As a synthetic fiber, polyester is proving particularly suitable for reuse in applications where the recycled material is indistinguishable from material made using virgin petroleum products. The seat fabric in the Audi A3 is an example where material recovered from polyethylene terephthalate (PET) plastic bottles is used to make the car’s upholstery.

PET is is a general-purpose thermoplastic polymer that belongs to the polyester family of polymers. These are good recycling candidates because polyester resins are known for their mechanical, thermal, chemical resistance as well as dimensional stability.

TWD Fibres GmbH, one of Audi’s partners in the process of creating automotive seats from recycled water bottles, lists five reasons to recycle PET:

Audi has provided us a look at the process of going from bottles to seats from start to finish, so click through our photo gallery to see how it happens.

Can you guess how many bottles go into the creation of a pair of car seats? Check out Slide 10 to see how close you are to the real deal.
