Recycled Wool

Why recycled wool is worth understanding

Recycled wool is seen as a key opportunity for brands, both for circularity and for emission reduction strategies. Yet technical limitations, sourcing hurdles and design trade-offs can make it difficult to scale in collections.

Recycled wool quality starts with the feedstock. Pre-consumer waste covers production offcuts, surplus yarns and manufacturing waste; post-consumer waste is garments collected after use. Both play an important role, but post-consumer materials typically require more sorting, testing and quality control. As wool products increasingly contain blends of different fibres, sourcing suitable feedstock for high-quality recycled wool may become more difficult. At the same time, recycling technologies are evolving quickly: advances in mechanical recycling help preserve longer fibre lengths, improving both yarn quality and product performance.

Circularity comes with trade-offs. Working with the colours the sorting process produces, instead of dyeing again, reduces environmental impact but limits colour flexibility compared with virgin fibres. Recycled materials may need new design approaches and different consumer expectations. One of the biggest challenges is understanding exactly what enters the recycling stream: chemicals of concern, and small percentages of unknown fibres. Demand is likely to grow as circularity matters more to brands and policymakers, but feedstock, infrastructure and processing capacity remain open questions.
