As of January 1, 2013, Zurich is starting a separate waste concept for organic waste. Finally!
Currently, you can get rid of garden waste in separate containers, which you have to sign up for. As of 1/1/2013, the containers can also be used for organic kitchen waste. If you already have a "Gartenabfall" container, you do not have to do anything. Otherwise, you have to sign up.
More info and the form for signing up can be found here:
