A Network Flow Optimization Model for Automotive Glazing Recycling

In a recycling scheme such as the recycling of End of Life Vehicle (ELV) materials, the different stakeholders are expected to configure the operation process and the product distribution to maximize their own profits. However, these individual optimizations in many cases do not correspond to the maximal profit for the whole chain. In addition, the financial autonomy must be carefully studied beforehand and controlled so as to ensure an economically viable recycling chain. This paper proposes a cost-benefit parameterized model for the ELV glazing recycling scheme both for the network structure and the material flow sizing. The model is mapped onto real ground data from French industrial partners, and a linear optimization model is built to simulate the conditions of costs and benefits situations for the upcoming glazing recycling chain in 2015 in France.
