Abstract :

This research proposes a sustainable solution to the pollution caused by polyethylene terephthalate (PET) plastic waste in the city of Kinshasa, while supporting the circular economy. The main objective is to valorize this waste by transforming it into ecological trash cans called "Poubob."The methodology used combines in-depth documentary research with field investigations conducted at the University of Kinshasa and the Kalamu River, resulting in the collection of 80,400 plastic bottles. These were used to produce 300 ecological trash cans over a period of 2 years and 3 months. The results show that "Poubob" is designed for the selective sorting of plastic waste and has innovative features, such as its recyclability and adaptability for other products. The environmental impact is significant, with a visible reduction of plastic waste in the targeted areas and increased awareness among households about eco-friendly practices. In conclusion, this study demonstrates that plastic waste can be transformed into useful products, such as ecological trash cans, thus contributing to more efficient waste management in Kinshasa, reducing pollution, and promoting sustainable development.
