Knowledge of the quantities and composition of the municipal solid waste is fundamental for the planning and development of waste management systems for cities. The objective of this study was to determine the composition and generation rate of household, commercial firms, government institutions and health care facilities solid waste in Laga Tafo Laga Dadi town, Oromia, Ethiopia. Representative Samples were randomly selected from all studied units for the solid waste generation rate per capita and composition determination. Formal survey using structured questionnaire was conducted to gather data on socio-economic condition and current waste management practices of the inhabitants. The per capita daily solid waste generation for household range 0.43 -0.46 kg and hotels, other business sectors and institutions were found to be 1.81, 1.57, and 0.41% kg/capita/day, respectively. The per capita daily solid waste generation in health facilities was found to be 9.61 kg/fac/day. The survey indicated that the household solid waste is composed of organic biodegradable 76% (food 62%) and ash 5% of the total weight of the sorted waste. Moreover recyclables constituents of the solid waste shared about 14.75% of the total weight. The Ropack residential village solid waste was composed of 48.66% organic (37.69% food) and bone accounts for 37.69% which equal to food waste. The recyclable and miscellaneous wastes account 13.94% and 2.76%, respectively. The organic waste of hotels accounts 67.45% (48.10% food) and the recyclables waste 2.44%. Likewise the ash was about 11%. Other business entities accounted 81.68% (68.81% food waste), recyclable shared 23.17% and the ash was 2.68% with miscellaneous 3.51%. The study also indicated that 37.72% infectious, 23.68% Sharps and 38.61% non-hazardous constituents of solid waste generated by the health care facilities in the town. From the result of this survey it can be concluded that, biodegradable solid waste constituted a lion share of the solid wastes generated in the town. Thus, the municipality can recover this waste by introducing an integrated urban agriculture that might convert this waste to organic fertilizer through composting.
