Waste electrical and electronic equipment (WEEE) has a great potential for contamination. The reverse logistics of WEEE
allows to identify and manage flows of equipment and parts that can be reused, exploited or destroyed. This article proposes the design of a logistics network for the transportation and exploitation of this types of waste in the department of Córdoba, Colombia. Additionally, a mixed integer linear programming model is proposed to integrate strategic-tactical decisions of the network such as the location of waste collection and transportation centers, maximizing gross profit. The results indicate that the mathematical model represents the proposed logistics network correctly. The model was validated and tested with various scenarios, reaching the optimum in all cases within reasonable times. Even in pessimistic scenarios, considerable profits were projected. This indicates untapped economic-environmental potential and opportunities for future research and development of business projects.
