Solid Waste Generation Rate and Characterization Study for Laga Tafo Laga Dadi Town, Oromia, Ethiopia

Abstract

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.

Optimized landfill site selection for municipal solid waste by integrating GIS and multicriteria decision analysis (MCDA) technique, Hossana town, southern Ethiopia

“…3 ). However, the findings of this study was slightly higher than those obtained in other cities of the country such as Sawla 34.81 % [ 20 ], Debre Berhan 33 % [ 20 ], Wolkite 25.53 % [ 21 ], and lower than Laga Dadi 37.7 % [ 22 ] and Wolaita Sodo 59.5 % [ 23 ]. According to this study findings and other comparable studies conducted in urban developing countries, food waste has a large dominance of biodegradable solid waste because it is the most commonly used unprocessed food.…”

Evaluating Waste-to-Energy Technologies as a Waste Management Solution for Uganda

“…For example, a similar project like the Reppie plant in Ethiopia could be set up in Uganda to process waste to generate about 20 MW of electricity. Such a project is comparable because Ethiopia is reported to have waste compositions comprising of 60% organic waste [59,60] which is similar Uganda. Also, this plant has a pre-treatment section to increase the energy content in the waste.…”

The Impacts of Poor Solid Waste Management in Legetafo-Legedadi Town, Oromia, Ethiopia

“…It is located at altitude 2,316 to 2,500 masl. The mean annual, maximum, and minimum temperatures of the town are calculated to 17.22°C, 23.76°C & 10.67°C, respectively, which is the characteristic of a warm temperate climate [14]. Recently the town administration has four kebeles namely, LagaTafo (01) and LagaDadi (02), Dambel and Eka Sadden with in an area of 24,350 hectares.…”

“…From field observation in Legetafo-Legedadi, there was evidence that the Town still loses a significant amount of potentially valuable recourses and "secondary raw materials" such as metals, wood, glass, paper, and plastics which can be recycled or reused. Even though each household in the Town currently generates on average 156.95kg of waste every year [14], only 5% of this waste is reused or recycled, while waste can make a big contribution to economic growth and job creation. A study published by the EC in 2012 showed that full implementation of EU waste legislation saves€72 billion a year.…”
