Implementation challenges of blockchain technology in closed-loop supply chain: A Waste Electrical and Electronic Equipment (WEEE) management perspective in developing countries

Abstract

ABSTRACT Closed-loop supply chain (CLSC) activities ensure flawless Waste Electrical and Electronic Equipment (WEEE) management by the usage of IoT and Blockchain technology (BCT) is proven as an effective and sustainable solution among developed countries. However, implementation challenges including data integrity, accessibility, and reluctance to change restrict the potential of these digital technologies in developing countries. Thus, to extend the existing literature, the study has relevance. Based on a systematic literature review, Best Worst Method (BWM) is used for determining the most critical BCT implementation barriers affecting WEEE. This study identifies the IoT-enabled BCT implementation issues in closed-loop WEEE management. This study examines the appropriate issues in the context of developing a legislative support system, ineffective database management, low understanding of cognitive technologies, and information security and privacy are the key concerns for BCT implementation in closed-loop supply chains. The model is an effort in the waste management domain for the transition of developing economies towards circularity.
