What do you do with waste?
In Stuttgart there is a grey bin for residual waste, a green bin for paper and a brown bin for bio-waste. Plastic and packaging are placed in "yellow bags" that are available from the Citizens' Service Centre and some supermarkets.
Waste and yellow bags are picked up on specific days. Stuttgart municipality will provide you with a waste calendar informing you of the respective collection days in your residential district (unfortunately this is not available in English).
