The Environment Authority of Gothenburg Municipality developed an information campaign about environmental and financial consequences of food waste for the schools in the municipality. Teachers and students were encouraged to not take more food than they thought they could manage to eat and school kitchens were instructed on how to better plan the cooking. The schools participating reduced their food waste by just over 10 percent. Other schools competed in who could reduce food waste the most. Both school kitchen and school cafeteria waste was included. The result was 11 percent less food thrown into the bins. Others aimed to reduce salad waste, by only bringing out a little at a time to the buffet and refilling it often.
