The transition to a circular supply chain (CSC) is a prerequisite to establish sustainability in the supply chain. Blockchain-based CSC enables stakeholders to effectively manage their decision-making processes increase revenue reduce time and costs and ensure information synchronisation. Blockchain start-ups play an essential role in facilitating the transition from a linear to a circular economy while supporting the development of CSCs. This research aims to explore the role of blockchain entrepreneurship in the transition to CSC by evaluating circular blockchain start-ups. This research contributes to the literature by providing verified roles of blockchain entrepreneurship in the transition to CSC by evaluating the literature and blockchain start-ups. Another contribution is that the causal relationships between these roles are analysed. In this study an integrated three-step methodology including Systematic Literature Review (SLR) Qualitative Comparative Analysis (QCA) and Fuzzy Decision-Making Trial and Evaluation Laboratory (Fuzzy-DEMATEL) methods on the base of the theory of change is proposed. An SLR is performed to determine the roles of blockchain entrepreneurship. Then a QCA is conducted after identifying the roles for verification by evaluations of use cases of blockchain start-ups. Finally the causal relationships between these roles are interpreted by using Fuzzy-DEMATEL. Findings indicate that blockchain entrepreneurship has 12 fundamental roles in facilitating the transition from a linear to a circular economy while supporting the development of CSCs. © 2024 Elsevier B.V.

Critical success factors for implementing blockchain-based circular supply chain

The growing importance of the circular economy has emphasised optimal utilisation of resources within the constraints of economic development and protection of the environment. Digital technologies associated with Industry 4.0 such as blockchain facilitate the implementation of circular economy principles throughout the supply chain. However because blockchain implementation in the supply chain is still in the early stages real-world examples of the blockchain-based circular supply chains (CSCs) are limited. The principal purpose of the paper is to examine the critical success factors (CSFs) for implementing blockchain-based CSCs. Following that 10 CSFs are identified through a short systematic literature review and then the integrated fuzzy cognitive mapping and fuzzy best-worst method (FCM-FBWM) is implemented to examine CSFs for the blockchain-based CSC. The study's main findings demonstrate that network collaboration is the best CSF while the shared circular economy toolbox is counted worst of all. This research enriches the literature by identifying the CSFs for implementing blockchain-enabled CSCs to address the lack of a suitable decision-making framework that assists managers in comprehending how blockchain technology can be adopted in the circular economy context. Implications for theory and practice are also discussed offering new insights into the measures necessary to ensure successful blockchain implementations in CSCs.
