3. INTRODUCTION
Waste is now a global problem, and one that must be addressed in
order to solve the world's resource and energy challenges.
Plastic is a material in any of a wide range of
synthetic or semi synthetic that are moldable. These are made from
limited sources of a petroleum. Huge advances are being made in
the development of technologies to recycle plastic waste among
other resources.

4.  It gives to energy savings and the reduction of greenhouse gas
emissions. It also saves non renewable sources like oil and gas. In
addition to that, recycling provides livelihood for millions of
people and families in developing countries, employment or
informal economic activities.
Why recycle plastics ?

5. OBJECTIVES
 The main objective of this project is to emphasize the
reduced use of plastic and the beneficial management of
plastic waste. This also includes alternative measures for the
substitution of the synthetic polymers.
 Efficient transformation of plastic into energy and fuel.
 Controlling the impact of plastic waste on the environment.
 Making our environment an eco friendly zone.

6. CASE STUDY
 Plastic is a form of synthetic or semi synthetic organic polymer.
Plastic can be manufactured through various processes and by
combination of various compounds. The variety of plastics are
discussed as follows.
PET HDPE PVC LDPE PP PS
OTHE

7. DESCRIPTION
 PET : Poly Ethylene Terephthalate-fizzy drink bottles and oven
trays manufacturing
 HDPE : High Density Poly Ethylene-bottles for milk and washing
up liquids
 PVC : Polyvinyl chloride, Pipes and fittings
 LDPE : Carrier bags and garbage bin liners
 PP : Poly propylene, Medicine bottles
 PS : Poly Styrene, Packaging pellets, Fast food trays etc.

10. ENVIRONMENTAL IMPACT ASSESSMENT
 Plastic manufacturing consumes significant amount of resources.
(4% of worlds annual oil production)
 Littered plastic spoils the beauty of the environment
 Affects human health due to toxic release into atmosphere.
 Non bio degradable nature arrests recharge of ground water
aquifers.
 Garbage mixed with plastic may cause problems in landfill
operations.

11. Processing
Segregation
Selection
METHODOLOGY

12. Methodology
 Selection - The recyclers have to select the waste
suitable for recycling.
 Segregation - The plastic waste must be separated
according to its nature corresponding to BIS guidelines
 Processing - After segregation pre consumer waste
can be directly recycled whereas post consumer
waste has to be washed ,shredded ,agglomerated and
granulated.

13.  Primary recycling - Involves processing of waste
into a product of similar characteristics.
 Secondary recycling - Involves processing of waste
plastic into materials having different characteristics.
 Tertiary recycling - Involves production of basic
chemicals and fuel from segregated municipal waste.
 quaternary recycling - Involves energy extraction
by burning and incineration.

15. DISADVANTAGES
 High Initial cost.
 Recycled products may not last for long.
 Unsafe and unhygienic recycling sites.
 May create more pollution.
 Not wide spread on large scale.

16. ALTERNATIVES TO BE CONSIDERED
 Plastic waste disposal through Plasma Pyrolysis
Technology - incineration of waste by plasma torches
leaving minute or no residues.
 Conversion of plastic waste into Liquid fuel using
Dehydrochlorination units. By extracting hydrogen and
chlorine separately oil and hydrochloric acid can be
obtained.
 Bio degradable plastics - manufacture of plastics that are
eco-friendly. They have a decomposing nature.

17. ADVANTAGES
 Plasma Pyrolysis - Clean destruction of hazardous
waste Preventing waste from entering landfills
No harmful emission of toxic waste.
 De-hydro chlorination – Extraction of clean energy and
Hydrochloric acid.
 Bio Degradable plastic – Takes less time to break down
Bio plastics are renewable.

19. A LENOVO ENVIRONMENTAL SUCCESS STORY
“USING RECYCLED CONTENT PLASTICS”
 To demonstrate “engineered” recycled content plastics could
successfully be used in computer applications and satisfy the
demanding requirements, Lenovo’s team first worked with post
industrial content (PIC) recycled plastics.
 To prove to the computer industry using recycled plastics is not
only the right environmental thing to do, but makes good
business sense.

21. CONCLUSION
 Even though plastic recycling and its management
has gained momentum nowadays, the best possible
way of protecting our environment is to alter the
root cause of the problem by reducing the usage at
the preliminary level.
