With globalization and the accelerated advancement of technologies, it is becoming increasingly easy to acquire electrical and electronic devices, resulting in obsolete products that are, consequently, discarded by their owners. The disposal of electrical and electronic waste has become an increasingly serious socio-environmental problem, since they contain heavy metals that are highly harmful to the environment and to human health. The research sought to investigate the reverse logistics of waste electrical and electronic equipment in the city of Teresina, Piauí, based on Law 12,305/2010. The research is exploratory, non-probabilistic, qualitative and quantitative. The necessary data were collected from January to July 2017, through a field survey, by means of the application of 60 closed questions, including seven objective questions, with the population, whose sample was chosen in a random manner, considering different neighborhoods of the municipality. Interviews were also carried out with companies that receive this type of waste and then with the companies specialized in the reverse logistics process of waste of electrical and electronic equipment (WEEE), one located in the city of São Paulo, SP and the other in the city of Recife, PE. The results showed that the population shows an interest in the environmentally appropriate disposal of this type of waste, but most of them continue to do so inadequately. The local companies carry out the proper collection and disposal, and then send the material to the company specialized in the manufacture of waste electrical and electronic equipment in Recife, PE. The city of Teresina advances in the management of WEEE; however, it still lacks the disclosure and participation of companies and public agencies so that the population may be becoming aware of and being responsible for the process of environmentally appropriate disposal of this type of waste.
