Multi-criteria decision analysis in strategic planning of waste management

Multi-Criteria Decision Analysis (MCDA) or Multi-Criteria Decision Making (MCDM) is a discipline aimed at supporting decision makers faced with making numerous and sometimes conflicting evaluations. MCDA aims at highlighting these conflicts and deriving a way to come to a compromise in a transparent process. In this study, MCDA was used to attain a systematic approach to strategic planning of waste management, i.e. selection of a site for waste management centre. Ecological, spatial and social criteria involved the following: population density of the area in the neighbourhood of potential locations, population density along the roads intended for transport of waste to the landfill site, impact of construction works on the environment, impact on the previous intention of the area, natural characteristics of the location (geological, seismic, hydrogeological…), biological and environmental characteristics of the location and surrounding area, gases and noise emissions and their distribution in the surrounding area under atmospheric conditions. Criteria have been considered and evaluated whereas 1 was taken as the lowest mark and 5 as the highest for every potential location on the basis of available data. For the comparison of potential landfill locations, on the basis of their overall environmental impact, MCDA was applied. As a measure for evaluation of the importance of particular criteria in the process of comparison and attaining of waste management centre, weight factors were determined. Calculation of total mark for each landfill location by summarizing the results of particular site was performed by criteria application and weight factor determination.
