A problemática do descarte irregular de resíduos da construção civil por pequenos geradores no município de Londrina/PR: caracterização de um ponto de descarte

Abstract

Currently solid urban waste (MSW) is a major environmental liability and ensuring the proper management of these is a challenge for the public administration. It is also necessary to take into account that a large part of MSW consists of construction waste (CW). Through a survey with the Municipal Transit Company of Urbanization of Londrina, a survey of points of irregular accumulation of CW by the municipality was carried out. For this work, a disposal area was chosen to be quantitatively and qualitatively characterized with respect to the residues deposited in them and to the community around them. The choice of area was due to the high volume of waste deposited in it and the aggravating factor of being considered a permanent preservation area. In order to fulfill the objectives of this work, a research questionnaire was applied with the objective of evaluating the residents' perception of the point of disposal regarding the problem of the same, besides a methodology of sampling and classification of waste according to ABNT 10.004 / 2004 and CONAMA Nº. 307/2002. After this evaluation it was noticed the heterogeneity of both the residues found and the community around the disposal point. 96% of residents claimed to know what recycling is, however, 46% did not know about the recycling capacity of CW. Among the main impacts perceived by residents were the daily burning of residues, as well as the smoke from it, besides strong odor and presence of animals. As far as wastes deposited in the area, 89% were classified as class II B - non-hazardous inert, 6% belong to class II A - non-hazardous non-inert, while 5% constitute class I - hazardous waste. Of the total waste sampled, 94% are considered as recyclable wastes, an index that points to the feasibility of implementing a more adequate management mechanism, in order to replace policies to prevent irregular waste by preventing them from happening.
