- In Chad, the current solid waste management mechanism faces multiple socio-economic, technical, institutional, legislative and operational constraints. The lack of a reliable municipal solid waste collection service and the inadequacy of collection vehicles adapted to local conditions, have favored the anarchic creation of dumps at the feet of houses, on the edges of certain stagnations of water in the city, along the roads and in the drainage ditches. For effective waste management, precise data on their generation and composition is required, which is important for making decisions about the appropriate waste management mode. Currently, there is no available data on the production and composition of municipal solid waste (MSW) collected in N'Djamena (Chad). This article expresses an attempt to characterize municipal solid waste produced in the city of N'Djamena, the capital of Chad. An investigation into the conduct of housework was carried out. The determination of the characteristics of the municipal solid waste was made, based on the samples that were collected at the level of the "improvised dumping" of Lamadji (N'Djaména), during the two main seasons, dry and wet. After sorting into various components of the collected sample, the weight and volume of each component were measured and recorded. The average production of DSM is 0.48 kg / day / person by weight, of 1.536x10-3 m3 / day / person by volume with a density of 312.5 kg / m3. The results show that the largest proportion of urban solid waste is composed of biodegradable and recyclable waste. For efficient management of waste streams, value-added processes such as composting, energy recovery and recycling must be practiced in the future. They could probably contribute to the considerable reduction of waste streams going to landfill.
