Abstract: The basic foundation and the initial step of designing and developing an effective waste management system is implemented through quantification and characterization of the waste generated. To have accurate quantification and characterization, data such as the type of solid waste generated, its characteristics, composition, seasonal variations, and the source of the waste have to be assessed and gathered. The samples that had been studied were made to be very large to make the samples more representative. The sampling system employed in this study was stratified sampling technique. All educational centers (schools) were grouped to Primary schools, Secondary schools, and Colleges. Samples that represent the population were drawn from each group by simple randomization from each of the groups. Characterization of the waste for each sampled school was done manually by hand sorting. The result of the study showed that the total solid waste generated from schools in the sub city is 215Kg by weight and 2395.8lit.by volume per day respectively. The density of the waste was 89.5Kg/m3. The mean total solid waste generation rate of the schools is 2.6Kg by weight and 28889.63Cm3(28.9lit.). The physical composition analysis manifested that the composition of paper took the lion’s share of 85% by weight and 94.2% by volume respectively. The second was food waste which was 5.5% by weight and 4%by volume respectively. From the result of the study all of the schools reuse materials like wood and metal to maintain their blackboards, desks, etc. 83% of them burn their waste at the pre-prepared holes while 88% of them use to store and accumulate their waste temporarily with basket and open field before burning. Based on the findings of the study, the potential of recyclability of the waste from the schools is undoubtedly enormous. Therefore a city wide network of isolating and collecting the paper at the schools’ level is very essential. The bureau of Education should connect the schools with the recycling factories so that a better waste management is possible.
