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.

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 ?

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.

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 OTHERS

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.

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.

Processing

Segregation

Selection

METHODOLOGY

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.

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.

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

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.

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.

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.

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.
