Plastic waste Management & Recycling Technology
22/08/14 – In Project Proposal
INTRODUCTION OBJECTIVES INVOLVED CASE STUDY EXISTING PROBLEMS REMEDIAL MEASURES CONCLUSION REFERENCE
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. Making our Eco fest - 15------Plastic free & Models

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.

Waste to Power Generation Method
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.
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.
Conti…
Bio degradable plastics - Manufacture of plastics that are eco-friendly. They have a decomposing nature.
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
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
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.
