Actualización de las guias de laboratorio de la facultad de ingeniería ambiental de la Universidad santo tomás de Villavicencio aplicando conceptos de quimica verde y trabajo en la microescala.

Abstract

The work carried out comes from the Macro inter-institutional project "Study for the management of waste generated in the laboratories of the Faculty of Environmental Engineering of the Universidad Santo Tomás Villavicencio headquarters" carried out between the Faculty of Environmental Engineering of the Universidad Santo Tomás Villavicencio and the Universidad Tecnologica Federal do Paraná (Mosquera , Barbosa , Montañez , & Murcia , 2019). This document represents the second phase of the Macroproject and its objective is to establish management measures, focused on the establishment of proposals for improvement in the prioritized laboratory guides, based on the evaluation of the dangerousness of the reagents used in these, the performance of tests of validation for the improvement proposals in the prioritized laboratory guides and finally, the estimation of the generation of hazardous waste according to the prioritized laboratory guides through stoichiometric analysis The execution of the project standardized a limit of guides based on the work material completed in the first phase. The total number of analysis guides were ten, according to the hazard ranking, subdivided into two groups, based on the hazards and the hazard categories established in the Globally Harmonized System. Based on the prioritizations, those highly dangerous reagents or activities that affect health and the environment are synthesized, substituted or reduced. With the support of the third principle of green chemistry and from the validation test, it was possible to eliminate toxic and ecotoxic,reagents. As a result, the laboratory guides are updated, reducing about 24% of the 320 hazards that were originally in the unmodified guides.; the decrease in the use of reagents in liquid or solid state is between 50% and 80% when comparing the use of substances in the original guidelines with the proposed guidelines, it is 27%..
