Analyzing the Evolution of Research on Student Awareness of Solid Waste Management in Higher Education Institutions: A Bibliometric Perspective

Abstract

Improper solid waste management (SWM) has resulted in an environmental and epidemiological catastrophe, emphasizing the urgency of SWM due to escalating solid waste generation. Over the past few decades, there has been significant growth in publications studying the relationship between SWM and the environment. Higher education institutes (HEIs) also have a social responsibility to promote public understanding of SWM and to increase awareness among students about SWM. A bibliometric analysis was conducted to provide an overview of research on student awareness of SWM in HEIs over the past 35 years. Data on publication output are identified based on the Scopus database (from 1989 to 2024). A total of 634 articles on SWM awareness and practices among students in HEIs were identified. VOSviewer was used to map the current studies and visualize the current trends in this area. The analysis of keywords used in the publications highlights recurring terms such as “recycling”, “environmental awareness”, and “waste management”, indicating the primary research focus. The results show a significant increase in publications in this area over the last 35 years. China, the US, and the UK emerge as the countries with the highest number of publications with 115, 82, and 44 publications, respectively, where China alone contributed 18.14% of the total publications on the topic, with the Chinese Academy of Sciences and Tsinghua University being the leading institutions in this research field. The results also highlight the top researchers in the field of student awareness of SWM in HEIs. It identifies influential journals in this field, such as Sustainability (MDPI) and the Journal of Cleaner Production (Elsevier). Overall, this study provides valuable insights into the current state of research on student awareness of SWM in HEIs, identifying research hotspots. It serves as a valuable resource for academics and practitioners interested in this area. The findings of the study are intended to guide researchers planning to conduct further research on the issue.
