ABSTRACT
Polyethylene terephthalate (PET) is the most popular member of the polyester family, which is the most consumed and recycled among the engineered polymers. PET has been known for its thermal and mechanical performance, transparency, barrier property, thermoformability, and, lately, curbside recyclability, thanks to the infrastructure in the waste management. It made clear advances in beverage bottle, food tray, construction, structural, transportation, and packaging [1,2]. In recent years, its recyclable status made it a favorite in the environmental push. Virtually, it drew signicant amount of efforts in research and development in recycle and reuse and in product
