Geographic Information Systems supported by multi-criteria decision analysis to indicate potentially suitable areas for construction and demolition waste disposal

In Brazil, the disposal of construction and demolition waste (CDW) quite often occurs in inadequate places, resulting social, economic, environmental problems. This reflects need for selecting appropriate areas this type waste. These must follow local standards regulations to protect human health environment. Considering that, study is intended indicate potentially suitable CDW landfill deployment, known as Class A supported by a GIS-MCDA based model. The technique, used basic tool identify areas, has several advantages, such low cost, reduced spatial data subjectivity, fast decision-making process. place chosen Urban Central Core Metropolitan Area Curitiba. By integrating GIS with MCDA techniques research study, it was possible region.
