Abstract

E-waste represents a rapidly expanding category of solid waste, with mobile phones being particularly noteworthy contributors to the global waste stream. The substantial consumer demand for mobile phones, coupled with their relatively short lifespan, limited repair options, and the absence of efficient recycling methods, significantly contributes to the generation of e-waste. In order to address this pressing concern, a sustainable circular inventory model that promotes green industrial practices without compromising profitability is a need in this era. This paper aims to develop an integrated sustainable circular model for a mobile industry that incentivizes the end-of-life processing of used mobile phones. The model explores the idea of the retailer’s inspection to segregate defectives and the manufacturer’s remanufacturing and product recovery initiatives to identify e-waste as a valuable secondary source of raw materials. The ultimate objective of this study is to determine the optimal expected average integrated total profit of the system with optimal order quantity and shortage quantity. An algorithm is designed to get the local maximum of the expected average integrated total profit using Mathematica 9.0 software. The practicability of the suggested model in the mobile industry is verified numerically and theoretically. The effect of investment in emission reduction technology and waste minimization technology with a carbon cap policy is studied, and it is found that the industry benefits from investments in green technology and waste minimization technology by generating 7.076% more profit while lowering emissions by 48.6336% and waste by 97.9758%. The study concludes that the implementation of the reuse, recycle, and rework concept of circularity for the end-of-life processing and product recovery of discarded mobile phones enhances the supply chain profit without contributing to pollution, which is the ultimate goal of a sustainable economic model.
