3. Organic waste is anything that comes from
plants or animals that is biodegradable.
Includes landscape and pruning waste (e.g.
grass clippings, pruned branches and
removed/fallen trees)
What is landscape organic waste?

4. The site…
UPLB has a total of
14, 669.23 hectares of real
estate holdings

5. An academic campus that is naturally endowed with
numerous types of vegetations providing a beautiful,
cool ambiance and making it an environment-friendly
campus.
Vegetations are considered an important element in the
landscape of the university contributing to its majestic
and serene look.
large amount of landscape organic wastes (LOW) are
produce due to various operations required to
maintain its vast forested and verdant landscape
The site…
University of the Philippines at Los Baños (UPLB)

6. majority of the landscape wastes collected are
just thrown or compiled in any available open
area in the campus and are left to just
decompose on its own and worse, the
materials are burned as the only way of
disposing the collected organic waste.
The problem

7. With that practice, its potential for other uses is
set aside.
The problem
explore ways on how
leaves, grass clippings,
pruned branches and
removed trees can keep
contributing to
environmental quality
instead of burdening the
community as waste.
What are we
supposed to do?

8.  To showcase some specialized
equipment for efficient collection
and handling of landscape organic
wastes.
 To demonstrate the proposed
landscape organic wastes
management in UPLB campus
 To assess potential uses of
landscape organic wastes
collected within the campus.

trunks) to chips.

27. Benefits of mulching with wood chips:
Saves Labor – no weeding, less
time watering
Saves Water – far less watering
needed, and more rain absorption
Safer – no need for chemical weed
killers or herbicides
Stimulates growth – mulched trees
grow faster than unmulched trees
Makes trees more resistant to
disease and insects
Why do we need to do it….

28. Benefits of mulching with wood chips:
Keeps soil and roots from
overheating in hot summers
Eliminates injury to trunk from
mower collisions
Reduces soil compaction over roots
and adds loft
Nourishes the soil by adding
nutrients as it decomposes
Eliminates the need for tilling and
resultant root injury
Why do we need to do it….

29. Benefits of mulching with wood chips:
Reduces bruising of fallen fruit
under fruit trees
Increase earthworm population
resulting in better aeration
