Processes, Stages, and Benefits of
Plastic Recycling
“I’m
mad keen on recycling because I’m worried about the next generation and where
all this waste we’re producing is going. It has to stop. I wash out my plastic
containers and recycle envelopes, everything I possibly can.”
A
lot of us believe in recycling and practice it daily just like actress Cherie
Lunghi. Plastic recycling is imperative in making sure that natural resources
are returned to nature to ensure their sustainability. Plastic was supposed to
be the wonder product of the 20th century, but the toxic waste created by it is
has been dangerous. Therefore, it has become imperative that we recycle all plastic waste.
What is Plastic Recycling?
Plastic recycling is
the process of recovering different types of plastic material in order to
reprocess them into varied other products, unlike their original form. An item
made out of plastic is recycled into a different product, which usually cannot
be recycled again.
Stages in Plastic Recycling
Before
any plastic waste is recycled, it needs to go through five different stages so
that it can be further used for making various types of products.
- Sorting: It
is necessary that every plastic item is separated according to its make
and type so that it can be processed accordingly in the shredding machine.
- Washing: Once
the sorting has been done, the plastic waste needs to be washed properly
to remove impurities such as labels and adhesives. This enhances the
quality of the finished product.
- Shredding: After
washing, the plastic waste is loaded into different conveyer belts that
run the waste through the different shredders. These shredders tear up the
plastic into small pellets, preparing them for recycling into other
products.
- Identification
and Classification of Plastic: After shredding, a
proper testing of the plastic pellets is conducted in order to ascertain
their quality and class.
- Extruding: This
involves melting the shredded plastic so that it can be extruded into
pellets, which are then used for making different types of plastic
products.
Processes of Plastic Recycling
Among
the many processes of recycling plastic waste, the following two are the most
popular in the industry.
- Heat
Compression: This type of plastic recycling is gaining special
demand in the United States, Australia, and Japan because
of its ability to recycle all types of plastic at once. It takes unsorted
and cleaned plastic waste and mixes it in huge tumblers that churn the
entire mixture. The major advantage of this process is that it does not
require matching forms of plastic to be recycled together.
- Monomer: Through
the elaborate and accurate monomer recycling process, major challenges of
plastic recycling can be overcome. This process actually reverses the
polymerization reaction in order to recycle the same type of condensed
polymer. This process not only purifies but also cleans the plastic waste
to create a new polymer.
Benefits of Plastic Recycling
After
knowing the processes and stages of plastic recycling, it is also important to
know its various benefits. A few of them are:
- There’s
A Ton of Plastic: One of the biggest reasons for
recycling plastic is its huge quantity. It has been observed that 90% of
the waste accumulated by the municipal corporation is a plastic waste.
Apart from this, plastic is used for manufacturing various types of goods
and items that are being used on a daily basis. This will not only help
increase the production of plastic but will also take care of the
environment.
- Conservation
of Energy and Natural Resources: The recycling of
plastic helps save a lot of energy and natural resources as these are the
main ingredients required for making virgin plastic. Saving petroleum,
water, and other natural resources help conserve the balance in nature.
- Clears
Landfill Space: Plastic waste is accumulated on land
that should be used for other purposes. The only way this plastic waste
can be removed from these areas is by recycling it. Also, various
experiments have proven that when another waste material is thrown on the
same ground as plastic waste, it decomposes faster and emits hazardous
toxic fumes after a certain period. These fumes are extremely harmful to
the surrounding area as they can cause different types of lung and skin
diseases.
Plastic
recycling not only promotes proper utilization of plastic waste
but also helps conserve the environment, making it cleaner and greener.
