RECYCLED POLYESTER
WHAT ARE THE ADVANTAGES OF RECYCLED POLYESTER?
There are lots of advantages of recycled polyester that you should know about.
Afterall, there is a reason why standard polyester has been used for decades. A recycled version should have all of the pros with less of the negatives - right?
Also known as rPET, has been ranked B grade in the Made-By sustainable fabric ranking. That places it alongside Tencel and Organic Cotton, so it is definitely considered a sustainable fabric.
Is made by melting down plastic and spinning it into a new polyester fibre. Generally, it takes 5 water bottles to make enough fibre for one T-shirt.
In comparison, regular polyester is made from crude oil. To turn crude oil into plastic fibres requires a process called polymerization. These fibres can then be woven into a yarn to make fabric. As you’d expect, this requires a lot of energy, water and chemicals.
1. Reduced landfill waste
Recycled polyester is made from old plastic bottles, diverting waste from landfill and reducing demand for virgin materials. The UN estimates that we produce around 400 million tonnes of plastic waste every year. Whatever we prevent ending up in landfills is a good thing.
2. No virgin materials
As a recycled fabric, rPET doesn’t rely on virgin materials. This means a lot less crude oil and gas, which is what regular polyester is made from. If we were to switch all polyester to recycled polyester, there would be a lot less demand for this non-renewable resource.
3. Energy efficient production
Recycled polyester uses less energy compared to making clothes from virgin polyester. How much less energy? The Swiss Federal Office for the Environment says recycled polyester textile uses a massive 59% less energy to create compared to regular polyester fabric.
4. Lower CO2 emissions
It takes much more power to produce virgin polyester from crude oil and gas. There is also no need for additional oil to create the material. WRAP estimates that the production of recycled polyester reduces CO2 emissions by 20.7% compared to regular polyester. This means a lower carbon footprint.
5. Lower water footprint
In comparison to regular polyester, the production of rPET consumes less water. However regular polyester is generally seen having a lower water footprint than comparable materials like cotton.
6. Less water pollution
It is impossible to trace many regular polyester fabrics to their source. The reality is that much of the fabric will be produced with little regard for the environment. This means water pollution during production, treating and dying the fabric. Recycled polyester usually has more transparent supply chains, and production facilities prevent local water pollution.
7. Recycled polyester is ethical
Recycled polyester is usually more ethical than regular polyester. This is because the supply chains which recycle the fabric are more transparent, especially when compared to conventional fabrics where it can be incredibly difficult to trace the origins of a garment.
8. Recycled polyester is durable
One of the reasons polyester has been so popular for decades is because it is durable. Similarly, recycled polyester fabric is strong and durable, ideal for clothes, bags, and performance gear.
9. Easy to care for
Polyester is considered easy to care for. Recycled polyester can be machine washed at a lower temperature, requiring less energy through its consumer lifecycle.
10. Quick-drying
Recycled polyester is quick drying, just like regular polyester. This is why it’s perfect for outdoor and athletic wear.
11. Breathability
Recycled polyester is engineered to be breathable, allowing air to flow through the threads of the fibre quickly and easily. This prevents buildup of moisture and heat, and allows for moisture wicking.
12. Moisture wicking
Polyester is well known for its moisture wicking properties, making it an excellent choice for athletic wear and active clothing. There’s a reason it’s used in sports clothes so much.
13. Recycled polyester is versatile
Think of how many different products are made from polyester - bags, clothing, shoes, upholstery, and more. Recycled polyester fabric turns waste plastic bottles into a range of products we wear and use.
14. Recycled polyester is affordable
Recycled polyester fabric is often more affordable compared to many sustainable materials. Ultimately this makes it more accessible to a wider range of customers, which will help bring about a sustainable fashion revolution.
15. Softness
Chances are you have regular polyester in your wardrobe. It might be a polyester fleece, pyjamas, leggings, a sports top or dressing gown. Each of these items is soft. Recycled polyester fabric can be engineered to have a soft and comfortable feel.
16. UV protection
A benefit you might not have considered about recycled polyester is UV protection. Polyester fabrics usually provide sufficient UV protection (UPF 30+), while other fabrics such as cotton, linen, and viscose frequently offer poor UV protection.
17. UV resistance
Different from UV protection, polyester fabric has a good resistance to UV rays. This means the material won’t break down or lose its colour when exposed to the sun for long periods of time.
18. Colourfast
Colours don’t fade in recycled polyester fabrics. This is because the material can easily be dyed into a wide range of colours, and these colours won’t run. This is especially true when compared to fabrics like regular cotton, which takes a lot of processing to bleach and eventually dye into the colours we have grown to expect.
19. Hypoallergenic
Recycled polyester fabric is hypoallergenic. This means it is a good choice if you have sensitive skin or react to certain fibres.
20. Promotes a circular economy
Recycled polyester helps promote a circular economy. It raises awareness of the need for change in the fashion industry. If more of us come to expect fast fashion retailers to use sustainable fabrics like recycled polyester, they will have to change. This is how you and I can do our bit to promote a more sustainable future.
