Bottles made of polyethylene terephthalate can be used to make lower grade products, such as carpets. To make a food grade plastic, the bottles need to be hydrolysed down to monomers, which are purified and then re-polymerised to make new PET.
PET or PETE 1 is a common type of plastic used for packaging. It is transparent, lightweight, strong, and has good barrier properties. PET is easily recyclable and is commonly used for beverage bottles and food containers. It is not recommended to reuse disposable PET drinking bottles.
