WHAT IS PLASTIC AND ITS TYPES
• Plastic is a chemically produced substance that can be molded into a permanent object.
• TYPES: Thermoplastic Polymer. Thermosetting Polymer.
SYNTHESIS OF PLASTICS
Oxygen,170 deg. C Ethylene Polythene 1000 atm
• The per capita consumption of plastic in the country
stood at 6 kg now and is expected to go up to 12 kg by 2011.
• By 2012, India is also projected to be the third largest consumer market for plastic goods with a consumption of 12.5 million tonnes per annum, behind US and China
Statistics
How does plastic waste
impact our oceans?

Ocean currents carry them and form huge whirlpools (gyres) of plastic. Have you heard of the Great Pacific Garbage Patch? An island of plastic 6 times the size of Vietnam.
From Sea to Summit Recap - PollutantsPLASTICS
Great Pacific Garbage Patch• a gyre of marine debris in Central North Pacific Ocean.
(gyre: a swirling vortex created by large ocean currents)• over 300,000 pieces of plastic/sq. mile • Twice the size of Texas and growing• plastic outnumbers plankton 6 to 1. • 80% of plastic from land-based sources, 20% from ships• plastic longevity ranges from 100 - 1000 years
Plastic bags pose a serious danger to birds and marine animals that often mistake them for food. Thousands of marine animals and more than 1 million birds die each year as a result of plastic pollution. Also, plastic is toxic.

Disadvantages of Plastic Bottles
Decomposition
Non-Renewable
Hard to Reuse
Difficult to Recycle
How do we solve this problem together?

ALTERNATIVES
• Plastic bags take between 15 to 1000 years to degrade. The detoxins and other chemical pollutants released fromthem are a Serious Threat to be Tackled.
• Paper , Cloth, Jute, Cane, etc., are the most preferable but still controversial

Plastics From Garbage!
• Recently scientists have made a green polymer from plastics thrown in the garbage which will prevent dumping of post consume plastics in the landfills.
• Banning plastics is not the real motto to save the environment but the motto is to make plastics in producing wide varieties of products.

5-R for Plastics!!
• Refuse• Reduce• Reuse • Recycle• Rebuy
THINK TWICE•Do you really need a bag for your bag of chips?•Ask the waiter to wrap in foil instead of Styrofoam•Ask for “no straw”•Don’t buy things with excess packaging•Buy the can instead of the plastic bottle•Shop at the local farmer’s markets•Bring your own salsa/jam jar to parties. Its free!
REFUSE, REDUCE, REUSE… then RECYCLE
Plastic Waste Management in India
Categories :
• Primary recycling.
• Secondary recycling.
• Tertiary recycling.
• Quaternary recycling.
“ The BMC's proposal, which is being scrutinized by its legal cell before being forwarded to the Maharashtra government, suggests a
fine of Rs 5 to Rs 10 on anyone found carrying material in bags that of less than 50 microns thickness.”
BRING YOUR OWN• WATER BOTTLE
(stainless steel)• BAG• CUP• TUPPERWARE• SILVERWEAR• REUSE A GLASS JAR
Spread the Word…with a SMILEShare what you’ve learned • Lead by example• Ask your friends and family to
join you• Speak to city council• Write letters to government
officials• Get your school involved• And come to the Plastics Are
Forever Youth summit in 2011!
