Innovative landfill bioreactor systems for municipal solid waste treatment in East Africa

Landfilling is the dominant disposal method of municipal solid waste in developing countries particularly East Africa mainly because of low operation and maintenance costs and availability of land. Concerns associated with landfills are the gaseous and liquid emissions.

In this thesis four innovative landfill bioreactors were identified, elaborated and evaluated based on literature regarding the construction and performance of landfill bioreactors, experimental research on pilot plant scale, desk studies regarding biological conversion, modeling of the biodegradation rates and biogas production of landfilled waste.

The innovative landfill bioreactors were also evaluated using a semi-mathematical calculation model for their investment, operation costs, land space requirement, liquid emission treatment costs and savings, gas generation, collection, utilization costs and benefits and greenhouse gas accounting and global warming avoidance. 

Useful and helpful for decision makers

Understanding of the innovative landfill bioreactors are useful and helpful for decision makers in East-African cities for making the choice of disposal of municipal solid waste.
