Application of analytic hierarchy process and multicriteria decision analysis on waste management: A case study in iran

Authors (for correspondence)


This research compares the various waste management strategies in Tabriz, Iran, and selects the best one by a decision-making method. Selection the best strategy is conducted based on the Multi Criteria Analysis (MCA). In this regard, the Analytic Hierarchy Process (AHP), a mathematical technique for multicriteria decision making, and the Multi Criteria Analysis which is a developed decision-making tool have been used. This research compares four waste management strategies including various practices such as Source Separation (SS), Biological and Mechanical Treatment (BMT), Refused Derived Fuel (RDF), Incineration and Landfilling. There are mainly eight criteria weighted based on the AHP method to select the best strategy. These criteria consist of required land for waste management, energy recovery, investment and operation costs, income to cost ratio (benefit), environmental impacts, and complexity of implementation and operation of process, public acceptance, and recycling materials. The results of this study demonstrate that the first strategy provides the best solution for waste management which includes SS, Compost production, BMT, RDF and Landfilling. Finally, study suggests various solutions that minimize environmental impacts and social cost and improve the public acceptance. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 810–817, 2013
