PET Bottles

While most thermoplastics can, in principle, be recycled, PET bottle recycling is more practical than many other plastic applications.  The primary reason is that plastic carbonated soft drink bottles and water bottles are almost exclusively PET.  PET has a resin identification code of 1.

Processing examples for recycled polyester
Recycling processes with polyester are almost as varied as the manufacturing processes based on primary pellets or melt. Depending on purity of the recycled materials polyester can be used today in most of the polyester manufacturing processes as blend with virgin polymer or increasingly as 100% recycled polymer.
