Dynamic simulation model to evaluate the environmental impact of production and reverse logistics of tire

Abstract

This article presents a system dynamics model which evaluates theenvironmental impact caused by the reverse logistics of car tires. Systemdynamics is used to explain the behavior of the emissions generatedby four processes, the production of new tires, retreading, mechanicalcrushing and co-processing, the last three refer to processes where youcan use the tires once these become waste. The environmental impactof reverse logistics network allows the analysis of different environmentalvariables that characterize the system, among which are thecarbon dioxide emissions, oil consumption and water consumption.Different scenarios are also analyzed to evaluate the sensitivity of theproposed model and identify the disposal that generate more and lesscontamination, as well as to recognize the production process thatreduces emissions.
