Abstract
Data on solid waste generation rates and waste composition are the basic information to plan and implement solid waste management systems. Households of Woreda three in Lideta sub-city like other developing country towns have poor solid waste management. Hence this study has been conducted to investigate the generation rate, physical composition of Households solid waste and the attitude of the households towards solid waste management practices. The study was conducted from December 01/ 2009 to December 21/2009 E.C on randomly selected 81 households, which are expected to represent all categories of income levels (Low, middle and high income levels) of woreda three in the sub-city. The weight of daily wastes generated from those sampled households was measured and then sorted in to its components and the weight of each component was also recorded using materials like: Balance scale, hand protective plastic gloves, mouth & nose mask, Plastic bags and plastic sheets. Questioners were also distributed among the household for assessing demographic and Socio Economic Characteristics of Respondents. The findings of this study showed that averagely low, middle and high socio-economic level households generate 0.95kg/HH/day,1.18kg/HH/day and 1.44kg/HH/day of Solid waste respectively. The statistical analyses indicate a significant difference in average quantity of solid waste generated per the three socio-economic levels of households (p<0.01).Results of analysis of waste compositions also showed that high contents of organic waste (64%) followed by Recyclable waste (18%) and Combustible waste (12%) was generated. The survey analysis also showed that illegal solid waste disposal in open spaces is common practice in the study area and some of the main reasons raised by the respondents were the inappropriate placement and insufficient number of communal containers. Therefore, based on the generation rate and composition of solid wastes investigated in Woreda three of Lideta sub-city, there should be integrated solid waste management system which combines a range of solid waste treatment options because of large proportion of the generated wastes is either compostable or recyclable.
