Polyethylene terephthalate is one of the remarkable polyester materials utilized
in various industrial, commercial and domestic applications. It remains as one of the
major raw material in many appliances such as textiles, beverages, food packaging,
water bottles, kitchen containers, hearing aids, thin films, sheets, sports items, construction materials, wrapping materials, etc., Out of the various PET material used the
bottle grade PET is one of the widely used polymer material in the current scenario.
Majority of the food packaging, water bottles and beverages holding containers are
made out of the PET materials, Moreover, these bottles comprise about 83–84% of
worldwide PET material demand. It is reported that the anticipated interest for PET
bundling materials is determined to achieve 20 million tons by 2019 with a yearly
increment of 4.6%. This elevated utilization of the PET substantially increased the
emission of large amounts of PET waste into the environment [7]. The total worldwide consumption of PET in various forms for different applications is depicted in
Fig. 2. Due to their unique properties, they are utilized in various applications such
as Water bottles, Food packings, Medications, Textiles, Carpets, Audio cassettes,
insulation tapes, automobile parts, electrical hardware compounds, and fabrics.
3 Need for Recycled Polyester
The textile industry is one of the major industry required for maintaining the lifestyle
of human beings, therefore the requisition of textile fiber is augmenting globally. In
this case, two major fibers such as cotton and polyester command the overall textile
industries. Within a short span of fifteen years, the polyester fibers have overwhelmed
the cotton fiber as the single most prevalent material [11]. The pollution caused due
to plastic creates an extensive dispute among mankind; furthermore, the toxic and
non-degradable nature of the plastic materials complicates the ecosystem [8]. The
extended utilization of polyester has increased the emission of polyester waste into
