Primark joins Denim Deal to scale recycled cotton in denim supply chain

Primark has joined the Denim Deal, a cross-industry collaboration in which brands, manufacturers, suppliers and recyclers share knowledge and tackle the practical barriers to putting more recycled cotton into denim production.

The membership gives the value retailer access to industry expertise, technical and sourcing support, and joint research and development opportunities. It targets a specific supply-chain problem: post-consumer recycled cotton still accounts for a small share of denim fibre inputs, and scaling it requires coordination across spinners, mills, garment makers and recyclers rather than any single tier acting alone.

For Primark's sourcing teams, the commitment is an extension of work already underway rather than a new pledge from a standing start.

What has Primark already delivered on circular denim?

Earlier this year, the retailer launched its first capsule denim collection made from reclaimed denim. Every product in the five-piece range contained a minimum of 20% recycled denim, produced by recycling discarded denim textiles back into new cotton fibre.

The collection was also engineered to remove common end-of-life recycling obstacles — stretch materials and unnecessary metal hardware such as rivets. That design detail matters commercially: hardware and elastane contamination are among the main reasons denim fails to enter fibre-to-fibre recycling streams.

The broader framework is Primark's updated Circular Product Standard 2.0, which concentrates on three areas: durability, materials and recyclability.

How much of the denim range qualifies today?

The number is modest but measurable. In 2024/25, 8% of denim units sold by Primark met its circular-by-design criteria — roughly one unit in every twelve. Through the Denim Deal, Primark intends to learn from other participants and identify practical routes to push post-consumer recycled cotton content higher across its denim assortment.

The retailer frames the membership as building on existing material commitments rather than replacing them.

What other offtake deals sit behind this?

Last month, Primark signed a multi-year offtake partnership with Circ to introduce recycled polyester made from textile waste into future product ranges, starting in 2029.

That agreement was a first for the company: its debut multi-year offtake deal with a textile-to-textile recycler. It aims to increase the use of circular materials while cutting reliance on virgin polyester, in line with Primark's stated sustainability objectives.

The two moves point in the same direction — locking in supply through direct agreements and industry consortia, rather than spot-buying recycled inputs as they become available.

What decision does this force for sourcing teams?

For suppliers to Primark, the Denim Deal membership signals that recycled-content specifications in denim orders are set to tighten, not loosen. Mills and garment makers that can deliver post-consumer recycled cotton blends — and design out rivets and stretch fibres that block recyclability — are the ones positioned to benefit as the retailer works to lift that 8% circular-design share.

Compliance teams should treat the Circular Product Standard 2.0 as the traceability benchmark: durability, materials and recyclability are the three criteria against which future denim programmes will be assessed.
