Data on solid waste generation rates and waste composition are the basic information tornplan and implement solid waste management systems. Adama town, like any developingrncountry towns, has poor solid waste management. This is mainly because of lack ofrninformation on the generation rates of the waste. To fill the gap this survey has beenrnconducted. The objective of the study was therefore to identify the compositions ofrnhousehold’s waste and analyze its generation rate; and assess solid waste managementrnsystems of the town and suggest some waste management options.rnThe study was conducted on randomly selected 162 households, that are expected tornrepresent all categories of income levels (low, middle and high income levels) and from allrncorners of the town. Daily waste from those households was separated into its components;rnweight and volume of each component were recorded. This has been conducted for 7rnconsecutive days to have better average per day domestic waste generation rate.rnThe study showed that waste generation rate has direct relationship with family’s incomernlevel. This study finding showed that low, middle and high-income households generatern0.67kg/HH/day, 1.21kg/HH/day and 1.87kg/HH/day, respectively; and on average, arnhousehold generates 0.77kg/HH/day. Similarly a person from low, middle and high-incomernlevel generates 0.11kg/cap/day, 0.35 kg/cap/day and 0.57 kg/cap/day, respectively, and anrnaverage of 0.15kg/cap/day. Total household waste generation rate of Adama town isrn35.2tones in a day. The average family size of participating households is 5.7 persons.rnRegarding waste compositions, there are about 13 types of waste components that arernidentified from household wastes. Food waste has the largest proportion both in weight andrnvolume (47.26% by weight). Ash accounts 45.38% by weight next to food wastes inrnhousehold wastes. Putrescible wastes form 60.5% of the total waste, indicating thatrncompost formation can be one of the options to manage the waste.rnParticle sizes of wastes have been also assessed. More than 55% by weight of wastes has arnparticle size of 10 - 50mm. In addition, 37.7% is fine waste having particle size of less thanrnVIIIrn10mm. Laboratory analysis of this study indicated that food and yard wastes have highrnmoisture contents, and most of the wastes have high calorific values; in both cases, one canrnconclude that material and energy recovery is feasible.rnIn general, from the study results, large proportion of the generated wastes is eitherrncompostable or recyclable or energy can be reclaimed from it. Therefore, the municipalityrnhas to reduce a waste that goes to disposal site through composting, recycling and energyrnrecovery techniques.
