The objective of this research concerns the evaluation of the economic impacts of strategies for the recovery of household solid waste in the city of Conakry based on tangible and demonstrated elements. To achieve this, four waste management scenarios served as a basis for the analyzes carried out. Collection was provided by the Albayrack company and transported to our work location. Careful manual sorting is carried out to characterize the waste.

The analysis of the physico-chemical parameters (density, electrical conductivity, average pH, moisture content of the fermentable material, lower calorific value PCI, carbon/nitrogen ratio) was carried out on samples obtained in applying the quartering method.

This characterization of household solid waste has made it possible to understand that the MSW of the city of Conakry are composed of: 44% organic waste, 20% plastic, 4% glass, 8% paper / cardboard, 5% metal, 5% wood and 14% other.

According to the results of the characterization of the DMA (sorting by category presented in figure 4) acquired from this study, we note that the DMA of the city of Conakry present a diversity of materials, the majority of which can be recovered or reused and by consequently the waste of resources decreases and pushes the development of the economy. Thus, this study allowed us to divide into 4 groups the MSW capable of being recovered or recycled and are presented as follows: Waste recoverable by composting, methanization, recycling and storable. These recovery strategies would reduce household solid waste dumps by 80% in the City of Conakry (Guinea).


Key words: Strategies, household waste, characterization, economic recovery and production cost.
