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.
