Application of MCDM techniques in municipal solid waste treatment and disposal method selection

摘要

MSW treatment and disposal method selection is a multi-criteria decision-making (MCDM) problem. This research attempts to select the appropriate MSW treatment and disposal method by using Fuzzy Delphi, AHP and TOPSIS techniques. Currently, in India, MSW is collected and directly disposed into the landfills without any kind of treatment and segregation. Mumbai is one of the most densely populated cities of India. Most of the generated waste is sent directly to the disposal sites. An average of 14,500 metric tonnes of solid waste is produced daily in Mumbai (MPCB, 2014). There, MSW composition consists of approximately 60% organics, 8% plastics, 6-8% paper/cardboard, 6% metal, 6% glass, and 10% unclassified (MPCB, 2014).
