Adhering to the Ruhezeit (quiet time) in Germany also requires knowing when you can dump your glass bottles for recycling.
In Oberursel, the times are Monday – Saturday from 8:00 – 13:00 and again from 15:00 – 19:00. The time in between is the so-called Ruhezeit, when you can’t play any musical instruments, and do any drilling or other noisy home improvements (paid repairmen are excluded from this rule). You should also avoid doing noisy housework.
Yes, this is a quiet country.
The Federal Office for Environment suggests not using the Altglassammelbehälter (recycling glass container) after 20:00. Our area, the Rosengärtchen is a residential area, and I can only assume that because of this, the dropping-off is limited to 19:00.
