What BoabD wrote about the Army way in Germany is law over here. We civilians are compelled to separate our garbage into different coloured bins for degradable, paper, not degradable and recyclable (plastic and tin cans). Bottles are brought to collecting points with containers spread all over the town. In the summer and fall every month garden refusals (grass, branches) are collected by special trucks and brought to the county recycling plant.
Bringing your own mug to a restaurant isn't necessary; you always get a reusable glasss or porcelain mug. Only hikers (like this man) use own mugs on their way when using clean springs or boiling their coffee or tea on the way.
At a street vendor's you drink out of the bottle or can. Only here salad is served on plastic dishes, with plastic cutlery which after use is collected in the yellow sack (recyclable garbage).
For shopping food we use cloth bags instead of plastic bags which are sneered as "Turkish valises". When I'm going to the market I always I have one or two cloth bags with me. The greenery is then packed in recyclable paper (not good to mingle cherries with onions).
It needs a time to grow accustomed to this system, but it works fine.
