Caracterização quali-quantitativa de resíduos sólidos em escolas públicas do município de Humaitá-AM

Abstract

This study aimed to perform a qualitative and quantitative characterization of the solid waste produced at the school Tarcila Meadow de Negreiros Mendes Integrated Time Educational Center (CETI) and School Governor Pliny Branches Rabbit (GM3) in the municipality of Humaitá, Amazonas state. The study was developed to understand the characteristics of waste generation in schools, as well as its composition and the relationship between the various types of materials that are discarded. The approach adopted was based on technical visits and the collection of samples on different days of the week, followed by the separation and weighing of waste according to its categories: organic material, paper, plastic (PET), metal, and others. The results indicated that the organic fraction accounts for the largest part of the total collected, representing more than 50% of the total mass, followed by recyclable waste such as paper and PET. This composition shows the consumption and disposal habits of the school community, highlighting the urgency of actions in environmental education and the implementation of selective collection practices. It is concluded that qualitative and quantitative analysis is essential to support the formulation of public policies aimed at integrated waste management, as well as to encourage sustainability in public educational institutions in Humaitá-AM.
