Use of construction and demolition waste as an income generator in socially vulnerable communities
According to the UN, the world population has progressed in the coming years, with the forecast of reaching 10.87 billion people in the year 2100. As a result of this increase, it is necessary to build new housing and commercial units, as well as an extension of the existing infrastructure. Therefore, more and more demands will be placed on the environment, sometimes in the extraction of mineral resources, sometimes in the disposal of waste from the construction and demolition process. Due to this, various sectors of society are mobilizing to proportions that aim to mitigate these impacts. One of these solutions is the promotion of the circular economy in the construction industry, which seeks to use the waste needed by the industry itself as raw material in new buildings. In addition to reducing the extraction of mineral resources, this solution can also reduce waste disposal, as well as providing a financial gain to the process. This gain can be reversed in income generation for populations in social vulnerability. Given the above problem, this dissertation aims to analyze an existing bibliography, as well as to analyze the data collected in five neighborhoods in the city of Recife, classified as an area with social vulnerability, for technical-economically viable proportions that aim to provide the use of construction and demolition waste, generated by these communities, to provide income generation and the supply of construction materials at an affordable price.
