ANALYSIS OF THE COSTS OF CONSTRUCTION WASTE IN RESIDENTIAL BUILDING WORKS IN CITIES IN THE NORTHEAST OF BRAZIL

This article presents a survey of the economic aspects of managing Civil Construction Waste (CCW) on construction sites in five cities in Northeast Brazil, causing expenses in the production and profitability of buildings. From collecting data from eighty-four projects relating to waste management, information was obtained on unit cost for disposal, classification of materials, built area and construction stage. It was found that CCW is predominantly Class A and can be reused as aggregate. However, correct segregation is not carried out on-site, resulting in increased values. Furthermore, it was noticed that there is no proportional relationship between the built area and the waste generated. Finally, the inefficiency of management systems was observed due to the disregard of some practices, although most buildings are certified by quality management programs (ISO 9001). Therefore, one of the simplest ways to mitigate costs can be through the application of efficient management, which is associated with the improvement of professionals in the area and raising awareness of the product used.
