PurposeThe authors posit that one of the key enablers of the circular economy will be the digital transformation – in other words, “digitalization.” In this study, the authors examine and visualize the interaction of the circular economy and digitalization by using scientific publications. They explore possible synergies and future research avenues at this junction.Design/methodology/approachThe authors first apply bibliometrics to explore and visualize the relationships between the circular economy and digitalization in the academic literature. Following the clustering of topics, they define key emerging factors for each cluster. Based on this analysis, they suggest future research avenues.FindingsThe authors find that there are four main clusters at the junction of circular economy and digitalization, including (1) sharing economy, (2) additive manufacturing, (3) business models and (4) industrial ecology and remanufacturing. They then dig deeper into these topics to better understand what factors would shape the future of the clusters. They conclude that sharing economy perspective and additive manufacturing may be enhanced by regulation-based and behavioral change-based approaches. Circular business models should be developed to maintain circularity in industry. Finally, digital manufacturing should be implemented within the framework of industrial ecology and remanufacturing principles to increase efficiency, productivity and traceability in the circular economy.Originality/valueDigitalization offers significant potentials toward breakthrough sustainability by creating a circular economy. Hence, understanding the relationship between circular economy and digitalization is important to achieve sustainable development goals.

Purpose The COVID-19 pandemic has disrupted the supply chains, and this brought researchers and practitioners to think about more on circular supply chains (CSC). The CSC concept has been discussed in the literature more than a decade. This study aims to find out the theoretical roots of CSC by analyzing scholarly articles in literature. Design/methodology/approach This paper uses document cocitation analysis for reaching this aim. After retrieving data from Web of Science database, this paper explores data set by considering used references of these publications and clusters them based on their title terms and visualizes them by using cosine similarity index. Findings This paper concludes that CSC is mainly discussed along with sustainability, sustainable supply chains and green supply chains, where the focus is integrating circular economy principles to supply chain management (SCM). On the other hand, although resiliency is an essential characteristic of SCM, contribution of CSC to supply chain resilience is neglected in the literature. Research limitations/implications CSC will gain importance in near future to increase national/firm productivity, and findings of this paper will give researchers insights for furthering their studies. Social implications To avoid supply chain and market collapse caused by natural disruptions, supply chain resilience is of paramount importance. According to the findings of this paper, the authors believe that business resilience in COVID-19-restricted environment may have exit point by using circular perspective. Originality/value The importance of CSC has increased due to the disruptions caused by the COVID-19 pandemic. Therefore, this unique study was undertaken to investigate the evolution of this crucial topic with evidence from the literature through a cocitation analysis.
