Gerenciamento e tratamento de resíduos químicos nas aulas experimentais de química: práticas e estratégias de sustentabilidade

Abstract

The increase in discussions on environmental issues, especially since the 1970s, has highlighted the need to rethink production and consumption models, with direct repercussions on educational institutions. As training and research centers, universities play a fundamental role in promoting sustainable practices, including the proper management of chemical waste generated in laboratories. The main aim of this study, carried out in the field of Chemistry, is to analyze and propose effective strategies for the sustainable handling of chemical waste generated in academic laboratories at the State University of Maranhão. The methodology adopted in the study included both qualitative and quantitative approaches involving awareness-raising actions with students from the different courses through banners and classroom talks, the application of a form to assess students' knowledge of the subject and processes for managing, characterizing, treating and disposing of the waste collected. The results revealed that although there are practices for segregating, storing and managing waste, there is still a certain level of ignorance among students about these procedures. The characterization of the waste showed significant variations in pH and concentration of dissolved solids, requiring specific treatment methods. The study reinforces the importance of integrating environmental management into the university's strategic planning, proposing the improvement of actions aimed at environmental awareness and education. These measures aim not only to comply with current legislation, but also to consolidate an institutional culture committed to sustainability and safety in laboratories
