This present study aims to evaluate the quantity of household waste rejected by type of habitat and by household size for 6 days for the city of Conakry in the Republic of Guinea. This study focused on the five (5) municipalities of the city of Conakry, namely: Matoto, Matam, Kaloum, Dixin and Ratoma. The habitats were classified by size as follows: high standing, medium standing and low standing. The main results obtained during this research are as follows: for the Municipality of Matoto, the quantity of household waste rejected during 6 days at the level of the High standing habitat is (99.1 kg), that of Low standing is 94.4 kg and for the Medium standing is 87.7 kg, although the household size at the High Standing level is smaller nine (9) people compared to the other two with eleven (11) people respectively. This difference could be due to the difference in the purchasing power of the constituent members of the different levels that is to say simply the difference in the standard of living. For the Commune of Ratoma, the greatest quantity is observed at the level of the Low standing (99.8 kg) followed by the High standing with 94.7 kg of garbage. This situation can be explained by the size of the Commune with a large population, as well as the large number of sources of waste production that are the many markets and the many units of packaging factories of all kinds.
