The Ultimate Guide to Recycled Clothing Materials

Every year, humankind dumps a massive 2.12 billion tonnes of waste. Whether it’s regular household waste, the rubbish accumulated out and about, or even unwanted clothing as people go through their wardrobes. Thankfully, as the world becomes more aware of the environmental impact of waste, recycling is on the rise. And turning trash to treasure is a fantastic way to give everything from plastic bottles to old pillows a new life. Introducing recycled clothing materials.

So once the waste is out of our hands, what does it become? Well, these days it could be your next pair of shoes or running tights! In the fashion industry, recycled clothing materials are an emerging and welcome shift needed to address the industry’s high volume of waste, fractured processes, and linear garment lifecycles. Let’s look at the most common recycled clothing materials and break down their sustainability.

A brief history of recycled materials

We can’t introduce recycled materials without acknowledging the murky history of fabric production in the fashion industry. In the late 1940s, society saw the first signs of cheaper, virgin fabrics, and a strong presence of synthetic chemical-based materials like nylon. Enter mass production and fast supply chains, aka the infant signs of what is now known as fast fashion. Decades later, an estimated 100 billion garments are produced annually worldwide.

Technology and innovation are starting to enable a new wave of recycled clothing materials through a more sustainable and circular model.

But times are changing, and the world of fashion is at an exciting turning point. Technology and innovation are starting to enable a new wave of recycled clothing materials through a more sustainable and circular model. More brands are offering programs that give consumers a simple recycling solution for materials. And from plant- and animal-based to synthetic, various recycled fabrics are popping up which address issues such as waste, climate change, deforestation, pollution, and much more. As ever, be alert even when purchasing recycled material—it can be tricky to ensure sustainability if you don’t have all the correct information.

Not a perfect solution

We chatted to our Head of Ratings, Kristian Hardiman, aka the in-house materials expert, and he talked us through the issues with recycled clothing materials. While we are seeing positive steps in the right direction, “the reality is that the fashion industry as we know it is fraught with fractured systems. Regardless of the material and its impact, there is an underlying issue: too much virgin material is being used to make our clothing.” This overabundance has led to colossal textile waste issues from numerous areas of the production line, including pre-consumer and post-consumer waste. When it comes to our rating system, Good On You rewards brands that only use deadstock material (discarded offcuts in the manufacturing process). “In an ideal, more circular world, there would not be any deadstock material, and waste would be minimised, with more value placed on the material. A similar logic applies to recycled synthetics. It is mainly due to our broken and overwhelmingly linear system that recycled materials are a solution at this point in time.”

Regardless of the material and its impact, there is an underlying issue: too much virgin material is being used to make our clothing.

Kristian Hardiman – Head of Ratings

A mixture of lower-impact materials is needed going forward, and the industry can’t be reliant on a single material to repair the system. Organic fabrics require land and can only be grown in some regions of the world. Recycled synthetics don’t have the land-use demands but are much higher in energy intensity. “At this stage, there is no one right way to go about it. It is diverse and dynamic. So while sustainability and ethical practices continue to make their mark on the fashion industry, we need to find solutions to support the shift to a more circular fashion industry, acknowledging that sometimes the solution is driven by the problem.”

Recycled cotton

Did you know that conventional cotton is extremely intensive to produce? The fluffy white plant requires vast amounts of water, a lot of space to grow, various harmful chemicals, and overall, is very labour intensive. Despite this, cotton is one of the easiest fabrics to make into a recycled garment. It’s worth checking whether a recycled cotton garment is derived from organic or conventional cotton and if it’s made from pre-consumer or post-consumer waste. Thankfully, cotton is entirely biodegradable—able to break down over time. So, if done correctly, it fits within a circular model, setting it apart from many other synthetic recycled materials.

Our verdict:

Go for recycled cotton as a first option, particularly if you can identify its origin as organic cotton. Extend the life of your cotton garments by using gentle, plant-based washing powders and cold water cycles.

Recycled wool

Wool is a durable animal-based fibre that is known for its longevity, warmth, and comfort. In its original form, wool is a resource-intensive material to produce and has associated ethical concerns. Recycled wool, like that traditionally processed in Italy by Manteco, reduces the environmental and ethical impacts significantly and, with so much of the fibre already in circulation, is becoming a desired recyclable option. It’s also diverse and easy to mix with other materials such as fleece. The industry is beginning to see less demand for virgin wool with the higher value placed on discarded garments or offcuts in the manufacturing process.

Our verdict:

Support brands using recycled wool over virgin wool. To extend the life of a woollen garment, wash less often and by hand.

