Abstract

This article aims to design a strategic logistics design for household organic waste collection, processing, and compost distribution under a horizon plan. This involves the location of composting plants and their expansion over a long-term horizon, collecting organic waste for compost processing from clustered households (neighborhood associations), and distributing it back to households or communities. Within transportation decisions, we decide the number of trucks to purchase and trips for organic waste collection and compost distribution. Decisions about compost production include the plant location, their expansions over time, and the accumulation of organic waste within compost piles.

A mixed integer linear programming model is designed to minimize the total costs, including transportation, truck purchasing, plant location and expansions, and production costs. The results include a detailed logistics network design for the Quilpué commune, Chile. This design considers a 15-year horizon plan, a constantly increasing rate of household organic waste accumulation and collection, 84 clusters, and four sites for plant location. A sensitivity analysis is presented to evaluate the performance of the mathematical model. The results reveal the importance of having a structured plan for organic waste treatment and compost production.
