Gelber Sack is a "yellow bag" for recycling many kinds of packaging (the details are printed in the bag). They are distributed at Bürgeramt (see above). The bags are collected every other week (on Thursdays in downtown). There are no separate trash bins for Gelber Sack. Instead, they are collected in neat heaps outdoors, a day or two before they are picked up. Keep your eyes open in your neighborhood to find the locations.
