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?

The site…

UPLB has a total of

14, 669.23 hectares of real

estate holdings

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)

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

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?

However, these collected landscape organic wastes are only

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.

Sometimes called tree

chipper is a machine

used for reducing wood

(generally tree limbs or

trunks) to chips.

are often portable, being

mounted on wheels on

frames suitable for

towing behind a truck or

van. (en.wikipedia.org/wiki/Wood_chipper)

WOOD CHIPPER

A heavy equipment used

to move aside or load

materials such as leaf

debris, wood chips into or

onto another type of

machinery like dump

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….

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….

Benefits of mulching with wood chips:

Reduces bruising of fallen fruit

under fruit trees

Increase earthworm population

resulting in better aeration
