INFLUENCE OF FLOATING POPULATION IN THE PLANNING OF THE URBAN CLEANING SYSTEM

Abstract

Adequate management begins with determining the characteristics of the waste generated “in loco” in order to carry out effective planning, since literature data may not correspond to local reality. Thus, this work aimed to determine the quantitative and qualitative characteristics of solid waste produced in the city Urutaí-GO, as well to study the effect of population seasonality and waste valuation. According to the results, during the IFGoiano Appropriate management begins with the determination of the characteristics of the generated waste “in loco” so that an effective planning can be carried out, since literature data may not correspond to the local reality. In this work, the objective was to determine the quantitative and qualitative characteristics of the solid waste produced in the city of Urutaí-GO, as well as to study the effect of population seasonality and the evaluation of these residues. According to the results, it was verifed that solid waste, during the Campus Urutaí IFGoiano school year, consists of 10.47% of plastics; 4.29% of metals; 4.13% of glasses; 13.17% papers and 61.11% discard material, with reductions of 34.99%; 55.35%; 39.39% 36.72% in the quantities of plastics, metals, glasses and paper, respectively, as well as an increase of 18.17% in the amount of discard material during the school holidays. The per capita generation, apparent specifc weight and volume generated monthly reduced from 0.75 kg hab-1 day-1, 17.60 kg m-3 and 144 m³, respectively, to 0.66 kg hab-1 day-1, 226,30 kg m-3 and 108 m³, respectively, during the school holidays. It was also verifed that the selective collection is a viable and self-sustaining alternative, being that its absence causes a waste of 3.4 minimum wages during the school year and of 1.6 minimum wages during the period of school vacations.
