Towards a greener future and innovating solid waste management in higher education institutions: A review

Higher education institutions (HEIs) are becoming key players in promoting sustainable practices within their communities, often by embracing the “green university” concept. This review explores how HEIs manage solid waste, using methods that aim to reduce waste at the source and promote recycling, resource recovery, and reuse. It focuses particularly on how environmental education influences students’ behaviors and raises awareness, helping foster a deeper commitment to sustainability on campuses. While many HEIs have made progress in implementing these strategies, various challenges remain, including limited resources, inadequate infrastructure, and gaps in campus-wide participation. This review provides a perspective by examining these practices within the unique context of HEIs and highlights the potential of integrated solid waste management (ISWM) to advance sustainability. Additionally, it identifies specific areas for improvement and emphasizes the important role of HEIs in shaping environmentally conscious individuals. Practical recommendations are offered to support HEIs in strengthening their waste management efforts, helping these institutions lead the way in environmental responsibility and instilling a culture of sustainability among students, faculty, and staff.
