I've toured our local MRF and was shocked at how good it was at robotic / magnetic separation. Incredibly fast AI trained 'pickers' pulling material off a belt (sorting by visually distinct plastic types, e.g. PET vs opaque plastics, paper, etc), combined with some human labor and magnetic extractors. Very high capture rates for all plastics except films - those remain hard to sort / grab. I was not expecting this level of performance...
