Abstract
The success of waste management requires reliable data on waste generation and composition,
which is critical for making decisions about the best waste management system. There is
currently no data on Municipal Solid Waste (MSW) generation and composition collected in
Bishoftu town. In order to provide baseline data for the establishment of a municipal solid waste
management system, the primary goal of this study is to analyse the rate of generation and
composition of municipal solid waste. The samples were collected from the household from 4
Keble’s and from different commercial activities like hotels, resorts, restaurants and cafeterias,
open market, super market and mini markets found in the town. The collected sample was sorted
out in to various components. Subsequently, the weight of each component were measured and
recorded. The daily generation of MSW works out to be 0.31 Kg /day/person with a density of
306 Kg/m3.The study results reveal that the MSW stream has the largest proportion of
biodegradable waste (69 %) followed by other waste (18 %) containing ash material and
different solid waste types. From the socio-economic analysis, middle socioeconomic group and
lower socioeconomic group generate more waste due to more family members and energy type
used for cooking while socioeconomic characteristics like education level, occupation, age,
gender, and housing condition have no relationship with solid waste management practices.
Understanding the movement of waste in an urban area is crucial for identifying the main
problems and opportunities for improvement in the efficient handling of waste. Assessment
instruments like material flow analysis (MFA), a technique that is widely used in waste
management research, offer an organized and objective assessment procedure to best describe
the waste management system, identify its strengths and weaknesses, and suggest feasible
alternatives. In order to assess the current waste management strategy used by the City of
Bishoftu, this study uses material flow analysis. Due to the waste's high organic content If waste
management options such as composting and recycling are implemented in the future, there is a
greater possibility of reducing the amount of waste stream that is disposed of in landfills as well
as lowering greenhouse gas emissions, which is a current global issue. By composting 50 % of
the waste designated to the disposal site 47.9 % of resource is managed which have an
increment of 78.1 % than the current SWM practice and a total reduction of 35.35 % in GHG
emission.
