6. Polyethylene Terephthalate Recycling Process

Polyethylene terephthalate (PET) is the major constituent of products such as plastic fibers, video tape, audio tape, film, and food and beverage containers.  In this process, PET is hydrolyzed into its component monomers, terephthalic acid and ethylene glycol, under extreme alkali conditions, using KOH.  The monomers are recovered, and the KOH is regenerated for re-use.  Thus, this process "green" because it has zero emissions.
