Análise de Gestão de Resíduos Sólidos Urbanos Aplicada a uma Área de Coleta Seletiva Piloto

Abstract

This study shows results concerning the evaluation of solid urban waste in a pilot selective collection zone in the central area of the municipality of Frederico Westphalen - RS, from samplings carried out from October to November 2017. The quantitative study was carried out based on the weighing of collection trucks before and after the waste is discharged for sorting in the Intermunicipal Consortium of Solid Waste Management. The qualitative analysis was performed according to the quarrying process based on the sampling plan of solid residues governed by NBR 10.007/04. The weighing was performed on different days, considering Wednesdays (day of organic material collection) and Saturdays (day of dry waste collection), completing four weighing. The compilation of the waste characterization led to values of inorganic material of approximately 44.35 %, being these residues with high recyclable potential, and 55.65% of tailings. At weighing the amount of organic waste, an average value of 3,810 kg was quantified. In parallel to these analyses, a survey was made based on the distribution and quality of the 510 collectors in the selective collection zone. Due to the mentioned data, it is necessary the standardization of the collectors and a volumetric study of the residues produced in order to fully satisfy the demand on their disposal on public roads. In relation to the plan of sampling of the residues, the period of adaptation to the selective collection in the proposed area is still recent, considering that the residues arrive in a mixed way to the sorting unit, making it difficult the real application of the NBR 10.007/04. Concomitant to the next activities, the process of environmental education in the municipality must be continuous.
