Recycling Plastic Bag

RECYCLING
PLASTIC BAG
Though plastic is a very useful material that is flexible, robust and rigid they become waste
after their use and they pollute the atmosphere. To protect the environment as well as to
take advantage of plastic, recycling procedure is used...

Plastic is a common material that is now widely used by everybody in this world. Plastic
is used in many ways as it is light weight and compact. The maintenance required is
little. Common plastic items that are used are bags, bottles, containers and food
packages. Whenever you buy grocery, food or any other item from any store, you will
use plastic bags for carrying them.
Uses of Plastic
Plastics are widely used in:
Packaging industry
Construction industry
Disposable cutlery
Storage, etc.
The ease of use of plastic items has made plastic a great success.
Where does the Problem Lie?
The great problem with plastic is its disposal. Plastic is made of polymer chemicals and is
not bio degradable. This means that plastic will not decompose when it is buried. When
plastic is burnt it emits harmful chemicals. These chemicals have adverse effects on the
environment. Hence, the need of recycling arises.
Recycling
Recycling means making new products out of the waste materials. All types of plastics
cannot be recycled. If we recycle the ones that can be, the environment will be saved
to some extent. Plastic recycling involves the process of recovering scrap plastic and
this waste plastic is then reprocessed to form new materials that may be different from
their original state. Compared to other materials like glass and metal, recycling of
plastic is expensive and complex. This is due to the high molecular weight of the large
polymer chains that build the plastic material. Heating plastic doesn't dissolve the
polymer chains and hence a tedious and complex process is essential. Different types
of plastic cannot be mixed together because they phase separate. Such a resulting
melting product cannot be recycled to make another plastic product. While making
plastic products many fillers like dues and other additives are used. These fillers cannot

e separated from the plastic using inexpensive techniques. This makes the process
more complex.
Advantages of Recycling
Recycling plastic has many advantages.
Use of non-renewable fossil fuels is reduced by
recycling as manufacturing new plastic
materials require more of these fuels.
Consumption of energy is also reduced as
already prepared plastic is recycled for new use.
Amount of plastic that reach the landfill sites are
greatly reduced. This will eliminate land pollution
to some extent.
Carbon emissions are reduced as manufacturing units emit more carbon.
Inverse Polymerization Process
The common process that is used for recycling polymers is the inverse polymerization
process where the polymers in the plastic are converted into initial monomers that were
used in the manufacture. These chemicals are then purified and synthesized to form
new plastic materials. Assorted polymers are converted into petroleum in another
process. The advantage of this process is that any mix of polymers can be used. A new
process generates heat from the friction of plastic materials which melts the plastics. This
is then pumped into casting molds. The great advantage of this technique is that all
types of plastics can be recycled.

Basic Steps Involved in Recycling
The basic steps that are involved in the recycling of plastic are;
Step 1: Collecting plastic waste from households as well as industrial wastes as
well.
Step 2: Sorting the plastic waste in different categories such as PET bottles, bags,
containers, etc.
Step 3: The Plastic is cut into tiny pieces.
Step 4: The tiny pieces are thoroughly washed for any dirt or unwanted particles
on them.
Step 5: The washed pieces are melted and poured into small containers for
reuse.
To aid the process, plastics come with plastic identification code to identify the different
polymers that are used in the manufacture of plastic. The process must be started from
home. When you have utilized that plastic item for its use you can use the same item for
something else. For example, if you buy a juice bottle you can use the plastic bottle as
a storage container for reusing the pet bottle.
Everybody must also be aware of the recycling plant in the locality and must bring the
waste plastic to the plant.
