| Abstract | This study aims to evaluate the environmental impact savings by different food waste management options of a university campus to support decision-making in the scope of sustainable campus. For this purpose, food waste generated inside the campus was characterized, and a hypothetical anaerobic digestion plant with a biogas recovery system was modeled. Two scenarios, representing the modeled plant, and current practices (landfilling and energy production methods) were formed, and life cycle assessment was conducted. For the modeled plant, the biogas and methane yields were calculated as 0.66 and 0.36 l/g VS, respectively, and generated electricity and heat were found as 92.6 and 188.9 kWh/day, respectively. Impact assessment results showed that global warming and acidification potential are the main impacts resulting from the current practices. More than 88% of impact savings can be achieved in all assessed impact categories by shifting to anaerobic digestion. In the scope of campus sustainability, 23% and 16% of the electricity and heat demand of the selected building on the campus can be supplied which results in 7%, 5%, 5%, and 4% impact reduction on campus level for global warming, photochemical ozone formation - impact on vegetation, terrestrial eutrophication, and acidification, respectively. Our results suggest that micro-scale changes may also provide a considerable amount of environmental impact savings. |
