Here in most every little super market you trade used plastic and glass
bottles for quite a decent amount of money between 15 euro cent and 50
euro cent ($0.23-$0.80) per bottle depending on size so it adds up to
quite a lot, it is a very good way to get people to recycle. You put the
bottles in the machine, it scans them and then gives you a money
receipt you take to the cashier for euros.
