Diseño de una celda diaria para la disposición final de los residuos sólidos del cantón General Antonio Elizalde –Bucay

Abstract

The objective of this work was to design a daily cell for the final disposal of solid waste in Canton Bucay, through the application of calculation memories, reflected in the plans that were executed in AutoCAD. Information was collected through interviews and surveys of the population, to find out the current situation of the integral management of solid waste, from the source to the final disposal in the current sanitary landfill of the canton. A consecutive sampling of seven days was carried out, to know the characterization and densities of the solid waste to be disposed of in the cell. Automated equations were formulated to quickly obtain projection results on the generation of solid waste, leachate, and stack gases, which will be controlled during the 25-year useful life of the cell. It was obtained that the per capita production of the population is 0.46 kg / inhab / day of which 64.45% is organic waste, and 34.55% of inorganic origin. The production of leachate is estimated to have a flow of 6487.771 m3/year and a generation of chimney gases of 30, 4084 ft3 / year in the first year of project execution. The daily cell will have a total area of 5.76 hectares, with a future solid waste generation of 1778.35 Tn / year, for which a total of 12.25 m3 / day will be necessary as daily coverage. It is concluded that based on the information obtained, the design of five plans was achieved that together guarantee the proper functioning of the daily cell for the final disposal of solid waste. It is recommended to carry out the technical closure of the current sanitary landfill based on current environmental regulations.
