In developing countries, millions of tons of Construction and Demolition Wastes (CDWs) are lost every year due to lack of knowledge of the recycling significance and/or procedures. Despite the high value of CDWs, high percentage of this waste is either dumped illegally or disposed in the landfills. Disposal methods should consider saving natural resources and maintaining the environmental conditions through maximizing the value of CDWs. This research aims at choosing the most sustainable disposal alternative using Multi-Criteria Decision Making (MCDM) Process. The research introduces a list containing the most relevant and significant sustainable indicators that affect the selection of alternative for disposal of CDWs. Then, it determines the composition of demolished waste materials and estimates the generation rate of each demolished material inside the city of Cairo with corresponding alternatives. Finally, fuzzy TOPSIS techniques applied considering the significant indicators on each alternative to rank and choose the best alternative for disposal of CDWs
