Thus, the Petretec process allows for the conversion of scrap PET into its monomers, which can then be polymerized again to produce first-quality PET. These polymers can even be used in beverage containers regardless of the previous life of the scrap PET. The Petretec process not only allows for closed-loop recycling of PET but concomitantly reduces the amount of virgin p-xylene and ethylene glycol that needs to be produced from crude oil for use as PET feedstocks.
