Abstract :
The management of urban waste (GDU) is a critical challenge in Sub-Saharan Africa, particularly in Yaoundé,
where rapid urbanization exacerbates insufficient infrastructure, service fragmentation, and the proliferation of illegal
dumps. With a recycling rate below 4% and a composition dominated by organic matter (61-65%), the current system
generates significant environmental (leachate pollution, methane emissions) and socio-health impacts. Facing the objective
of the Yaoundé Urban Community to reduce landfilling by 70% by 2030 through an investment of 80 billion FCFA
(including a sorting center, a methanization unit, and a plastics processing unit), this study is essential. It aims to design an
adapted urban waste management center by integrating architectural, urban, social, and environmental dimensions.
Through a critical analysis of African models (Dakar, Nairobi, Kigali) and circular economy strategies, this work defines
the optimal architectural principles (flow organization, safety) necessary to guarantee a functional, sustainable, and well-
integrated infrastructure within Yaoundé's constrained urban context.
