Technology to Recycle Plastic Bottles
Polygenta’s proprietary, commercially proven technology that produces polyester filament yarn from post-consumer waste PET bottles, is executed at 15000 tonnes per annum recycling facility in Nashik, India.
The process is a trailblazer technology given its ability to recycle dirty clear and PET bottles in a cost-effective manner as well as significantly reducing the use of virgin petrochemical feedstock and delivering superior quality products.
The traditional forms of recycling are either expensive or unreliable.
Mechanical recycling is unable to effectively remove colours and other contaminants from PET, thus resulting in lower / inconsistent quality end-products, whilst the very few chemical recycling (which decomposes PET into its individual “monomers”) processes around are highly expensive. Given these challenges, recycled material commands significant premiums on virgin PET.
The process is able to capitalize from these premiums by recycling cost effectively, whilst yielding greater quality products than traditional recycling processes.
The process uses a solvent to dissolve PET flakes into liquid form before applying filtration technologies to yield pure esters (which can then be recombined into high grade polyester products).
Compared to virgin esters the recycled esters are indistinguishable,
