Set a fair functional comparison
Compare materials that deliver the same required function for a defined service life. Account for mass, energy use, manufacturing losses, transport and maintenance. A lighter material is not necessarily better if it fails early or requires more frequent replacement.
Interrogate the evidence behind claims
Ask whether recycled content, bio-based sourcing or carbon figures are verified and which boundaries were used. Lifecycle assessments can support comparison when assumptions and data quality are transparent. Avoid broad “eco-friendly” claims without a specific measurable basis.
Consider recovery at the product level
End-of-life outcomes depend on local collection systems, product design, additives and contamination. Evaluate repair, reuse and recycling feasibility in the intended market. Document trade-offs clearly so procurement and design teams can revisit decisions as technology and infrastructure change.
Practical checklist
- Compare equivalent functions and service lives.
- Ask for boundaries and verification behind claims.
- Evaluate real collection, reuse and recycling options.
