Circularity and wool as a circular fibre

Wool, by nature a circular fibre, can help brands enter more easily into the development of circular products.

Circular design in the textile industry uses regenerative materials, keeps garments in use and provides pathways for reuse, recycling and biodegradation at end-of-life. Discover how wool can be used within a circular textile economy.

acting as a launchpad to help achieve circular design practices.

Align to the circular economy with wool

Renew

Use renewable resources

step-1.jpg

Every year, sheep produce a new fleece, making wool a completely renewable fibre source. Wool is grown by the simple mix of sunshine, water, grass and fresh air. That is, wool grows on a sheep’s body because of the proteins, lipids and minerals naturally absorbed  through their diet, in much the same was as human’s grow hair.

Environmental factors including climate, day length, soil type and feed type all contribute and influence the production of sheep’s wool. There is a use for every part of the wool fleece, nothing is wasted.

If a sheep’s fleece is not shorn seasonally it can build up and potentially negatively affect the sheep’s health.

 

Reuse

Keep materials and products in use for a long time

step-2.jpg

The number of times a garment is worn significantly influences the overall environmental impact of that garment. To reduce the environmental impact of garments, designers need to create garments that are designed for long life. For designers and brands to do this, here are 5 design steps to consider:

  1. Choose quality fibres that are durable
  2. Design garments that meet the needs of the wearer
  3. Use quality dyes, finishes and construction methods
  4. Design garments that don’t go out of fashion
  5. Design garments that can evolve with the needs of the wearer, especially adjustable fit

Wool is a quality fibre and is typically kept longer than other garments with an active service first life estimated to be 20-30 years. Wool is highly valued in the resale and recycling markets and can be recycled in the closed-loop and open-loop recycling systems.

Wools performance attributes, such as odour, stain and wrinkle resistance also ensure that wool garments can be laundered less often and retain their ‘as-new’ appearance for longer.

Remove & Reduce

Remove pollution & reduce waste

step-3.jpg

Globally, an estimated 92 million tonnes of textiles waste is created each year and the equivalent to a rubbish truck full of clothes ends up on landfill sites every second.[1]

Wool is made of a 100% natural biodegradable protein, similar to that found in human hair. When a wool product reaches its end-of-life and is disposed of, the wool fibre readily decomposes in soil, slowly releasing valuable nutrients and carbon back into the earth, acting like a fertiliser. Wool is also completely biodegradable in marine environments.[2] This means that wool does not contribute to microplastic pollution.

Regenerate

Regenerate natural systems

step-4.jpg

Ecosystems evolve with diversity in plant and animal species. These species interact and provide stability within an ecosystem. Animals are of course, part of this biodiversity and for grassland systems to function naturally, grazing animals play a key role. This is where wool growing can play a role in regenerating grassland ecosystems.

Sheep are grazing animals that fit into a regenerative agriculture system to build soil organic matter, sequester carbon and support biodiversity. Sheep act as natural fertilizers and return essential nutrients to the soil. Learn more about regenerative agriculture here.

Sheep live on grasslands which are regions that are not used for growing food, and many Australian woolgrowers encourage biodiversity through riparian protection and revegetation.

Repair & Recycle

Repair & recycle

step-5.jpg

Wool’s attributes are so highly valued that, even after a garment has finished its long service life with one person, the fibre is still suitable to be kept in use in the via three further ways:

  • 1st life extension – Reuse: Wool is the most reused fibre on the planet of the major apparel fibres, with wool garments often preferentially donated or sold for extended life. According to a Nielsen wardrobe study, 50% of wool and wool blend garments are donated to charity, family, friends or sold.
  • 2nd life extension – ‘Closed loop’ recycling: This involves high-value wool garments deconstructed to enable new yarns to be spun and new high-value garments fabricated. Wool is the most recyclable fibre on the planet of the major apparel fibres.
  • 3rd life extension – ‘Open loop’ recycling: This is essentially ‘down cycling’, in which wool products are pulled apart and fabricated into cheaper non-woven products for insulation, padding, interiors etc.
Reconnect

Celebrate diversity

step-6.jpg

The wool supply chain is long, complex and diverse. The industry supports the livelihoods of approximately 200,000 people in Australia. These farmers are mostly generational small farmers whose main income is their wool clip.

Throughout the supply chain, wool supports the livelihoods of many individuals and communities throughout Asia and Europe and supports the continuation of cultural expertise and traditional knowledge in weaving, knitting, dyeing and garment making.

Knitted on circular machines machines, NAGNATA’s seamless garments not only reduce fabric wastage but also environmental impact - a key pillar of the circular economy.

<p>Extending the use phase</p>

Extending the use phase

Wool garments need less laundering, reducing energy and water consumption as well as maintaining the garment’s ‘as-new’ appearance. A wool sweater can be worn 14 times before washing. Increasing its number of wears to 400 across its entire lifespan can reduce the environmental impact of that garment by up to 68%.

Three steps to design for circularity with wool

Design of long life

step-1.jpg

Studies show consumers hold the power to dramatically reduce the environmental impact of their clothing. For consumers to re-wear clothing and keep it in use for a long time, garments need to be designed for long life. Here are 5 design steps to consider:

  1. Choose quality fibres, yarns and fabrics that are durable.
  2. Design garments that meet the needs of the wearer.
  3. Use quality dyes, finishes and construction methods.
  4. Design garments that don’t go out of fashion.
  5. Design garments that can evolve with the needs of the wearer, especially adjustable fit.
Educate consumers on best-practice care

step-1.jpg

The use-phase of a garment’s lifecycle is the greatest factor in determining the environmental footprint of a garment. Here are 4 initiatives designers and brands can implement to reduce the environmental impact of clothing.

  1. Promote re-wearing of wool garments. Increasing the number of wears per wool garment lifespan can reduce that garment’s environmental impact by up to 68%.
  2. Communicate the care instructions for wool garments such as washing wool at 30°C (86°F) or less, air-dry wool garments and reducing the frequency of laundering - the optimal number of wears per wash for a wool sweater is 14 times.
  3. Offer consumers take-back options to give wool garments a second or third life.
  4. Offer repair services to extend the life of a garment.
Design for after-life

step-1.jpg

By 2030, we are expected as a whole to be discarding more than 134 million tonnes of textiles a year. To align to the circular economy, clothes must be designed for after-life. This doesn’t just mean recycling, this includes the second and third life of a garment. Here are five steps for you to consider:

  1. Choose natural fibres - they are inherently biodegradable.
  2. Communicate the benefits of natural fibres. Adopting best-practice care will ensure garments maintain their ‘as-new’ appearance and can re-enter the resale and reuse market.
  3. Design for disassembly - this will ensure each component of a garment can be reused and recycled.
  4. Explore wool recycling options - with a scaled, commercial recycling industry there are multiple options to create value through wool recycling.

Explore take-back and donation opportunities - wool has high reuse and resale value which you can utilise to keep garments in use for a second and even third life.
