The paper is part of the proceedings of an iPOPY seminar. The authors describe, how supply chains of organic school food might be organised in a sustainable way in order to serve high quality food to pupils. They present a best practice case of controlled food chains (filiera controllata) from Italy, the European champion of organic school food. From the province and the city of Piacenza in the region of Emilia-Romagna, we can learn a lot about a short and certified organic food-chain, a wide range of regional and organic products provided through a shared logistic organisation among local partners, and specific tender procedures
