Advancing Sustainable Procurement in E‐Waste Recycling Through Grey Integrated Decision Analysis

ABSTRACT The rapid expansion of electronic waste (e‐waste) presents urgent challenges for sustainable supply chain management. Selecting suitable suppliers is critical not only for economic efficiency but also for advancing circular economy practices such as recycling, reuse, and safe disposal. This study aims to identify the most relevant criteria for circular supplier selection and to evaluate suppliers using the Grey Integrated Decision Analysis (GIDA) method. Data were collected from five experienced industry and academic experts through structured pairwise comparisons. Nine criteria including recyclability, reuse, remanufacturing, and reverse logistics were assessed. A case study of six e‐waste recycling suppliers was conducted, with expert inputs used to assess nine criteria, including recyclability, reuse, remanufacturing, and reverse logistics. The findings show that “products to be reused” and “remanufacturing capability” are the most influential criteria, while Supplier 3 emerged as the best‐performing option, closely aligned with circular economy principles. Compared with other decision‐making methods, GIDA proved effective in handling uncertainty and incorporating diverse expert opinions. The study concludes that GIDA provides a robust, transparent, and adaptable framework for circular supplier selection, offering both theoretical contributions to decision‐making literature and practical guidance for sustainable procurement in emerging economies.
