Evaluación de la producción per cápita de los residuos sólidos en las unidades educativas de la ciudad de Riobamba.

Abstract

This research evaluated the per capita production (PCP) of solid waste produced in Educational Units of Riobamba city, which will be used as a tool to help Gobierno Autónomo Descentralizado Municipal de Riobamba, to take actions towards proper management integral in the management of solid waste in educational institutions due to the scarce information and current management by the Autonomous Governments. Fourteen representative educational institutions from the city were selected, the Analysis Methods and Solid Waste established by CEPIS / PAHO were applied to determine the PCP, heat capacity and specific density. Previously, the situational analysis of each of the educational institutions on the management of solid waste was carried out through surveys on environmental legislation. Therefore, obtaining as results that: the fiscomisional educational units accomplish 67,78%, the private educational units 47,22% and public educational units 32,22%. The PPC that educational units produce is 0.037 kg / student / day; and through the statistical analysis of Main Components, there were at least two components made up of: Plastic> Paper and cardboard> Organic waste> PET12 are the ones that contribute the most to PPC. To conclude, the heat capacity of the following analyzed residues were: glass obtained 0,76kcal / kg, wood 1,39 kcal / kg and PET12 3,2 kcal / kg. In order to obtain data for the possible use of energy, the heat capacity of usable organic waste would be 505,9 Watts / kg. For future research it would be opportune to develop the study with random samples of educational units and to carry out the sampling in different stages of the school year to validate the results.
