Palabras clave: caracterización, generación, muestreo, subproductos RESUMEN Los estudios de generación y cuantificación de subproductos de los residuos sólidos urbanos, proporcionan herramientas base para la toma de decisiones en los municipios y en las localidades de México. Este trabajo fue realizado en la cabecera municipal de Berriozábal, Chiapas. Como resultados se determinó que la generación per cápita de residuos sólidos urbanos es de 0.619 kg/hab/d, la fracción doméstica equivale a 0.456 kg/hab/d y la no doméstica a 0.160 kg/hab/d. Respecto a la composición, se encontró que la fracción orgánica sigue manteniendo porcentajes altos (54.88 %), seguido de otros subproductos como plásticos (11.70 %), además de papel y cartón (6.87 %). Poco más de 78 % podría ser considerado como susceptible de recuperación, por lo que podrían ser aprovechados de alguna manera para no enviarlos directamente a disposición final y con ello alargar la vida útil de los sitios de depósito de residuos.Key words: characterization, generation, sampling, subproducts ABSTRACTThe studies of generation and characterization of solid wastes provide basic tools for decision-making in municipalities and towns of Mexico. This study carried was out in the municipal seat of Berriozabal, Chiapas. It was determined that the per capita generation of municipal solid waste is 0.619 kg/hab/d, the per capita generation for domestic sources is 0.456 kg/hab/d, and 0.160 kg/hab/d for no domestic sources. Regarding the composition, the organic fraction continues to maintain high percentages (54.88 %), followed by other products such as plastics (11.70 %), plus paper and cardboard (6.87 %). Over 78 % of solid waste generated could be used in some way, so it would not be send directly to final disposal, thus extending the lifetime of the waste disposal sites.

Abstract:This document provides a comprehensive review of the municipal solid waste management in the municipality of Villaflores, Chiapas, specifically the municipal seat and nearby towns. The main waste management problems were identified. Derived from the study, it was found that currently 0.707 kg/per capita day of solid waste are generated, equivalent to 59 tons/day, which are handled with limited equipment and personnel, leading to difficulties, specifically as regards final disposal. It was found that, despite the limited number and inferior characteristics of the existing collection vehicles, waste collection is moderately efficient (78%). Final disposal shows serious deficiencies, such as ruptures of cell geotextile liners, clogging of rainwater drain channel, neglected leachate evaporation pond, among others. To improve solid waste management at municipal level, the Department of Public Services in conjunction with the legal areas of the municipal council, and other external factors, such as academia and civil society organizations, should promote awareness strategies and waste separation at the source.
