Propostas de melhorias no gerenciamento de resíduos em laboratórios do departamento acadêmico de química e biologia UTFPR - Curitiba

Abstract

The joint action of professors, students and trainees, in 2006, originated the Solid Waste Management Program of the UTFPR Câmpus Curitiba (PGRCC), in parallel, the Laboratory Waste Management Manual of the Academic Department of Chemistry and Biology (DAQBI) was elaborated. Currently, in the DAQBI’s laboratories, many experiments are performed using volumes of reagent in semimicro scale, thus reducing the amount of waste generated. But the PGRCC requires continuous financial and human investments, and there is a need to move on to the other stages that involve the reuse and recycling of materials. In this way, entering the PGRCC, the present work proposed improvements in Waste Management in Laboratories of the DAQBI of the UTFPR – Curitiba, based on the principles of Green Chemistry, the Hierarchy of Solid Waste Management, the waste inventory document analysis and in situ observations of the internal collection in August 2017. It was investigated treatments for residues containing silver and chromium ions, evaluating the viability of these treatments to become practical classes for the discipline of Industrial Solid Waste and the possibility of reusing the products obtained at the university itself. Finally, lectures were elaborated with guidelines for professors and students of the department, aiming at better waste management. Thus, according to the observations and data collected, changes and updates were proposed in the Laboratory Waste Management Manual. The research indicated that it is possible to recover these metal ions, however the treatments will only be feasible and useful if the waste segregation and labeling system are efficient. Thus, it is concluded that continuous monitoring is necessary in the system of segregation and identification of residues and the awareness of the academic community through lectures, since the results of these were positive, as can be observed in the internal collection of residues in May 2018, but periodic lectures as well as management reviews and updates are recommended.
