Design for recycling is an important factor with respect to circularity. We'll assume you're ok with this, but you can opt-out if you wish. Generally, the lack of scaled-up technologies for recycling textiles means that the amount of recycled PET available is much less than the amount of PET that is currently produced from petroleum. Besides this, it might also provide an economic incentive to collect and recycle PET bottles, which is good for the environment. Unifi has turned 4 billion used plastic bottles into yarn in the last seven years. Only 9% of the Earth’s plastic has been recycled, but we’re committed to boosting that percentage by using more recycled polyester every year. Sold under the name Repreve, the yarn is fashioned into Polartec fleece jackets, automotive upholstery fabric, men’s slacks, sweat-wicking socks etc. But why specifically are PET bottles being used? Our items advertising and marketing network at all more than the China regions. The recycled yarn is ready to be used and woven or knitted into fabric again, and has the same aesthetics and functional performance as conventional polyester yarn. Sorting and grading plastic bottles are chops and grinds into small bits that melt and soften plastics passes through a number of tiny holes which results in thin filaments. And due to legislations changes in places like Europe and a greater focus on recycled content in plastic packaging, the competition for recycled PET is likely to further increase. This is because PET drinks bottles represent a pure, high-quality form of PET. We also use third-party cookies that help us analyze and understand how you use this website.

In scientific terms, this is described as them having a high ‘molecular weight’. Then these pellets are again melted, pushed through shower head like tiny holes and operated upon by air and temperature. Your email address will not be published. However, it is important to think about wider and more long-term implications of using only PET bottles as a feedstock for recycled polyester clothes. These cookies will be stored in your browser only with your consent. Integrating circularity at the design stage demonstrates an approach that takes the whole life cycle of a textile into account, including the end-of-life of the product. The answer is simple: polyester fabric is made from Polyethylene terephthalate, or PET. To the average, eco-conscious consumer this seems like a very attractive proposal: buy new clothes made from recycled old clothes. One can think about it this way: if all kinds of different colours get thrown together, without stripping the dyes the output will likely be a nondescript, brown-ish fibre. But the short answer is: because we can’t do this (yet). Other initiatives could also help. First of course, is the material itself; the yarn provides a use for plastic substances that would have otherwise been thrown into a landfill. Without the ability to recycle polyester textiles, this situation will always remain, and usage of petroleum to make PET for all products will remain high. So why is the word polyester so ambivalent? In their ‘natural environment’, the drinks industry, they could be recycled many more times within a closed-loop circular economy. SEE THE WINNERS. It’s always possible that fraud could creep into the system somewhere along the line. Hence taking PET bottles from relatively closed loops and using them for textiles trap the material in a one-way street, for now. While recycled polyester made from PET bottles has a lower environmental impact, the wider implications and long-term prospects need to be taken into account. Thanks to new recycling technologies, we can now turn plastic bottles into soft, polyester thread to make eco-friendly clothing. At the same time, there's an opportunity to recycle other plastic like food storage containers and plastic cutlery. 48 PET bottles with a capacity of 1.5 L are used to produce one kilogram of DIOLEN®ReCIRCLE yarn.

These chips or flakes are then sent to the yarn spinning mills, where they’re melted down and turned into yarn to create new fabric. This is because they are simply not scaled-up far enough yet. Furthermore, taking PET bottles away from the drinks industry triggers a competition for this feedstock between the fashion and drinks industry. Instead, most recycled polyester is actually made from single-use plastic bottles. As it is challenging to deal with billions and billions of discarded plastic bottles every year, textile researchers have just discovered a great solution to make Bulk Continuous Filament (BCF yarn) from recycled PET (polyethylene terephthalate) bottles. 100% v-PET compact spun yarn has higher tensile strength with the value of 39% than 100% r-PET compact yarn. It takes about 9 bottles to make one T-shirt. Textiles currently make up the largest share of virgin PET production globally. There are plenty of people developing technologies to recycle polyester fabric or textiles in general, like the UK-based company Worn Again, or the US-based companies Ambercycle and Tyton Biosciences (just to name a few). As long as this is the case, the reliance on petroleum will remain high. It was the company’s continued investment in research and development that brought a high-tech yarn to life. It is estimated that in 2016 2.9 billion plastic bottles were diverted from landfills to be recycled back into polyester yarns. Finally, they are formed into threads of different shaped and thickness. One of the examples in the textile industry are polyester filament yarns made out of recycled plastic bottles. One thing increasingly noticeable on the internet are ads for sustainable clothing made from recycled polyester. Required fields are marked *. This could be displayed to the consumer through an interface, such as a QR code or RFID tag, and hence providing greater transparency on its origin. These tracers enable the fibres to be tested in a laboratory to verify their origin. And they also take up the largest share of recycled PET from bottles. And another idea is that of ‘material passports‘, which could potentially interface with a blockchain-based traceability system. Even if the digital record is legitimate, the physical product may not be. First, the bottles are broken down into small flakes at the Repreve Bottle Processing Center in North Carolina, which can handle around 2.2 billion bottles a year. The extruded plastic is cooled and then thoroughly chopped to make plastic pellets. The pellets are sent to a yarn manufacturing facility where they are melted & spun into polyester fiber. Blockchain can therefore also enable greater transparency for consumers – provided a manufacturer wants to share this information. NewLife is a line of polyester yarns created entirely from recycled plastic bottles.
