Grade-dependent flexibility
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.

THE NAME, EXPLAINED
What is PHA?
PHA means Polyhydroxyalkanoates.
A family of polyesters produced by microorganisms, with properties that vary substantially by chemistry and formulation.
Worth knowing
An environmental claim is not a collection instruction. Identify the exact PHA grade, blend and approved end-of-life route.

Properties with a practical purpose.
Polyester chemistry
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.
Biologically produced polymer family
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.
Properties vary with formulation, reinforcement, moisture, processing and service conditions. Use the exact grade data sheet for engineering decisions.
THE NEXT-CYCLE QUESTION
What matters when considering recovery?
A known grade and a clean, separated batch make the recycling enquiry more useful. A route must still be agreed.
An environmental claim is not a collection instruction. Identify the exact PHA grade, blend and approved end-of-life route.
Poly-Cycle can discuss your material information and collection requirements. Inclusion in this guide does not confirm acceptance, a particular recycling method or that every operation takes place at a Poly-Cycle facility.
How assessment and collection workMake the enquiry easier
- Confirm the identity. Keep the manufacturer, trade grade and polymer marking. For an additive or chemical, include the safety data sheet.
- Describe the batch. Give the weight, colour and form: pellets, parts, sheet, film, fibre or another format.
- Explain what else is present. Declare fillers, coatings, metal inserts, other polymers and previous contact with chemicals or other contaminants.
- Agree the route. Share photographs and your collection postcode before arranging a movement.
