    Sustainable fashion is all the rage right now, but what does that truly mean? Sustainable textiles are those that can be easily recycled and are made using renewable resources. Recycled polyester from worn clothing may be used to create new textiles. How long would something made from recycled polyester last? The benefits of recycling fibres & their impact on the planet are the subject of this essay.

    Is it true that you have no idea that rayon is a synthetic fibre made from recycled plastic? There is some doubt as to whether or not recycled products are suitable for the ecosystem, and the recycling process can be rather untidy. Read on to find out what we know about the dangers this chemical may have to your health. Because it is made from recycled plastic bottles, involves the provision is a fantastic option for those who wish to reduce their environmental footprint. Yet, how much less harmful to the environment is recycled polyester? The answer is dependent on the particulars of the recycling procedure for the cloth.

    In this case, we have three unique types: mechanical, chemical, & biological. To create polymers, plastics are chemically or bacterially broken down into smaller molecules that are then reused. Among the many fabrics in common use today is material. To make recycled polyester, bottles from around the world are collected and repurposed.

    Recycled biopolymers may appear to be a sustainable option because consumers are reusing plastics that would otherwise end up in the oceans or oceans; however, there are aspects of their products that make them less sustainable, the more notably the pollution formed by every one of these production lines during procedure, which creates significant health risks.

    However commonplace it may be, recycled polyester still suffers from widespread misunderstanding. Some people believe falsely that involves the provision isn't as durable as virgin cotton or as robust as natural fibres. Recycled polyester can match or even exceed the quality and durability of virgin polyester. Of course, this depends on the precise recycling process employed to make the fabric.

    Consider the following points before making a purchase: To what extent does it make use of reclaimed materials? How much colour is leaking through? How much scrap gets thrown away during manufacturing? Think over the specifics listed here to decide if eco-friendly apparel is right for you. Can this solution, which prevents waste from entering landfills or waterways, be sustained indefinitely? Unfortunately, no easy answers exist.

    It takes a lot of energy to recycle plastic into resins molecules, which then are mixed with natural gas or petroleum to create new yarns for spinning, thus the final product of recycled polyester isn't exactly energy efficient.

    Manufacturing with recycled materials uses a fraction of the amount of water and oil required for production from virgin materials. The plastic bottles that are used to create recycled polyester are otherwise destined for the trash. However, recycling polyester requires a lot of time, money, and resources due to the amount of energy and chemicals required.

    Whether or not these chemicals & energy can be used safely in the future depends on the percentage of recycled polyester on your clothing. Need more information before making a decision? For this reason, we highly recommend that you read this entry on our blog.

    FAQs About Polyester

    Polyester is a synthetic manufactured fibre that was first constructed in a lab in the 1930s by chemical corporation DuPont. The most common form of polyester is polyethylene terephthalate (PET), which is used in everything from clothing to packaging.

    Since the 1960s, polyester has become the world's most popular fabric, partly for its functional properties. Due to the molecular structure of PET, it means that polyester clothing is often resistant to stretching and shrinking, is easy to clean, quick to dry and less prone to creasing. The popularity of polyester isn't waning – according to Textile Exchange, it is the most widely used fibre globally, with a share of 52% of global fibre production in 2018.

    OK, so it's not pure magic. Recycled polyester is made by breaking down used plastic into small, thin chips, which are processed and eventually turned into yarn. Processes vary by specific fabrication, so let’s focus on the recycled polyester used in the Ridgeline Bag collection, Repreve

    Manufacturing this ultra-durable fibre begins with truckloads of plastic bottles - but just the clear ones, which provide a neutral base for applying dyes. Next, the bottles are stripped of their labels and shredded up into tiny pieces that look like plastic confetti. 

    The festive vibe is appropriate: Recycling single-use plastics dramatically decreases greenhouse gas emissions compared to producing virgin polyester. Water usage is also significantly decreased during production. These plastic pieces are then converted into tiny pellets, melted, and spun into yarn.

    Unlike natural fibres such as cotton, conventional polyester does not require land for cultivation. That is why it has become so ubiquitous in clothing as it requires less attention to nurture.

    Despite this, polyester has an overwhelmingly harmful impact on the environment and ecosystems involved in production. As a synthetic fibre, it is made from petroleum-derived chemicals and is associated with the risks of fossil fuel extraction, chemical spillage and biodiversity loss.

