Mapeamento de Pontos de Deposição Irregulares de Resíduos de Construção e Demolição da Cidade de Caruaru, Pernambuco

Abstract

With the urban development of cities, there is an increasing need for raw materials, especially for housing construction. One of the challenges faced by sustainability, the responsible bodies, the environment, and the construction industry is the proper management of construction and demolition waste (CDW), because increasingly, these CDW are deposited irregularly in cities. This paper presents the mapping of 410 points of irregular disposal of CDW in the city of Caruaru, Pernambuco State, distributed between large and small works, being georeferenced through the software QGis3.16.14. These points were related to the public facilities of the city (schools, health units, squares, and parks), with the income of the population, vegetation and waterways. Most of the CDW disposal points came from small renovations of local houses, being Class A waste (405 points). In lower-income areas, 79.27% of the points cataloged (385 points) were in low-income neighborhoods. Regarding the number of household density, 58.8% of the points (241 points) are children in average sectors (from 20 to 160 inhabitants per hectare). A total of 9.3% of points (37 points) were located less than 50 m from public use equipment. Only 35 points focused on green areas, and 20 points on water bodies.
