What is Recycled Polyester?



Whilst not the complete solution to the world's issues, it is a step in the right direction!


To understand the relevance, it is important to understand the production process and its associated benefits.


1. Recycled Polyester – How is it Different?


  • Recycled Polyester uses PET (plastic bottles) as the raw material.


2. The processes involved...


  • Collected PET bottles are sterilised, dried, and crushed into small flakes

  • The Flakes are then put through a depolymerisation and re-polymerisation process and converted to chips

  • The chips are then heated and passed through a spinneret to create strings of yarn.

  • The yarns are then passed through a crimping machine to create a fluffy yarn texture.The yarn is then baled, dyed, and knitted into Polyester fabric.


3. Ecological Benefits


  • This process uses much less energy (nominally 35-50% less) than is required to produce virgin polyester yarn.

  • This process reduces the dependency on petroleum as the raw material

  • Utilising PET bottles for this process reduces landfill, thus less soil contamination air and water pollution.

  • Recycled Polyester can be recycled over and over with little to no degradation of quality allowing wastage minimisation.

  • As processes develop, this means polyester has the potential to become a closed loop system, whereby it is used, recycled, and reused again.

  • In this case the non-biodegradability of polyester could be a good thing.
