Gestão de resíduos da construção e demolição: um estudo de caso em Nova Esperança – PR

Abstract

The growth of cities and the intense urbanization process imply the need for civil works for housing, services and improvements in urban infrastructure. These activities have led to an increase in the generation of construction and demolition waste – RCD, which can cause damage to the environment and public health when discarded incorrectly. This study aimed to perform a diagnosis of the management and management of RCD in the municipality of Nova Esperança-PR. For this, in-place visits were carried out in the landfill area and the city hall of the municipality for observations, data collection and analysis of documents. In addition, questionnaires were applied to five municipal construction companies in order to evaluate the performance of the RCD management adopted by each one, which was classified according to the bad, regular, good, very good and excellent final grade. One contractor had a good performance with a grade of 9, one was rated very good and a grade of 8, while three constructors performed very well, two with a grade of 6 and one with a grade of 5. It was also checked whether there is a reuse of the RCDs in the works or if these are sent to recycling plants and it has been found that there is no RCD recycling in Nova Esperança-PR, and the waste is little reused. In addition, the study aimed to quantify the monthly RCD generation in the municipality and it was verified that the generation is approximately 150 tons monthly, however, the calculation of the total value was not possible due to irregular provisions in vacant lots, indicating the need for laws and oversight in the region.
