The subject of this paper is the application of a morphological classification of MSW in the city of Rio de Janeiro based on the German recommendation DGGT (1994) – E 1-7 GDA. This recommendation deals with the identification and description of waste according to aspects of waste mechanics. This will give the environmental control agency and companies responsible for final waste disposal more comprehensive information about the geotechnical characteristics of the materials. First, the waste is described in relation to type, identification and its condition. After determining the type of waste, indications for analysis in groups of substances are obtained in a second step. The results have shown that in the Brazilian sample the percentage of waste with dimension 1 and dimension 2 is higher than 30% in weight, which is a favourable indicator in the MSW landfill analyses in view of stability. The results found using this classification furnish information for a better analysis of slope stability of MSW landfill by including the fibre reinforcement effects. It is also important for projects concerning waste recycling.
