摘要

The increasing generation of waste electrical and electronic equipment (WEEE) is a global concern. In Brazil, the reverse logistics system established under the National Solid Waste Policy seeks to ensure environmentally sound WEEE disposal, but its effectiveness depends on consumer participation. This study examines the perceptions and disposal behavior of residents in a municipality in the interior of Brazil regarding WEEE. An online and in-person questionnaire was applied to a representative sample, and associations with socioeconomic factors were analyzed using Chi-square (χ²) tests and binomial logistic regression. Results showed that although 74.0% of respondents declared to know how to properly dispose of WEEE, only 39.4% used collection points, while 45.0% were unaware of their existence in the municipality. Significant associations were found between knowledge of WEEE and age (p = 0.016), family income (p < 0.001), and level of education (p < 0.001). Logistic regression analysis further confirmed that age and level of education were independent predictors of WEEE disposal behavior when controlling for socioeconomic factors. The results indicate that knowledge alone does not ensure appropriate disposal practices, highlighting the need for continuous investment in awareness campaigns, improved dissemination of collection points, and environmental education.
