1.0 INTRODUCTION
What is pollution? According to the Environmental Quality Act
1974 , any form of pollution is pollution that occurs either
directly or indirectly related to the properties of physics ,
chemistry and biology with the release , issue or placing the
waste until a negative impact on humans , plants and animals.
Environmental pollution can be defined as something natural
stain that can affect the earth's ecosystem. This
contamination from day to day growing and increasingly
alarming as more material is wasted intentionally or not made
by humans. The balance of nature is becoming increasingly
unstable due to various pollution occurs.
Plastic is one of the contributors to pollution. Plastics are
made of long polymer wherein each polymer constructed from
smaller units called monomers of different producing polymers
of different properties and characteristics. Plastic
classified according resin used in the manufacture and can be
classified in 7 groups such as:-
Group Description Example

1
Usually identified with PET, PETE or
Polyethylene Terephthalate. Commonly used
to make bottles and food containers. Not
suitable reused or stored for too long.
Chemical reactions are also easily occurs
if placed in outside weather conditions
at room temperature. Easily recognizable
because usually it will absorb the smell
and taste of a drink or food store
therein. This type of plastic can be
recycled and worth.
2
It uses material High - Density
Polyethylene or known as HDPE. HDPE is a
very safe product because it will not
give chemical reactions on the material
stored therein. Typically used for
containers for milk storage, lube oil,
shampoos and detergents. Most toys are
made of this material. It is also
suitable for recycling.Group Description Example
3
Plastic items from Polyvinyl Chloride or
PVC. PVC is used to make various types of
pipes and components of vehicles because
of its ruggedness. It is not suitable as
containers for food as toxic. It also can
be recycled.4 The main material is plastic Low- Density
4 PLASTIC POLLUTION | NORHASNANI BINTI MANAF SX130668KAWS07
Polyethylene or LDPE. It is most common
that we use all kinds of plastic bags as
well as a thin plastic wrapping, wrapping
and padding. All this is made of LDPE due
to its strong, elastic and flexible. It
can be recycled.
5
Plastic is very durable and resistant to
high temperatures. It is made of
Polypropylene or PP. It is usually made
Tupperware, bottle caps, cans and vehicle
components. It is the safest as
containers for food and beverages. Many
homes also external equipment using these
plastics. It can also be recycled.
6
Also known as the goods Polystyrene (PS)
or Styrofoam. Can be recycled, but very
difficult. It’s light and white but
fragile. Suitable for sound-absorbing
liner and yet most often used as a
disposable container for food. But it is
not suitable at temperatures hotter as
easily react and can lead to poisoning.
We recommend that you avoid using this
material with your food.7 It is classified to other types of
plastics that are not included in the
above classes. Polycarbonate material
usually is and polylactide. He included

in this category. Items usually were as
CD, digital goods component, the former
medication and baby bottles. It is hard
at recycling.

2.0 DEFINING PROBLEMS
Dumping of plastic occurs and cause pollution in terms of
pollution of soil, water, and air. Soil contamination occurs
when increased use of plastic pollution in terms of pollution
of soil, water, and air.
2.1 Soil Pollution
Picture 2.1.1 Soil Pollution
6 PLASTIC POLLUTION | NORHASNANI BINTI MANAF SX130668KAWS07
Soil contamination occurs when the plastic is not
biodegradable which causes soil layers cannot be penetrated by
plant roots and water does not flow until the water
infiltration and minerals that can fertilize the land lost and
the number of microorganisms in the soil would be reduced as a
result cannot be a source of food. Contamination of land means
a substance which has resulted in a land or region changes
colour, fertility and erosion. Soil contamination occurs due
to waste either in liquid or solid form. Pollutants are
composed of organic pollutants, chemical or physical. If an
area or land has lost its fertility, the land will be turned
into a blackish colour while, the vegetation in the area will
also wither away.
2.2 Air Pollution

Picture 2.2.1 Air Pollution
Meanwhile, air pollution occurs when plastic is burned will
emit harmful pollutants such as smoke, toxic and corrosive
gases such as sulphur dioxide pollutants that cause acid rain
and the greenhouse effect. Air pollution can be defined as the
availability of gas, liquid or particles contained and
suspended in the atmosphere until the occurrence of a change
and affect the lives or other materials. The materials are
suspended in the atmosphere and have a negative impact on
humans, plants and animals and the environment. This caused
the gas and contaminants will enter the human body through
breathing and the ability to block the flow of oxygen into the
blood vessels. This can cause a variety of diseases such as
cancer, asthma, cramps and anaemia. In addition, materials
such as dusts, mists, vapours or materials that can prevent
eye sight are also an example of a form of air pollution.

