Consumer food waste at the household level results from a complex set of behaviors depending on the local food environment, among other factors. This study mainly aimed at comparing food waste behaviors in the Cilento BioDistrict with those recorded at the national level to explore if the organic district model had an impact on food waste attitude as a sustainability element.

There is a need to find new and sustainable nutrient sources for organic farming. Urban (food) waste can be a highly valuable source with low environmental impact and high recycling efficiency. This source can be used to compensate for the negative nutrient balances in organic farming. However, it must be treated to become hygienic, biologically stable, and easy to handle. Solution Anaerobic digestion of food and organic waste in a closed system produces fertiliser (digestates) and energy while avoiding greenhouse gas (GHG) emission.
