Unveiling The Hidden Environmental Impact Of Microplastics In Handmade Textiles

Everyone is well aware of the environmental pollution and destruction caused by plastic. It has been more than decades of constant social awareness campaigns and inclusion in educational curriculums of “Plastic pollutes the environment”. Although a significant part of society is consciously taking steps to do something about the situation and creating a direct or indirect impact on the environment, most of those people are also unaware of all the forms of plastics to avoid. Fairly educated and consciously part of the population across the globe is unconscious sometimes even without a choice are surrounded by what are called ‘microplastics’. And these are far more dangerous than what the eye perceives. It's the iceberg that penetrated deep into the environment without knowledge or sight of the whole picture.

What are Microplastics?

According to National Geographic, microplastics are really small pieces of plastic, less than five millimetres across, even smaller than a pearl. There are two types: primary, which are made that size for things like cosmetics or come from textiles like clothing, and secondary, which come from bigger plastic items breaking down over time, like water bottles. The issue is, that they don't break down easily and can stick around for hundreds or thousands of years, causing a lot of problems. They end up in the ocean, where animals can eat them, and even in our drinking water.

Microplastics in Textiles

Tiny pieces of plastic, called microplastic fibres or microfibers, come from our clothes when we wash them. These bits are so small that they can easily get into the water. They're a big problem because they add to the pollution in our environment. Scientists have studied how many of these tiny fibres come off our clothes when we do laundry. They found that a lot of fibres can come off each piece of clothing, and it depends on what kind of fabric and detergent we use. Even though places that clean our dirty water try to catch these fibres, many still end up in rivers and oceans. This can be bad for sea animals that eat them accidentally, and it might even be bad for us too. We still need to learn more about these tiny plastic fibres so we can figure out how to stop them from causing harm.

PFAS (Per- and polyfluoroalkyl substances) are a group of man-made chemicals that have been used in various industrial and consumer products for decades due to their water and stain-resistant properties. In recent years, concerns have arisen regarding the presence of PFAS in handmade textiles. While PFAS are commonly associated with products like non-stick cookware, waterproof clothing, and carpets, they can also be found in textiles treated with water or stain repellents. Handmade textiles, including rugs, quilts, and clothing, may inadvertently contain PFAS if they have been treated with these chemical coatings.

This raises concerns about potential exposure to PFAS through direct contact with these textiles, particularly considering the health risks associated with these chemicals, including links to various adverse health effects. As awareness grows, efforts to identify and mitigate PFAS contamination in handmade textiles are becoming increasingly important for ensuring consumer safety and environmental protection

Characteristics of Microfibers

• Microfibers are defined as staple fibres or filaments with a linear density ranging from 0.3 dtex to 1 dtex, with diameters usually less than 10 μm.

• Polyester (PET) and polyamide (PA or Nylon) are the primary types of microfibers widely used in the textile and apparel industry, while other materials like acrylic, viscose, and polypropylene (PP) make up a smaller proportion.

Where does microplastics come from?

Primary Sources

1. Synthetic Textiles: Tiny plastic fibres shed from synthetic clothing during washing contribute significantly to microplastic pollution.

2. Vehicle tyres: When vehicles move, their tyres wear down, releasing microplastics. The European Union alone emits around 0.5 million metric tonnes of microplastics per year from tyre wear.

3. City Dust: Urban areas produce microplastics from various sources such as artificial turf, building paints, and industrial abrasives, contributing to 10-20% of microplastic pollution.

4. Personal Care Products: Microplastics, like microbeads, in products like exfoliants and cosmetics, also add to microplastic pollution, making up 1-2% of the total.

5. Plastic Pellets: These pellets, used in manufacturing plastics, contribute to pollution through accidental losses during handling and production, accounting for 0.3% of microplastic pollution.

Secondary Sources

1. Marine and Terrestrial Waste: Larger plastics like fishing gear and shipping waste break down into smaller microplastics over time, although it's hard to measure their exact contribution.

Statistics on Microplastics and Microfibers

According to a report published on First Sentier MUFG Sustainable Investment Institute

Microplastics and microfibers have been detected in nearly every ecosystem worldwide, spanning from the deep ocean to coastlines, Arctic seawater, freshwater bodies, soil, mountaintops, and even the air. Their presence is extensively documented, especially in marine environments, where they are notably abundant.

• The Indian Ocean contains around 4 billion microfibers per square kilometre of sediment.

• Over 90% of microplastic pollution in Arctic seawater is attributed to synthetic microfibers.

• Polyester emerges as the most prevalent synthetic microfiber type in oceanic environments.

• The Mediterranean Sea, despite its geographical distance from major pollution sources, harbours relatively high concentrations of microfibers, potentially due to its reduced water circulation.

Despite their small size, microplastics pose significant environmental concerns, threatening marine life and ecosystems globally. Efforts to mitigate their impact and prevent further pollution are essential for safeguarding the health of our planet.

Microplastic pollutions

• Microplastic and microfiber pollution projections vary, with estimates suggesting that between 1 to 5.6 million metric tonnes could enter the environment annually, which could account for over 10% of global annual mismanaged plastic waste.

• Global release of microplastics into the ocean is estimated to range from 0.8 to 2.5 million tonnes per year.

• Despite these concerns, microplastic and microfiber pollution remains largely unregulated.

• If not addressed, the growth in textile consumption is expected to worsen the situation, with a potential 54% increase in annual microfiber release into the environment by 2030.

• An additional estimate suggests that around 22 million metric tonnes of synthetic microfibers could enter the environment by 2050.

• Microplastic pollution is also expected to rise due to the increased production of microplastic sources like vehicle tyres and pre-production plastics over the next 15 years.

Fibre Release from Laundry

• According to a recent study, washing 6 kg of laundry could release over 700,000 fibres into the water.

• A previous study reported lower levels of fibre release in wash effluent, estimating approximately 100–300 fibres per litre in outgoing water from washing machines. However, this study lacked detailed information to fully quantify the amount of fibres released and did not use detergent in washing procedures, potentially leading to underestimated values.

The fate of Microplastics in Sewage Treatment Plants

• Effluent from washing often ends up in sewage treatment plants in many countries.

• Studies show that 70–99% of microplastic particles released in sewage effluent can be retained in sludge, with technologies like sand filters or membrane bioreactors playing a role in retention.

• Despite these measures, microplastic fibres are still found in outgoing effluent, with reported levels exceeding 1770 particles per hour or approximately 0.009 particles per litre.
