摘要：This paper aims to present a review of household waste management in two small municipalities located at Mountain Region (RS – Brazil). As method, it was used data from waste amounts destined for regular and selective collection, physical characterization and gravimetric composition of the waste generated in three neighbourhoods of different social classes. It was observed that the largest municipality showed better efficiency and higher coverage of selective collection. The per capita index of waste generation was similar among municipalities, despite of differences in population size and in social and economic characteristics. The neighbourhoods with high and middle classes presented better segregation in both collections and municipalities. The presence of biodegradable materials in selective collection (average 14%) and recyclable materials in regular collection (average 21%) was observed. The obtained results indicated the necessity to continuously investing on expansion of selective collection and environmental education, in order to improve waste segregation, which contributes with the efficiency level of triage plants, as well as to increase the potential recovery of waste recyclable and the useful life of landfills.↓Este estudo apresenta uma análise do gerenciamento de resíduos sólidos domiciliares (RSD) realizado em dois pequenos municípios localizados na região da Serra Gaúcha (RS – Brasil). Em ambos os municípios foram utilizados dados obtidos de pesagem de resíduos destinados às coletas regular e seletiva e dados de caracterização física e composição gravimétrica dos RSD obtidos em três bairros com diferentes classes sociais. Foi observado que o maior município apresentou melhor eficiência e melhor cobertura da coleta seletiva. Os índices de geração per capita de RSD em cada município apresentaram valores similares, mesmo com as diferenças entre as características populacionais, sociais e econômicas. Os bairros de alta e média classe apresentaram melhor segregação em ambas as coletas e municípios. Foi observado ainda, a presença de materiais biodegradáveis na coleta seletiva (média de 14%) e materiais recicláveis na coleta regular (média de 21%). Os resultados obtidos demonstram a necessidade de investimentos contínuos na expansão da coleta seletiva e educação ambiental, tendo em vista a melhora da segregação de RSD, fato que contribui para o nível de eficiência de plantas de triagem de resíduos, bem como para o melhor aproveitamento do potencial de reciclabilidade de resíduos recicláveis e aumento da vida útil de aterro sanitários.
