Litter Rating and The Engineering Solution For Bandar Seri Iskandar

This project presents the finding of a study on litter survey to measure the litter density
and litter rating in a randomly selected area in Bandar Seri Iskandar. The purposes of the
project are to identify the severity of litter problem in the town and to determine the
main compositions of the litter. Three main surveys conducted in this project were
survey along roadside, survey on open area and drainage litter survey. The result shows
that the level of litter problem in Bandar Seri Iskandar based on Litter Pollution Index
(LPI) as moderately to significantly polluted. The compositions of the litter also were
identified according to the categories based on usage. Litter survey along the roadside
found that the visible litter is only one sixth (1 :6) of the actual litter. Plastic bag
constitutes the highest percentage oflitter compositions with twenty-five percent (25%)
followed by food wrapper and paper with 24% and 14%, respectively. Litter survey on
open area proved the area without solid waste container has the higher amount of
collected litter. 42 litters per 100 m2 found in the area without solid waste container
while only 5 litters per 100 m2 collected from area provided with solid waste container.
Drainage survey highlighted the drains located near commercial area has high tendency
of litter accumulation. The possible causes and sources of the litter were identified based
on their categories. Solutions to the litter problem are recommended by three
approaches; engineering solution, management solution and educational solution.
Recommendation for improvement in term of carrying out the survey as well as
implementing the surveys is highlighted. The area of Seri Iskandar is concluded as
moderately polluted, and the main compositions of the litter are wrapper and plastic
packaging. The area of Bandar Seri Iskandar is concluded as moderately polluted with
litter mainly plastic packaging (25%) and wrapper (24%).
