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

Abstract

La production des déchets est inhérente aux activités humaines, qu’elles soient domestiques, agricoles, industrielles ou commerciales. A la faveur d’une urbanisation galopante et de ses corollaires, l’assainissement et la gestion des déchets sont devenus des préoccupations importantes. Si la situation de déchets ménagers semble connaître une évolution dans la capitale burkinabé, ce n’est pas le cas pour les déchets des industries et des transports comme les huiles usées. Ce travail avait pour objectif d’étudier la production et la gestion des huiles usées dans la ville de Ouagadougou. La méthodologie de cette étude a été basée sur des observations et des enquêtes spécifiques auprès des groupes cibles. Les résultats obtenus ont montré qu’environ 5 721 459,45 litres d’huiles usée ont été générées à Ouagadougou en 2017. Les huiles usées sont exportées à 11%, utilisées par l’industrie locale à 67% et à 22% à des fins personnelles diverses. Les conséquences sont diverses sur l’environnement. Il apparaît nécessaire vu les différents usages prohibés que le domaine soit mieux réglementé.
 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.

“…This can promote an increase in the number of microorganisms in the environment, leading to an accumulation of soil organic matter in the tree rooting zone compared with open areas [20]. Indeed, studies have reported that Guiera senegalensis and Piliostigma reticulatum have been identified to promote fungi, microbial diversity and litter decomposition [5]. The presence of micro-organisms in the tree rooting zone is due in part to the fact that phosphorus, an essential ecosystem element, is not present in the soil [21,22].…”

“…Indeed, the choice of species, their density and their arrangement in cultivated plots depend on the socio-economic and ecological benefits they bring to the population. Most farmers in the semi-arid zones of West Africa consider trees to be an integral part of the production system [4,5]. Worldwide, studies on these combinations have attracted the attention of many scientists.…”

“…In order to prevent these negative effects, environmental protection must be integrated into the project as soon as possible. This is also justified by Law No.006-2013/AN on the Environment Code in Burkina Faso, which stipulates in article 25 that any activity likely to have significant environmental impacts is subject to an environmental impact study or notice (Yelemou & al., 2021). Action 2: Drainage or cleaning of water bodies.…”
