|Abstract: ||Solid waste, which is a consequence of day-to-day activity of human kind, needs to be
managed properly. Addis Ababa like other cities in developing countries, faces problems
associated with poorly managed waste collection operation. This thesis deals with the city’s
current solid waste management problems, collection and disposal.
The city’s refuse collection operation is modeled using queuing/simulation model.
Spreadsheet Monte Carlo simulation technique is used to simulate the collection activities of
the vehicles. In a similar manner, the average waite time of the customer( unit volume of
waste) is also simulated. The result obtained shows that the collection operation is affected by
the relative location of zonal centroid with reference Repi landfill site. Based on the
simulation result, vehicle performance in collection operation is also evaluated. The number of
vehicles that are required to carry out the operation has been calculated.
In regard to solid waste disposal, alternative models are evaluated to meet the city’s disposal
need. Land filling with other disposal options is found to be better alternative. The four
proposed landfill sites are modeled using linear programming technique for optimized
collection/disposal operation. Energy recovery potentials of various disposal options like
landfill, incineration and anaerobic digestion have been assessed. Material recovery potential
of the city’s refuse is also evaluated for reprocessing. Better solid waste management option is
