The document discusses the extensive use and contribution of plastics in various fields, highlighting their benefits such as durability and low cost, as well as the environmental concerns related to plastic waste and contamination in marine environments. It emphasizes the importance of effective waste management strategies, including recycling and new technologies like plasma pyrolysis, to address plastic pollution. Furthermore, the document calls for education and implementation of schemes to mitigate the impacts of plastic waste globally.

2. *INTRODUCTION

3. Plastics have made significant contribution in almost every field
of human activity today –
* agriculture,
* medical,
* Transportation,
* piping,
* electrical and heat insulation,
* packaging,
* Manufacturing of household and electronic goods,
furniture and other items of daily or specific use.

4. *
Plastics are widely used because of their light weight nature,
durability, potential for diverse applications, and low price.
i. hygienic – inert and chemical resistance,
ii. Light weight and non-breakability,
iii. Excellent barrier properties - enhancing shelf-life,
iv. Superior impact resistance,
v. Sterilizable and resistance to bacterial and other microbial
Growth,
vi. Transparency as well as opacity.

5. *
A. RECYCLABLE PLASTICS
(Thermoplastics):
PET, HDPE, PVC, LDPE, PP,
PS, etc.
A. NON-RECYCLABLE
PLASTICS
(Thermoset&others):
Multilayer & Laminated
Plastics, PUF, Bakelite,
Polycarbonate, Melamine, Nylon
etc.

6. *CONTAMINATION OF
MARINE ENVIRONMENT
BY PLASTIC DEBRIS

7. *
MICRO PLASTICS (1 to<5 mm)
MESO PLASTICS (2–20 mm)
MACROPLASTICS (≥25 mm).
EFFECTS:
These plastics has the potential
to harm fish and other wildlife in
ocean by entangling and plastics
being eaten by creatures.
In a 2006 report known as
plastic debris in the world’s
oceans, it was estimated 267
animal species suffered.

The process of road lying using
waste plastics is designed and
the technique is being
implemented successfully for
the construction of flexible
roads at various places in India.
Plastic waste collection,
segregation & storage
Cleaning & drying of
Plastic waste .
Shredding plastic waste into
required size (2 to 4 mm).
Stone aggregate
(granite,ceramic) heated
around 160°C-170°C.
The coated aggregate is mixed
with hot bitumen at temperature
ranges from 155°C-163°C.

11. *
Waste material such as
plastic waste used for co-
processing.
Cement producers or
power plants can save
fossil fuel and raw
material consumption,
contributing more eco-
efficient production.

12. * Plasma Pyrolysis is a
technology, which put
together the thermo-chemical
properties of plasma with the
pyrolysis process.
*The extreme and versatile
heat generation ability of
plasma pyrolysis technology
enables it to dispose of all
types of plastic waste.
*It can accept a broad range
of plastics, including those
that are unwashed,
unsorted, or which are
hard to recycle.
*The fuel oil and diesel are
condensed from a gaseous
state into a liquid state,
which are collected as the
process continues.

13. *BIODEGRADABLE
PLASTICS
*PHV
*PHB
*PLA

14. BIO-BASED POLYMERS:
 It uses a renewable carbon
source instead of traditional
plastics that source carbon
from fossil fuels.
One of the Bio plastics are
made from PolyLactic
Acid(PLA). It is made using
dextrose from corn.
But these plastics when
degrade will lead to
evolution of methane gas
which is a greenhouse
gas causes global
warming.

15. * Recycling ensure that the unwanted and
discarded plastics waste does not remain in road
side nor it is carried to the landfill.
* So Better the reduction of plastics should be
done.

16. *
*Recycling of waste plastics is an efficient way to improve
the environmental problems.
*Appropriate education programmes, measurement of
sources can be effective in promoting changes in disposal
practices that ultimately reduce the amounts of plastic
entering the environment.
*Plastic Waste Management has assumed great
significance in present day context. Various schemes has
to be implemented to mitigate the impacts of plastic waste
across the world.