2.3 Water Pollution
Picture 2.3.1 Caused From Water Pollution
In addition, the plastic is also one of the causes of water
pollution which can affect aquatic life. Water pollution is
the change that happens to water in terms of content or colour
and chemical properties caused by various pollutants in
various forms such as solid, liquid and gas. This can be
proved when there are marine animals such as turtles, fish and
other animals that die after eating the suspected food grade
plastic. Plastic materials consumed by aquatic life cannot be
digested, causing death. Furthermore, odour and insect
contamination effects of uncontrolled dumping of plastic will
cause health problems to humans.

3.0 PROPOSED INNOVATION
Government and NGOs have implemented various campaigns to
reduce the use of plastic. Recycling of waste materials such
as plastic is one of the ways that have been implemented since
2000 in Malaysia. Furthermore, innovation in terms of
production of new materials such as bioplastic result from
agricultural waste plastic materials are also increasingly
replacing adopted by the public. Not only that, even the
government has entered into SATURDAY as a day without plastic
bags. Plastic bags be replaced with the box or bring your own
bags (cloth, paper) from home. In addition, the government
recently there was shouting campaign to bring lunch from home
to save money. This method can reduce the use of plastic food
packaging because people will use a closed container that can
be replicated to like tupperware. Lastly, Avoid the use of
plastic materials is also one way to reduce pollution of
plastic materials. Although it is known, the use of plastic
low cost compared to using other materials, but must also be
considered in terms of safety and human health. The method
replaces the plastic material to material made of wood
(natural), for example, can reduce the use of plastic.
3.1 Recycling
10 PLASTIC POLLUTION | NORHASNANI BINTI MANAF SX130668KAWS07
Recycling is the process of treating waste materials to
produce new goods. Recycling reduces waste, reducing the use
of new raw materials, reduce energy usage, reduce air
pollution (from incineration) and water pollution (from
landfill) and reduce greenhouse gas emissions compared to the
production of new goods from raw materials. Recycling can be
done either by reselling unused plastic or using creativity to
create new objects. For example, a bottle of mineral water can
be used as vases, and others. Returns in terms of money
obtained when the plastic is sold to a collector of recyclable
materials. In addition, the practice of recycling waste can
cultivate values in the individual, such as planting thrifty,
responsible and loving environment. In addition, we can save
natural resources depleting for plastic materials, we can not
only save resources to make plastics but we also can avoid the
worst effects of the chemicals they produce. Recycling
activities can also open another employment opportunities to
people in a recycling plant. Indirectly, this activity can
also reduce the rate of unemployment among people.

3.2 Biodegradable Bioplastic
Picture 3.2.1 Biodegradable container
Bioplastic is a plastic made from sources of renewable
biomass, such as fat and vegetable oil, corn starch, pea
starch, tapioca starch or microbiota. Bioplastics are more
sustainable because it can decompose in the environment faster
than regular plastic, which can take more than 100 years.
Biodegradable bioplastics designed either anaerobic or aerobic
environments, depending on how it is produced. A rigid clear
thermoplastic polymer of styrene that can be moulded into
objects or made into foam that is used as thermal insulation.
12 PLASTIC POLLUTION | NORHASNANI BINTI MANAF SX130668KAWS07
Polystyrene plastic consumption as food wrappers were
introduced for years. But, unknown to that of polystyrene
materials will cause adverse effects when exposed to heat as
polystyrene will issue a toxic substance (styrene made of
carcinogens) that can cause cancer in humans. Chemicals from
polystyrene containers will absorb into the food and then the
human body. Thus, a nanocomposite material known as a result
of agricultural wastes and crop commodities such as kenaf,
rice husks and cassava were introduced. Nanocomposite barrier
characteristics, high strength and very good thermal stability
as packaging materials. Ability to parse this product gives a
new perspective that can save the environment from plastic
pollution.
4.0 CONCLUSION
Uncontrolled use of plastic will cause pollution to the
environment as well as causing damage to natural resources.
Governments need to improve the implementation of laws to
control pollution caused by humans. Civic awareness about the
causes and effects of the use of plastic should also be
applied to the inside of each individual. Therefore, the
prevention of the use of plastics can reduce environmental
pollution is increasingly deepening day. In sum, refusal the
13 PLASTIC POLLUTION | NORHASNANI BINTI MANAF SX130668KAWS07
use of plastic materials because these measures can solve many
pollution problems, helping a comfortable life for the
universal creature, maintain environmental quality, and thus
help the country reduce the area of the landfill. Widespread
use of plastic materials will affect the environment, health,
safety and human life if not addressed in a controlled manner.
The encouragement of the creation of new materials that can
replace plastic material that does not affect natural
ecosystems greatly needed. This not only can save the
environment, but it also can save dwindling natural resources
from time to time.
