Consumers’ perception plays a central role in tackling food waste at the final consumption stage, specifically among university students. In Europe, it is estimated that 47 to 67 Mt of food waste is generated at the household level or at food service consumption, including university canteens. The present cross-country research, through an online-based questionnaire among university students, investigates students’ perception on food waste by distinguishing among two different categories: on the one side, students living with their family; on the other side, students living without their family. Further, the research distinguishes among students eating at university canteens, students preparing food at home, students purchasing take-away foods and students coming back home to eat. The study compares university students’ perception on food waste in Italy and in Poland, with the overarching purpose of shaping sustainable pathways and defining educational interventions to enhance students’ perception and awareness on food waste. Data are analyzed according to the Mann–Whitney U test and the Kruskal–Wallis test. Age is a pivotal factor and suggests a generational gap in awareness and attitude toward food waste, whereas sex significantly affects food waste perception in Poland but not in Italy, suggesting a more homogeneous perception across sexes. The research highlights the impacts that socio-economic and environmental crises (e.g., climate change, the Russia–Ukraine conflict, high inflation rates) have on food waste perception in Poland, which is closer to that of Russia and Ukraine compared to that of Italy, and provides academics, practitioners and public authorities with practical and theoretical insights toward food waste minimization.

The sharp increase in rural tourism brings, on the one side, economic and social benefits among rural communities but, on the other, contributes to environmental challenges, specifically waste generation and natural resource consumption. From the ecological perspective, several pathways have been developed from local and global communities, such as prevention, reuse, recycling and energy recovery. The present research, by considering the need to boost separate collection and valorize organic waste among rural communities, evaluates the performance of a combined anaerobic digestion and composting plant in Southern Italy. The purpose is to investigate the advantages and disadvantages of collecting organic waste in rural areas and recovering it into biomethane, digestate and compost. First, the research develops the material flow analysis of a real, accessible and available anaerobic digestion and composting plant in Southern Italy. Secondly, on the basis of the results obtained, the research calculates the biomethane, digestate and compost potential in Southern Italy, considering the amount of organic waste produced in 14 rural communities identified as the most beautiful villages in Italy. Last, the research compares the advantages and disadvantages of producing biomethane through anaerobic digestion or resorting to community composting in rural areas. It results that the biomethane and compost potential through anaerobic digestion is 423,854 kg and 954,896 kg, respectively, but significant financial investments must be allocated in order to allow the municipalities to enhance the logistics and the separate collection facilities. The research highlights possible strategies under the circular economy lens to boost sustainability in rural areas, focusing on biomethane and compost production and providing policy implications in light of the National Recovery and Resilience Plan (NRRP) and the Common Agricultural Policy (CAP).
