Switching from virgin to recycled polyester filling: what to check

1. Define the baseline

Treat the switch as a material change to evaluate, not an automatic like-for-like replacement. Record the current filling specification, product construction, filling weight and process settings. Keep a reference sample of the existing finished product where practical.

Agree which criteria the new filling must meet before the trial. These might include feel, volume, recovery after compression and behaviour under the intended care conditions. Separate essential requirements from preferences so the trial has a clear purpose.

2. Run a production trial

Compare the candidate filling with the baseline using your actual product and a representative production setup. Record any changes needed to equipment settings, material handling or filling weight. These observations belong in the decision alongside the finished-product assessment.

Use the same evaluation conditions for both samples. If the new filling needs a different construction or process, record that explicitly rather than presenting the comparison as a direct material substitution.

3. Check supply consistency

Ask how the agreed specification will be maintained between deliveries and how changes will be communicated. Discuss sample identification, batch references and the information available for incoming checks.

Confirm availability, order quantities and lead times before planning a changeover. Decide who will approve the material and how existing and new stock will be identified during the transition.

4. Verify traceability

Confirm the recycled-content information and supporting documentation required for the selected material. Check what each document covers and which information will accompany deliveries. Do not assume that recycled content means certification.

Keep material approval separate from approval of finished-product wording. Any statement about the recycled content of a pillow, duvet or cushion must match the product and evidence it describes.

Can we keep the same filling weight?

Use it as a starting point for comparison, not a guaranteed final specification. Assess the finished product and record any adjustment needed to meet your requirements.

Is a successful sample enough to approve the switch?

It is one part of the decision. Review the production trial, agreed material specification, supply arrangements and documentation before approving the changeover.
