Microplastics are tiny plastic particles that have become a growing concern for Wollongong, and right across the world. Particles have been found in the ocean, in rainfall, and even within our bodies. As plastic breaks down over time, it releases microplastics and harmful chemicals into the air, water, and soil.
In New South Wales, microplastics are considered the highest priority threat to marine life from whales to plankton, and even the fish we eat.
How do they enter the environment?
Microplastics can enter our environment in several ways:
- Through household wastewater - products like cosmetics, cleaning agents, and synthetic clothing release microplastics when washed down the drain,
- From synthetic textiles - every time we wash clothes made from polyester, nylon, or acrylic, microplastic fibres (called microfibres) are shed and enter our wastewater systems, and
- Via primary microplastics - these are intentionally manufactured small plastic particles, such as microbeads, that are released directly into the environment.
Globally, the release of primary microplastics into the ocean is equivalent to every person throwing one plastic bag into the ocean each week, and around 35% of this comes from laundering synthetic textiles.
How can I help reduce microplastics?
There are plenty of easy and practical steps you can take to reduce microplastics at home.
Washing machine solutions
- Install a filter - inline or drum filters with high capture rates can trap microfibers before they enter wastewater,
- Use mesh bags or drum covers - these can help contain fibres during the wash cycle,
- Try laundry balls - choose eco-friendly options that help reduce fibre shedding.
Everyday habits
- Wash less often - airing clothes between wears can reduce the need for frequent washing,
- Use cold water - cold cycles shed fewer microfibers than hot ones,
- Wash full loads - this reduces water usage and fibre release,
- Use less detergent - excess detergent can increase fibre shedding,
- Choose natural fabrics - linen, cotton, hemp, and wool shed fewer microplastics,
- Turn clothes inside out - this can reduce fibre loss,
- Air dry your clothes - clotheslines are gentler than dryers,
- Opt for front-loading machines - these release fewer microfibres than top-loaders.
