One year after taking over urban waste management in Nouakchott, the Moroccan company ARMA finds itself in a delicate position. Despite the expectations placed in this specialized structure to sanitize the Mauritanian capital, the assessment after twelve months of operation is judged very insufficient by the country's governing bodies. The promise of a cleaner city seems to be colliding with a difficult operational reality, marked by a persistent accumulation of trash in the city's various neighborhoods. Faced with the scale of the criticism, the Ministry of the Interior has officially expressed its dissatisfaction with the service provider. The Mauritanian authorities are no longer just observing the situation: they have ordered the company to present a rigorous corrective action plan without delay. The stakes are high for Nouakchott, which is struggling to improve its public health conditions and living environment. While the official dissatisfaction is documented, questions remain regarding the technical means and real logistical obstacles the company faces on the ground. The effectiveness of the future action plan demanded by the state will be decisive for the future of this contract which, for now, is struggling to meet the expectations of citizens and local officials.
