Avaliação da gestão dos resíduos da construção civil e estimativa de geração no município de Campo Mourão-PR

Abstract

Civil construction is one of the most important segments of Brazilian industry and represents an indicator of economic and social growth, however, it is essential to have control of the processes involved, as there are several impacts generated from the extraction of natural resources to the stages execution of the works. The main impacts generated are due to the high amount of waste generated and represent great challenges to public management, as the control of proper management in all stages (segregation, packaging, collection, transport and final destination) needs to be constantly on the agenda in order to implement actions more effective management methods. Therefore, considering that the basic premise for defining solutions to the problems faced in the management of RCC is knowledge of the local reality, this study aimed to evaluate the management of construction waste in the municipality of Campo Mourão-PR, considering the existing management actions, companies operating in the management of RCC, areas of irregular disposal and estimated generation. It was identified that the municipality does not have effective public management actions and does not have specific legislation clarifying the responsibilities of small and large RCC generators. It was also verified that the companies do not have effective control over RCC collection, transportation and final disposal services provided in the municipality, which made data analysis difficult. Regarding the areas of irregular disposal, 82 points were verified, and in 22 places in fact waste was found irregularly discarded and the others represent possible places of irregular disposal. There was a generation of RCC in the municipality of 77,500.80 ton for the year 2019, with rates of 2.24 kg/inhabitant.day and 817 kg/inhabitant.year. The information obtained and analyzed in this study shows that the municipality of Campo Mourão lacks regulations for the correct management of the RCC, since the implementation of the PMGRCC, with the definition of responsibilities to large generators, through the PGRCC, and with the institution of a Municipal Program with efficient public policies, through incentives, environmental education, guidance and inspection, could change the scenario found.
