What You'll Learn
Polyester is a type of plastic
As a plastic, polyester contributes to the global crisis of plastic pollution. It ends up in landfills, and when washed, polyester clothing releases microplastics into the water, which are ingested by marine life, leading to physical and chemical harm. These microplastics have been found in the deepest ocean trenches and remote Arctic ice, posing a severe threat to marine ecosystems and potentially entering the human food chain through seafood consumption.
The production and disposal of polyester also have environmental implications. While recycled polyester, made from waste materials such as plastic bottles, is considered more sustainable than virgin polyester, it still requires chemicals and energy, leading to negative environmental impacts. Additionally, the quality of recycled polyester fibres is generally lower, limiting their use to specific products.
Polyester clothing has been linked to health risks, including skin irritation and chemical exposure. The synthetic material traps heat and holds onto odours, and the presence of microplastics shed by polyester garments has been detected in human blood, placenta, and baby faeces. These microplastics enter the body through ingestion and inhalation, with potential unknown long-term effects.
While polyester provides durability and ease of use, its plastic nature and associated environmental and health concerns have sparked a movement towards more sustainable and natural alternatives in the fashion industry. Consumers are increasingly seeking clothing made from natural fibres, and brands are exploring alternative materials and designs to reduce their reliance on polyester and other plastics.

Recycled polyester
Polyester is a synthetic fabric derived from polyethylene terephthalate (PET), a type of thermoplastic polyester. It is widely used in clothing due to its lightweight, durable, and quick-drying properties, especially in athletic and outdoor wear. However, the environmental and health impacts of polyester have come under scrutiny in recent years.
However, it is important to note that recycled polyester is not without its drawbacks. The mechanical recycling process, which involves shredding and melting the polyester, results in lower-quality fibres that may require blending with virgin polyester. Additionally, the issue of microplastics remains a concern, as washing recycled polyester garments can release microscopic plastic fibres into the environment, contributing to water pollution and potentially entering the human food chain through seafood consumption.
To address the challenges associated with recycled polyester, some brands are exploring textile-to-textile recycling, aiming for circularity in fashion. For example, H&M Group is collaborating with Syre to develop textile-to-textile recycled polyester, and initiatives like Accelerating Circularity have launched databases for commercially available recycled polyester. These efforts demonstrate a commitment to reducing the fashion industry's environmental footprint and promoting sustainability.
While recycled polyester may not be a perfect solution, it offers a more sustainable alternative to virgin polyester by reducing waste, lowering energy consumption, and decreasing the reliance on non-renewable resources.

Environmental impact of polyester
Polyester is a synthetic material derived from oil, also known as petroleum. It is the most widely used clothing fibre in the world, accounting for roughly half of the overall fibre market and around 80% of synthetic fibres. Its popularity stems from its durability, versatility, and relatively low cost of production. However, the environmental impact of polyester is significant, and its production and disposal have led the fashion industry to explore more sustainable alternatives.
One of the primary environmental concerns regarding polyester is the issue of microfibres. When polyester clothing is washed, microfibres are shed and enter water bodies, affecting marine life and ultimately ending up in the bodies of animals, marine life, and humans. It is estimated that 0.5 million tonnes of plastic microfibres are shed annually during the washing of textiles made from plastics like polyester, with this figure potentially reaching 0.7 million tonnes by 2050. The accumulation of these microfibres in the ocean poses a significant threat to marine ecosystems.
The production of polyester also has a substantial environmental impact. It requires a significant amount of energy, resulting in the emission of greenhouse gases, specifically 27.2 kg of CO2 equivalent per kg of polyester woven fabric. The extraction and refinement of crude oil, the primary raw material for polyester, consume energy and disrupt the surrounding ecosystem. Additionally, the dyeing and finishing processes in polyester fabric production are ranked first in terms of environmental unsustainability due to their impact on climate change, water use, depletion of resources, ecosystem quality, and human health. The chemicals used in these processes, such as heavy metals, formaldehyde, and aromatic amines, can be toxic, carcinogenic, or otherwise harmful to human health and the environment.
The social impact of polyester production cannot be overlooked either. The high cost and time pressures imposed on the supply chain can lead to poor working conditions, long hours, and low pay for garment workers. There have also been reports of modern slavery and child labour in some instances. Additionally, workers are often exposed to hazardous processes, substances, and unsafe buildings or lack the necessary safety equipment, putting their health and safety at risk.
The environmental impact of polyester has led to a growing movement towards recycled polyester and alternative materials. Recycled polyester is now as cheap as virgin polyester, and innovations in textile recycling technology are showing promise. However, the current lack of a robust global infrastructure for collecting, sorting, and recycling used polyester garments remains a significant barrier to achieving higher recycling rates.

