Austria is kinda the same way. We had to sort everything into one of 6 bins. But there was only one bin for all plastics.

The 6 bins is fine (metal, glass, paper, organic, plastic, landfill), further sorting the plastics into the 7 kinds currently labeled might be a bit much (especially since only like 3 of them are commonly recycled).

I was curious about how they solved the mixed plastics problem, and quick searching around suggests most of the plastic gets incinerated.
