Girlguiding is the UK's largest youth organisation dedicated to girls, with around 385,000 members. In 2026, following a four-year project shaped by the views of nearly 55,000 girls and volunteers, Girlguiding launched the first full redesign of its uniform in over 30 years - with sustainability built in as a core requirement, not an afterthought.

Working with CTF, Girlguiding certified over half of the new range against our Design for Recyclability criteria: 15 styles worn across all four sections, from Rainbows to Rangers, plus young leaders and adult volunteers, totaling 280,000 garments at launch. Each certified garment carries the Infinitee™ mark, confirming it has been assessed as compatible with existing fibre-to-fibre recycling technologies.

A key part of the assessment was addressing print. Polyurethane-based prints are a common contaminant in fibre-to-fibre recycling, meaning printed garments would previously have been rejected by recyclers or downgraded at end of life. Girlguiding and its supply partners converted every print in the range to water-based alternatives, removing one of the most persistent barriers to recyclability without compromising on print quality.

Uniform ranges are produced at volume, to consistent specifications, over long periods, which means decisions made at the design stage compound year on year. That makes uniform one of the most effective categories in which to embed circular design from the outset.

15 styles. 280,000 garments. Every print in the range reformulated to remove a barrier to recycling.

DHL Supply Chain manages one of the most complex uniform programmes in the UK: 40,000 colleagues, 500 sites, and over 1,800 product SKUs. Scaling sustainability across an operation of that size requires more than good intentions. It requires a standard.

Working with CTF, DHL developed the Together Range: ten recyclable uniform products across 128 SKUs, with an annual volume of approximately 55,000 garments. Each style uses mono-fibre design principles, with every fabric, trim and accessory chosen to enable recyclability. A QR code integrated into each garment guides colleagues through the return and recycling process, with collection boxes available on site.

At end of life, garments are returned and recycled back into rPET chip, which is then spun into yarn or moulded into trims, ready to re-enter the supply chain.

10 products. 128 SKUs. 55,000 garments a year designed to return.

BAM Clothing began their certification journey in Autumn/Winter 2022 with two polyester outerwear styles - 1% of their range. The brief was simple: start somewhere.

What followed was nine seasons of continuous progress. Cotton and wool were added to the certified range in AW23, expanding beyond outerwear into new categories and fibres. By AW24, BAM were certifying 26 styles across three fibre types. By AW25, that had grown to 38. SS26 brought the development of a new waterproof fabric designed from the outset to be recycled, embedding circular thinking at the material innovation stage, not just the design stage.

Today, BAM have certified 172 styles and diverted 124,755 garments from landfill and incineration.

Regatta Professional, part of the Regatta Group, began working with CTF to pursue Infinitee™ certification for a new workwear range designed from the outset to be recycled. The brief was deliberately ambitious: not simply to use recycled materials, but to create garments that could re-enter the materials supply chain at end-of-life.

The result is Recycle.me™, a five-piece uniform collection in 100% polyester mono-fibre, awarded Infinitee™ certification. Designed to meet the requirements of Project Re:claim, the UK's first polyester mechanical recycler built for fibre to fibre recycling, each garment can be returned via a dedicated take back scheme operated by the Salvation Army Trading Company.

5 styles certified and the infrastructure to support it — this is circularity in practice.

David Luke had already been at the forefront of sustainable schoolwear for over a decade, introducing blazers made from recycled plastic bottles as an industry first. But MD Kathryn Shuttleworth recognised that using recycled materials wasn't enough if the garments couldn't be recycled themselves at end of life. The question was what happened next.

Working with CTF from January 2023, David Luke achieved Infinitee™ certification for their Eco Blazer. The style was assessed component by component, from fabric and thread to buttons, interlining and shoulder pads, with design amends enabling its recyclability, without compromising aesthetics or function.

Certified since January 2023 with a ten-year strategy to make school uniform completely circular.
