Waste composition and engagement in management initiatives: A study at Chulalongkorn University across academic periods

Abstract

Waste management poses a critical challenge for universities, with far-reaching environmental and social consequences. This study highlights the significance of Chulalongkorn University’s Zero Waste initiative, which has driven substantial progress in sustainable waste management. Between 2017 and 2022, landfill waste was reduced by nearly half, dropping from 4959 tons to 2424 tons annually, whereas recycling rates increased from 33% to 55%. By employing a systematic methodology, including waste quartering and statistical analysis, this study provides a comprehensive evaluation of waste composition and engagement practices at storage areas across the campus during different academic periods. The findings emphasize the initiative’s success in promoting waste reduction and recycling awareness, contributing to measurable environmental benefits. Even amid the COVID-19 pandemic, the initiative demonstrated remarkable resilience, mitigating adverse impacts and maintaining progress toward sustainability. This study underscores the pivotal role of evidence-based strategies, continuous improvement, and active community engagement in addressing waste management challenges, offering valuable insights for advancing sustainability in higher education institutions.
