Tips for Reducing Laundry Microplastics

Posted on 05/01/2025

As awareness of environmental issues grows, more attention has been placed on the impact of microplastics. Microplastics are tiny plastic particles less than 5mm in diameter. They pose significant threats to marine life and eventually, to human health as they enter the food chain. One major source of microplastics is synthetic fabrics used in clothing. Each time you wash synthetic clothes, tiny fibers break off and make their way into wastewater systems, eventually reaching oceans and other water bodies. Fortunately, there are practical steps you can take to reduce the amount of laundry-related microplastics.

1. Understanding Microplastics

Microplastics originate from a variety of sources, including cosmetics, industrial processes, and most notably, synthetic textiles such as nylon, polyester, and acrylic. When these materials are washed, friction breaks down the fibers into microscopic pieces that are too small to be filtered out by wastewater treatment plants. This converts our oceans into reservoirs of plastic, threatening marine life and potentially impacting human health through the food chain.

2. Opt for Natural Fibers

One of the most effective ways to cut down on microplastic pollution is by choosing natural fibers such as cotton, wool, silk, and hemp. These materials do not release microplastics when washed and biodegrade more easily in natural environments. While natural fibers can be more expensive, investing in durable, high-quality garments can save you money in the long run and help the environment.

3. Use a Microplastic Filter

There are several types of filters available that can capture microplastics before they are released into wastewater. Inline filters can be installed in washing machines, and there are also external filter bags that collect fibers during the wash cycle. Products like the Guppyfriend washing bag or Cora Ball are designed to reduce the amount of microplastics released by acting as an intermediary between your clothes and the washing machine.

4. Wash Clothes Less Frequently

Washing clothes less frequently can significantly reduce the release of microplastics. Not all garments need to be washed after every wear. Items like jeans and jackets can be worn several times before needing a wash, especially if they're spot-cleaned or aired out between wears. By reducing the frequency of washing, you also conserve water and energy.

5. Use Cold Water

Using cold water in your washes can help reduce the shedding of microfibers. Hot water can cause fabrics to break down more quickly, leading to a greater release of fibers. Cold water is also more energy-efficient, making it a win-win for both your wallet and the environment.

6. Optimize Detergent Use

Using the right amount of detergent is crucial. Overuse of detergent can lead to more friction during the washing cycle, which in turn leads to more fibers breaking off garments. Moreover, eco-friendly detergents are formulated to be effective in lower dosages and at lower temperatures, which helps to minimize fabric damage.

7. Avoid Fast Fashion

Fast fashion is notorious for producing low-quality garments that degrade quickly and release more microplastics when washed. Instead, invest in high-quality, durable clothing options. Brands that prioritize sustainability often use better materials and practices, making their garments last longer and shed fewer fibers.

8. Fill Up Your Washing Machine

Filling your washing machine to its capacity can reduce friction between the clothes and the machine's drum, thereby reducing the breakdown of fibers. However, be careful not to overload the machine, as this can strain the motor and lead to inefficient washing.

9. Line Dry Whenever Possible

Using a dryer can lead to additional microfiber release. Line drying not only conserves electricity but also reduces fiber breakage. If line drying isn't possible, consider using a dryer ball, which can help mitigate fiber shedding.

10. Support Research and Legislation

Microplastic pollution is a global issue that requires collective action. Supporting research initiatives and backing policies aimed at reducing microplastic pollution can help mitigate the problem on a larger scale. For instance, supporting brands and initiatives that focus on recycling and sustainable practices can contribute to a reduction in microplastic release.

11. Regular Maintenance of Washing Machines

Regular maintenance of your washing machine is essential for efficient performance. Cleaning the filter trap regularly and running periodic maintenance washes can help in capturing and removing some of the fibers that would otherwise escape into wastewater.

12. Educate Others

Raising awareness about the dangers of microplastics and ways to reduce them is essential for collective action. Sharing information and tips with friends, family, and communities can lead to more widespread adoption of better practices, amplifying the positive impact.

Conclusion

Microplastic pollution is a pressing issue that requires both individual and collective efforts to mitigate. From opting for natural fibers and using microplastic filters to being mindful of washing practices, there are numerous ways to reduce your contribution to this environmental problem. By making small yet significant changes in your laundry routine, you can help protect marine life, conserve natural resources, and contribute to a healthier planet.

As consumers become more environmentally conscious, the demand for sustainable solutions will hopefully drive further innovations and regulations aimed at curbing microplastic pollution. Until then, every step you take matters. Every microplastic fiber kept out of our waterways represents a step towards cleaner oceans and a healthier ecosystem.
