First
Plastic Item- The first commercial plastic
product was
the foam
cup. That was made by Edward J. Stovesof the Koopers Company in
Pittsburgh, PA.
A
Inportant
Breakthrough- A breakthrough in plastic has
come from the use of natural materials such as (chewing gum) to the use
of chemically modified natural materials such as (ruber) and finally to
completely synthetic molecules such as eproxy and polyvinyl chloride.
Plastics advatanges-
Adaptabble, easy to work, high
strength, resistant, economical, environment, no maintanace, protects
other objects, and requires no labor to assemble.
FUN FACTS
Recycling a single plastic bottle can conserve
enough
energy to light a 60W bulb for up to 6 hours.
9.1 billion plastic bottles were disposed of in
2002
with only 360 million of them being recycled.
In Britain they about 275,000 tonnes of plastic
bottles in there homes every year- that's about 15 million bottles
every
day.
It takes about 450 years just for one plastic
bottle to
break down in the ground!
An average 323 plastic bags are taken into our
homes
every year and it takes 500 years to decay when sent to landfill.
It takes about 25 recycled plastic drinks bottles
to
make one fleece jacket.
Only 2.5% of plastic bottles are presently
recycled in
Europe.

How
is Plastic Recycled?
Your plastic bottles are collected either by the
waste
operator, or from plastic bottle banks (found at recycling centres or
bring sites) and they are taken to a material reclamation facility
(MRF) where they are sorted into their different types. There is a
special machine that can scan each bottle to determine what type of
plastic it is for example HDPE, PET and PVC.
Once the bottles have been sorted, they are then
squashed into blocks and sent to the balers to be baled.
The bottles are then taken to a flaking plant
where
they are chopped into little plastic chips. The plastic is then cleaned
to remove any paper labels and dirt. The bottles are then spun and
dried with hot air.
The plastic chips are then bagged and sold for
reprocessing.
The clean plastic chips are melted down and used
to
make lots of new items. These include new plastic bottles, anoraks,
sweaters, carpets, pipes, electrical fittings and garden furniture.
