RECYCLING OF PLASTIC

2.  Plastic Recycling is the process of recovering
waste or plastic cut offs and reprocessing it into
a new product.
 These days, plastic is posing serious littering
problem in cities and around collection points
and dumping sites. With an average, 8% by
weight of the total amount of domestic waste,
plastic is one of the major constituents in waste
stream.
 Plastics are non-biodegradable and that is why
it’s important to recycle it.

3.  PET (Polyethylene Terephthalate) can be recycled into
plastic fibers, injection moulding, non-food grade
containers.
 PVC (Polyvinyl Chloride) can be recycled into decks,
roadway gutters, flooring, cables, speed breakers and
mats.
 HDPE (High Density Polyethylene) can be recycled
into laundry detergent bottles, oil bottles, pens, floor
tiles, fencing,drums, toys, pipes, sheets and plastic
pallet etc.
 Some other types of plastics include LDPE (Low
Density Polyethylene), polystyrene, polypropylene.

4.  Plastic Recycling helps in reducing the cost
of raw material and energy saving.
 Recycling helps in mitigating global warming
and in reducing pollution.
 Recycling minimizes waste products placed
in landfills.
 Conservation of resources.
 Plastic recycling also helps in employment
generation along with reduction of volume
transport.

6.  COLLECTION: Plastics come in a variety of products
such as plastic containers, bottles, bags, etc. Tonnes of
plastics are collected and then sent to the plastic
processing plants.
 SORTING: It needs to be sorted into individual bundles.
They can be sorted according to the resin content and
colour.
 SHREDDING: After sorting plastics are shredded or
broken down into tiny pieces by the help of machine
grinders.
 CLEANING: After shredding, the plastic pieces are
washed with the necessary detergents to remove the
remaining contamination.

8.  MELTING AND COLOURING: The plastic pieces are
then melted so that they can be moulded into new
shapes and blended with desired colour dye if required.
 EXTRUDING: The coloured material passes through an
extruder machine to produce thick plastic strands.
 CUTTING: The strands are manually cut into lumps and
these are used for manufacturing items either manually
or mechanically. In the manual process, the lumps are
further chopped into smaller pieces and melted. The
melted material is moulded into products such as shoe
soles, toys and boxes. Machineries used in this process
are electrically operated crusher, extruder, mixer and
manually operated moulding machine (in which material
is electrically heated at 359⁰C).
