CARACTERIZAÇÃO E COMPOSIÇÃO DOS RESÍDUOS SÓLIDOS DOMICILIARES RECOLHIDOS PELA COLETA PÚBLICA EM ITUMBIARA- GO

Abstract

This study consists of a technical and social diagnosis of household solid waste (HSW) management in the municipality of Itumbiara, Goiás, structured to evaluate local compliance with the guidelines of the National Solid Waste Policy. The central objective is to analyze the gravimetric composition of household waste in Itumbiara to provide a basis for more sustainable public management strategies. The methodology adopted was comprehensive, integrating the survey of historical weighing records, the application of social perception questionnaires with residents, and the execution of gravimetric characterization tests using the quartering method on representative samples from urban collection routes. The study addresses the waste cycle in its entirety, from citizen behavior regarding source segregation to the logistical challenges faced by the municipal administration. By cross-referencing data on organic matter, recyclables, and hazardous waste fractions with the community’s perspective, the research highlights the need for regional and educational management. It is concluded that organic waste is the predominant fraction in the municipality and that recyclable materials account for approximately 21.2% of the sample, indicating the viability of expanding selective collection and supporting waste picker cooperatives.
