In the framework of the 'SANITA Villes Propres' programme (2019-2023) financed by the European Union and executed by ENABEL, Hydroconseil is supporting Ecogeos in Guinea to carry out a waste characterisation (quantity and composition) in Kindia and Conakry. The results of this study will inform the elaboration of solid waste master plans for Greater Conakry (2021-2040) and for the urban area of Kindia (2021-2030).
