Quantitative and qualitative analysis of the construction and demolition waste generated in Belo Horizonte/MG

Abstract

Civil construction is one of the economic sectors that most impact the environment. The volume of construction and demolition waste (CDW) generated in cities and their inadequate disposal is factors that potentiate environmental degradation. The objective of the present work was to perform a quantitative and qualitative analysis of the production of CDW in Belo Horizonte, MG. As part of the qualitative analysis, a survey was carried out of the current state of management of CDW in the city with a view to understanding the feasibility of using CDW recycled as input in the construction industry of the metropolitan area of ​​Belo Horizonte. After this step, the CDW sample was collected and characterized at the rubble recycling station located at BR040. The sampling method was used according to related norms. Through the gravimetric analysis, it was observed that 95.5% of the total CDW produced is type A, which indicates a great technical and economic potential for reuse directly in the construction industry. Therefore, the results indicated the need for guidelines for the application of these residues back in the civil construction and for the creation of environmental education policies.
