harvard University, and Zane Cooper, who researches digital media infrastructure and rare earth mineral extraction at the University of Pennsylvania. Lauren and Zane have also formed a research collaboration on critical minerals and e-waste. They talk about what critical materials are and why they matter for the energy transition, the relationship between the energy transition and the digital transformation, reframing energy as a dynamic process and a relationship rather than a material that we need to produce, rethinking the infrastructure design in our society and shifting energy demand, the e-waste feedback loop, and more. Justine then speaks with Prachotan Bathi, a Master’s student in computer science at the USC Viterbi School of Engineering, who works for a cleantech startup that identifies sustainable lithium mining sites for the EV supply chain. They discuss the importance of lithium as a critical mineral for the energy transition, the environmental footprint of lithium mining and EVs compared to gas vehicles, the ways companies are working to make lithium mining more sustainable, and the biggest challenges and opportunities of lithium mining. 01:54 Interview with Lauren Bridges and Zane Cooper 52:06 Interview with Prachotan Bathi 1:11:00 Concluding Remarks Don’t forget to subscribe to our podcast so you can automatically get access to our new episodes – you can find us on Apple, Spotify, YouTube, or wherever you get your podcasts.
