There's usually two types of reverse-vending machines in a German store: One that takes refillable bottles from glass or hard plastics to be brought back to the bottler, which have been part of a deposit system for ages, and another one for disposable plastic bottles, for which a deposit system has been started about 15 years ago. Those disposable bottles are shredded on site and brought to a recycling plant. The first system makes ecological sense, the second one not so much (but it reduced litter for sure).
