Forecasting Waste Mobile Phone (WMP) Quantity and Evaluating the Potential Contribution to the Circular Economy: A Case Study of Turkey

Information and communication technology (ICT)-based products have a significant effect on increasing levels of waste electrical electronic equipment (WEEE) or (e-waste) due to their shorter lifespan as result rapid technological changes. Mobile phones are the most popular ICT products, market share is gradually. Therefore, effective management mobile (WMP) sought recovery brings enormous economic regulatory benefits. Forecasting quantities WMP recoverable material content generates valuable data for related stakeholders in circular economy (CE) design supply chain networks. This paper presents an approach determining quantity Turkey considering system from sales end-of-life (EOL) stages years between 2001 2035. The proposed model includes two main parts: estimation forecasting. Firstly, generated estimated based dynamic using Distribution Delay (DD) Method 2020. To select suitable future projection, seven different time series methods (e.g., Simple Exponential Smoothing, Holt’s, Logistics, Gompertz, Logarithmic, Bass, ARIMA models) considered estimate WMP. For given data, Holt’s determined be best method forecast 2021 In addition, materials amount revenue potentials expected approximately 11.5 million units has 52 US$ potential present study contributes literature, it first holistic forecasting quantification WMPs Turkey. Moreover, since include remarkable terms CE, findings this may help policymakers, governments, producers, consumers, all establish e-waste approaches.
