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 the

environmental impact caused by the reverse logistics of car tires. System

dynamics is used to explain the behavior of the emissions generated

by four processes, the production of new tires, retreading, mechanical

crushing and co-processing, the last three refer to processes where you

can use the tires once these become waste. The environmental impact

of reverse logistics network allows the analysis of different environmental

variables that characterize the system, among which are the

carbon dioxide emissions, oil consumption and water consumption.

Different scenarios are also analyzed to evaluate the sensitivity of the

proposed model and identify the disposal that generate more and less

contamination, as well as to recognize the production process that

reduces emissions.
