Energy recovery and cleaner groundwater: techno-economic and environmental assessment of municipal solid waste management in the city of Bamako, Mali
The envisaged project’s theme is the projection of synergy of waste-to-energy in Bamako, Mali. It entails the positive interaction of: (i) waste reduction by means of anaerobic digestion and incineration (ii) and energy provision in the form of a secondary fuel (i.e. biogas) or electricity. This is achieved by iii) presenting the impacts of waste on the local water systems, (iv) a determination of the environmental and socio-economic analysis of waste-to-energy scenarios in comparison to the status quo, as well as (v) the installation and operation of a biogas pilot plant.
Technological waste-to-energy solutions have been developed in all directions and include thermo-chemical and biochemical technologies such as pyrolysis, gasification, incineration or anaerobic digestion. Industrial sized waste incineration and biogas plants represent proven technologies. Incineration units display the most widely used waste-to-energy technology around the world, but they are only sporadically applied in low-income countries. A skillful operation and management of waste holds the potential to reduce the emissions/pollution and increases the efficient energy recovery. In this project the waste to energy recovery routes will be analyzed for a selected site within Bamako municipality using the techno-economic and environmental assessment methods.
