Merino wool does not release microplastics into oceans, new study finds

Ground-breaking new research from The Woolmark Company has found that Merino wool does not contribute to the issue of microplastics in our oceans.

The scientific study - titled Microfibre Pollution and the Marine Biodegradation of Wool - has found that both untreated and machine washable wool readily biodegrade in marine environments, while synthetic fibres do not. The study also found the machine washable wool actually biodegrades at a faster rate than untreated wool fabrics and there was no evidence the treated wool’s polyamide resin coating added to microplastic pollution.

Previous estimates suggest as much as 20 per cent to 35 per cent of all primary source microplastics in the marine environment are from the use of synthetic clothing and a single polyester fleece garment can produce more than 1900 microfibres per wash.

In this latest study researchers compared the biodegradability of the two types of Merino wool in sea water to the biodegradability of viscose rayon, polyester, nylon and polypropylene. Residues were examined using scanning electron microscopy and energy-dispersive X-ray spectroscopy. All fabrics were washed repeatedly before testing to simulate a partial garment lifetime. The rate of biodegradation was then compared to that of a substance known to biodegrade readily, kraft paper pulp.

Scientists found untreated wool biodegraded at 20.3 per cent the rate of the pulp and the machine-washable wool biodegraded more than three times as quickly, at a rate of 67.3 per cent – the fastest of all fabrics.

At the tail-end was Nylon, biodegrading at a rate of just 0.8 percent, followed by polypropylene and polyester.

“Our research into wool and microplastics began back in 2016 when we investigated the current state of knowledge concerning microplastic pollution, focussing on microfibres from textiles,” explains The Woolmark Company Managing Director Stuart McCullough. “This initial body of research began the process of improving methodological development to account for microfibre release during the use phase in the Lifecycle Assessment of clothing.

“This latest scientific study is a significant addition to the body of research investigating the damage certain textiles cause to our environment. Wool has long been heralded the original eco fibre, but concerns had been raised about the machine-washable finish applied to wool and whether it added to the microplastic problem, so we wanted to clarify that issue. During these ever-changing troubled times it’s important to consider how well-intentioned consumers can make purchasing decisions that help look after the health of the environment. Choosing natural fibres, such as Merino wool is an important place to start.”

Merino wool moves into China’s high-performance sportswear market

China’s leading sportswear brands are beginning to treat Merino wool not as a lifestyle material, but as a performance input as natural fibres move from the margins of sportswear into elite technical applications. That shift is increasingly evident in the material strategies of major domestic groups such as ANTA.

Aid by Trade Foundation presents annual report for 2025: Market position and impact of sustainably verified natural fibres strengthened

Despite global supply chain challenges, the Aid by Trade Foundation (AbTF) was able to further expand its international role in promoting sustainably verified natural fibres in 2025. In doing so, the foundation remains true to its fundamental approach of leveraging market forces. Last year, it generated total revenues of EUR 7.8 million; this included EUR 6.7 million collected through the successful marketing of four standards: Cotton made in Africa (CmiA), CmiA Organic, The Good Cashmere Standard (GCS), and the Regenerative Cotton Standard (RCS). AbTF invested the resulting income in projects aiming to protect biodiversity, support women, increase transparency in the textile supply chain, and implement its verification system.
