Fuzzy Analytic Hierarchy Process in Environmental Management and Estimating Construction Waste Generation Index in Building Construction Projects; Case Study Tehran

Due to the occurrence of abnormal in many cities like Tehran cause to make global environmental change as a concept of sustainable development becomes more and moreimportant. There is an increasing pressure on the construction industry in Tehran city to reduce costs and improve the quality of our environment. The fact is that both of these goals can be achieved at the same time. Although construction and demolition constitutes a major source ofwaste in terms of volume and weight, its management and recycling efforts have not yet seen the light in Tehran city. This research investigate in estimating construction waste generation index in building construction projects by using Fuzzy- AHP. Objective function of this model is toreach recycling efforts leading to the minimization of the total construction and demolition waste that is currently landfilled in Tehran city. This paper presents the current status of construction and demolition waste disposal system in Tehran city and identifies the potential problems to theenvironment, people and economy by Fuzzy-AHP model. Then, it investigates alternative solutions to manage and control this major type of waste in an economically efficient and environmentally safe manner. Next, the paper describes the feasibility of establishing aconstruction and demolition waste recycling facility in Tehran city. It concludes by highlighting the major benefits problems with such a recycling facility and green operation performance.