    Creating polyester is energy and water-intensive process which is exacerbating the fashion industry's impact on the planet. As the industry is predicted to use 26% of the world's carbon budget by 2050, it must learn to move away from resource-heavy materials like polyester.

    Polyester is also damaging to the environment because it is fuelling the plastic pandemic. Washing polyester means that plastic microfibres are released into water streams that run into our rivers and oceans. 

    For example, according to Lucy Siegle’s Turning The Tide On Plastic, washing 6kg of clothes can result in anything between 137,951 fibres (for polyester-cotton clothes) to 728,789 fibres (for acrylic clothes) released as oceanic pollution.

    Nearly half of the world's clothing is made of polyester, and Greenpeace forecasts this amount to nearly double by 2030. Why? The athleisure trend is one of the main reasons behind it: an increasing number of consumers are looking for stretchier, more resistant garments. 

    The problem is, polyester is not a sustainable textile option, as it is made from polyethylene terephthalate (PET), the most common type of plastic in the world. In short, most of our clothes come from crude oil. Yet, at the same time, the Intergovernmental Panel on Climate Change (IPCC) calls for drastic actions to keep the world's temperature to a maximum of 1.5 °C above pre-industrial levels.

    One year ago, the non-profit organisation Textile Exchange challenged over 50 textile, apparel and retail companies (including giants like Adidas, H&M, Gap and Ikea) to increase their use of recycled polyester by 25 per cent by 2020. 

    It worked: last month, the organisation issued a statement celebrating that signatories have not only met the goal two years before the deadline, but they have also actually exceeded it by upping their use of recycled polyester by 36 per cent. In addition, twelve more companies have pledged to join the challenge this year. As a result, the organisation forecasts 20 per cent of all polyester to be recycled by 2030. Recycled polyester, also known as rPET, is obtained by melting down existing plastic and re-spinning it into new polyester fibre. 

    While much attention is given to rPET made from plastic bottles and containers thrown away by consumers, in reality, polyethylene terephthalate can be recycled from post-industrial and post-consumer input materials. But, to give an example, five soda bottles yield enough fibre for one extra-large T-shirt.

    Although recycling plastic sounds like a good idea, rPET's celebration is far from unanimous in the sustainable fashion community. However, FashionUnited has gathered the main arguments from both sides.

    Like traditional polyester, recycled polyester is an artificial fabric produced from synthetic fibres. However, instead of utilising new materials to craft the fabric (i.e. petroleum), recycled polyester uses existing plastic. In many cases, those existing plastics are your old water bottles, which are then processed and magically transformed into that awesome, rip-resistant Bluff Utility Backpack sitting next to your desk.

    Recycled polyester (rPET) uses PET as a raw material which is often found in water bottles. To turn these bottles into the material, the plastic is sterilised and crushed. 

    It is then spun into a string of yarn which can be transformed into a fibre and then blended into a fabric. Clothes commonly made from recycled polyester include sportswear, loungewear and outdoor garments like puffer jackets.  

    Why Choose Recycled Polyester?

    This eco-friendly alternative to conventional textiles retains all the qualities that have rendered fibre a hit since its inception in the 1940s. Water bottles are not recyclable, hence this material is frequently employed in the creation of high-performance, long-lasting items to reduce waste and environmental impact.

    What Are The Benefits Of Using Recycled Polyester?

    Numerous advantages exist when recycled polyester is used in clothing design. First, as rayon accounts for more over half of the fibres used in the textile and garment industry, replacing with a recycled substitute would immediately be better for lowering reliance on fossil fuels. The widespread adoption of a non-virgin substitute will have a beneficial effect on future energy requirements. In addition, this will give businesses a tool they may employ to lessen the glasshouse gas emissions caused by their supply chain.

    The second benefit of recycled polyester is that it helps cut down on the yearly disposal of clothes, which accounts for over 48 metric tons and is a significant part of seismic trash. Seeing that rubbish may be put to good use is a natural method of encouraging recycling. Likewise, it demonstrates to consumers the futuristic potential of eco-friendly materials.

    Recycled polyester also has a smaller carbon footprint than virgin polyester, which is a nice bonus. Carbon dioxide emissions are reduced by 79% as compared to those caused by making virgin PET, according to a study conducted in 2017. As a result, firms that use recycled polyester may be able to make greater contributions to the Paris Agreement as well as the Sustainable Development Objectives of 2015.

