Waste disposal may work differently depending on where you live. You may discard your household waste only in so-called “Gebührensäcke” (specifically labeled rubbish bags). Supermarkets sell them in different sizes at the checkout. The garbage collectors come around on fixed days (leave the tied up rubbish bag by the roadside in the morning). Altnernatively, you can take the rubbish bag to a drop off point near you.
You can recycle PET bottles and batteries at the supermarket. Glass, aluminum, and tinplate can be discarded at drop off points in your municipality. Most municipalities regularly carry out collections for paper and cardboard or they provide fixed drop off points.
