The industrial civilization and a global nature of economic events is characterized by irrational use of food and, as a result, its waste. On a global scale avoidable food waste has adverse impact on the environment and leads to economic losses. Locally it entails the necessity of managing growing quantities of waste and extra expenses related thereto. The purpose of this study is to identify consequences of waste in a food chain in the economic, social, energy and environmental security dimensions estimated based on data in reference literature and the authors’ own research. Research results show that waste reduces food security both nationally and locally, poses a significant hazard to the environment (by increased consumer waste), results in the irrational use of water, the waste of energy cumulated in discarded commodities and at the same is an important barrier to satisfying societies’ needs related to nutrition.
