## Summary

A useful sustainability comparison includes material quantities, production, transport, maintenance and end-of-life options over an equivalent function and service period.

## The technical principle

A long-lasting, repairable installation can avoid premature replacement, but assumed lifespan should not be treated as proven performance. The book's ageing mechanisms explain why moisture, heat and oxidation belong in durability assessment. Environmental conclusions require additional product-specific data rather than a universal claim about composites.

## What to specify and verify

Request an appropriate environmental declaration where available, with its scope and assumptions. Confirm recycled content separately from recyclability. Ask whether collection, separation and reprocessing actually exist in the project location. Mechanical fixings and replaceable components can help repair, but practical details determine whether disassembly is feasible.

## Application and common mistakes

Proximity can reduce part of the transport burden, yet does not establish the complete carbon footprint. Ask Green Plank about current material documentation, maintenance and realistic recovery routes. Avoid assigning a CO2 saving, circularity percentage or service life to a product without comparable supporting evidence.

## Discuss your project with Green Plank

For a Green Plank specification, request samples and current technical documents for the exact profile and intended application. Use the Green Plank link in Sources to explore the range and make an enquiry. Commercial disclosure: this portal features Green Plank. General material science does not certify any particular product.

## Key points

Comparison: Equivalent function and system boundary.
Use: Maintenance, repair and verified durability.
End of life: Available collection and recovery route.

Comparison | Equivalent function and system boundary
Use | Maintenance, repair and verified durability
End of life | Available collection and recovery route

## Does recyclable mean it will be recycled locally?

No. Technical possibility and an available collection-and-processing system are different things.
