PLASTICS - Boon or Bane? : 

PLASTICS - Boon or Bane? By Avni Singh Objective – To create awareness abot the use and effect of Plastics.

Familiar sight..? : 

Familiar sight..? 500 billion plastic bags distributed annually worldwide , and less than 3% of those bags recycled. They are typically made of polyethylene and can take up to 1,000 years to biodegrade in landfills that emit harmful greenhouse gases. (Time, 2007) 2 Each one can make a difference!

Human health hazard Phthalates, a chemical used to make plastics pliable, may have hormone disrupting effects on unborn baby boys; also linked to obesity and diabetes in men ( CBC News (2008), URMC Press(2007)) Enters food chain as it is ingested by sea and land animals Contd.

Whales hail for help!! : 

Whales hail for help!! As per Marrickville Council of Australia, as many as 100,000 whales, turtles and birds die have been reported to die every year, mainly because of plastic in their environment. Plastic bags not only have adverse effects on our natural habitats, but have also been found to be responsible for the death of many animals, mainly on account of the suffocation encountered on eating them. 10

Slide 15: 

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. Designing eco-friendly, biodegradable plastics is the need of the hour. Though partially biodegradable plastics have been developed and used, completely biodegradable plastics based onrenewable starch rather than petrochemicals have only recently been developed and are in the early stages of commercialization. Paper , Cloth, Jute, Cane, etc., are the most preferable but still controversial

The future of plastic is ‘not’ in jeopardy : 

The future of plastic is ‘not’ in jeopardy “Everything’s plastic, we’re all gonna die” says Elizabeth Wurtzel. I do not agree with the statement. Biodegradable plastic seems to show some light, however, they too come with certain disadvantages. When degraded, these emit harmful Co2 and methane. However, here comes recycled plastic curbstone, which acts as a substitute to building materials. In addition, “oxo-biodegradable” plastics are eco- friendly as when degraded they emit no methane. It’s time we change our opinion. Many developing countries like India are banning plastic bags. Instead of banning them, the plastic bags should be utilized elsewhere. 16

Let’s discuss about a few recent developments: : 

Let’s discuss about a few recent developments: • Plastic used in construction: Plastic building material is strong, flexible, water- and heat - resistant. Recently, a UK-based company has launched a recycled plastic curbstone, which can replace building materials like steel, wood, etc. The plastics are light weight and require little maintenance. Novacem Company has developed a new formula of locking CO2 into construction materials. The CO2 can be recycled with other plastic and glass from torn out buildings. 18

Making Plastics from Plants!! Wow! : 

Making Plastics from Plants!! Wow! • Scientists have come up with a new technology of making plastic from plant. Three bacterial enzymes have been introduced by the scientists in the model plant Arabidopsis thaliana. When the two enzymes are combined with the plant, an organic polymer known as polyhdroxybutyrate-co-polyhydroxyvalerate, or PHBV is produced. PHBV is extensively used to produce variety of products like grocery bags, soda bottles, flatware and disposable razors. The plastic when discarded are easily degraded. 19

Plastics From Garbage! : 

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. 6/6/2010 20

5-R for Plastics!! : 

5-R for Plastics!! Refuse Reduce Reuse Recycle Rebuy 26

Slide 27: 

It's impossible to eliminate most plastic from daily life, but it's prudent for our health and that of our environmentto curb the use of some. Overall reduction in plastic usage, proper management for disposal and public awareness would bring a great difference in present situation. Separate .. Store..and hand over for proper recycling or disposal. Do not let plastic litter the environment. SAVE EARTH OUR RESPONSIBILITY

Thus it all depends on us how we use it and mange it. :
