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 an-aerobic digestion and composting plant in Southern Italy.

It results that the biomethane and compost potential through an-aerobic 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.

Abstract
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 an-aerobic digestion and composting plant in Southern Italy. The purpose is to investigate the ad-vantages and disadvantages of collecting organic waste in rural areas and recovering it into bio-methane, 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 po-tential in Southern Italy, considering the amount of organic waste produced in 14 rural communi-ties 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 commu-nity composting in rural areas. It results that the biomethane and compost potential through an-aerobic 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 provid-ing policy implications in light of the National Recovery and Resilience Plan (NRRP) and the Common Agricultural Policy (CAP).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
