PET Recycling

Polyethylene Terephthalate (PET) recycling is the process of recovering PET plastic waste for reuse as new products. 

PET plastic is a commonly used packaging for many household items, such as soda and water bottles and microwavable food trays. It can be identified by a #1 symbol located on the package. 

PET plastic is easy to recycle, as it has a low melting temperature. After processing, recycled PET plastic can be turned into new plastic containers, fibers to make clothing, carpet and more.
