description: The magnitude of waste stream hasacquired some abrupt dimensions, with correspondingineffective and inadequate management strategies,including insufficient funding on the part of government.In a year,solid waste generation in Ethiopia is estimated 8.8 million tons. In kilinto condominium site waste collection method is poor, most of solid waste is packing by plastic and collect the nearby collection area on road and then, in minimum fifteen days had been leftover on the road.<br> Finally small enterprise and the city municipalities collect the waste to the municipal waste collection center. But some wastes left over on the road side because of collecton negligence.<br> The main objective of the research is to determine the calorific value for household solid waste and management from kilinto condominium site, and specificallyto determine the physical andchemical analysis of household solid waste.For this study,the methodology that follows was purposive sampling and stratified randomsampling in 12 blocks, from each block six house solid waste were collected and exipermental work was done according to the procedure ASTM. Sample collection and preparation, Household solid waste quantification, Physcal and chemical characteristics solid waste, determination of heating value of Household solid waste was determined ,Statistical analysis were done by ANOVAand Management options were developed according to the result obtained.<br> The per capital solid waste generation rate of households in the residentarea of kilinto was found to be 0.6 kg/cap/day for residential households investigated.It has beenrevealed that the largest constituent of residential solid wasteis food-waste be 57 % and followed by plastic bottles &amp; bags 23 %, papers and cardboards10 % and the remaining 6 % and 4 % aremetals and other wastes (i.e. Bones, Diapers, pieces of cloth, Ceramic and Demolishing wastes).<br> From the result of this survey it can be concludedthat, biodegradable solid waste constituted a lion share of the solid wastes generated in kilinto condominium in household level .From the result High heating values (HHV), solid waste energy that found from household solid waste sample was 3.77,<br> v<br> 9.87 and 3.38 MJ/KG of food, plastic and paper waste respectively.So from this comparison of energy value it’s better to conducted that conversion of solid waste generated in the resident site to fast pyrolysis system is important decision, in order to reduce the solid waste generated through the residence and to obtain a bio fuels of HHV in the combustion process.<br> The food waste of carbon nitrogen ratio was recorded 20.66, from investigation food wastewas made to conclude that have a good ratio of C: N, Therefore its compatable to be managed for the pourpose of composting (fertelization) to decompose easily organic waste<br> Finally, for further researchis recommended tofocus on how much yield of bio oils and bio char produced in acontrol parameters of fast pyrolysis reactor. And it is recommended that the application of combined methods of solid waste management options as a model of this resident site using data obtained from physical and chemical result.
