This is a plan of deep geologic repository in Germany. Wait, in Germany? I've heard Germany is closing down its nuclear plants?!
But who said it's #nuclear? Millions of tons of highly toxic mercury and arsenic waste is being stored worldwide in geologic repositories for decades. That's the only thing you can do because unlike nuclear waste you can't recycle these metals.
@kravietz You actually could recycle the metals, sorta, its just super expensive and not really workable yet. At least thats my understanding.
Basically you can use high voltage plasmas at high heat to break down literally anything to its elemental components. the issue is you can only do it in small quantities at a time for a lot of energy input.
