PET (Polyethylene terephthalate) belongs to the polyester family, it can be used for many purposes such as plastic bottles and filter cloth as it is thermoplastic polymer. [5] PET can be degraded by using aminolysis which works similarly to solvolytic reaction and aminoglycolysis.
The National Association for PET Container Resources (NAPCOR) defines PET as: "Polyethylene terephthalate items referenced are derived from terephthalic acid (or dimethyl terephthalate) and mono ethylene glycol, wherein the sum of terephthalic acid (or dimethyl terephthalate) and mono ethylene glycol reacted constitutes at least 90 percent of ...
The first enzyme of the PET degradation pathway, PETase, cleaves this plastic into the intermediates MHET (Mono-(2-hydroxyethyl)terephthalic acid) and minor amounts BHET (Bis-(2-hydroxyethyl)terephthalic acid). MHETase hydrolyses the ester bond of MHET forming terephthalic acid and ethylene glycol. Enzymatic PET degradation by PETase and MHETase

The first PETase was discovered in 2016 from Ideonella sakaiensis strain 201-F6 bacteria found from sludge samples collected close to a Japanese PET bottle recycling site. [1] [4] There were other types of hydrolases previously known to degrade PET, [2] including lipases, esterases, and cutinases. [5]
In chemistry, ammonolysis (/am·mo·nol·y·sis/) is the process of splitting ammonia into + +. [1] Ammonolysis reactions can be conducted with organic compounds to produce amines (molecules containing a nitrogen atom with a lone pair, :N), [2] or with inorganic compounds to produce nitrides.
