Fuzzy Multicriteria Risk Assessment for Hazardous Waste Management: The Case of Istanbul

Abstract

A hazardous waste is waste that poses substantial or potential threats to public health or the environment. Hazardous waste management is an area of the waste management field concerned with the proper containment, management, and disposal of wastes which could be considered hazardous. In this paper, we use a multicriteria evaluation method, namely VIKOR, for various hazardous waste treatment alternatives under fuzzy environment. These alternatives are physical treatment processes, chemical treatment processes, thermal treatment processes, and biological treatment processes. Under the main criteria, economic, risks, and technical, we consider 11 sub-criteria. The fuzzy set theory let us use linguistic evaluations for the alternatives.
