This thesis conducts a comprehensive analysis of the dynamics of food waste and loss (FWL) along the international food value chain, highlighting their severe impacts on the environment, society, and economy. It makes a clear distinction between Food Waste (FW) and Food Loss (FL), proposing specific mitigation strategies for each category. The research indicates that annually, approximately 1.3 billion tonnes of food, which represents one-third of all food produced for human consumption, is discarded.
