For plastic bottles at least for the machine you would have to un-crush it, it scans the bottle.

For beer bottles, I dunno, try it out and report back?

It would be quite a long trip for me to try it.

How do you crush a beer bottle? They're always glass, no?

Or do you mean the beer can? In this case they can't be crushed, because the barcode has to be readable!

A friend tried hehe. If they're not too damaged you can put them back into shape, the machine is quite robust.
