Filtering microfibers from our clothing
Understanding the life cycle of these microfibers, their filtration, retention of plastic micro-particles, and ways to minimize their impact is crucial to mitigate the effects of this insidious form of pollution.
These tiny fragments of synthetic material, often derived from textiles such as polyester, nylon, or acrylic, find their way into our rivers and oceans, contributing to an invisible yet harmful pollution. These materials are valued for their durability, lightness, and strength, but their environmental impact, especially when in contact with water, is concerning. When we wash clothes made of polyester, nylon, or acrylic, small particles of these materials detach as microfibers. These microfibers can be so small that they escape the filtration systems of sewage treatment plants, making their way into water bodies, and ultimately into the oceans.
Once in the oceans, microfibers can have devastating consequences. The seas worldwide have become reservoirs of microplastics, with alarming estimates of nearly 250 billion fragments in the Mediterranean alone. These microfibers degrade very slowly, and their concentration continues to increase. Currently, they account for about 80% of marine waste, a figure that raises growing concerns about its implications for marine biodiversity and human health.
Washing machines play a significant role in releasing microfibers into the water. Aggressive washing cycles, combined with powerful detergents, cause the detachment and release of these microfibers.
However, consumers can also contribute to alleviating this issue. Simple actions such as washing clothes at a maximum temperature of 30°C, using liquid detergent instead of powder (which tends to act as an abrasive agent), and avoiding the use of a tumble dryer can reduce the release of microfibers. Additionally, adopting a minimalist approach to washing by reducing the frequency of clothes washing can also help limit the discharge of microfibers into aquatic ecosystems.
In conclusion, the issue of microfibers in water poses a major environmental challenge. Understanding the sources, dispersion pathways, as well as filtration and retention methods for these particles becomes imperative to combat this form of pollution. By changing our consumption behaviors, adopting more environmentally friendly technologies, and raising awareness among the public, we can hope to reduce the impact of microfibers on our precious aquatic ecosystems.
As a filtration professional, we adhere to emerging technologies aimed at addressing this problem, including the development of filters integrated into washing machines to capture these particles before they are discharged into sewers. We will keep you updated on our developments.
