reFashion Wardrobe


Reuse, reduce & repeat

Today we make more clothing than ever before. And the driver for this is primarily economic, rather than human need. Over the past decade, the term “circular economy” has entered the fashion industry lexicon, wherein materials are made to be reused and recycled by design.

Yet we haven’t seen the same level of recycling in fashion as we have in other spaces – such as with plastic recycling, for instance. And this is mainly because clothing-to-clothing recycling is much more difficult.

The use of recycled polyester and cotton by brands such as H&M and Cotton On are key aspects of these companies’ sustainability initiatives – but the source of these recycled fibres usually isn’t clothing. Recycled polyester tends to come from plastic bottles, and recycled cotton is usually made from manufacturing waste.

The fact is most clothing is simply not designed to be recycled. Even when it is, the fashion industry lacks the kind of infrastructure needed to really embrace a circular economy model.

Why is recycling Clothes Difficult?

Recycling clothing isn’t like recycling paper, glass or metal. Clothes are endlessly variable and unpredictable. So they’re not ideal for recycling technologies, which require a steady and consistent source material.

Even a seemingly simple garment may contain multiple materials, with fibre blends such as cotton/polyester and cotton/elastane being common. Different fibres have different capacities for recycling. Natural fibres such as wool or cotton can be recycled mechanically. In this process the fabric is shredded and re-spun into yarn, from which new fabric can be woven or knitted.

However, the fibres become shorter through the shredding process, resulting in a lower quality yarn and cloth. Recycled cotton is often mixed with virgin cotton to ensure a better quality yarn. Most fabrics are also dyed with chemicals, which can have implications for recycling. If the original fabric is a mixture of many colours, the new yarn or fabric will likely need bleaching to be dyed a new colour.

A complex garment such as a lined jacket easily contains more than five different materials, as well as trims including buttons and zippers. If the goal of recycling is to arrive at a material as close to the original as possible, all the garment’s components and fibres would first need to be separated.

This requires labour and can be expensive. It’s often easier to shred the garment and turn it into a low-quality product, such as shoddy which is used for insulation.

The Industry Challenges 

There are developed processes to recycle fibres from blended fabrics, though such recycled fibres aren’t yet widely available. Separating cellulose (present in both cotton and linen) and polyester from textile and clothing waste for new uses, including in new clothing. 

A Spanish backed project can meticulously sorts through different kinds of cotton textile waste to produce high quality, mechanically recycled, cotton fibre.

There’s also biological recycling. Fibre waste from the Rivcott cotton “gin” (or cotton engine) is composted to become fertiliser for a new cotton crop. The same is possible with natural fibres from worn-out clothing, after potentially toxic dyes and chemicals have been eliminated.

Synthetic fibres such as polyester and polyamide (nylon) can also be recycled mechanically and chemically. Chemical recycling through re-polymerisation (where the plastic fibre is melted) is an attractive option, since the quality of the original fibre can be maintained.

In theory it’s possible to use polyester clothing as the source for this. But in practice the source is usually bottles. This is because clothing is usually “contaminated” with other materials such as buttons and zippers, and separating these is too labour intensive.


Reuse before you recycle

There’s plenty of evidence that reducing the consumption of clothing by wearing items longer and buying second-hand is preferable to purchasing recycled fibre clothes.

Every item reused, is one less that is sent to landfill and one less that needs to be produced. And it has never been easier to find high quality second-hand clothing.
