throughout the process leading to the waste. In 2010, the rate of access to a healthy environment in urban areas in the DRC was around 42% according to the report on hygiene and environment in urban areas (Lelo. N, et al, 2004). This situation has a negative influence on the health of the surrounding population and on the ecosystems. After independence, the communes of the city of Kinshasa in the Democratic Republic of the Congo are already experiencing sanitation and hygiene problems. The city of Kinshasa produces seven thousand tons of waste every day from households, markets, public places and businesses. This includes scrap metal, produce, and plastic bags and garbage (Mindele, 2016). In his outlook, he advocates for a substantial reduction in landfilling or current practices (open dumping, dumping in waterways, burying in plots, incineration) in household waste management in Kinshasa. For him, it is necessary to promote large- scale recycling of organic matter for energy recovery and fertilization of degraded soils. I.

The city of Kinshasa occupies a vast plain that constitutes a basin bordered by hills. The vegetation of Kinshasa is essentially made up of savannah dotted with shrubs with the urban pressure, it is currently located in the region of hills and on the plateau of Kwango. The soils of the city of Kinshasa are essentially sandy belonging to the tropical soil group, with some coarse elements. They are sandy soils with low clay content (less than 20%) and very acidic, but rich in iron and aluminum (Al2O3) subjected to the action of a hot and humid climate. In the city of Kinshasa, there is a particular ecoclimate of the humid tropical type AW4 according to the classification of KOPPEN, that is to say a climate with a dry season of 4 months from mid-May to mid- September and a rainy season from mid-September to mid-May (Ntombi et all, 2004).
