Episode 14: Sustainable Mining & the Future of Copper

In this episode, we sit down with Andrea Vaccari from Freeport to explore the rising demand for copper and its crucial role in the clean energy transition. From electric vehicles to wind turbines, copper is everywhere—but how will we meet skyrocketing demand sustainably? We discuss challenges in mining, the shift toward responsible sourcing, and why designing for disassembly is key to a circular economy. Whether you're in product design, manufacturing, or just curious about the future of sustainable materials, this episode is packed with insights you won’t want to miss!

Shelley: One of the things I think is interesting and I think would be great to have you introduce to the listeners is the role of copper in the clean energy transition, because I don't think everyone appreciates how much metal is going to be needed to make that work. And it's also great context for those listening who might use copper or metal in their products. [00:44]

Andrea: That's right. Copper and molybdenum especially are really, really critical for the energy transition. When you think about all of our low carbon or zero carbon forms of energy. So we think about solar, when we think about wind, when we think about hydrothermal, even just thinking about LNG and how LNG actually provides power to a grid, copper's in all of that. In wind turbines, offshore wind turbines need lots of copper. I think actually a few tons of copper per wind turbine to be able to not only power the wind turbine, but then the deep sea cables that connect them and that connect them back to the grid. We think about solar power and it’s not just a solar cell; there are batteries involved. And how do you tie a battery storage device to infrastructure and to the Internet? That's copper. [01:02]

The simplest things, like developing nations, as they come along in the energy transition in a just way and we improve their grids, those are full of copper. Transformers, cabling in houses, as we improve green buildings, it's just everywhere. It really is. And then molybdenum is used in stainless steel and it's used in a number of other applications, but stainless steel especially and we know how much that's used in building and construction, bridges, all kinds of different applications for the energy transition. [02:07]

Shelley: Is it possible to give us any numbers for that, like forecasting 5, 10, 30 years, like how much is needed? [02:36]

Andrea: Right now the total refined copper market annually is in between 25 to 30 million tons a year and we expect that to double by 2050. Now you hear all kinds of different things. So, you hear people talk about doubling, tripling, quadrupling. I don't know, the way that I look at it is whatever number we come up with, we're always going to have the wrong number. But I think there's general consensus that it is at least twice. Just take like an electric car. So, if you take an internal combustion engine vehicle and then you take a fully battery electric car like a Tesla or a Mercedes, you're talking about three to four times the amount of copper per vehicle. And then you've got charging stations which are full of copper. [02:44]

Neil:. Some of these models don't even consider the development that you see in countries which are not electrified yet. So, India for the largest part isn't really electrified and in the next 10 years we will see a huge part of that also taking shape. So, I think you're right. Some of the numbers that I have in my mind, more short term where we'll be needin...
