Experimenting on closing the metal flow loop in the global mobile phone product system: a system dynamics modeling approach
(English)Manuscript (preprint) (Other academic)
Waste electrical and electronic equipment (WEEE), well known as e-waste, is one of the fastest growing waste flows worldwide with increasing complexity in production through distribution to end of life (EoL). In this waste stream, a high number of mobile phones makes e-waste more compelling to examine the whole life of the specific product. In addition, having an interest in e-wastes for informal recycling in developing countries (DC), industrialized countries (IC) export e-wastes to developing countries. The emerging economies of reuse, refurbish and export of used mobile phones not only make the EoL complex, but also make the systems more challenging to sustainability. Since industrial ecology (IE) advocates resource efficiency with closed loop systems, we adapted a system dynamics modeling approach to investigate the dominance paths and driving forces for closing the metal flow loop through the concept of industrial symbiosis and eco-cycle modeling. This study finds higher efficiency for closing the loop in collection systems of used phones, mobile phone use time, and informal recycling in developing countries. By analyzing the dominant parameters, an eco-cycle model is proposed which could enhance a closed loop system by decreasing pressures on non-renewable resources. Improved policy supports accompanying consumer and corporate awareness with responsibility could create a circular consumption in the global mobile phone product system.
