Abstract
One of the most serious threats to the environment in today’s world is plastic pollution. The reason for widespread of plastic is its poor disposal management, indiscriminate use of plastic and its related products. There was a tremendous increase in the production of plastic from the start of 21st century due to its high demand which tripled the waste in these two decades. This review papers aims at providing the understanding of various techniques used for PET plastic degrading process and currently used in large scale that is quite detrimental to the environment. Further, the recent discovery of the bacteria eating enzyme provided a shaft of light in waste green recycling process. Adding to this, there is an outline provided for bioengineering of the most preferred enzymes for hydrolysis process result is compared that which one is more efficient one. Comparing them and trying to exploring the potential of various mutated enzymes for hydrolyzing of plastic waste formulated by various researchers to identify the Nobel PET catalyst which can solve the massive environment crisis when used in large-scale.
Highlights
Polyethylene terephthalate (PET or PETE) aromatic polyester of family polymer is ageneralpurpose thermoplastic POLYMER that consists of non-hydrolyzable covalent bond [1]
There is no effect of solar radiation and UV on degrading process of these are dumped in river, oceans, landfills including terrestrial environment that is lethal to marine animals [911]
From time to time there has been a great advancement in the treatment of the waste accumulated through plastic
Summary
Polyethylene terephthalate (PET or PETE) aromatic polyester of family polymer is ageneralpurpose thermoplastic POLYMER that consists of non-hydrolyzable covalent bond [1]. When used for fabrics it is known as polyesters and in case of bottles, container, packaging applications it is called as PET or PET Resin [2].There are two ways to obtain the product from polycondensation reaction of monomers. Trans-esterification occurring between the monomers named terephthalic acid and ethyleneglycol. Esterification reaction of monomers, ethylene glycol and terephthalic acid [3,4]