    The estimate of 8 million tons of waste ends up in the earth's crust each year; transforming garbage into cloth helps reduce this number. This can also help mitigate the devastating impacts of plastic pollution on ocean life and the marine species that calls them home.

    Finally, the fashion sector can benefit from more collaboration and creativity by switching to other recycled fibres beyond recycled polyester. As an illustration, in 2019, the Textile Exchange issued a challenge to more than 50 brands like Adidas, Gap, and H&M to boost their the use recycled polyester in 25% by 2020.

    They not only completed the project on schedule, but their utilisation grew by 36% as well! In order to reduce emissions and wean ourselves off of fossil fuels, more and more companies are making pledges to recycle 20 percent of the world's cotton by 2030.

    What Are The Recycled Polyester Limitations?

    However, using recycled polyester does not represent a quick fix for the fashion industry's negative effects on the environment. rPET is not an option because of the damage it does to the environment. Still, the material's own microplastic emissions pose a threat to the abovementioned plastic pollution.

    The primary issue with recycled polyester garments is that their recyclable condition is not guaranteed. This is because many companies don't have the tools and space to properly deconstruct the fibre parts before they may be reused.

    Furthermore, rPET clothing can't be recycled permanently because repetitive heating destroys the plastic and may eventually cause its material's durability attributes to fail. Since recycled polyester is chemically identical to virgin polyester, it can be thrown away in the same manner.

    The use of recycled polyester also carries the risk of skin irritation because many PET water bottles include chemicals that can be damaging to the skin. For instance, the plasticiser 'antimony' has been linked to cancer and can leak into PET bottles. Although the concentration of antimony in rPET clothing is typically not high enough to cause harm to humans, Textile Exchange emphasises the importance of developing alternatives to these compounds.

    How To Make Sustainable Fashion Decisions

    The following seem to be some sustainable shopping ideas to consider when purchasing recycled polyester or recovered fibres in general:

    • Just because a company employs the practise of content reuse does not make that company's approach to content marketing "circular."
    • Brands cannot be deemed responsible if they incorporate recycled items in their collection but do not pay their supply chain workers a living wage.
    • Natural fibres, like as hemp, are the most eco-friendly choice for clothes, but totally circular options should also be examined.
    • Check the garment's credentials to ensure it complies with all of your ethical requirements for doing business.
    • Independent organisations that evaluate the proof that clothes brands present can be trusted in regards to their sustainability promises.

    The Benefits Of Recycled Polyester

    Keeping Plastics Out Of Landfills And The Ocean

    The nonbiodegradable polyester used to make recycled polyester is saved from the landfill or perhaps the ocean and given a new lease on life. The Ocean Conservancy, a non-governmental organisation, estimates that each year, 8 million tonnes of plastics are discharged into the ocean, adding to the projected 150 million tonnes currently floating around and in marine areas.

    By 2050, there will be more rubbish than fish in the water if we keep going at this rate. All sea turtle species and over 60% of all seagulls have plastic in its stomachs because they have mistaken it for food.

    how sustainable is recycled polyester (1)

    The Environmental Protection Agency (EPA) estimated that in the United States alone, 26 million tons of plastic ended up in landfills in 2015. The European Union anticipates that approximately will be produced annually by all member states.

    The clothes that people wear are undeniably a contributing factor. According to a survey by the Waste and Resource Action Programme (WRAP), annually, the United Kingdom throws away almost 140 million pounds' worth of clothing.

    Textile Interchange Board Member Karl Magruder sent an email to FashionUnited stressing the importance of repurposing plastic in innovative products for the benefit of both people and the environment.

    Rpet Is Equally As Good As Virgin Polyester But Requires Fewer Resources To Manufacture.

    There is little quality difference between recycled and virgin polyester. However, a 2017 study even by Swiss Federal Office again for Environment found that its production used 59% less energy as virgin polyester. CO2 emissions are reduced by 32% during production of rPET, according to WRAP's calculations. Life cycle studies show that rPET is superior to virgin PET, Magruder says.

