| 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. |
