This talk presents an application in collaborative recycling efforts for non-profit agencies. The work is motivated by a project with a network of hunger relief agencies (e.g., food pantries, soup kitchens and shelters) focusing on collaborative approaches to address their cardboard recycling challenges collectively. The problem is modeled as a periodic location routing problem with operational choice. A metaheuristic is compared to the exact solution of the problem. The relative difficulty introduced with each decision is examined. Computational results on synthetic instances as well as a case study based on data from the network will be presented. In this novel setting, we evaluate collaboration in terms of participation levels and cost impact. These insights can be generalized to other networks of organizations that may consider pooling resources.