Health risks of wearing polyester
Polyester is a synthetic woven material derived from petroleum, also known as polyethylene terephthalate (PET), a type of thermoplastic polyester. It is one of the most popular materials in the modern age, accounting for roughly half of the overall fibre market and around 80% of synthetic fibres.
While polyester is durable, lightweight, and quick-drying, making it a popular choice for athletic and outdoor wear, it does come with several health risks. Firstly, it is not hypoallergenic or breathable, which can contribute to skin problems such as dermatitis, acne, itching, and redness. Individuals with sensitive skin may be at an increased risk of rashes and irritation.
Secondly, polyester clothing can release traces of antimony when exposed to higher temperatures, such as when put in the dryer or when the wearer sweats. Antimony is used in the production process as a catalyst to produce PET, and exposure to this chemical can impact the heart, lungs, and stomach, as well as irritate the eyes. However, it is important to note that the levels of exposure from wearing polyester clothing are relatively minimal and can be further decreased by washing the clothing before use.
Additionally, the presence of microplastics in the environment is a growing concern. Polyester clothing sheds microplastics, especially during washing, which can then pass through filtration systems and enter natural water bodies. These microplastics are ingested by marine life and can accumulate in the food chain, potentially impacting human health through seafood consumption. The surface of microplastics can also host bacteria and viruses, further threatening human health.
Lastly, the chemicals used in the production of polyester clothing can pose health risks to wearers. Formaldehyde and other perfluorochemicals (PFCs) released from polyester have been linked to lung problems, headaches, and autoimmune diseases. The dyeing process can expose workers to hazardous chemicals, and these chemicals can remain in the final product, potentially impacting the health of individuals wearing the garments over time.
Overall, while polyester may offer convenience and durability, it is important to be aware of the potential health risks associated with this material and make informed choices when it comes to the clothing we wear.

Microplastics pollution from polyester
Polyester is a type of plastic derived from a polymer called polyethylene terephthalate (PET), a thermoplastic polyester. It is a commonly used fabric in clothing, upholstery, carpets, and other materials due to its lightweight, durable, and quick-drying properties. However, the use of polyester contributes significantly to microplastics pollution, causing environmental and health concerns.
Microplastics are tiny plastic particles less than 5 mm in size. They are released into the environment during the production and cleaning of polyester fabrics. During the washing of polyester clothing, microfibers are stripped and carried off by friction and turbulence in the washing machine, eventually ending up in wastewater and the natural environment. Standard wastewater treatment plants are not designed to effectively capture and remove these microplastics, leading to their accumulation in oceans and other water bodies.
The presence of microplastics in the marine environment is a growing concern, as they can be ingested by marine life, leading to physical and chemical harm. Studies have found microplastics in the deepest ocean trenches and remote Arctic ice, indicating their widespread impact on marine ecosystems. The potential entry of these microplastics into the human food chain through seafood consumption is also a worrying prospect.
To address the issue of microplastics pollution from polyester, some solutions have been proposed:
- Using recycled polyester: Recycled polyester, made from post-consumer plastic like water bottles, is considered more sustainable than virgin polyester as it reduces the need for new polyester production from petroleum. However, the recycling process has limitations and can still have negative environmental impacts.
- Choosing natural fibers: Consumers can opt for clothing made with natural fibers instead of polyester whenever possible. However, it is important to note that even "100% natural" clothing can contain chemical additives, and the switch to natural fibers may not be a comprehensive solution to the problem.
- Microfiber filters: Installing microfiber filters in washing machines can help capture microplastics before they enter the wastewater stream. Products like the Guppyfriend laundry bag and the Cora Ball are designed to keep microplastics out of wastewater.
- Extended clothing use: Reducing the consumption of new clothing and extending the lifespan of existing garments can help decrease the release of microplastics into the environment.
