Sustainable management of construction waste in the Metropolitan Area of Misiones

The Metropolitan Area of Misiones does not have an adequate treatment of construction and demolition waste (CDW) by the municipalities that comprise it, so they do not reach the bases of sustainable development. The aim of the article was to present a model for the quantification of CDW, developing a case study corresponding to the foundations of 154 social housing units located in the reference area by applying the Weighted Transfer Method. The adoption of this method was based on using different construction cost bases and quantifying the CDW expected to be generated in the work, obtaining the information of each element, material of the specifications and the spreadsheet, and the project budget and then organizing it according to the codification of the European Waste List. Finally, the mathematical model generated from the Weighted Transfer Method was applied to convert the resources consumed into the volume of concrete, steel and soil waste generated during the foundation of 154 social housing units. It was concluded that the model fulfils the premises of the work and that its application will support decision making regarding CDW management.