    Further, polyester made from recycled materials can lessen the need for fossil fuels used in the plastics manufacturing process.  Polyester that has been recycled

    cuts down on how much we need to rely on crude oil, "Patagonia, a company known for its eco-friendly advertising campaigns, produces its signature fleece from plastic soda bottles, discarded industrial waste, and donated apparel, so states the company's official website. It reduces garbage, which slows down landfill decomposition and reduces emissions of hazardous gases from incinerators. The label also helps spread the word about alternative ways of recycling old polyester clothes.

    "American clothing brand Nau is also known for favouring self sustaining fabric options, and the company claims that because polyester accounts for approximately 60% of global PET manufacturing, roughly twice that used in plastic water bottles, creating a non-virgin supplier base for polyester cellulose fibres has the potential to influence worldwide energy and resources requirements massively.

    The Drawbacks Of Recycled Polyester

    Recycling Is Not Without Limits

    A lot of clothing isn't made entirely of polyester, but rather a blend of polyester and other materials. The difficulty of recycling them increases accordingly. For instance, combining polyester with cotton is technically possible. However, the trials are still in progress.

    Finding procedures that scale well is difficult, and we haven't gotten there yet "admitted Magruder in an interview with Suston Magazine in 2016

    Many textiles cannot be recycled because they have been laminated or finished in a way that prevents recycling.

    Polyester garments can only be recycled so many times. Mechanical or chemical recycling processes are available for PET." The Recycler Machine

    is to recycle a mason jar by washing it, shredding it, and turning it into a polyamide microcontroller, which would then go through the standard fiber-making procedure.

    To be considered "upcycled," a hdpe plastic item must be converted back to its nucleotides, which were originally extracted from virgin polyester.

    Since its inception, material recovery has been the primary source of rPET because it offers the highest return on investment compared to the other two processes and requires no chemicals beyond those used to clean the input materials. The Swiss Federal Office again for Environment notes that "the fibre may forfeit its strength during this process," thus there is some risk involved.

    According to the website Textile Exchange, polyester clothing cycles have the potential to become "a capitalist nation" in the future because of the ease with which they may be recycled without compromising the quality of the final product.

    In a nutshell, some people who share Grossman's perspective believe that the world will have to use less plastic. Assuming that anything they throw away can be recycled could lead some to justify the use of single-use plastics.

    Too bad we can't recycle every piece of foam we buy. In 2015, only 9% of any and all plastic were consistently recycled in the United States.

    Others contend that natural fibres must be given a fair shot in the fashion business, and that rPET should be seen with more complexity. According to a 2010 analysis by the Stockholm Environment Institute, although 59% less energy is required to make rPET than virgin polyester, this is still more than is required to generate hemp, wool, cotton, or ordinary cotton.

    Microplastics Are Released By Recycled Polyester.

    One more point: not everyone agrees that rPET helps keep waste out of the ocean. That's why it's still producing synthetic textiles. The assertion that rPET decreases the amount of rubbish that ends up in the ocean is, finally, contested. According to research conducted by Plymouth University in the United Kingdom, over 700,000 plastic fibres are released into the environment during just one washing machine cycle.

    As of 2011, it was determined in a report published in the journal Environmental Science Technology that microfibers made up 85% of all rubbish observed on beaches throughout the world. Fabrics made from virgin and recycled polyester both add to the pollution caused by microplastics.


    Textiles that are sustainable have a low environmental impact since they are both recyclable and produced with minimal dependence on nonrenewable resources. Used polyester clothes can be recycled into new fabrics, however the environmental benefits of this practise are unclear. Although rayon is a synthetic fibre that can be created from plastic bottles, its environmental suitability is debatable, and the recycling process is often messy. The solution is conditional on the method used to recycle the fabric. Although recycled biopolymers seem like a green choice at first glance, certain of their properties actually make the final goods less eco-friendly.

    It takes a lot of energy to recycle plastic into resins molecules, which are then blended with natural gas or petroleum to make fresh yarns for spinning, yet recycled polyester can match or even surpass the quality and durability of virgin polyester. Recycling polyester takes a lot of time, money, and resources due to the energy and chemicals necessary, but it uses a fraction of the water and oil required for manufacturing from virgin ingredients. When making a purchase, think about whether or not recycled polyester can be used safely in the future, how much colour is leaking through, how much scrap gets thrown away during manufacturing, and other factors to determine if eco-friendly clothing is good for you.
