This section (video) introduces the answer to the question of why food waste is a problem in the first place. The video also includes a case study in which a detailed characterisation of food waste was carried out. In this characterisation, more than 15 different food groups were distinguished. The result shows interesting results on food waste behaviour. The video ends with an estimate of the monetary losses per capita and year caused by food waste.This section (video) introduces the answer to the question of why food waste is a problem in the first place.
