In times when there is more and more focus on environmental impact, all aspects must be taken into account. Expanded polystyrene (EPS) is easy and cheap to produce and has lots of applications because of its properties. These properties however, also make it a hard material to recycle. This paper focuses on a rich mathematical model for the collection of waste EPS in order to improve the recyclability of the material. A real-world scenario is simulated and the result is a model for routing different types of vehicles which can also be used to make strategic decisions.
