Gerenciamento dos resíduos de construção e demolição: estudo de caso no município de Pitanga - PR

Abstract

With the growth of the civil construction sector in recent years, the generation of construction and demolition waste increased significantly and caused economic, social and environmental impacts. Given this reality, many countries have implanted guidelines and standards, aiming to regulate the handling and final disposal of this residues. In Brazil, CONAMA Resolution nº 307, established in 2002, and the National Solid Waste Policy, of 2010, are the main legal references on the subject, however, most of the Brazilian cities, mainly the small ones, have not yet elaborated their Construction and Demolition Waste Management Plan, nor have they consolidated good practices in order to manage their waste in a proper and efficient way. Thus, this research aimed to support the development of a Construction and Demolition Waste Management Plan in the city of Pitanga-PR, based on economic, technical, legal, environmental, administrative and educational aspects, including the quantitative characterization and offering alternatives for the city to implement CDW management actions, considering the local reality. The quantitative characterization was performed using different methodologies found in the literature, and the results were compared with data presented by ABRELPE and SNIS. Ultimately, tools and strategies were proposed to minimize the negative impacts caused by the lack of construction and demolition waste management actions in the city, especially concerning the final disposal on inadequate locations in the urban area.
