Abstract
As the percentage of segregated waste, taken as individual indicator, is insufficient to measure the virtuosity of a Municipality
waste management, a multicriteria indicator has been developed to broaden the horizon of the analysis of waste management
performance. The aim of this study is to experiment a new and easy–to-use methodology for the evaluation of Municipalities
virtuosity in waste management, built from Public Administrators to verify the responsiveness between their ideal guidelines and
their real applications. The identified criteria are eight: percentage of segregated waste collection, production of unsorted waste
per capita, total production of waste per capita, service costs, environmental impact of the waste collection and treatment system,
traceability of Municipal Solid Waste's fate, involvement of population, citizen's convenience. Scores given to each criterion
were assigned by experts in each field and then normalized [0-1]; weights were determined applying Pairwise Comparison
method to Public Administrators of municipalities selected as a case study. For each Municipality, a score for each criterion is
assigned and, subsequently, multiplied by the weight given to the criterion itself. The indicator provides a wide spectrum
analysis, marking the state of the art, the scope for improvement and deficiencies of each area of analysis; thus to become an
effective decision support tool for Administrations. This tool was, applied to a case study, returning results in terms of virtuosity
far different from those obtained in terms of percentage of recycled waste alone, thus highlighting the importance of a
multidisciplinary approach to the issue.
