THE CONSTRUCTION OF CONCEPTS ON THE MANAGEMENT AND TREATMENT OF CHEMICAL WASTE: A TRAINING EXPERIENCE OF CHEMISTRY STUDENTS

This work aims to analyze the contribution of a training action to the awareness and improvement of the knowledge of students of Chemistry and Chemical Engineering of Universidade Federal do Rio Grande do Sul (UFRGS) courses, regarding the processes of management and treatment of chemical wastes and wastewater generated in the experimental course. The research was performed with 66 students enrolled in the Experimental General Chemistry subject in the second semester of 2017. For that purpose, a two-hour lesson action training course was offered. As data collecting tools, an Initial Questionnaire was applied before the training stage and a Final Questionnaire was applied after the training stage. In order to do the analyses of the questionnaire answers, were elaborated also images about the frequency of the words by using NVivo 12(®) software. The data set indicates a scientific inculturation/alphabetization of concepts by students in terms of the main treatment types used to mitigate residues that are generated in teaching labs, as Coprocessing, Incineration and Sanitary Landfill. It can also be inferred that the activity offered to the students contributed to the formation of values necessary for the formation of professionals more aware of their performance in society.
