Recycled Polyester

Recycled Polyester: Its Benefits and Uses

Recycled polyester (rPET) is made by repurposing post-consumer plastic bottles and other polyester waste, reducing landfill waste and reliance on fossil fuels. It uses less energy and water than virgin polyester.

Benefits:

• Waste Reduction: Diverts plastic waste from landfills and oceans.

• Energy and Water Efficiency: Production consumes less energy and water compared to virgin polyester.

• Durable and Versatile: Maintains the strength and flexibility of traditional polyester.

• Supports Circular Economy: Encourages recycling and sustainable production practices.

Uses:

• Activewear and outdoor clothing.

• Fashion items like jackets and bags.

• Home textiles, including curtains and upholstery.

Let's take a Closer Look at Recycled Polyester

Recycled Polyester as a Sustainable Fabric

1. What is Recycled Polyester?

• Recycled polyester (rPET) is a man-made fabric produced by reprocessing post-consumer plastic waste, primarily PET (polyethylene terephthalate) plastic bottles, or post-industrial polyester waste.

• The plastic is cleaned, melted down, and spun into new polyester fibers, which can then be woven or knit into fabrics for use in clothing, accessories, upholstery, and more.

• rPET is chemically identical to virgin polyester but with a significantly smaller environmental footprint.

2. Environmental Benefits

• Reduces Plastic Waste: Diverts plastic bottles and other PET waste from landfills and oceans. For example, one rPET t-shirt can keep 5–10 plastic bottles out of the waste stream.

• Conserves Resources: Recycled polyester uses 59% less energy than virgin polyester and requires no new petroleum—a key component in virgin synthetic fiber production.

• Lowers Greenhouse Gas Emissions: Producing rPET generates up to 32% fewer CO₂ emissions than conventional polyester.

• Decreases Dependency on Fossil Fuels: As a petroleum-derived product, virgin polyester contributes to fossil fuel extraction. rPET reduces this dependency by using existing materials.

3. Durability and Longevity

• rPET shares the same performance qualities as virgin polyester:

  • Strong and durable

  • Lightweight and quick-drying

  • Resistant to stretching, shrinking, and wrinkling

• Ideal for applications where performance and longevity are critical, such as:

  • Activewear and sports apparel

  • Outdoor gear

  • Luggage and backpacks

• Its durability helps extend product lifespan, reducing the frequency of replacement and contributing to slow fashion.

4. Low-Waste Production

• The production of rPET:

  • Uses existing waste materials, reducing the need for new raw resources

  • Can be mechanical (melting and extruding) or chemical (depolymerizing and repolymerizing), depending on quality requirements

  • Generates fewer toxic emissions and consumes less water than virgin polyester production

• Recycled polyester fits within closed-loop systems, especially when combined with garment take-back programs and fabric recycling initiatives.

5. Versatility and Comfort

• rPET can be blended with natural or synthetic fibers (e.g., cotton, spandex, elastane) to achieve different textures, weights, and finishes.

• It is commonly used in:

  • Fashion apparel (jackets, dresses, t-shirts)

  • Performance and athletic wear

  • Home textiles (curtains, cushions, carpets)

  • Accessories (bags, hats, shoes)

• Modern advances have improved the hand-feel and breathability of rPET fabrics, making them more comfortable and stylish than earlier iterations.

6. Economic and Social Impact

• Growing demand for rPET has:

  • Created new industries around plastic collection and recycling

  • Provided economic opportunities in waste management, especially in developing regions

  • Encouraged brand accountability, with many companies committing to the use of 100% recycled polyester in future product lines

• It supports a circular economy model, where waste is continually repurposed rather than discarded.

7. Circular Fashion and rPET

• rPET supports circular fashion by:

  • Extending the life of plastic waste

  • Enabling repeat recyclability through advanced chemical recycling

  • Reducing landfill-bound garment waste when paired with take-back and recycling programs

• While rPET itself can be recycled multiple times, performance and recyclability may diminish over repeated cycles unless chemical processes are used.

• Closed-loop potential: If infrastructure supports it, rPET garments can be returned, shredded, and reprocessed into new textiles.

8. Things to Consider

• Microfiber Shedding: Like all synthetic fabrics, rPET sheds microplastics when washed, which can pollute waterways and harm marine life.

  • Solutions include: Using washing bags or filters, supporting brands with filtration innovations, and washing less frequently.

• Not Biodegradable: rPET is more sustainable than virgin polyester, but it's still a plastic-based material and does not biodegrade.

• Recycling Limitations: Mechanically recycled polyester may degrade over time, and not all recycling facilities can process it.

• Transparency Varies: Brands should disclose whether the rPET is made from post-consumer waste (like bottles) or pre-consumer waste (industrial scraps). Post-consumer rPET generally has a greater positive impact.
