This contribution addresses the optimal design and operation of a reverse supply chain of empty agrochemical containers. The problem is tackled by means of a multi-period MILP model, which relies on a superstructure that includes all the potential/existing collection centers and possible/existing plastic treatment plants, as well as the farms. Its decisions involve selecting the new facilities, their sizes, and installation periods, along with the operation of the facilities and the material flows among the various nodes in each planning period. A realistic case study has been solved under several scenarios in order to analyze the model scalability and to test its response to changing conditions.
