In Addis Ababa as in many cites in developing countries waste generation has been increased,rnboth solid and liquid, as a result of the rapid rate of urbanisation. From the total solid waste,rnmore than 50% are decomposable organic. Hence the objective of this research is mainlyrnemphasizing on the use of compo sting urban organic waste and its implication on sustainablernsolid waste management in Addis Ababa.rnIn order to achieve the objective of the study, case study with in-depth interview, focus grouprndiscussion and direct observation has been administered. Further more to know there is a linkagernbetween compo sting and urban agriculture, the researcher purposefully took five cooperativesrnand distributed 30 questionnaires (six from each).rnThe waste analysis of Addis Ababa showed that the percentage of organic waste in the MSW isrnquite high. According to the finding, the processing of these organics can deliver importantrnenvironmental benefits, including the recovery and conservation of resources and a reduction inrnthe quantity of organics going to landfills. The finding further indicate that diverting hugernamount of solid from landfill reduce the environmental impact of the remaining waste byrnreducing methane production. Further more the analysis showed that the nutrient content ofrncompost is much better to the growth of plant than artificial fertilizer. In addition to the abovernfinding, the study also explains that composting urban organic waste can create employment andrneventually generate income particularly fore those urban poor.rnUnfortunately the finding indicated that in order to sustain the project both composting site usernman made technology which create problem on the employee and the environment.
