Polyethylene terephthalate (PET) is made from two raw materials namely PTA and MEG.
Polyester Staple Fiber (PSF) has emerged as the fastest-growing fiber amongst all types of manufactured fibers. Polyesters are made by polymerisation of Purified Terephthalic Acid (PTA) and Mono Ethylene Glycol (MEG). The polymer thus obtained is melt spun and the bundle of continuous filaments obtained by melt spinning is called tow. The tow is subjected to further processes like drawing, crimping, spin finish application and then cut into fixed lengths to get cut fibers almost equal in length to cotton fibers. These cut fibers are known as PSF.
The PET has following three applications:
Commonly used in manufacturing of plastic films which are used as plastic wrapping for different kinds of product such as cigarettes box.
Used for production of preforms, which are then blown for making PET bottles for usage in beverages industry.
Used in textile industry and in filling of cushions and sofa etc.
Out of above three polyester products, only PET bottles can be recycled for either production of rPSF or rPET bottles.
Why Should You Recycle?
- Recycling saves energy
- Recycling saves our clean air and clean water
- Recycling conserves our natural resources
- Recycling saves landfill space
- Recycling saves money and creates jobs
Why Recycle PET
- Recycling a single PET bottle can conserve enough energy to light a 60 watt bulb for up to 6 hours.
- Recycling one ton of plastic bottle can save 1.5 tonne of CO2.
- Recycling one ton of PET saves 7.4 cubic yards of landfill space.
