How Bad is Polyester for the Planet?
Polyester, once hailed as a “wonder fiber” in the 1950s, remains a favorite in the fashion industry thanks to its durability, versatility, and low cost. This synthetic fiber is known for its resistance to shrinking, stretching, and wrinkling, making it incredibly convenient for everyday wear. It can mimic the appearance and texture of silk, cotton, wool, or linen, and when blended with other fibers, it adds durability and strength to garments. However, behind polyester’s convenience and affordability lies a troubling environmental impact.
The Dark Side of Polyester
Polyester is made from petroleum, a non-renewable resource, making it a carbon-intensive material. Over 70 million barrels of oil are used annually to produce polyester, contributing significantly to global carbon emissions. As a synthetic fiber, polyester is also non-biodegradable, meaning it can take centuries to break down, adding to the growing issue of landfill waste.
But that’s not the worst part—when polyester garments are washed, they release tiny plastic particles, known as microfibers, into the water supply. These microfibers eventually make their way into rivers, oceans, and marine life, contributing to the escalating problem of plastic pollution. In fact, synthetic garments are one of the largest sources of microplastic pollution in the oceans, with up to 1,900 fibers shedding from a single garment with each wash.
Additionally, polyester production requires harmful chemicals, some of which are carcinogenic. These chemicals are often released untreated into the environment, especially in countries with lax environmental regulations like China, Indonesia, and Bangladesh. The dyeing process for polyester also involves toxic substances, further contaminating water supplies.
Can Polyester Be Sustainable?
Despite its environmental pitfalls, polyester does have a redeeming quality—it’s recyclable. Polyester can be made from recycled plastics, including plastic bottles, reducing the need for virgin petroleum. Recycled polyester is becoming more popular in sustainable fashion, with brands like Stella McCartney using it in their collections for activewear, shoes, and rainwear. Some producers also recycle old polyester garments to create new ones, although this practice isn’t yet widespread.
To make more sustainable choices when purchasing polyester, look for certifications like BLUESIGN and Cradle to Cradle Certified™, which ensure that the manufacturing processes adhere to environmental and safety standards. Opt for recycled polyester when buying rainwear or activewear, and always prioritize natural fibers over synthetic ones whenever possible.
Key Takeaway
If you already own polyester garments, consider recycling them instead of discarding them in the trash. More recycling programs are emerging, allowing polyester to be repurposed rather than ending up in landfills. Additionally, using a microfiber-catching laundry bag when washing polyester can help reduce the amount of microplastics released into the water.
While polyester offers many practical benefits, its environmental impact is significant. Opt for recycled polyester when necessary, but aim to choose natural fibers whenever possible. With mindful consumption, we can reduce the negative impact of polyester on our planet.
