Gerenciamento de resíduos da construção e demolição: sistematização dos processos de separação e beneficiamento

Abstract

Construction and demolition waste (CDW) is generated from activities carried out by the construction industry and, when not disposed of correctly, can cause major inconvenience to the population and the environment. Therefore, considering the possibility of recycling some types of CDW, processing plants have emerged, responsible for transforming waste into recycled aggregates. However, for the process to be effective, waste must be managed from generation to final disposal. The aim of this study was therefore to determine the steps needed to properly manage construction waste. Research was carried out to find literature on waste management, as well as important laws and resolutions. Visits were also made to two different construction sites and a processing plant in order to observe the stages involved, from design to the treatment of the CDW. Based on the information obtained, a process flowchart was drawn up that covers all the stages that construction waste goes through when it is correctly handled and treated. It was found that the construction sites and the plant visited carry out the processes correctly, as described in the literature. It is important to emphasize that the flowchart drawn up can be used to support understanding of the complete waste management cycle, since no literature was found that covered it.
