Environmental management in the major cities of the Democratic Republic of the Congo is currently facing a new challenge: the sheer volume of solid household waste abandoned in the streets, the non-biodegradability or toxicity of some of it, the length of time it remains undisposed of, and its impact on the environment.Kinshasa is the country’s capital. It is an undefined geographical entity within the boundaries of a province, with a population of over 8,000,000. The mentality of the Congolese population has changed since the recent past, during the era of the rural exodus and the great movements of rural populations to the cities. This period transformed the vision of the black man in Africa. It’s a vision that’s very different from that of the man of the colonial era in terms of understanding the notion of public hygiene. As a result of this new behavior, the city’s citizens are generating and abandoning more and more waste on the streets and in their homes.
