Polyethylene terephthalate (PET) is a kind of solid waste generated that is 100% recyclable, however it is ending in landfills reducing the lifespan of them and consuming resources like petroleum in order to generate new products. Objective: Evaluating the effect on the environment of PET recycling by means of a system dinamics model.Material and method: The variables considered were water and energy consumption, CO2 emissions and landfill lifespan varying the PET recycling rate. RESULTS: the increase of the recycling rate cause a decrease in water and energy consumption as well as de CO2 emissions and produce a rise in the landfill lifespan. Conclusions: It is still important to follow the acomplishment of the solid waste management policies so as to enhace the decision making process related to generate a positive impact on the environment.esCorporación Universitaria LasallistaGestión de residuos sólidosDinámica de sistemasEnvases petResiduos sólidosReciclajeArticle
