Sustainability in electrical and electronic equipment closed-loop supply chains: A System Dynamics approach

In this paper we examine the impact of ecological motivation and technological innovations on the long-term behavior of a closed-loop supply chain with recycling activities. Ecological motivation manifests through legislation and green image factor, whereas technological innovations manifest through design for environment. We adopt System Dynamics methodology applied to many environmental systems seeking long-term gains. The developed model is implemented to a real-world supply chain of electrical equipment in Greece. Numerical analysis illustrates the factors concerned, like the delay of the legislation enforcement, to achieve a sustainable future through non-renewable resources and landfill preservation.
