Gestão de resíduos sólidos de construção civil, podas e insensíveis em Brasília, DF: mapeamento, caracterização das áreas de descarte e avaliação das políticas públicas

Abstract

The growing urbanization in Federal District and adjacent regions, combined with the lack of adequate equipment for the disposal of solid construction waste (RCC), has generated a significant increase in irregular disposal areas. The present study aims to characterize the RCC disposal areas, especially in Vicente Pires, Taguatinga, 26 de Setembro and Areal/Arniqueiras, and evaluate the effectiveness of public policies aimed at managing this waste. The methodology included field surveys, analysis of satellite images and consultations with data from the Integrated Civil Construction Waste Management Plan (PIGRCC). 537 irregular disposal points were identified, with emphasis on the collection of 480 tons of waste in just one day, during the Federal District Government's operation. The analysis revealed that the absence of Voluntary Delivery Points (PEVs) in strategic regions, such as Vicente Pires and 26 de Setembro, worsens the problem of inadequate disposal, causing severe environmental impacts, such as obstruction of drainage networks, flooding, soil contamination and proliferation of diseases. The results indicate that current public policies, although they exist, are insufficient to contain the spread of the problem, being necessary include expansion of PEVs, greater inspection, environmental awareness campaigns and the use of technology, such as drones and cameras, to monitor critical areas. These actions are essential to mitigate environmental impacts and promote sustainable management of solid construction waste in the areas studied.
