Although the above-mentioned Accepted: methodology was applied to three different areas (Western, South-western and East- 30 May 2018 ern) of Sicily, in this paper, we present the results of the western sector. The first Available online: step consisted of the division of the study area in excluded and potentially suitable 30 June 2018 sites, on the basis of the Italian current legislation. The suitable sites were subse- Keywords: quently re-evaluated based on additional criteria in order to choose the most suitable Municipal solid waste ones. This second step consisted of a multi-criteria analysis based on a scores and Landfill Analytical hierarchy process weights system. The Analytic Hierarchy Process (AHP) was applied to estimate the Geographic information system relative importance weights of the evaluation criteria. The suitability for landfill siting Sicily was finally evaluated with the aid of a simple additive weighting method.
