Abstract
The Kinshasa Technical Waste Landfill Center (TWLC) is a 250-hectare space erected to receive and bury waste from nine municipalities in the city of Kinshasa during the period from 2010 to 2017. Four years after the work stoppage, it is currently colonized by vegetation. This research consists in evaluating the impact of waste burial activities on the flora of MPASA. The sampling sites selected are the surrounding environment serving as a control, the lockers in which the waste was buried and the lagoon basins which received the leachate resulting from the decomposition of the waste in the lockers. The floristic and soil samples were respectively taken for identification and laboratory analysis. The results reveal a discrepancy between the sites. Floristically, the lockers are colonized by 33 plant species; the surrounding environment has 28 species and the lagooning basins, pauci specific, record only 4 species. On the pedological level, the pH is acidic in the surrounding environment while it is alkaline in the lockers and lagoon basins.

Summary
Each era has had its mode of treatment and its specific problems. Landfilling was the solution that initially seemed to be the most practical, moving over time from wild dumps to controlled dumps; the latter receiving bulk waste of all types and ending up being a threat to the environment themselves [1]. Considering waste management as a problem of public hygiene, the authorities mainly focus on the cleanliness of public spaces and the disposal of waste outside cities. The strong waves of population growth from the 1960s and the development of non-regulatory housing districts, in Africa, made the problem of waste an international environmental problem issue at the same time an opportunity for the private sector.
