Coextruded PET Preforms Nylon Barrier Liberated - Both Plastics Recovered

 

Problem / Opportunity:
We were approached to find a way to separate Nylon from PET to recover PET. Bottle preforms can be coextruded with a Nylon barrier (above) sandwiched between two layers of PET. Our customer (another recycler/scrap buyer) was forced to take these along with more salable scrap PET resin when they won the bid on clean PET scrap - yet no market existed for the PET Nylon preforms.

 

Impact on Customer:
The options available to the customer were as follows:

 

  • trash the material,
  • continue to accumulate and incur storage costs, or
  • export the material “as is”, provided they could find a buyer.


Based upon these options, the customer would incur significant losses compared to being able to sell the PET which was previously thought to be “unrecoverable”.

 

Solution for Customer:
Pre-shipment sampling confirmed that the nylon and PET could be separated with favorable economics. Using proprietary separation processes, Butler-MacDonald was able to liberate the nylon from the PET and then achieve separation from the desired PET fraction.

 

Benefit:
Butler-MacDonald delivered a PET yield and purity acceptable to the customer’s client, which resulted in the use of the material as originally intended, at the original sale price.
