## Summary

A WPC product contains a polymer component, so claims about particle release need specific evidence. The absence of visible damage does not prove zero microplastic release.

## Practical method

Ask what was measured, under which abrasion or weathering conditions, and how the results relate to the proposed use. Distinguish evidence about one formulation from claims covering every composite. For an illustrative waterfront specification, plan collection of machining dust and cleaning debris instead of allowing waste to enter water. Record the available evidence and its limits. Do not invent release rates or describe a product as microplastic-free without a sound basis. Environmental communication should remain as precise as the underlying testing.

## 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.

## Key points

Defined test conditions
Formulation relevance
Dust and debris collection

## Comparison

Design check | Evidence to record
Defined test conditions | Show the requirement on the project drawing
Formulation relevance | Obtain applicable product or design evidence
Dust and debris collection | Assign installation and maintenance responsibility

## WPC and microplastics: making defensible environmental claims — What should be confirmed before ordering?

A WPC product contains a polymer component, so claims about particle release need specific evidence. The absence of visible damage does not prove zero microplastic release. Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation.
