Circularity Scoring
Alongside the PEFCR carbon footprint, every passport carries two circularity scores on a 0–100 scale, derived using the EU Joint Research Centre (JRC) repairability and recyclability framework. They are computed deterministically from data already on the product — no LLM, no manual grading — and flagged estimated until a full component bill-of-materials is supplied.
Recyclability score
How readily the product can be recycled at end of life. Weighted from:
- Material homogeneity — a mono-material product recycles far more easily than a blend. Measured with a Herfindahl index of fibre shares.
- Material recyclability — each fibre’s recyclability today (e.g. polyester and cotton high, elastane very low). Elastane present anywhere applies an additional penalty, as it blocks mechanical recycling.
- Component separability — removable trims and hardware can be taken off before recycling. Products with no declared components are treated neutrally.
- Declared recyclable — the brand’s recyclable yes/no flag.
- Recycling guidance — whether recycling instructions are provided.
Repairability score
How easily the product can be kept in use through repair. Weighted from:
- Repair information — whether repair instructions are provided.
- Material durability — the expected wear life of the fibres used.
- Expected lifespan — parsed from the declared lifespan (years or wash cycles).
- Component separability — removable parts make repair easier.
Recycled content
The overall recycled-content percentage is the share-weighted average of each material’s recycled %. It is shown on the passport and also nudges the recyclability score.
Why “estimated”
The scores are a transparent, rules-based estimate — not a certified rating. They sharpen as you add detail: declaring a component BOM, recycled percentages, repair instructions and an expected lifespan all feed the calculation. Add a removable-component breakdown and the recyclability score reflects real disassembly potential rather than fibre composition alone.
