Da mineração urbana à economia circular: estimativa do valor agregado aos metais advindos dos resíduos eletroeletrônicos gerados em Uberlândia- MG

Abstract

The consumption of electrical and electronic equipment is increasing and consequently the generation of WEEE as well. Given this scenario, this study aims to estimate the amount of e-waste that the municipality of Uberlândia-MG generated in 2021, estimate the amount of metals present and the value added to these metals. It was used to calculate the amount the model of KUSH and HILLS (2017), and for the amount of each metal and its values are analyzed from the data of the study by FORTI et.al (2020). The results obtained show that the municipality of Uberlândia generated 3,600,474.933 kg of e-waste and metals from this amount of mass would have the added value of approximately 20.6 million of Reais. The difficulty of reverse logistics not working, the lack of environmental education for the population, and the lack of incentive for the private recycling sector to ensure that these wastes are disposed of incorrectly, generating waste of natural resources, polluting the environment with their heavy metals and putting them at health risk waste pikers. Considering that Brazil sells at a lower price so that other countries can recycle it. Through this study, it is concluded that there is no effectiveness in the actions of those involved in alerting the population about wasting and risks to the environment, the public sector how much it needs more policies effective ensuring reverse logistics and the private sector as many opportunities for new ventures.
