Scientometric Analysis of Waste Management: Unveiling Global Trends, Patterns, and Impact - An Update of Last 50Years

Abstract

This study presents a comprehensive scientometric analysis of global research in waste management over the past five
decades (1974–2024). Using the Scopus database, 1,770 research and review articles were analyzed through
bibliometric techniques such as citation analysis, co-authorship mapping, keyword co-occurrence, and bibliographic
coupling with the support of VOSviewer and MS Excel. The analysis highlights significant growth in waste
management research, particularly after 2015, in response to global sustainability initiatives. Findings reveal that
the United States, India, and China are the top contributors, while key research themes center on medical waste,
plastic waste, hazardous waste, recycling, and the circular economy. Highly cited works and influential authors were
identified, along with collaboration patterns across 136 countries. Additionally, keyword analysis indicates emerging
areas such as COVID-19-related waste management. The study underscores the role of scientometric methods in
identifying research gaps, mapping global contributions, and guiding future investigations. By providing a structured
overview of trends and patterns, this work contributes to advancing effective waste management practices aligned
with sustainable development goals.
