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.

The concept of sustainable development is becoming incomprehensible and complex in global supply networks, especially in low- and middle-income countries (LMIC) that are most affected by ever-changing industry challenges and standards. Smart technologies emerged by Industry 4.0, sustainability, and circular economy (CE) connection, which remain unexplored, can be integrated into the supply chain as a business strategy to increase collaboration and cooperation between different tiers of the supply chain to achieve sustainable development goals (SDGs) according to LMIC. Therefore, the main objective of this paper is to discover the drivers of a smart sustainable circular supply chain (SSCSC) in achieving the SDGs in LMIC through stakeholder theory. First, a systematic review is employed to identify the drivers of the SSCSC to achieve the SDGs in the LMIC incorporating existing literature on the subject. Second, the Best-Worst Method (BWM) is applied to analyze the identified drivers, and then the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used to analyze the SDGs. The applicability of the solution methodology was illustrated by providing a numerical example. The results of the study are twofold: firstly, drivers are analyzed by implementation of BWM. The results of the BWM reveal that economic sustainability is the best key driver among the eight drivers in achieving the SDGs, meaning that without financial assistance and support achieving the SDGs becomes ineffective. Secondly, the TOPSIS analysis reveals that SDG 16 (peace, justice, and strong institutions) is the SDG most supported by drivers.
