2. Introduction
History:
It was in 1862 that Alexander Parkes
introduced the world’s first-ever man-made
plastic, at the London International
Exhibition. “Parkesine,” as it was called,
was marketed as an alternative to ivory and
horn that Parks discovered while trying to
develop a synthetic substitute for shellac for
waterproofing.
3. What is Plastic
Plastic is defined as a material that contains an essential ingredient
an organic substance of large molecular weight. It is also defined as
polymers of long carbon chains.
Plastic was discovered by famous German chemist Christian
Schonbein in 1846. Plastics were actually discovered accidentally.
Christian was experimenting in his kitchen and by accident, he spilt
a mixture of nitric acid and sulphuric acid. To mop that solution (a
mixture of nitric and sulphuric acid) he took a cloth and after moping
he kept it over the stove. After some time, the cloth disappeared an
from their plastic got its name.
The word, plastic, was derived from the
word ‘Plastikos’ meaning ‘to mould’ in Greek. Fossil fuels have
compounds containing hydrogen and carbon (hydrocarbon) which
act as building blocks for long polymer molecules. These building

5. Uses of Plastics
Plastic is used across almost every sector,
including to:
produce packaging,
in building and construction,
in textiles, consumer products,
industrial machinery.
transportation, electrical and electronics
And others
11. How Plastics create problems?
– Nearly half of all plastic products are discarded
after a single use and take up to 1000 years to
disintegrate. Larger items, such as plastic bags
and straws, can choke and starve marine life,
while smaller fragments (microplastics) can cause
liver, reproductive, and gastrointestinal damage in
animals.
– Plastic pollution is a huge problem—and it’s not
too late to fix it
12. Continue…..
Plastic sticks around in the environment
for ages, threatening wildlife and
spreading toxins. Plastic also contributes to
global warming. Almost all plastics are made
from chemicals that come from the
production of planet-warming fuels (gas, oil
and even coal).
Plastic takes more than 400 years to
degrade
18. Solution of Plastic Waste
Avoid to use plastic once
Stop buying water packed in plastic
Cook more.(avoid to buy foods in plastic)
Recycle
Support a bag tax or ban
Spread awareness
Teach in School
Put pressure on manufacturers.
Government Schemes
22. Conclusions
According to recent research 80% of human
beings found micro plastics in their blood
cells. Do you know, what does it mean?
Plastic was invented to make our life good
and to increase the lifestyle of human beings
but now it is becoming a course to us.
If we will follow the above discussed
solutions, we may save our life and could
save the Earth as Green Earth.
