This study emphasizes circular supply chain management (CSCM) implementation model development for Micro, Small, and Medium enterprises (MSMEs) in the context of India by using the Extended Theory of Planned Behavior (ETPB) and Decision-Making Trial and Evaluation Laboratory (DEMATEL) method of decision making. This study identifies seven factors to develop ETPB with the help of experts and literature surveys. The DEMATEL method is used to analyze the prominence of factors, interrelationships, and causal relationships between the identified ETPB factors based on experts' opinions. The results indicate that there are three cause factors and the rest four are effect factors. ‘Social Pressure’, ‘Circular Incentives’, and ‘Pro-environmental Behavior and Responsibility’ are the significant causes. The Inbound Supply Chain is the prominent factor affected by all the six factors of ETPB. The research findings will be beneficial for academicians, policymakers, and practitioners as they provide insights into CSCM model development and help in recognizing significant measures to implement it.

This study examines the relationships between circular economy capability, green supply chain, green process innovation, and sustainable performance in the manufacturing sector of Saudi Arabia. As the country transitions toward its Vision 2030 goals, which emphasize sustainability and economic diversification, the manufacturing sector plays a critical role in adopting circular economy principles and green practices to reduce environmental impact and enhance resource efficiency. Using a cross-sectional research design, data were collected from managerial-level employees through a structured questionnaire. Data analysis was conducted using structural equation modeling (SEM) to examine the hypothesized relationships. The findings reveal that circular economy capability significantly drives green supply chain and green process innovation, which in turn enhance sustainable performance. The study also identifies green supply chain and green process innovation as critical mediators in the relationship between circular economy capability and sustainable performance. The results highlight the importance of integrating circular economy principles with green practices to achieve sustainability goals. It provides actionable insights for organizations to enhance their sustainability efforts, such as investing in resource efficiency, adopting green supply chain practices, and fostering process innovation.

The paper shows the results of an empirical study on the optimization of polymer waste supply chains based on the circular economy in Ukraine. The research shows that the main links in the activity should be harmonized for quality and quick optimization of polymer waste supply chains, including the processes of collecting, sorting, treatment, processing, and recycling of resources for maintaining the quality by total cost reduction. The research argues that the circular economy that stipulates the easy processing, recycling, disassembling, and restoring of products replaced the traditional linear model “take, produce, and throw out” that has dominated the economy by now. The study shows that the transformation of supply chains in production ecosystems forms competitive advantages at the enterprises that allow them to be more productive through efficient use of resources.

Waste management has evolved from a local sanitation issue to a global interdisciplinary challenge, integral to circular economies, public health, and climate change mitigation. This scientometric survey analyzes the intellectual landscape of highly cited waste management research. Using a dataset of two hundred highly cited documents retrieved from Scopus, this study employs performance analysis and science mapping techniques to examine publication trends, influential authors, core journals, and dominant research themes. The analysis reveals a significant concentration of influence among a limited number of authors and journals, with a marked increase in publications after 2015. The intellectual structure is anchored by several major themes: plastic and microplastic pollution, circular economy frameworks, biological treatment technologies (anaerobic digestion, composting), chemical and thermal conversion (pyrolysis, gasification), material-specific recycling (e-waste, construction and demolition waste, batteries, steel slags), and advanced wastewater and soil remediation. A notable focus on the environmental and health impacts of pollutants, particularly from plastics and pharmaceuticals, coexists with technological solutionism. The field is shifting from end-of-pipe solutions to upstream strategies like prevention and circular design. Future research must prioritize the social and economic dimensions of implementation, develop standardized methods for emerging contaminants like microplastics, and address the challenges exacerbated by crises like the COVID-19 pandemic.
