Polyester dominates the textile industry, making up 59% of it and overshadowing cotton. Despite its popularity, this fast fashion staple has a troubling origin—it’s derived from petroleum and natural gas, significantly contributing to the 7.5% rise in greenhouse gas emissions in 2023. Worse yet, polyester’s plastic microfibers are infiltrating our environment and bodies, heightening the risk of heart disease. It’s a fashion choice with a heavy environmental cost.
While brands like Eileen Fisher and Everlane are moving away from polyester, giants like Shein continue to embrace it. With an estimated annual revenue of $40 billion, the allure of polyester remains strong. Future Market Insights predicts the polyester market will grow from $135.6 billion in 2025 to $210.6 billion by 2035. Lux Research analyst Marcian Lee notes that as long as companies mass-produce, consumers will favor cheap trends over sustainability.
Polyester and Overproduction: A Toxic Partnership
Massive piles of discarded clothing visible from space highlight the industry’s wastefulness. Cheap polyester fuels overproduction, fitting perfectly with planned obsolescence business models. Companies like Shein can release thousands of new items weekly, destined for landfills or incinerators. This lack of transparency complicates climate accountability efforts. Few brands truly evaluate their production levels before attempting to reduce their carbon footprint.
Recycling Polyester: A Pipe Dream?
Over 110 companies, including Adidas, Patagonia, and Nike, have pledged to use only recycled polyester by the end of 2025, yet only 26% are succeeding. Most recycled polyester comes from plastic bottles, a choice circular economy advocates prefer for closed-loop recycling systems. However, the Changing Markets Foundation warns that recycled polyester from bottles releases 55% more microfibers than virgin polyester. It’s progress, but not a complete solution.
Ultimately, polyester remains a favored choice in the fashion industry despite its severe environmental impacts. While initiatives to recycle and reduce its use are increasing, the numbers indicate a long road ahead. This raises questions about the industry’s genuine commitment to change.
