Gravimetric Characterization of the Selective Collection of Bauru (Sp) in the Waste Sorting Cooperative – Coopeco

Abstract

The objective of this study was to perform the gravimetric characterization of dry recyclables from the selective collection in the city of Bauru, state of São Paulo as well as their residues and other qualitative aspects. The study site was in the Cooperativa Ecologicamente Correta de Materiais Recicláveis de Bauru (Ecologically Correct Cooperative of Recyclable Materials) - COOPECO. For the analysis and qualitative characterization, the method of homogenization and quartering of the samples was used, in which the dry residues of the selective collection were sampled in four days of the week. The percentages of dry recyclables obtained in the sum of the four days of the selective collection were: paper/cardboard (30.28%); glass (26.34%); plastic (19.62%) followed by residue (19.19%). The percentages of the residues from the conveyor were: 20.82% plastic and 10.48% paper, as well as the presence of organic components (10%), referring to training and environmental education.
