What You'll Learn
Polyester is a type of plastic
Polyester is a synthetic fabric that is derived from a category of polymers called polyethylene terephthalate (PET). PET is a type of thermoplastic polyester, which means it can be moulded when heated and then retains its shape when cooled. This is why polyester clothing is lightweight, durable, and quick-drying, making it a popular choice for athletic and outdoor wear.
Polyester is one of the most common fabrics used in clothing today, but it is important to consider its environmental impact. Polyester is a major contributor to plastic pollution, as it does not break down easily and can shed microfibres when worn, touched, or washed. These microfibres can end up in our oceans and other water sources, contributing to the growing problem of microplastic pollution.
Additionally, the production and disposal of polyester clothing can have negative consequences for the environment. While recycled polyester, made from post-consumer plastic like water bottles, is often seen as a more sustainable option, it still has environmental costs. The recycling process consumes energy and resources, and the quality of the polyester can degrade with each cycle, limiting its usability over time.
Furthermore, there are health risks associated with wearing polyester clothing. Microplastics inside the human body have been linked to various health concerns, and polyester is a significant contributor to microplastic contamination. Studies have shown that polyester sheds more microplastics than any other material, making up a large portion of microplastic pollution in the Arctic and household dust.
Overall, while polyester has its benefits in terms of durability and ease of use, it is important to recognize its impact on the environment and human health. As consumers, we should be aware of the potential consequences of purchasing and wearing polyester clothing and consider more sustainable and natural alternatives whenever possible.

Environmental impact of polyester
Polyester is a synthetic fibre derived from oil and is the world's most commonly used fibre. It is light, strong, wrinkle-resistant, and can be woven or knitted. It is also easily blended with other fibres and is used in a wide range of applications, from clothing to backpacks and bags. However, its environmental impact is significant and far-reaching.
Firstly, the production of polyester is energy-intensive and highly polluting. The process of extracting crude oil and refining it into the building blocks of polyester, or polyethylene terephthalate (PET), consumes energy and disrupts the surrounding ecosystem. It also releases harmful toxins and greenhouse gases, contributing to climate change. The dyeing and finishing processes are particularly unsustainable, as they use toxic chemicals that can adversely affect human health and the environment. These chemicals, such as heavy metals, formaldehyde, and aromatic amines, can cause skin disorders, respiratory issues, and even cancer in workers exposed to them.
Secondly, the use of polyester contributes to the growing problem of microplastic pollution. When polyester clothing is washed, it sheds microfibres that enter water bodies and affect marine life. These microfibres can also end up in our food and water supply, potentially impacting human health. According to the Ellen Macarthur Foundation, an estimated 0.5 million tonnes of plastic microfibres are shed annually during the washing of textiles, and this number may increase to 0.7 million tonnes by 2050. The accumulated amount entering the ocean between 2015 and 2050 could exceed 22 million tonnes. Additionally, 75% of fish caught at mid-ocean depths in the Northwest Atlantic have been found to contain microplastics in their stomachs.
Thirdly, the disposal of polyester is an environmental concern. As polyester is made from plastic, it is non-biodegradable and can take hundreds of years to decompose. When sent to landfills, the toxic materials used in production can leach into the soil and contaminate water sources. While polyester can be recycled, the current lack of a robust global infrastructure for collecting, sorting, and recycling used polyester garments hinders higher recycling rates.
Lastly, the social impact of polyester production cannot be overlooked. Workers in the polyester supply chain often face poor working conditions, long hours, and low pay. There is also evidence of modern slavery and child labour in some instances. The high cost and time pressures imposed on garment producers can lead to dangerous working environments, with hazardous processes and substances used during production.
In conclusion, despite its widespread use, polyester has significant environmental and social impacts throughout its life cycle, from production and use to disposal. To mitigate these impacts, the fashion industry is exploring more sustainable alternatives, such as recycled fibres, and advocating for a reduction in fossil fuel usage and overproduction.

