摘要
The main objective of the work is to search for relevant indicators for assessing the impact of waste on water quality and their contribution to climate change. The leaching test applied allowed accelerated access to the water-soluble material that can be mobilized in the various fractions of household and similar waste from the city of Sokodé, a material that can be salted out by leaching and leaching processes in nature. It has thus made it possible to evaluate the reactivity of the waste by promoting access to the composition and the quality of the released organic matter and to facilitate a follow-up of the recovery of the biological activity over a period of 120 hours. The study of physicochemical quality of the waters of Kpondjo River has shown a link between the deterioration of the quality of the river's water and the manner of waste management. The 17541 m3 of methane generated by sludge from slaughterhouses and fermentable fractions of solid waste, could contribute to climate change. Indeed, a composting valorization of biodegradable fraction of solid waste that is generated in this town would reduce the methane produced by this waste and thus help to reduce global warming trends.
