Designing the reverse network for WEEE in Denmark

In the challenging implementation of the European Directive on Waste of Electrical and Electronic Equipment (WEEE), the different fractions of waste at the individual collection stations must be assigned to the collective schemes which perform the waste treatment for the producers of the products. An approach is developed which provides an assignment which is efficient and fair for all the involved actors, e.g. the producers, the municipalities, and the collective schemes. We present an optimization-based decision support tool, which was developed for the coordinating government institution in Denmark, and numerical results for the current configuration.
