Each household or apartment building is equipped with three bins: one for paper, one for organic food and garden wastes (the “bio-bin”), and one for non-recyclables (“rest-waste”). They also have a “yellow sack” for packaging, such as yogurt cups and tin cans. The bins are emptied and the sacks picked up regularly by the local waste management company. In Freiburg the bio-bin is emptied once a week, the others once every two weeks. Glass must be sorted by color and deposited in community bins. There are 350 of these in Freiburg. Hazardous wastes like batteries, paints, pesticides, etc. can be dropped off at temporary collection sites or at recycling yards. Freiburg has 26 rotating collection sites that each accept hazardous waste twice a year, plus three permanent recycling yards. In addition, Freiburg recycles over 1 million corks per year. These are processed into “Recykork,” an eco-friendly insulation material, by handicapped workers at the local Epilepsy Center. Mayor Salomon points out that Freiburgers recycle more than the state or national average.
