Summary: The construction of landfills is a no alternative option, since a landfill is always necessary independently of the specific waste management system that will be developed. The criteria that must be met to allocate a landfill are various and in many circumstances conflicting. For that reason the result is not univocal, it depends on the criteria and the methodology used together with its restrictions. The suggested methodology utilizes GIS technology for the input, the management and the visualization of the geographic data while fuzzy logic is used for the analysis of the data and the evaluation of the final results. The basic elements of the fuzzy logic methodology as well as its potential in the specific problem are described. A case study took place in one Governorate in Egypt, one of the twenty-seven country administrative units. The results drawn up by fuzzy logic are compared with that of the classical Boolean approach of data analysis.
