ABSTRACT: The gravimetric composition of solid wastes is essential for the identification of the best municipal waste management and management program. Therefore, data on the gravimetric composition allow the knowledge of the factors that determine the origin and formation of these residues. The present study aimed to analyze the gravimetric composition and the per capita generation rate of solid household waste. The methodology used consisted in the collection, separation and weighing of the organic and inorganic residue during 14 days in three Alagoan municipalities: Teotônio Vilela, São Sebastião and Arapiraca rural area. In Teotônio Vilela and São Sebastião, one residence per municipality, with 04 residents per household; and in the municipality of Arapiraca were two residences, one with 05 and the other with 04 residents. The calculation of the per capita generation rate was performed after obtaining the values of the weights of the residues, divided by the number of inhabitants of each locality. Regarding the results, in the gravimetric composition of the analyzed samples, half presented the percentage of the organic residue superior to that of the inorganic residue, average of 57,2%, above the national average; and the rate of per capita generation of household solid waste, the highest rate was 0,57kg/hab./day and the lowest was 0,1 kg/hab./day. It is concluded that the differences found are associated to the locality of the residence and habits of the residents.
