Fighting Microfiber Pollution

Microfibers are microscopic particles, often made of plastic, that clothing sheds when it is made, worn and laundered. Clothing releases about 120,000 metric tons of microfibers each year. Even natural fibers such as cotton and wool contribute to this pollution if they have been treated with dye, softeners or finishes.

Microfibers are the most common type of microplastic found in nature and inside the human body. If left unchecked, microfiber emissions from the textile industry could triple by 2050. And once in the environment, microfibers are almost impossible to remove.

But there is good news! A myriad of effective solutions already exist that can significantly reduce microfiber emissions during the manufacturing process and across the lifecycle of clothing. These solutions include, but are not limited to:

• Filtration technology in textile mills

• Material and design innovations that reduce shedding, informed by new testing methodologies

• Production and manufacturing changes that reduce fiber loss

These solutions also offer many co-benefits, such as water savings, cost reductions and the creation of more durable materials. Already, major brands are working with The Nature Conservancy (TNC) to implement these measures. Read on for more information about the proven technology available, and stay tuned for a public announcement in early 2026.

Reducing Microfiber Pollution: An Industry Playbook

This playbook offers a set of science-based, cost-effective and easily actionable resources for brands. Developed by The 5 Gyres Institute and The Nature Conservancy, these three guides provide practical strategies for implementing solutions in the manufacturing processes, when sourcing materials and in design. Each guide is designed to support implementation of easy wins—proven strategies that don’t require perfect data or regulatory pressure to begin.

We've seen industries rise to meet the moment before, adopting science-based solutions to solve massive environmental crises. By stopping the use of DDT, the agricultural industry saved countless species of wildlife, including the bald eagle. By phasing out certain chemicals, manufacturers were able to reverse the hole in the ozone layer.

It’s time for another massive win. Clothing brands have the opportunity to reduce global microfiber pollution by as much as 80%.

The apparel sector has a proven track record of tackling complex sustainability challenges—addressing microfiber pollution is no different. This problem was created within a generation, and we believe it can be solved even more rapidly by setting clear, actionable public goals that align with the scale of the challenge. Achieving this requires tools and resources that guide and facilitate scaled action—now readily available—as well as a commitment to transparency and collective action.  

The path forward is clear. Now, it’s time to act.
