This Thesis analyses the problems faced by the Lagos State Government, in coping with an increase in Municipal Solid Waste (MSW) management and because of population growth and an increase in standard of living of Lagos State residence. The objective is to estimate the capacity of energy recovery and material recovery in a more sustainable and environmentally friendly ‘waste to energy’ models.
Scenario 1, analysed the present unsustainable ‘waste to landfill’ management practice, 72% of total MSW is landfilled and less than 5% is recovered via energy and material. Scenario 2 produced 2.23Mt/a of (Refuse Derived Fuel RDF) and 0.09Mt/a of Tire Derived Fuel (TDF) for energy recovery in the Cement kiln from MSW. Also, 0.67Mt/a of Biofertilizer was produced in Scenario 2. Scenario 3 produced an estimated amount of Biogas from 1.61 Mt/a of biodegradable waste and a potential huge amount of Biofertilizer from biowaste.
Due to advanced waste treatment option employed in Scenario 2 and 3, waste to landfill reduced from over 72% of total MSW in Scenario 1 to 8% in Scenario 2 and 3. The overall goal of this thesis is to reduce the amount of waste to landfill, through different mechanical (Incineration) and biological (Composting, Anaerobic digestion) waste treatment options.
