Este estudio tiene como propósito analizar el comportamiento de la generación de residuos sólidos domiciliarios por lados de manzana y por comunas, utilizando como ilustración datos de la ciudad de Cali, Colombia; se caracterizan estos lados de manzana y comunas con variables socioeconómicas de una muestra familias encuestadas, que determinan los perfiles de los generadores de residuos sólidos. Se hace uso del Análisis de Componentes Principales, como herramienta estadística multivariada para estudiar posibles asociaciones entre la composición socioeconómica de las familias y la generación de residuos sólidos. Los resultados obtenidos revelan altos grados de asociación entre niveles educativos y edades y mostraron que la generación y composición de residuos sólidos domiciliarios varían también según el estrato socioeconómico.
Abstract: This study aims to analyze the behavior of solid waste generation by block sides and communes, using as an illustration data coming from the city of Cali, Colombia. Block sides and communes are characterized based on socioeconomic measurements collected from a set of randomly sampled families, which helped us to build up the profiles of solid waste generators. We use Principal Component Analysis as a statistical multivariate tool to study possible associations between the socioeconomic composition of families and solid waste generation. Results show high levels of association among educational levels and age, and also that solid waste generation and composition vary from one economic stratum to another.
Sumário: A finalidade deste estudo é de analisar o comportamento da geração de resíduos sólidos domiciliares por lados de quarteirão e bairros, utilizando como ilustração dados da cidade de Cali, Colômbia; se caracteriza, estes lados de quarteirão e bairros com variáveis socioeconômicas duma amostra famílias encostadas, que determinam os perfis dos geradores de resíduos sólidos. Usamos o Análise de Componentes Principais como ferramenta estatística multivariada para estudar associações possíveis entre a composição socioeconômica das famílias e a geração de resíduos sólidos. Os resultados obtidos revelam altos níveis de associação entre níveis educativos e idades e mostraram que a geração e composição de resíduos sólidos domiciliares variam também de acordo ao nível socioeconômico.
