
Recycle of solid waste is reduce the amount
of waste introduce to the environment.
also reduce the use of primary
commodities or raw material
Recycle paper would reduce 60% of water
usage, save 70% of the energy and reduce
the emission of the pollutants as much as
50 %


Recycle glass would reduce the usage of
water by 50%, 79% of the mining waste
could be avoided and air pollution could be
reduce by 14%
Recycle plastic reduce 30% of energy to
make polystyrene foam products compare
with the energy used for paper cups made
Lack of space

Not wise to build one landfill after another

Pollution, hygiene and other issues must be
consider
Water pollution

Most land areas are catchment area

Toxic leachate will pollute the water
Air pollution

Decomposition releases gas

Pollute air and contribute to global warming

Create unpleasant environment
Save energy

One aluminum can save enough energy to keep
a TV set on

One glass bottle can saves 100 watts
Compromising health

Air and water pollution

Live close with landfill

Vector may carry diseases


Cut down the need for disposal capacity
Lower emission from landfill, incinerators
and litter

Reduce of energy usage and emission

Lessen impacts and conserve raw material

The energy recovery will increase due to;


Reduction in energy use and related emission
and reduction in extraction and manufacturing
process
Long term, value of conservation materials

Protecting Our Planet
Global warming is
no longer a theory it
has sadly become a
fact.
The change needed
must be in your
actions today in
order to ensure a
bright (not too hot)
tomorrow.
•If greenhouse gas
concentrations keep
rising, climatic changes
are likely to result.
•Effects will be on the
environment and socioeconomic and related
sectors, such as health,
agriculture, forests,
water resources, coastal
areas and biodiversity.

Human activities are causing greenhouse
gas levels in the atmosphere to increase.
This graphic explains how solar energy is
absorbed by the earth's surface, causing
the earth to warm and to emit infrared
radiation.
The greenhouse gases then trap the
infrared radiation, thus warming the
atmosphere.



The definition of waste is varies among the
different nation
Lack of incentives among developing
countries for technology development
There are no fix price for the recycle
product and the erratic price fluctuations
favour incineration or landfill



Usually curb side collection is preferred
when recycle is higher. The “bring” system
is not conducive to participants
There no incentive for recycle in many
South East Asia countries
Frequent recycle causes contamination risk
due to heavy metal accumulation.




Recycle was introduced in PJ in 1991. In 1996,
yellow box recycling programme was launched
In KL plastic is the main material recycled
followed by metals. However, less then 1% is
recycle.
The awareness is high among Malaysian but
very few actually practice
Only 30 to 40% of paper is recycle compare with
US 50% and some European nation 60 to 70%




The important elements of integrated solid
waste management are not officially and
legally incorporated into the Malaysian
waste management practice
Organized source reduction and recycle are
lacking although a few NGOs do carry out
recycle activities
Only < 5% of the garbage is recycle and the
target should be 25 to 30%
Recycle of paper is currently practiced in
Malaysia especially KL, Penang and Ipoh


Among Asian countries, Australia, Japan
and India have a high recover (60 to 80%)
Which increase commitment in certain

Paper

The principal types of waste paper that are
recycled are old newspaper, cardboard, high
grade paper and mix paper

Except tissue paper, carbon paper, aluminum
foil/wax paper, plastic liminated paper and
contaminated paper
Glass

Container glass (for food packing), flat glass
(window glass), pressed or amber glass

Except crystal, mirror, window panes vehicle
screen, porcelain, ceramic, bulb, laboratory
apparatus and toxic container

Glass, to be reprocessed is often separated by
color into categories of clear, green and amber

Aluminum

Aluminum recycle is made up of two sector:
aluminum cans and secondary aluminum

Secondary aluminum includes window
frame,sliding and gutter

Except paint container, toxic container and
solvent container

The demand for recycled aluminum cans is high.
It take 95% less energy to produce an aluminum
cans from an existing cans than from ore
Plastic

Classified into two categories:
Clean commercial grade scrap
Post consumer scrap

Two type of post consumer plastic that most
commonly recycle are:
 polyethylene terephtalate (PETE/1)
High density polyethyelene (HDPE)
RECYCLABLES
Ferrous metal (iron & steel)

Traditionally come from large item such as cars
and appliances

Many communities have large scrap metal piles
at the local landfill or transfer station

In many cases, the pile are unorganized in
different metal are mix together – making them
unattractive to scrap buyer

Steel can use as food container (juice, soft
drink and food) and easily separated from
mixed recyclable or municipal waste.
Non-ferrous metals

Recyclable non-ferrous metal from
household items:


Outdoor furniture, kitchen cookware and
appliance, ladder, tool and hardware
From construction and demolition project:

Cooper wire, pipe, and plumbing supplies, light
fixture, aluminum siding, gutters.



From large consumer, commercial and
industrial products:
Appliance, automobiles, boats aircraft and
machinery
Virtually all nonferrous metal can be
recycled if they are sorted and free of foreign
materials such as plastic, fabrics and rubber
•Recycling soap bars from the guest rooms
•Re-use plastic bottles whenever possible
•Printing is highly discouraged unless absolutely necessary.
•Replacing bottled water with water
dispensers for meetings and events thus
reducing 43,200 plastic bottles per year.
•SGHKL associates are given a Hijau Way
Canvas to discourage use of plastic bags.
•Changing of plastic laundry bag to nonwoven bag.
•Separating of glass, paper, aluminum cans and plastic for
collection by relevant parties.
Funds received from this exercise are channeled to the sports
and welfare funds.



The methods used for the collection of
recycle materials includes curbside collection
and delivery by homeowner to drop-off and
buy-back centres
The future separation and processing of
waste that have been source-separation is at
Material Recover Facilities (MRFs) or
Integrated Material Recover
Facilities/transfer facilities (MRTFs)



Required residents or businesses to separate
recyclable materials at the source and bring
to a specified drop-off or collection centre
Require residents to store the materials until
sufficient and material is collected to the
drop-off centre.
The storage of multiple material types is a
problem in densely populated area.


To encourage participation, most successful
programs have made drop-off centres has
convenient as possible
Other incentives, such as donating portions
of proceeds a local charity
Buy-Back Centres

Refers to a drop-off program that provides
monetary incentive to participate

The residents are paid for their recyclable either
directly or indirectly through reduction in
monthly collection and disposal fees.


Separation is a necessary operation in the
recovery of reusable and recyclable
materials from MSW
Separation can be accomplished either at
the source of generation or at MRFs /
MRTFs.
Integrated MRTFs

The function of a drop-off centre for separation
waste.

The facilities include:
Material separation facilities
A facility for the composting and
bioconversion of waste
A facility for the production of refusederive fuel
Transfer facility




Chemical and biological processes are use
to reduce the volume and weight and to
recover conversion products and energy
The most common used chemical
transformation process is combustion.
Used in conjunction with the recovery of
energy.
The most commonly used biological
transformation process is aerobic
composting
If you do care, start recycle
