That’s one of the best ideas I’ve heard in a while.

You sort of have to lay the can sideways on a belt and it spins it around before scanning the barcode, then it carries it to the appropriate bin internally (where it gets crushed). In my opinion it’s a waste of time, the machines are sticky and smelly and I feel sorry for the staff who have to go and un-jam them regularly, but on the upside you won’t see any littering around the place (well, in summer you will - it’s socially acceptable just to toss them on the ground but someone will be along to pick it up within minutes)
