Abstract
In any solid waste management study information on solid waste characteristics and rate of
generation is essential. One of the main constraints for proper planning and design of solid waste
management in Addis Ababa is the absence of reliable and up to date study in this area. Since the
lion share of the municipal solid waste (76%) is contributed from residential houses giving
solution to this part will contribute much for the over all management of the municipality solid
waste.
The assessment of management options for domestic solid waste was done in an area called
French Legasion situated in Yeka sub-city, one of the 10 sub-cities of Addis Ababa city
government, with the objective of assessing the characteristics of solid waste generated at the
household level and its level of impact on the environment as well as identifying sustainable
management options accounting for economical, environmental feasibility and social attitudes.
To get reliable data 120 households were randomly selected from the study area. A structured
questionnaire was used to collect household level data on the socio-economic and daily traits.
The solid waste of each household was collected, sorted and weighted for 11 consecutive days for
compositional and generation rate analysis. The proximate and ultimate analysis was also
undertaken in the Addis Ababa chemical engineering laboratory and in the analytical laboratory
of ILRI. Statistical software called Statistical Package for Social Science (SPSS 10) was used
during the analysis for both the structured questionnaire and the collected solid waste data.
According to the data analysis the composition of the waste was found high in food waste
(55.35%) followed by ash and dirt (22.29%); the average generation rate was determined to be
196 gm/cap/day with the average density of 311 kg/m3. The correlation analysis clearly showed
that the generation rate positively correlated to the socio-economic background of the
households and negatively correlated to the educational background
