Abstract In recent years, the concepts of circular economy and sustainable lifestyle have taken concrete form. The United Nations has outlined a set of targets, called Sustainable Development Goals (SDGs), through which the level of development of society can be more easily analysed. By following the 17 development directions, lifestyles can be improved, with an appropriate relationship with the rest of society. The current situation of food waste is reflected in at least five of the SDGs, to eradicate hunger, to improve climate actions by minimizing greenhouse gas emissions, to facilitate safe drinking water, for the conservation and sustainable use of oceans, seas, and marine resources, for restoring, and promoting sustainable use of terrestrial ecosystems and for responsible consumption on households and corporate level. The paper aims to highlight, incorrect practices and conventional and technologically innovative solutions to minimize food waste as much as possible, as these activities can reduce the carbon footprint and support existing models of a sustainable green economy. The results will highlight the critical intersection of circular economy principles, sustainable living, and the United Nations' Sustainable Development Goals (SDGs) in the context of food waste. By examining current practices and proposing both conventional and technologically innovative solutions, the study underscores actionable measures.