Recycled down

Down—usually goose and duck feathers—is the soft inside padding commonly used in furniture such as cushions and doona covers, and insulated clothing like ski jackets and coats. Recycled down is derived from the simple process of diverting household items from landfills, instead using the feathers for a new garment. This is an ideal sustainable option, as the recycled insulation does the same thing as the virgin down and feathers. The recycled option is also more ethical—even better if the brand can disclose the processes and origins of the down and feathers.

Our verdict:

Choose recycled down over virgin down every time to avoid animal cruelty. Look for brands who disclose where they source the down from in its original form to ensure it was sustainably sourced and certified.

Recycled cashmere

Recycled cashmere is a welcome addition to the industry as the original form significantly impacts people, animals, and the planet. Cashmere is an ancient fabric that dates back to the 13th century. Originally a commodity made on a smaller scale from a specific breed of goat, the virgin material now has a much larger environmental footprint. The less intensive recycled cashmere option has fewer years under its belt but is already favoured as an eco-alternative by brands that traditionally used virgin cashmere. The soft, lightweight material is much more sustainable in its recycled form, placing a higher value on the material itself by upcycling the pre-consumer offcuts and leftover fabric waste.

Our verdict:

Only source recycled cashmere if you really need it, and avoid virgin cashmere all together. Take the same ethical and environmental factors into consideration for recycled materials as well.

An up and coming alternative to nylon, ECONYL is a recycled plastic material created by Italian firm Aquafil. The company uses synthetic waste such as industrial plastic, waste fabric, and fishing nets from oceans. They blend and transform this waste into a recycled nylon yarn that has the same appearance and quality as virgin nylon—a perfect replacement! ECONYL appears in stretch garments like swimwear and activewear. Remember synthetic recycled materials still create residual microplastics, though it’s important to note that Aquafil is in the process of creating a form of ECONYL that doesn’t shed. In the meantime, you can use washing machine filters or washing garment bags for these items to minimise the microplastics released in the wash.

Our verdict:

Avoid traditional nylon by looking for brands that use Econyl, but simultaneously choose recycled plant based fibres where possible and be diligent about microplastic protection in your laundry!

Recycled PET plastic

You might be thinking—I know water bottles can be recycled into other plastic water bottles, but how can they be made into clothing? Recycled PET (polyethylene terephthalate) has been in development since the early 90s, and thanks to the evolution of technology and the search for more solutions to plastic pollution, buying recycled PET plastic garments is a good option when trying to avoid the production of new plastics.

Like all fabrics, recycled PET has its shortfalls. There is not yet a reliable recycling solution for recycled PET plastic items, meaning they break the closed-loop system, so brands should ensure they can account for a garment’s longevity. Some brands manage this by offering repair services to extend a garment’s lifecycle, which is a good first step.

Be especially careful with garments such as fleeces and other recycled PET wearables, as studies have shown that plastic microfibres are polluting waterways and that fleece made from recycled PET plastic may be even more polluting than its original form. Buying garments that don’t need to be washed as often, such as rain jackets or sneakers, is a good way to avoid contributing to microfibre pollution with your clothes.

Keep an eye out for brands taking on more sustainable recycled synthetic materials such as Netplus or Repreve, and do your research before diving straight into a recycled plastic product.

Our verdict: 

Recycled PET plastic is definitely better than virgin polyester, but still choose recycled PET plastic garments selectively, prioritising longevity over a quick spend. When purchasing a recycled PET plastic garment, check if the brand offers a repair program for after use. Also, wash in a garment bag or guppy bag to mitigate the inevitable microplastics release!

Recycled rubber

While old tires may not sound like an appealing addition to your wardrobe, they should! Today, approximately 1 billion tires are produced annually, and figuring out what to do with them once they’re no longer fit for the roads is tricky. Due to the chemicals often involved in rubber production—which can be made from natural or synthetic components—burning or tossing it isn’t exactly sustainable or good for the planet. Luckily, tires and other rubber products are relatively easy to upcycle and recycle into things like bouncy flooring and plant pots. And, yes, even fashion. You can find everything from jewellery to bags to shoes using recycled rubber.

Our verdict:

Recycled rubber is a good sustainable option for fashion and beyond. Try out recycled rubber as a quirky and innovative option that saves harmful material from ending up in a landfill. Once the product has reached the end of its life, check with your local waste processing facilities to see if they will accept it for further recycling.

Recycled leather

The leather industry is fraught with issues, from poor animal welfare standards to mass deforestation to water pollution. But leather is a long-lasting and technically biodegradable material, and with so much of it circulating through fashion, creating recycled leather goods is one way to extend the life of a product that had such a high upfront cost on animals, people, and the planet.

Our verdict:

There are many lower-impact leather alternatives out there, but if you must have it, recycled leather is a good option that means you aren’t directly contributing to the suffering associated with new leather.