Health concerns related to polyester
Polyester is a type of plastic derived from a category of polymers known as polyethylene terephthalate (PET). It is a synthetic woven material that is lightweight, durable, and quick-drying, making it a popular choice for clothing, especially athletic and outdoor wear. However, its widespread use has led to significant environmental and health concerns.
One of the primary health concerns related to polyester is its impact on skin health. Polyester is neither hypoallergenic nor breathable, which can contribute to various skin problems. Wearing polyester clothing has been associated with increased flare-ups of skin conditions such as dermatitis and acne, as well as itching, redness, and irritation. The non-breathable nature of polyester can also cause discomfort and make it difficult for the skin to regulate temperature effectively.
The production and treatment of polyester fabric also involve the use of toxic chemicals, which can pose risks to both workers and consumers. Formaldehyde, for example, is used to make clothing wrinkle-free and help dyes stick to fabrics. However, formaldehyde exposure has been linked to serious health issues, including skin irritation, allergy and asthma flare-ups, and, in the long term, certain types of cancer, such as leukaemia. Other chemicals used in the dyeing process, such as heavy metals and aromatic amines, can also be harmful to human health, leading to skin disorders, respiratory issues, and, in severe cases, life-threatening diseases.
The release of microplastics from polyester clothing is another significant health concern. When polyester garments are washed, they shed microplastic particles that can enter water systems and the environment. These microplastics have been linked to various health issues in humans, including inflammation, oxidative stress, and potential DNA damage. Additionally, the surface of microplastics can harbour bacteria and viruses, further contributing to health risks.
Lastly, the environmental impact of polyester production and disposal cannot be overlooked. Polyester is derived from crude oil, and its production contributes to greenhouse gas emissions, water and land pollution, and the unsustainable depletion of resources. The textile industry's high water consumption and emissions contribute to pollution, endangering human health and affecting ecosystems. While recycled polyester from plastic bottles can help reduce the environmental impact of virgin polyester production, it does not solve the fast fashion problem entirely. The recycling process consumes energy and resources, and the quality of recycled polyester can degrade with each cycle, limiting its long-term usability.

Recycled polyester
Polyester is a type of plastic derived from a category of polymers known as polyethylene terephthalate (PET). This is the same material used to make plastic water bottles. Polyester clothing is popular due to its lightweight, durable, and quick-drying properties. However, it has significant environmental and health impacts, including microplastic pollution and skin irritation.
The recycled polyester market is growing due to its affordability, versatility, high strength, ease of stretching, recyclability, elasticity, and resistance to abrasion, wrinkles, and fungus. It is widely used in the textile industry, especially for sportswear and technical textiles, because of its smooth texture and durability. Major brands such as Adidas, Patagonia, and H&M Group are committing to using recycled polyester in their products, demonstrating a shift towards circularity in fashion.
However, recycled polyester is not without its challenges. It is a form of downcycling, and the recycled fibres may only be suitable for specific products like insulation, carpets, or non-woven fabrics. Mechanical recycling, which involves shredding, melting, and reforming plastic, degrades the fibre's strength over time, often requiring the addition of virgin polyester. Chemical recycling, which restores polyester to its original monomer state, is more expensive and less widely used. Additionally, recycled polyester clothing can still contribute to microplastic pollution during washing, although this can be mitigated by using filter washing bags.

Polyester microfibres and microplastics
Polyester is a type of plastic derived from a category of polymers known as polyethylene terephthalate (PET). This is the same material used to make ubiquitous plastic bottles. Polyester is one of the most common fabrics used in clothing today, known for being lightweight, durable, and quick-drying. However, it has significant environmental and health impacts.
Polyester clothing is a major contributor to the global crisis of plastic pollution. When washed, polyester clothing releases plastic microfibers—tiny polyester and acrylic threads—into the water. These microfibers are then released into sewers, seas, and oceans, contributing to microplastic pollution. Scientists estimate that textiles produce 35% of the microplastic pollution in the world's oceans, making them the largest known source of marine microplastic pollution.
The release of microfibers from polyester clothing occurs during washing and everyday use. Studies have found that wastewater from laundry and industrial processes contains microplastics and microfibers. These microfibers can have harmful effects on the environment, including the soil and aquatic ecosystems.
To address the problem of microfiber pollution, some products claim to keep microplastics out of wastewater when washing clothes. For example, the Guppyfriend laundry bag and the Cora Ball are designed to capture microplastics during the washing process. Additionally, using natural fibers instead of synthetic fibers like polyester and nylon can help reduce microfiber pollution.
While recycled polyester, made from post-consumer plastic like water bottles, is often considered a more sustainable option, it does not solve all the challenges associated with polyester. The recycling process consumes energy and resources, and the quality of polyester can degrade with each recycling cycle. Therefore, a holistic approach is needed to address the environmental and health impacts of polyester.
