Titled "Reducing Microfiber Pollution: An Industry Playbook", the playbook offers a collection of scientifically grounded, cost-effective strategies that can be readily integrated into brand operations to minimise the release of microfibres.

Microfibres, which are minuscule particles that detach from clothing during various stages such as washing, production, wear, drying, and disposal, represent a notable source of pollution. They affect oceans, agricultural lands, wildlife, air quality, drinking water, and even human health.

The 5 Gyres Institute science & innovation director Dr Lisa Erdle said: “Mostly invisible to the eye but widespread in our ecosystems, microfibre pollution is an emerging environmental challenge, and something we’ve seen the fashion industry grapple with.

“Our guides provide brands with the practical, science-backed tools they need to take immediate and effective actions that have a big impact in reducing microfibre shedding.”

The guides provide a suite of practical solutions for brands to implement throughout the textile supply chain. This includes guidance on garment design, material sourcing, and manufacturing processes.

Audience-specific guides in the playbook

Design Solutions: Targets designers and developers and offers alternatives for fibres, yarns, and construction methods.

Sourcing Practices: Directed at sourcing professionals and provides tools for supplier engagement and recommendations for material libraries.

Manufacturing Interventions: Caters to production teams with suggestions on filtration enhancements and washing and finishing techniques.

The Nature Conservancy plastic project director Patrick Journey said: “The main barrier to addressing microfibre pollution is that brands, designers, and suppliers aren’t always aware of the many solutions that can be implemented. These guides shed light on the key levers for impact, which, if scaled across the industry, could turn the tide on this growing conservation crisis.”
