Elastane, also known as Spandex or Lycra®, is the unseen, unsung hero of the modern wardrobe. This remarkable fiber gives our clothes their stretch, comfort, and freedom of movement. It has revolutionized our garments, but this powerful performance comes with a significant hidden cost to the environment.

At Circular People, we believe in being open about the full impact of materials. We want you to know that we discourage virgin elastane and prefer recycled and biodegradable bio-based options. We are actively researching new developments in bio-based and biodegradable elastane, as this is a hot topic for innovation. Here is what you need to know about the current landscape.

The Problem with Elastane

• It’s a Plastic: Elastane is a synthetic plastic derived from petroleum. Its production is tied to the fossil fuel industry, which contributes to climate change.

• Microplastic Pollution: With every wash, elastane sheds tiny plastic microfibers into our water systems. These microplastics pollute our oceans and have been found in our food and water.

• Recycling Contaminant: The stretch that makes elastane so useful also makes it a problem for recycling. Even a small amount of elastane in a garment can contaminate a recycling batch, meaning that cotton shirt or wool sweater ends up in a landfill instead of getting a second life.

• Bio-based is Not Biodegradable: A common misconception is that bio-based elastane is biodegradable. In fact, these fibers are often chemically identical to conventional elastane and will also persist in landfills for centuries.

How to Shop for Sustainable Stretch

The most sustainable choice is to seek out alternatives to virgin elastane.

• Look for Recycled Content: Prioritize products made with certified recycled elastane. This fiber is made from industrial waste, which reduces the demand for new petroleum. Look for the Global Recycled Standard (GRS) label.

• Seek Bio-Based Innovations: Support brands that are incorporating new bio-based elastane alternatives. These fibers are made from renewable resources, such as corn, and are the next frontier in sustainable stretch.

• Choose Wisely: You don’t need a high percentage of stretch in every garment. For everyday basics, look for lower percentages (2-5%) or choose garments made from 100% natural fibers to ensure they are biodegradable and recyclable.

End of Life and Circularity

Elastane is not biodegradable and, due to its blending with other fibers, is a major roadblock to a circular economy. The most responsible way to manage elastane garments is to make them last as long as possible.

• Care Consciously: To extend the life of your stretchy clothes and minimize microplastic shedding, wash them only when needed, in cold water, and avoid using a high-heat tumble dryer.

• Longevity is Key: Invest in high-quality items that you will wear for years, delaying their entry into the waste stream.

By supporting recycled and bio-based innovations and being mindful of how you shop and care for your clothes, you can help ensure that comfort doesn't come at the expense of the planet's health.
