4 Result and Discussion
4.1 Landscape Waste Management
Figures 4 and 5 show the average of two daily trips of landscape waste collected by the
contractor. There are seven zones requiring two trips of landscape waste collection
while four zones- 3, 8, 9, and 10—require only one trip of landscape wastes collection
daily. The first trip of the collection of dry leaves shows that the highest percentage
belongs to zone 8 with 93% and the lower percentage of dry leaves collection is zone
2 with 58%. Next composition of landscape wastes is twigs. The highest percentage
which is 29% belongs to zone 1, while the lowest percentage of twigs are zones 8,
9, and 11 with 8% of wastes. For branches, zone 7 shows the highest percentage
(11.4%) compared to other zones and the lowest percentage of branches collected
is zone 6 with 6.4%. Palm frond with 43% in zone 11 is the highest percentage
compared to other zones and the lower percentage in zone 8 with 6% of palm frond
waste collection. The last composition in landscape wastes is wood. The highest
percentage of waste collection is zone 2 with 12% of wood and the lowest is zone 4
with 2% of wood.
The second trip is performed only on seven zones. This is because the landscape
wastes for zones 3, 8, 9, and 10 are already all collected on the first trip. In this
trip, zone 4 shows the highest percentage collection of dry leaves with 98% of the
collection while zone 2 is the lowest with 55% of the collection of dry leaves. For
twigs, the highest percentage collection belongs to zone 7 with 20% and zone 11
has the lowest collection with 5% only. Next landscape wastes composition is the
branches. This landscape waste composition will be compared among five zones
only which are zone 1, 2, 4, 5, and 6. Zone 6 shows the highest percentage (15%)
among all zones and zone 1 shows the lowest collection with 0.9% compared to other
zones. For palm frond, the difference in collection amount among zones is small.
