Evaluation of irregular construction and demolition waste (CDW) disposal in Frederico Westphalen – RS

Abstract

From the intensification of generation and the environmental problems caused by the irregular provisions of construction and demolition waste in Brazilian municipalities, public administrations have been looking for ways to control and soften these aggravating factors. In this sense, this work had the purpose of presenting a diagnosis of the current situation of the RCDs inadequately disposed in the municipality of Frederico Westphalen, through the survey of areas of clandestine discards. A total of 46 areas were found with clandestine eviction, most of which are of small size and, after the three inspections, were regularized, active or inactive. Due to the large incidence of areas that have not yet been regularized (34.8%) it was evident the lack of effective control of these irregular dispositions, reaffirming the idea that there is a need to implement a municipal management plan for this class of waste, characterizing the deposits as clandestine RCD areas. There were also numerous environmental impacts, among them, partial interruption of street and public pavement, presence of other types of waste, pollution and contamination of permanent protection areas. This data collection can serve as an aid to public agencies for the development of actions and supervision guidelines in these areas, in order to better manage these wastes.
