Gerenciamento de resíduos de construção e demolição: proposta de RCD Social para Recife - Pernambuco

Abstract

Construction and demolition waste (CDW) in Recife-PE has been underutilized or even discarded, wasting opportunities for new uses that mitigate the negative impacts of Civil Construction on the environment in which it is inserted. This research addressed the management of construction and demolition waste in the city, starting from the questions of: (a) how the CDW can be reused in the self-construction of housing by the low-income population; (b) what mechanisms can be created and associated with management so that the CDW are reused in the self-construction of housing by the low-income population; and (c) which implementations can be added to the Conecta Recife application to improve CDW management, facilitating collaboration between public authorities and citizens. For this, it had the general objective of proposing the creation of the Social CDW as a mechanism and instrument associated with the management of solid waste from civil construction in the city of Recife/PE, aiming at the access of the low-income population to recycled and/or reusable construction and demolition materials. To carry out the investigation, descriptive, exploratory, and explanatory studies were made. As technical procedures, documental research and survey were adopted, and as data collection instruments, interviews and forms were applied. The research universe comprised 3 (three) fields within the context of the management of CDW in the city: governmental instance (Autarchy of Urban Maintenance and Cleaning – EMLURB); CDW collection and recycling company (Ciclo Ambiental); and low-income citizens from three communities in Recife. The main result is the proposal of the “Social CDW for Recife- PE” consisting of three associated tools: ecopoints and ecostations structure, social warehouse and Conecta Recife digital platform. The Social CDW has the potential to contribute to improving the flow of CDW, organizing them for recycling and reuse, with constant feeding of a digital database existing on the platform, which will give access and possibilities to low- income users who need material to construction or improvement of their home. In addition to mitigating the negative environmental impacts caused by civil construction, waste transformed into recycled and reusable materials can contribute to social improvements for citizens and to the circular economy in civil construction.
