A bibliometric review of barriers to circular economy implementation in solid waste management

Abstract

AbstractCircular economy (CE) has attracted considerable attention from governments, policymakers, and societies due to its potential to promote sustainable development goals while shifting away from linear economy models. Despite a growing body of research conducted in the CE, the barriers to its successful implementation for solid waste management (SWM) remain less explored especially in context of municipal solid wastes, and commercial and industrial wastes. The purpose of this current study is to identify the critical barriers to circular economy implementation in SWM. The scientometric analysis of literature is the research methodology in this study. A total of 1709 journal articles were searched and retrieved from Scopus database for the data analysis. The results show that circular economy has not gained much root in solid waste management in the global south. Countries such as China, United States, Australia, Italy, and United Kingdom (UK) are the topmost countries to fund research in this research area. The commonly used keywords in scholarly literature on this topic include sustainability, reuse, waste management and recycle. Further, the major findings of the study were grouped into clusters relating to challenges on macroeconomic policies, recycling and reuse of waste, stakeholder management, operation, and legal regulations, generated solid wastewater treatment, and construction and demolition waste. The contributions of this research are twofold: a comprehensive list of relevant gaps for further studies are provided for the scientific community to delve into this matter and proffer solutions. The findings could serve as a guide to understand and develop best practice framework on circular economy and its implementation in the SWM.
