Evaluation meso-economico-environnementale de la gestion des dechets solides de la ville dʹAzemmour (Maroc) (Evaluation meso-economic-environmental management of solid waste from the city of Azemmour (Morocco))

As part of this study on the economic evaluation of environmental impacts related to solid waste management of the urban municipality Azemmour, the cost of environmental degradation due to the current management of household and similar waste is evaluated to 0.73% of value added (VA) of this municipality. The groundwater pollution contributes 0.17% of VA, inefficiencies related to waste management is estimated at 0.43% of the VA, the degradation of air contributes 0.05% of VA and land degradation landscape and contributes 0.07% of the VA. The remedial actions recommended for better solid waste management is $ 0.4082% of the VA of the urban municipality Azemmour. Thus waste sectors, water, air and soil and landscape contribute respectively by 0.18%, 0.12%, 0.05% and 0.04% of the VA. Investments for these sectors are beneficial in the long term. In effect, for every 1 USD expended one gains 2.36 USD in the area of waste, 1.55 USD for the ground segment and 1.44 USD for the water sector. The recommended management system is more economical even if it requires investment costs and higher operating costs for its implementation. According to our calculation amortization of initial investment, spread over 20 years, is possible from the tenth year of operation. Thus the recommended management system will become less environmental impact than the current system and it will be economically more viable and profitable long term.
