Gestión de los desechos sólidos existentes en la EPN (Bodega de la Metalmecánica San Bartolo).

Abstract

The Escuela Politécnica Nacional (EPN), located in Quito, Ecuador, has warehouses in which a variety of hazardous and non-hazardous solid wastes are stored. The warehouse that is the focus of this project is the one located at the San Bartolo Metalmechanics (MSB). The different types of waste stored there have not been properly managed and disposed of. The wastes that were found in the greatest quantity were the following: electrical and electronic components, scrap metal, and wood waste. This project seeks to provide possible proposals as a solution to the problem of the lack of management and abandonment of waste in the MSB warehouse. The solutions presented include recycling and reuse techniques for non-hazardous solid waste. To begin with, the waste was identified and then classified and weighed, for which a record was kept of the number of wastes found and their respective quantity. At the time of waste classification, those of greatest interest for this project were selected, which were: monitors, CPUs and scrap metal. The selection was carried out based on a qualitative (physical condition) and quantitative (weighing) characterization. After the characterization of the waste, the best techniques for recycling and reuse of the solid waste specified above were analyzed and identified. The 3 techniques found and selected for this project were: Extension of useful life, Reconditioning and Recycling of the 3 aforementioned wastes. As a result, a total of 38447.94 kg of waste was obtained, which was divided into 3411.2 kg of CPUs, 3960 kg of monitors and 31076.74 kg of metal scrap, destined for the 3 alternatives mentioned above. The largest amount of waste was scrap metal. The recycling and reuse proposals of the project can improve and encourage the management of waste stored in the different warehouses of the EPN; likewise, these alternatives will be of great help for the management of waste that will continue to be generated and accumulated in the future.
