ABSTRACT

Electronic waste (e-waste) is the fastest-growing type of solid waste. According to the United Nations (UN), e-waste costs the global economy around $37 billion annually. Indeed, e-waste impedes UN Sustainable Development Goals (SDGs). Toward sustainable e-waste management, Industry 5.0 (I5.0) can offer a comprehensive solution by integrating the core principles of sustainability, resilience, and human-centricity into the technological advancements of Industry 4.0 (I4.0). However, no earlier study has systematically investigated the link between e-waste mitigation and I5.0. To bridge this crucial gap, an evaluation of e-waste Mitigation Strategies (MSs) grounded on I5.0 enablers is conducted in this research endeavor. Initially, ten e-waste MSs and fifteen I5.0 enablers are formulated, with a foundation on pertinent policies and existing literature. Then, an integrated scenario-based Best-Worst Method (scenario-based BWM) and Fuzzy Vlse Kriterijumsk Optimizacija Kompromisno Resenje (F-VIKOR) framework is proposed for decision-making. By harmonizing fuzzy and scenario-based methodologies, this novel framework proficiently navigates both epistemic uncertainties and randomness. The scenario-based BWM analyzes the I5.0 enablers to determine their respective weights, while the F-VIKOR method is deployed to assess the e-waste MSs through the lens of the I5.0 enablers' relative significance. A case study conducted in India applied the proposed approach, showing 'sustainability' and 'control emission' as paramount I5.0 dimension and enabler, respectively. Notably, the MS 'adoption of take-back practices at top management' emerges as a linchpin for fostering sustainable e-waste management practices. The research findings are elucidated through an economic lens and juxtaposed with existing studies, with sensitivity analysis reinforcing the credibility of the results. The implications of this study offer practical insights and policy considerations crucial for all key stakeholders within the e-waste management ecosystem.
