Production et gestion des huiles usées de la ville de Ouagadougou, Burkina Faso

Abstract

Waste generation is inherent in human activities, whether domestic, agricultural, industrial or commercial. Thanks to rampant urbanization and its corollaries, sanitation and waste management have become major concerns. While the household waste situation seems to be changing in the Burkinabé capital, this is not the case for industrial and transport waste such as used oils. This work aimed at studying the production and management of used oils in the city of Ouagadougou. The methodology of this study was based on observations and surveys specific to the target groups. The results obtained showed that approximately 5,721,459.45 liters of used oil are generated in Ouagadougou. Used oils are exported at 11%, used by local industry at 67% and 22% for various personal purposes. The consequences for the environment are diverse. It appears necessary, given the various prohibited uses, for the area to be better regulated.
