How to reduce the impact of mining

from Volts · host David Roberts

In this episode, I chat with Johanna Wolfson, co-founder of Azolla Ventures, about their unique philanthropic-backed VC model tackling the tough problem of sustainable mining for the clean energy transition. We explore the promising tech Azolla is backing to reduce mining's impact, from using electrochemistry to refine copper without dirty smelting to advanced techniques for processing low-grade ores and even waste.
