Methodology of selecting localizations for municipal landfill sites

Selection of localizations for municipal landfills belongs to complex multicriteria decision making problems. The paper presents a methodology developed for selecting localizations for municipal landfills based on Geographic Information System (GIS) technique coupled with Analytic Hierarchy Process (AHP). Joining these two methods makes possible incorporation of various quantitative and qualitative factors and solving the problem in a holistic way. GIS technique enables to include criteria resulting from the legal directives (so called rule-out criteria) and conducting spatial assessment in view of the area usability for waste deposition. In result we obtain areas suitable for waste deposition (predisposed) and the terrains where any localization of landfills is absolutely prohibited. AHP method was used to select the most suitable localization variant from the set of areas predisposed for waste deposition. For this purpose the structure of the task was presented as a developed hierarchy model with the scale of influence. Construction of the model required a proper selection of criteria and sub-criteria, and the scale of influence of individual sub-criteria on the considered localizations. Owing to the method of its construction the developed multi-criteria model with the scale of influence is a universal one and may be applied also for problems other ...

Elaborating the rules for selection of „recycling centre” localization using GIS –based multicriteria analysis

The amount of municipal wastes is growing every year and the negative social and environmental impacts became more severe. While integrating with the EU Poland was obliged to reach a 25% recycling level by 2007 and at least 55% level until 2014. Currently 25.6% wastes are recycled, which mainly results from segregation of processing wastes, withdrawing from use multi-use packaging and packaging originating directly from large retail outlets. Currently the recycling level of municipal wastes in Poland is 5.1%. About 1.5% is segregated from the mass of gathered mixed wastes. Poland will have to increase these levels in order to meet the EU requirements. The solutions adopted in the National Plan of Waste Management do not meet either the expectations of the society or local governments. Therefore, new methods of waste recycling should be sought. In the Scandinavian countries one of such methods is Communal Point of Selective Waste Accumulation, commonly known as “Recycling Centre”. The paper presents the methodology of selecting the localization for the “recycling centre” using GIS-based multicriteria analy-sis. The places were chosen on the basis of elaborated localization criteria indi-cating the excluded areas and the terrains predestined for the localization of a recycling centre. ...
