Toward food waste reduction at universities

Area of Science:

• Environmental Science
• Sustainability Studies
• Circular Economy

Background:

• Food waste (FW) poses a significant threat to global sustainable development goals (SDGs), impacting public health, social justice, and economic stability.
• Universities face substantial challenges with food waste, necessitating effective mitigation strategies aligned with circular economy principles.
• Despite growing awareness, a lack of targeted action and education on campus food waste persists, hindering behavioral change among students.

Purpose of the Study:

• To analyze and identify effective strategies for reducing food waste within university settings worldwide.
• To provide a comprehensive overview of the current state of food waste production and management in higher education institutions.
• To highlight the importance of integrating food waste reduction into university sustainability agendas and educational programs.

Main Methods:

• Qualitative methodology employing a comprehensive literature review.
• Analysis of case studies on food waste production and management in universities across selected global regions.
• Examination of factors influencing food waste and the efficacy of various prevention and reduction strategies.

Main Results:

• Significant variation in university food waste generation, ranging from 0.12 to 50 kg/capita/day.
• Identification of influencing factors such as demographics, seasonality, and consumer behavior.
• Demonstrated potential for food waste reduction (13-50%) through strategies like composting, trayless dining, and educational initiatives.
• Pinpointed four priority action areas: planning and awareness, food preparation and storage, service optimization, and direct waste reuse.

Conclusions:

• Implementing targeted actions in planning, preparation, services, and waste reuse can substantially decrease university food waste.
• Educational programs and awareness campaigns are vital for fostering sustainable eating habits among students.
• Adapting and deploying recommended strategies globally can enhance university sustainability and promote learning in environmental stewardship.
