Why are minerals, one of the classic elements of nature so key to human existence, missing from the SDGs? Today Julia Keenan, Degol Hailu and I publish an article in @naturesustainab (free access: rdcu.be/cXglF) that attempts to answer this question.
Wrap your head around this: Storing the energy equivalent of one barrel of oil, which weighs 300 pounds and costs $81.00 requires 20,000 pounds of EV batteries that cost $200,000. Now imagine how much mining we have to do in order make 20,000 pounds of battery. #GreenEnergy
Another dodgy take. All these metals were mined before green energy and continue to be mined for other things, and they nowhere near add up to 98% of mined metals #factcheck
Some people seem to think it's just rare earth minerals that are needed to make #GreenEnery You also need copper, iron, aluminium, zinc, lead and nickel, and together that accounts for 98% of all mined metals.
Yeah, nah. This is a dodgy take. Most cobalt is produced as a by-product of copper mining & cobalt is the only one of the metals you have listed that has any significant artisanal mining as part of the supply chain. #factcheck
Most of mining's waste (>90%) is actually benign crushed rock, the problem is that after processing toxic metals and acids are left mixed in with the benign waste. It could be separated and used as a construction material when markets are nearby, but only a few companies do this.
I've worked nearly 30 years on mining & sustainability. Yes, metal demand for renewables will present huge challenges. But what this thread is not telling you is that there are many solutions to reduce mining waste, what's lacking is any real interest in implementing them.

I've been reflecting on divergent critical mineral definitions for a while now...Global collective discussions on mineral scarcity issues are necessary with the projected 2040 demands. For these discussions, there must be unified understanding and definition of what is critical.

(1/4) I am very pleased to share the second journal publication of my #PhD thesis!
