Abstract

We consider the problem faced by a recycling company that collects orange peel from both small producers and large orange juice companies. Pickup from small producers is limited by rural roads, where large trucks cannot traverse the streets. Hence, small vehicles are used to perform this task. An important feature is that small producers are willing to store orange peel residues until a large truck arrives to collect them, in exchange for economic incentives. Additionally, large trucks transport the consolidated orange peel from small producers and the residuals generated by large juice companies. The orange peel is then sent to a final customer, which, in this case, is a livestock farm, where it is mixed with grain feed.
From a mathematical optimization perspective, this problem can be seen as a variant of the well-known two-echelon location-routing problem (2E-LRP). The classical version of the 2E-LRP does not include the pickup and delivery assumptions considered in our problem. Specifically, in the first echelon, small vehicles collect orange peel from small producers and determine which of them will serve as collection points. In the second echelon, large vehicles transport the consolidated orange peel from the collection points and large juice companies to deliver it to the growth farms.
A mathematical formulation is proposed. A real-life scenario in the citrus region of Nuevo León, Mexico, is used to validate the applicability of the proposed study.
