Quantificação de resíduos recicláveis na drenagem urbana do Lago Igapó I em Londrina - PR

Abstract

The inadequate disposal of solid waste in developing countries is a matter of concern, since the inadequate disposal in vacant lots, places close to water courses impede the flow of the urban drainage system and cause pollution of water resources. Thus, the quantification and typification of these solids is extremely important to find ways to solve the dumping of solid waste in Lake Igapó I, carried through the urban drainage network. The main objective of this work is to evaluate the amount of solid waste carried by the urban drainage system in the hydrographic basin. The quantification was carried out by weighing the material in the 50 L garbage bag together with a digital scale, giving the results of recyclable waste in kg and then calculating and leaving the percentage of the amount found in the measured weight. It can be observed that there is the presence of plastic types 1, 2 and PET that are classified according to NBR 10.004 as inert waste. These in turn represent around 70% of the total mass and 90% of the total number of items. These are residues that can be recycled, a lot of organic matter is also remarkable, but this was in a dispersed form, mainly as branches and foliage, in a complex way to be quantified.
