The choice made on this subject is explained by the mismanagement of solid waste in the city of Kinshasa which constitutes a major problem for the latter. This is how we assessed the knowledge of the population of the Mbuku district in the Municipality of Kisenso on the management of solid household waste, with a view to trying to set up an integrated management system for this waste through the recovery or recycling. This led us to organize a separate collection of solid waste in 21 households in this neighborhood. The solid waste thus collected was categorized into organic and non-organic waste, then weighed separately according to the fractions. The organic waste was recycled into compost and the non-organic waste sent to the various respective recovery sectors. In this district, as the average household size is 17 people, waste production is estimated at 0.3 kg/person per day. The results of the physicochemical analyzes of the compost produced comply with standards and literature for mature, good quality compost. The compost produced played a big role in the fertility of the soil for growing amaranths which we used as a test. To remedy this situation, a diagram summarizing the systems to be implemented for integrated and sustainable management of solid household waste in the district was proposed as a project.
