Oman today_ A new study shows that using recycled polyester in the fashion industry, contrary to popular belief, can actually increase microplastic pollution. This material, long promoted as an eco-friendly option, is now being identified by researchers as a significant contributor to environmental contamination.
Many major clothing brands, including H&M, Adidas, and Nike, have shifted a large portion of their production from virgin polyester to recycled polyester, presenting this change as a commitment to sustainability. Most recycled polyester is made from plastic bottles, and brands market it as a way to reduce plastic waste.
However, research conducted by the Changing Markets Foundation in collaboration with Çukurova University indicates that garments made from recycled polyester release, on average, 55% more microplastic fibers during washing than those made from virgin polyester. Additionally, these fibers are smaller, making them easier to disperse in the environment and potentially more harmful.
The study examined clothing from several major brands and found significant differences in pollution levels. Some brands, particularly in their polyester products, released far more microplastic fibers, and in some cases, there were doubts about whether the materials labeled as “recycled” were genuinely recycled.
Researchers and environmental advocates argue that promoting recycled polyester as a green solution is largely misleading. The core problem—fashion’s reliance on synthetic fibers—remains unresolved. They stress that without reducing the production of these materials and preventing the conversion of plastic into short-lived clothing, the microplastic crisis cannot be solved.
Some brands have responded by stating they are investing in technologies to reduce fiber shedding and improve manufacturing processes. Critics, however, emphasize that these measures will not be sufficient as long as widespread use of synthetic fibers continues.
