3. objectives
To emphasize the reduced use of plastic and the beneficial
management of plastic waste.
Efficient transformation of plastic into energy and fuel.
Making our environment an eco friendly zone.
Modify the design of recycling Machines.
Install the recycling unit at TNAU.
Compare the envi.factors of Coimbatore with other
cities.

8. Recycling technology
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.
9. forms of recycling

2.Chemical Recycling
11. 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.
12. Alternatives to be considered
Plasma Pyrolysis Technology
Incineration of waste by plasma
torches leaving minute or
no residues.
Dehydrochlorination
Conversion of plastic waste into Liquid fuel using
units. By extracting hydrogen and chlorine separately
oil and hydrochloric acid can be obtained.
13. Conti…
Bio degradable plastics - Manufacture of plastics
that are eco-friendly. They have a decomposing nature.
14. 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 breakdown ,these are renewable
15. Treatment & Separation Technique
1.Wet Separating Techniques
Flotation of mixed plastics utilizing selective wetting
characters in order to change the surface of specific
plastics from hydrophobic to hydrophilic
2.Dry separating Techniques
Especially PVC from mixture of plastics, Low capital
Input, means it is environmentally friendly
16. 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.
21. Data of TNAU
