Thank you for the info.
Coincidentally, my daughter has a poster of that very castle hanging on her wall, it slipped my mind.
Oh, and in the US, we refer to Mülltrennung as Recycling, but it is only enforced in certain areas. Most places it either costs extra, in addition to standard garbage pickup fees, or you have to take it to recycling centers around the city. A lot of people are against it, believe it or not; I've actually heard enforced recycling referred to as "Communism."
Thanks again!
