Identification of optimal areas for the location of a sanitary landfill in the northern and eastern subregions of Valle del Cauca

This study seeks to identify optimal areas in the northern and eastern subregions of the Valle del Cauca where it is possible to locate a sanitary landfill, using a methodology that avoids as much as possible the impacts that this type of equipment causes to the environment. According to a study presented by the Superintendencia de Servicios Públicos Domiciliarios (2015), shows that the municipalities of the North and East Valley Subregions deposit approximately 173.24 tons of solid waste per day. For the amount of solid waste they generate and for not having a place where to deposit the waste in a controlled manner, the municipalities of the study area should look for options to carry out the final disposal in landfills outside the department or landfills that are located at considerable distances. In this order of ideas, it is necessary to identify the optimal location of a subregional landfill that meets the requirements of current regulations and that guarantees the least social, economic and environmental impact in the municipalities involved. The present study contributes to identify this location, based on the use of information technologies, literature review, principles of sustainable development and the use of detailed spatial information.  Este estudio busca identificar áreas óptimas en las subregiones Norte y Oriente del Valle del Cauca donde sea posible localizar un relleno sanitario, mediante una metodología que evite al máximo posible los impactos que este tipo de equipamientos ocasiona al medio. Según un estudio presentado por la Superintendencia de Servicios Públicos Domiciliarios (2015), muestra que los municipios de las Subregiones Norte y Oriente del Valle depositan aproximadamente 173,24 toneladas de residuos sólidos al día. Por la cantidad de residuos sólidos que generan y por no tener un lugar donde depositar los desechos de una forma controlada, los municipios del área de estudio deben buscar opciones para llevar a cabo la disposición final en rellenos fuera del departamento o rellenos que se localizan a distancias considerables. En este orden de ideas, se hace necesario identificar la localización óptima de un relleno subregional que cumpla con los requerimientos de la normatividad actual y que garantice el menor impacto social, económico y ambiental en los municipios involucrados. El presente estudio contribuye a identificar dicha localización, apoyándose en el uso de las tecnologías de información, la revisión de literatura, los principios del desarrollo sostenible y el uso de información espacial detallada.This study seeks to identify optimal areas in the northern and eastern subregions of the Valle del Cauca where it is possible to locate a sanitary landfill, using a methodology that avoids as much as possible the impacts that this type of equipment causes to the environment.
