Diagnostico de la gestión y el manejo de residuos líquidos químicos generados en las operaciones de docencia e investigación en los laboratorios de la Facultad de Ingeniería Química y Agroindustria de la Escuela Politécnica Nacional

Abstract

This research reviews a management`s diagnosis and chemical liquid waste management generated during teaching and research operations in four departments from Chemical and agroindustry Engineering schools at Escuela Politécnica Nacional. It has the purpose of establishing a baseline to contribute to the development of a sustainable campus model, through a descriptive study supported by quantitative and qualitative information obtained from primary sources and secondary as well as field data, documentary review, interviews and reported statistics 1192,4 liters of liquid chemical waste was identified and classified, the ones which were stored in 738 containers, with a weight approximately 1240,3 kg of which 45% are special waste and mostly complex mixtures derived from research and educational practices, 32% correspond to organic and inorganic aqueous dilutions. It was determined that the packaging is not suitable for containing such substances. No labels were evidenced with regulatory information and the designated spaces for storage do not have the necessary conditions of ventilation, luminosity, mobility and accessibility, described by the Ministerial agreement 061 and standard INEN 2266. The complexity level with these regulations in the FIQA does not exceed 10%, in terms of internal institutional regulation. Therefore, it´s considered non-existent, in consequence, it establishes guidelines for these fundamental parameters in the chemical waste handling and management.
