Abstract
Food loss and waste represents a global problem which is characteristic for all food supply chain sectors and all groups of countries. On average, every year one third of the total amount of food produced is lost or wasted, which indicates an extremely high level of inefficiency in the food supply chain. One of the key characteristics of food loss and waste is a wide range of ecological, economic and social implications, which is why this problem has become the subject of many national and global agendas. Although there is still no unique definition of the term food loss and waste and unique data collection methodology, many authors have researched this topic so far. Therefore, this paper's aim was to research the existing literature on the phenomenon of food loss and waste, as well as to observe trends of the amount of food loss and waste in the world and the EU. The results indicated that the differences between developed and developing countries have changed, and the amount of food waste in both groups of countries at the household level is now quite uniform. At the level of the EU, the household sector is also the largest generator of food waste.
