Project
context
the former akouédo landfill transformed into an urban park
Located in the heart of Abidjan, the Akouédo landfill, which has been in operation for almost 50 years and covers an area of over 100 hectares, has received almost 18,000 tonnes of waste. Having reached saturation point, the landfill presented multiple health risks and was definitively closed in 2018. With the aim of returning this space to the people of Abidjan, the landfill is being transformed into an urban park, a veritable green lung for the city. To achieve this, initial earthworks and servicing have been carried out to install a water purification and fermentation gas recovery system, and the biogas will be converted into energy. The park is home to a sports and recreation center, several pathways and a cultural hub centered around the Maison de l’Environnement.
The main aim of rehabilitating the Akouédo site is to reduce the transfer of pollution from the landfill to the environment by containing the entire waste mass.
The containment technique involves reshaping the surface of the waste to create domes and slopes, installing a watertight cover to divert rainwater into peripheral ditches, and a whole circuit of pipes to collect the leachate and biogas produced by waste fermentation.
