This study examines the sustainability of local initiatives for the valorization of plastic waste in Bukavu and their impact on youth employment creation as well as urban sanitation. For several decades, the city has faced major challenges related to poor plastic waste management, undermining urban quality of life and threatening aquatic ecosystems. In a context where plastic waste is increasingly perceived as a resource, the study draws on 34 semi-structured interviews and observations conducted with stakeholders involved in the plastic recycling value chain. The findings reveal that many youth-led organizations and enterprises are engaged in the collection, disposal, and transformation of plastic waste. Their initiatives range from manufacturing utilitarian products from recycled materials to offering training on waste management and sanitation. These efforts have led to the creation of several green jobs, thereby contributing to the improvement of the city’s cleanliness. However, these initiatives remain fragile due to multiple challenges hindering their long-term sustainability. Grounded in the theory of the circular economy, the study recommends the establishment of an innovative ecosystem that fosters collaboration among all stakeholders in the sector. Such a framework would help optimize the benefits of plastic waste valorization, create more green jobs for young people, and sustainably improve urban sanitation in Bukavu.
