Absence or presence of limited data about the quantity and composition of solid waste is one ofrnthe reasons for poor solid waste management in Addis Ababa. Domestic soh a waste quantIty anarncomposition analysis is one of the fundamental inputs for planning solid waste managementrnservices as domestic solid waste has a major share in developing countries. Domestic solid wasternquantity and composition analysis study was conducted in Arada sub-city. It is one of the ten subcitiesrnof Addis Ababa. This study was done (i) to determine the domestic solid waste generationrnrates at the source of generation, (2) to decipher the chemical composition of solid wastes and (3)rnto determine the role of socio- economic levels in household wastes generation rate in Arada subrn- city, Addis Ababa, Ethiopia.rnTo determine the minimum number of households that should be analyzed and to obtain resultsrnwith reasonable accuracy, proportionality that derived from domestic waste, income variables andrnstandard deviation of the population determined from preliminary survey conducted in otherrnAfrican countries were used. After determining, the required number of households, socioeconomicrnand solid waste management system related problems, domestic solid waste datarncollection, sorting of solid wastes in to different components and sizes, and measurement wererncarried out in 197 randomly selected households for 8 consecutive days. Proximate and ultimaternanalysis was also carried out. The survey and collected data was analyzed using StatisticalrnPackage for Social Science 10 (SPSS 10) software.rnIn Arada sub â€¢ .city, there is a problem of solid waste collection and disposal systems. Communalrncontainers are very few, located inappropriate places, have insufficient capacity and emptiedrninfrequently.rnThe result showed that the weighted mean waste generation rate for Arada sub-city was 106 gmlrncapita! day. The waste generation rate measured in weight and in volume units was directlyrnrelated to household income. In all income groups, the food waste constitutes the highestrnproportion of the waste stream and its fraction is 59.2 %. Food and yard wastes have thernoptimum C-to-N ratio and moisture contents similar to the standard values of municipal solidwastes. Thus, they are suitable for composting. Food waste also has the highest caloric value andrnit is recommendable for energy recovery.rnFor a sustainable waste management, a great attention should be given to individuals as well asrnprivate organizations that are involved in material/energy recovery, recycling and compostingrnactivities. In addition to this, enough communal containers should be located in reasonablerndistance and their location should be done in conjunction with the residents and they should bernemptied frequently.rnEstimating the quantity and composition of household waste at the source of generation is veryrncrucial. However, there are some practical issues that should be considered during sampling tornimprove the accuracy and the relevance of the result.
