Study of Domestic Solid Waste Management in Jimma Town, Southwest Ethiopia
2012
Improper solid waste management has become a major environmental problem in Jimma town. The town has been experiencing very poor solid waste management system. In-adequate solid waste management in the town has resulted in the accumulation of waste on open lands, in drains and in the residential areas, causing a nuisance and foul-smelling pools, environmental pollution through leachate from piles (water and soil pollution) and burning of waste (air pollution), clogging of drains. This study was, thus, conducted to fill the existing gap. The study was conducted on randomly selected 120 households that are estimated to represent all classes of income levels; low, middle and high. Daily waste generations from those households were collected and separated into its components; weight and volume of each component were recorded. This has been conducted for nine consecutive days to determine the average daily household waste generation rate and per capital daily generation rate. The study s...

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 socioeconomic 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.
Municipal solid waste generation and disposal in Robe town, Ethiopia
Journal of the Air & Waste Management Association, 2018
The amount of solid waste generated in developing countries is rising over time due to economic growth, change inconsumer behavior, and lifestyles of people. But it is hard to manage and handle the increase of solid waste with existing waste management infrastructure. Thus, the management system of solid waste is very poor and has become a serious problem. The main purpose of this study is to quantify the volume of solid waste generated and investigate factors affecting generation and disposal of wastes in the study area. The result of this study indicated that total waste generated from households was about 97.092 kg/day. Furthermore, the study reveals that the solid waste generation rate of the town is 0.261 kg/person/day. About 57.5% of solid waste is properly disposed of to a landfill site, whereas the remaining 42.5% is illegally dumped at the roadsides and open fields. Implications: Nowadays, in developing countries there is a high concentration of people in urban areas, causing the generation of an enormous concentration of municipal waste in urban areas. Therefore this study's findings will be important for various policymakers and town planners. This may also serve as a benchmark for the municipal authorities of the town for whom the problem is still invisible and negligible and can push environmental protection authorities to reexamine the implementation of their policies and strategies with regard to the broader issues of human and environmental health conditions of town dwellers.

The current rapid increase in population together with expansion of the town is producing large volumes of wastes, which demand greater infrastructure, institutional setup and community participation for its management. However, most of solid wastes that generated are remaining uncollected and simply dumped at open space. This study focused on identifying the types of solid wastes, waste generation rates, management practices and municipal solid waste management service of Chiro town. The results were based on the data collected from sample respondents that drawn from three kebeles of the town, proportional to total households through simple random sampling techniques. The result revealed that the types of wastes produced by sample respondents were organic matter, plastic, paper and clipboard, metal and others wastes (ash, leather and e-waste). The average solid waste generation rate of the town is 0.304 kg/capita/day. In the town there is no recognized prepared place either for the waste collection or for final disposal. The common disposal places used by the community were ditch (44.95%), local field (20.7%), road side (24.2%), farm land (3.5%) and burning-burying (4.5%). Yet around 2% of the respondents do not know where the wastes come out of their home finally disposed to as they deliver it by informal waste pickers. Therefore, its top priority to prepare the dumping sites and establish institutional setup for proper handling of the waste in the town.
Solid Waste Management Practices in Wayu Town, Jima Rare Woreda, Ethiopia
Solid waste management practices could be effective whenever it is described in terms of their sources, generation rate and their physical composition. The lack of timely information about the generation and composition of solid waste in Wayu town may be one factor for improper management of solid waste. As a result, this study was conducted to determine solid waste generation rate per household per day by weight and volume. Additionally, the nature of the solid waste composition was identified which helps in decision making and developing municipal solid waste management systems. The study used the already classified section of the town as ‘Got’ and the sample population is selected from each ‘Got’ by non-probability sampling. The household solid waste generation and composition data were collected and analyzed using excel program and questionnaire was summarized in charts, graphs and tables. Hand sorting was used for classifying the collected waste into the following thirteen fractions: paper, plastic, glass, metal, food waste, textiles, rubber, wood, dust and soil, ash, hair, bones and miscellaneous groups. The study result shows that in Wayu town the estimated household solid waste generation rate per household per day is 8.7 Kg and 0.29m3 by weight and volume respectively. And per day per household solid waste by density are 30kg/m3. The percentage composition of commercial solid waste fractions clearly shows that food waste takes the largest proportion of commercial solid waste and followed by ash, miscellaneous groups, wood, dust and soil, paper, bones, textile, plastic, glass, hair and metal waste by weight. The result shows, if composting and recycling are exercised in the town there is a possibility to reduce the amount of household solid waste going to be disposed illegally by 82.6% and 35.4%. Thus based on the generation rate and composition of solid wastes in study area integrated solid waste management system which combines a range of solid waste treatment options like source reduction, composting and recycling could be applied.

As one of cities in the developing countries, a rapid population growth and industrial activities pose many environmental challenges for Jimma city, Ethiopia. One aspect of urban growth posing a threat on sustainable development is poor solid waste management, which results in environmental pollution. The purpose of this study is to evaluate the quantity, composition, sources of waste generated, their current disposal practices, and to recommend appropriate management technologies. The total waste generated daily in Jimma city was ca. 88,000 kg, and the average per capita generation rate was 0.55±0.17 kg/capita/day. Eighty-seven percent of the waste was produced by households and 13% by institutions, and a negligible fraction (0.1%) was generated by street sweepings. During the rainy season, 40% more waste was generated than in the dry season because of the increased availability of agricultural food product. Further analysis showed that biodegradable organic waste constitutes 54% by weight with an average moisture content of 60% that falls within the required limits for composting. The nonbiodegradable components constitute 46% of which 30% of it was nonrecyclable material. Only 25% of the community uses municipal containers for disposal at the selected landfill site. Fifty-one percent of the households disposed their waste in individually chosen spots, whereas 22% burned their waste. Finally 2% of households use private waste collectors. The socioeconomic analysis showed that higher family income and educational status is associated more with private or municipal waste collection and less with the application of backyard or open dumping. These insights into generated waste and management practice in Jimma city allow making suggestions for improved collection, treatment, and disposal methods. A primary conclusion is that the biodegradable waste is a major fraction having suitable properties for recycling. As such an economic benefit can be obtained from this waste while avoiding the need for disposal.
Sekondi-Takoradi Metropolis, one of the rapidly expanding cities of Ghana has been facing serious problems with solid waste management. This is mainly due to the lack of available information about the types and quantity of solid waste generation in the area. Hence, the objective of this study was to determine the rate of household solid waste generation and its composition in the aforesaid city. The methodology and procedures for this study were derived from the Standard Test Method for Determination of the Composition of Unprocessed MSW (ASTM D 5231-92). All samples were hand sorted into 6 waste categories (paper, plastic, organics, metals, glass, and other waste). The study revealed that by weight, organic wastes constitutes the largest proportion of household solid waste (38%) followed by 19% plastics, 7% papers, 4% metals, 4% glass and 28% other wastes (comprising of sand, stones, ash, inert substances). The rate of daily waste generation per capita in the low, middle and high income households were 0.27±0.19, 0.4±0.19 and 0.58±0.24 kg/cap/day, respectively. The study revealed that there is no waste treatment or recovery facility established within the metropolis hence no significant waste recovery and reuse activities exist. The study showed that more than 38 % of the waste generated in Sekondi-Takoradi Metropolis is decomposable organic matter that can be re-used through composting as well as 34% of the waste having recycling potential thereby considerably mitigating the solid waste problem.
