At a glance
Polymer origin is one part of WPC specification, alongside consistency, traceability and demonstrated performance. Neither recycled nor virgin content alone proves suitability for a project.
Key points
- Percentage denominator
- Feedstock traceability
- Relevant performance evidence
Practical method #
Ask for the declared formulation, source controls and product-specific evidence relevant to the intended exposure. Clarify whether recycled-content figures refer to the polymer fraction or the whole finished product. For an illustrative procurement comparison, use the same basis for both offers and record whether figures are supplier declarations or independently verified. Assess environmental impact with appropriate life-cycle information rather than one ingredient percentage. A buyer can value recycled resources while still requiring dependable material control and installation evidence.
Planning and verification #
Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.
Handover and maintenance #
Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.

Common questions
Recycled or virgin polymer in WPC: what matters to buyers? — What should be confirmed before ordering?
Polymer origin is one part of WPC specification, alongside consistency, traceability and demonstrated performance. Neither recycled nor virgin content alone proves suitability for a project.
