Optimization of Sanitation in Conakry’s Markets: Challenges and Prospects

This article examines the optimization of sanitation and municipal solid waste management systems in the markets of Conakry, a critical issue for major African cities and undoubtedly one of the environmental challenges with significant adverse impacts on human health.

The study analyzes waste management practices in Conakry’s markets, taking into account the specific types of products traded, in order to propose sustainable management strategies. The analysis is based on interviews conducted between February and June 2024 and April 2025 with municipal and market authorities, as well as vendors and customers. In addition, a structured questionnaire was designed to assess the current state of waste management in the major markets of Conakry.

The results reveal a proliferation of illegal dumping sites and the absence of a systematic waste collection system, thereby exposing market users to continuous health and environmental risks. The study also highlights the main constraints affecting waste management, as well as the various stakeholders involved. Furthermore, there is no effective policy for waste collection or for the segregation of solid and liquid waste streams. These findings underscore the urgent need to propose an optimized and integrated system to improve waste management in Conakry’s markets.
