Climate friendly canteens in schools

Out-of-Home-catering is gaining in importance in children’s and youth’s nutrition: in 2009 more than 45.000 schools in Germany provided community catering. Until now however, questions concerning climate and energy efficiency play no role in school meals. At this point the project comes into play. It analyses the food use, the energy consumption, the available and used kitchen technology and all processes from purchase to waste disposal in 24 canteens in all-day elementary schools. Subsequently menus and processes are optimized to maximize CO2 and energy savings. Following a successful test phase, a qualification campaign for kitchen staff is planned.
