Is There a Circular Economy?

In the next few years, there is going to be so much demand for battery materials that there's just not enough in a system right now to recycle. So I think with advances we're seeing and recycling, a circular economy is possible, but definitely not in the next decade. Right. That's substitution of different materials, maybe finding more benign and less damaging materials to use, like iron for instance. You can get anywhere.
