Potentials Of Household Organic Solid Waste For Urban Agriculture In Condominium Housing Area The Case Of Basha Wolde-chilot Condominium Addis Ababa

Open spaces near communal housing areas are among one of the urban agriculturalrncomponents for the urban environment, but the soil in these open spaces has been affectedrnby different types of waste. The purpose of this study is to evaluate the potential of organicrnsolid waste (OSW) on the households to restore the disturbed soil, contribute to urbanrnagriculture and provide recommendations to prevent environmental pollution caused byrnOSW. Like many developing countries, Addis Ababa generates a significant amount ofrnOSW with substantial contributions from households. The generated OSW, which is beingrnsent to the landfill sites have been burning the ground, unpleasant odors, environmentalrnpollution, groundwater pollution, vegetation damage, affect biodiversity (Justyna & Pitchayan,rn2016).rnCondominium housing in Addis Ababa consists a large number of households (depend onrnthe design starting from G+2 -G+12) with small plots that tend to generate a large amountrnof OSW. The “Basha Wolde-Chilot” condominium site that is chosen for this thesis for thernreason that it contains three types of Solid Waste Management (SWM) system (verticalrntrash Shute , free stand metal garbage, and Trash bag(madabria) at their home),rncondominiums that are the same typology, manageable block number, and near to thernRiverside. The survey was applied to ten building that is determined by Taro Yamane’srnsampling method. Before the survey, the researcher provided colored trash bagsrn(“madaberia”) for residents in organic,plastic and other types waste categories followedrnby an awareness session on waste separation. Afterward, the researcher conducted a fieldrninvestigation, on-site waste characterization and measured the waste at the block in tworndifferent collection days.rnAccording to “Basha Wolde-Chilot” waste characterization, the average waste consists ofrn84.1% organic, 3.4 % plastic and 12.5% other materials. From this figure, the mostrnsubstantial amount is organic solid waste that could be recycled and generate compost.rnThe“Basha Wolde-Chilot” site generates 87,048 kg of organic solid waste every year andrnsend it to the landfill that contributes to the pollution of the environment qualityrndeterioration, worsening of groundwater quality, poor air quality from emitted gases andrnnoxious odors, and worsening climate change impact. From this figure, we can understandrnthat by failing to process waste, the site loses 10,881 kg compost every year. But thisrn10,881kg compost has the potential of restoring the disturbed soil and providing fertilizerrnfor 28,307m2 vegetation production,5,348m2 for attractive, aromatic and medicinal plantrnand for than 200 tree and shrubs for the “Basha Wolde-Chilot” condominium siterncommunity.rnIn conclusion, if the organic solid waste gets separated at the source (providing garbagernShute), recycled, composted and merge to the condominiums green space, it will providernsignificant input for the environment as well as for the residents. The application ofrncompost may vary according to the users need
