Germany collects glass, plastic & aluminium. Glass and plastic can be single use or multiuse. It’s kind of interesting how most beer is sold multi-use (every brand is using the same size bottles) to reduce the amount of recycling necessary. Beer bottles can be washed and reused rather than broken into cullet and remelted. I don’t know what France does but I could see people losing their minds if wine bottles were standardised the way beer is. But really glass could be collected and recycled even if it isn’t reusable.
