Abstract:
Solid waste management practices could be effective whenever it is described in terms of their
sources, generation rate and their 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 purposive sampling. The
household sol�d waste generation and composition data were collected and analyzed using
SPSS20 Software and questionnaire was summarized in charts, graphs and tables. Hand sorting
was used for classifying the collected waste into 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 daj, is 1.23Kg and 0.04Jm
3
by weight and volume respectively. And per day per
household solid waste by density are 30kg/m
3.
The percentage composition of household solid
waste fractions clearly shows that food waste takes the largest proportion and followed by ash,
I
wood, bones, textiie, miscellaneous groups, dust and soil, paper, plastic, hair, rubber, metal and
glass waste by weight; moreover, plastic was ranked first by volume. The result shows, 89% and
68% by weight and volumes respectively are compostable. Moreover, 15% and 48% by weigh
and volume; 44% and 7 3% by weight and volumes are recyclable and combustible respectively.
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.
