Plastic and sustainability: a bibliometric analysis using VOSviewer and CiteSpace
AI summary Read the abstract
Researchers conducted a bibliometric analysis of 1,933 research articles on plastic and sustainability published between 1995 and 2022. The study found that China and the USA lead global research in this field, with circular economy, bioplastics, and sustainable development emerging as highly discussed topics, and COVID-19 becoming a prominent theme in 2021 due to its impact on plastic pollution.
Purpose This study aims to present a comprehensive knowledge mapping and an in-depth analysis of plastic and sustainability research to understand better global trends and directions in this field that emerged between 1995 and 2022. Design/methodology/approach This study presents a visual analysis of 1933 research articles listed in the Web of Science (WoS) databases between the years 1995 and 2022 related to plastic and sustainability. The knowledge mapping based on CiteSpace and VOSviewer presents the current research status, which contains the analysis of the collaboration network, co-citation network, references with citation bursts and keyword analysis. Findings The results reveal that China and the USA are the most prominent countries in exploring the notion of sustainability and plastic. The Chinese Academy of Science is the most prominent institution. Chai Qiang, Friedrich Daniel, Sahajwalla Veena and Ok Yong Sik are the most prolific authors in this field. Furthermore, circular economy, bioplastic, sustainable development, polyester and bioplastics are the highly discussed issues in recent years. Not surprisingly, COVID-19 is the latest topic of discussion started in 2021 due to its negative impact on plastic pollution and the challenges it posed to sustainability. Originality/value This study is among the pioneers to shed light on the current research status of plastic and sustainability using the bibliometric method and the newest data. This study also suggests that collaborations between scholars and institutions require to be enhanced for better management of plastic pollution and to contribute to sustainable development.

AI summary Read the abstract
This bibliometric study maps ten years of global research on plastic waste recycling and circular economy using Scopus and Web of Science, identifying dominant themes, leading countries, and emerging directions. It is primarily a research-landscape analysis with minimal direct content on microplastic formation or health risks, making it only peripheral to microplastic science.
Plastic Waste Management: A Bibliometric Analysis (1992–2022)
AI summary Read the abstract
This bibliometric study mapped 30 years of scientific publications on plastic waste management (1992–2022), finding rapid growth in research output with China as the dominant contributor. Plastic waste management and microplastics emerged as the most influential research keywords, reflecting growing global concern about plastic pollution and water contamination. While this is a research landscape overview rather than an experimental study, it provides useful context for understanding how the field has evolved and where knowledge gaps remain.
