Sustainable Solid Waste Management Strategies for Higher Education Institutions: Diponegoro University, Indonesia Case Study

Abstract

Effective solid waste management strategies are recognized as efforts to achieve campus sustainability. The university campus is currently considered the center of various activities involving students, lecturers, staff, and other parties contributing to the consumption pattern of energy, water, and other resources. This study aims to estimate the quantity and compositions of waste generated on the Universitas Diponegoro (UNDIP) campus, identify the causes of waste generation, evaluate the relationships between variables through statistical analysis, and recommend possible strategies to reduce solid waste generation. The results show that the simultaneous contribution of the student-gender ratio, student awareness level, administrative staff background, and green space amounted to 67.7% of the waste generation at UNDIP. Therefore, these four factors need to be a concern for campus authorities in their efforts to handle campus waste. Student awareness in particular was determined to be the only factor that significantly affects solid waste generation. UNDIP may implement proper environmental education through sustainability courses in each faculty to reduce solid waste in higher education institutions since it has the most significant impact. Outcomes of this study could be used as a reference to develop sustainable campus strategies, recycling plans, and comprehensive waste management in higher education.

Waste Management Strategy as an Effort to Reduce Emissions Due to Open Waste Burning: Demak Regency Case Study

“…The data used to calculate the percentage of waste burned using the 2006 IPCC Guideline default number of 0.6 included the annual number of residents, waste management distribution by burning, waste production, and percentage of waste burned. Equations can be used to determine the carbon emissions produced by open waste burning [28][29][30]. The amount of open waste burned was calculated by multiplying the total population of Demak City by the fraction of the population that carried out open burning and the fraction of waste burned by the amount of waste processed [28].…”

Design of a Solid Waste Separation, Valuation and Recycling Centre on a University Campus. Case Study

“…University campuses are important generators of municipal solid waste [16]. The different activities of the population (e.g., students, teachers, administrators) in these institutions contribute to the increase in resource consumption patterns and, in turn, the effect that their waste generates on the environment directly or indirectly [17]. According to Budihardjo et al [17], these educational institutions must manage solid waste environmentally friendly, achieving institutional sustainability [18].…”

According to Budihardjo et al [17], these educational institutions must manage solid waste environmentally friendly, achieving institutional sustainability [18]. There are some cases of higher education institutions that developed waste management plans [19][20][21], and many of them contemplated that it is essential to generate environmental awareness in students [22].…”

Hazardous Solid Waste Management in Universitas Diponegoro: Planning Towards Environmental Sustainability

“…All wastes are still mixed. There is a center solid waste processing facility in Tembalang Campus to separate all waste before being sent to landfill (Budihardjo et al, 2021a).…”
