2. Introduction…
Plastics is the general common term for a wide range
of synthetic or semi synthetic organic solid materials
suitable for the manufacture of industrial products.
Plastics are typically polymers of high molecular
weight, and may contain other substances to improve
performance and/or reduce costs.
Plastics is one of the few new chemical materials
which pose environmental problem Polyethylene,
Polyvinyl chloride, Polysterine is largely used in the
manufacture of plastics

3. Plastics
Plastic is a long, chain like molecules (polymers) made
from petroleum capable being molded, extruded or
cast into various shapes.
The first plastic was invented in 1862 by Alexander
Parkes.
At first plastics could only be made in brown or black
(Bakelite) color.
In 1930’s, ‘Amino Plastics’ had been invented which
could be made in lots of bright colours.

4. Origin of plastics
Most of the plastics are made from three raw materials

7. Plastics are made from fossil fuels.
Fossil fuels contain hydrocarbons, which provide
small building blocks called monomer
These hydrocarbon monomers are link together
to form long carbon chains called polymers.
The process of forming long molecules is called
polymerization.
The polymerization form viscous, sticky
substances known as resins, which are used to
make plastic products.
For e.g. ethylene is a gaseous hydrocarbon.
When it is subjected to heat, pressure and certain
catalysts, the ethylene molecules join together
into long, repeating carbon chains.
These joined molecules form a plastic resin
known as polyethylene. A Vishvaniketan Vidyavihar Initiative

8. Properties of Plastics
Plastics are strong, light weight, flexible and durable.
Plastics show superior optical properties (Clarity, gloss and
color)
Plastics can be easily moulded into a variety of shapes and
sizes.
Plastics have excellent mechanical strength (tensile
properties, tear resistance and impact resistance)
Plastics are relatively cheap compared to tin, glass and
steel.
Plastics are reusable and recyclable.
Plastics have long use life.

10. Positive aspects of plastics
Plastics are good electrical / heat insulators.
Plastics do not corrode or decay.
Plastics are cheap and dispensable.
Plastics are resistant to chemicals, water or grease.
A Vishvaniketan Vidyavihar Initiative
11. Negative aspects of plastics
Plastics can either be non-biodegradable or degrade
very slowly.
Plastics are flammable and release toxic fumes when
burned.
Plastics can contaminate foods with dangerous
chemical compounds.
Plastics usually have low melting points and therefore
expand with heat.
A Vishvaniketan Vidyavihar Initiative
12. Plastic Pollution
Plastic is one of the new chemical
materials which pose
environmental problem.
Plastic in the environment is
regarded to be more an aesthetic
nuisance than a hazard, since the
material is biologically quite inert.
Plastic is cheap, it gets discarded
easily, and its persistence in the
environment can do great harm.
A Vishvaniketan Vidyavihar Initiative
13. Negative impact of plastic
production
Plastic resins are made by using non-renewable
natural resources.
Approximately 8% of world’s oil production is used to
make plastics.
Over exploitation results in depletion of natural
resources.
A Vishvaniketan Vidyavihar Initiative
14. Negative impact of plastic on land
Plastic pollution on land is both physical and chemical.
Plastic reduces soil fertility by forming the part of manure
for years.
Plastic spoils environmental aesthetics and hygiene
Plastics in landfills emit hazardous VOCs during
incineration.
Plastics in soil can lessen the growth of plants and trees by
blocking the absorption of minerals, water and other
nutrients.
Plastics can cause land slides.
A Vishvaniketan Vidyavihar Initiative
15. Negative impact of plastic on Air
Industries emit large amounts of carbon monoxide,
dioxin, and hydrogen cyanide
These gaseous pollutants contaminate are and cause
respiratory diseases, nervous system disorders and
immune suppression in human beings.
A Vishvaniketan Vidyavihar Initiative
16. Negative impact of plastic
on Fresh Water
Plastics wastes dumped in water courses contaminate
and poisons freshwater life.
On leaching in water, plastic can easily enter the
human food chain and harm human health.
Plastic debrises clog the sewage drains and create
stagnant water which will be an ideal habitat for
mosquitoes and other parasites.
Chocked drains cause flooding during monsoons.
A Vishvaniketan Vidyavihar Initiative
17. Negative impact of plastic
on Marine Environment
Effects of Plastics on marine life include
the entanglement and ingestion of
plastic debris by marine vertebrate.
Over a million sea birds and mammals
die annually from ingestion of Plastics.
Plastic is mistaken for flood and is eaten
by birds, turtles, seals, and whales. This
may choke them, poison them or
impede digestion and causing
starvation.
A Vishvaniketan Vidyavihar Initiative
18. Cont….
Marine turtles become entangled in
discarded nets and were found dead
with plastic garbage bags in the
stomach.
Some marine mammals swallow
plastic bags, which resemble jelly fish
in sea water.
About 44% of sea birds eat plastics
mistaken for food leading to
suffocation or blockage of digestive
tracts and eventually death.
A Vishvaniketan Vidyavihar Initiative
19. Negative impact of plastic
on human health
Toxic chemicals contained in plastics cause
neurological problems, cancer, birth defects, hormonal
changes gastric ulcer, thyroid problems and
cardiovascular disease.
The endocrine disrupting chemicals in Plastics have
been contributing to obesity and diabetes.
The plastic bottles may leach cancer-causing chemicals
such as phthalates (a component makes plastic pliable)
and Bis-phenol A (a component harden plastic), which
is a synthetic estrogen, can affect the hearts of women
and can permanently damage DNA of mice.

We will distribute paper bags, which will be making by
our students from Newspaper (Reuse of newspapers).
The training of ‘paper bags making’ will be provided by
Govt Spine Institute. More over, we are purchasing
paper carry bags from them. This money will be using
to develop the career of those patients who are
paralyzed.
We are conducting the seminar for our school students
in school campus to bring awareness to change the
habits for ‘green revolution’.
