This collection has been built by a community of passionate researchers, students, and industry professionals as part of <a href="https://worldcirculartextilesday.com/" target="_blank">World Circular Textiles Day</a> (WCTD). 


World Circular Textiles Day takes place every year on 8th October. Our vision is to galvanise the collective ambitions and goals of people, organisations and businesses to reach a fully circular textiles world by 2050. Our mission is to provide a framework for circularity stakeholders to develop and deliver a collaborative, evolving roadmap and to chart circularity’s momentum annually from the 8th of October until 2050.

What does fully circular by 2050 mean?
- Shared textile resources, in the form of products and raw materials, are kept in **continual circulation**.
- Virgin resources are **replaced with circular materials**.
- Dignity, equity, and equality for the **people** involved in all parts of the circular value chain.

We need to know where we stand today to chart how to get to 100% Circularity by 2050. What circular activity is currently happening in the textiles and apparel industry, and where in the world is it happening? The WCTD Collection aims to answer this question by building the world’s largest digital library of circular textiles case studies. 

World Circular Textiles Day is proud to be supported by our 2022-23 Circular Hero Partners:

Business case

Reduced use of virgin materials and/or an increase of the use of secondary and bio-based materials

Reduce Material Consumption (SDG12)

Minimise waste through diversion: Instead of sending waste to landfill, it is redirected into other industrial processes for handling, treatment, recycling, recovery, or reuse in various forms. 

Minimise waste through design: At the outset of a process of project, plan and design such that there is zero waste or minimal waste during production, use, and at end of life. 

Minimise Waste (SDG12)

Producing textile and leather products and processing them into apparel and accessories

Fashion and Textiles

Using waste materials that have been processed and recycled to produce new products within the same industry

Using closed loop recycled materials

VISION:
Products and services are designed for multiple use and material value retention, with maximum positive impact.

DETAIL: 
Imagine a time when…products flow via optimal collection and distribution streams into reusable and repairable product platforms. Reuse and access models are dominant, and products are designed for multiple recirculation before biodegrading (if designed to do so), or being broken down into reusable raw materials for production. People only consume what they need. Production and consumption wastes have been fully eliminated and multifunctional, season-less and timeless fashions are the norm, yet still fulfil our human need for expression and creativity without constraint. All business models, organisations, governments and citizens play a role in maintaining a healthy, functioning circular ecosystem.

The principles of a circular economy concern designing out waste, regenerating ecosystems and keeping items in use. Decoupling the economy from material flows—improving the rate of resource productivity faster than the economic growth rate—is also a consistent guide. By evolving with the growing number of applications of circular economy principles, and consolidating these strategies across thematic areas, Circle Economy’s Key Elements Framework (KE) renders the elements of the circular economy salient and serves as a basis to derive contextual strategies and interventions. 


The Framework consists of:
- Core Elements: Activities directly handling product or material flows; and uniquely,
- Enabling Elements: those that remove obstacles for core actors.

Topics

Urban Opportunities

Whilst no two countries are the same, there are still obvious similarities between some of them, with discernible development patterns and parallels in evidence. Common problems and shared solutions help place unique country identities and individual issues in context.

Whilst this classification is far from clear-cut and exhibits some overlap, it does underline how the discourse on transitioning to a circular economy needs to account for both differences and commonalities, if we are to arrive at a more strategic and instructive analysis. It also allows to highlight a set of key themes that are likely to be central to the countries that fall under the respective profiles.

Implementing stakeholders

It is 2050.  Full systems change has taken place. This wouldn’t have been possible without the immediate action and radical steps taken from 2020 onwards. Many targets had to be identified in the early 2020s and achieved by 2030 to ensure that the 2050 goal happened in full. A sense of urgency, turbo stakeholder collaboration, supportive government regulation and clear, data driven targets enabled the mindsets and systems change needed to transform to a fully circular textiles ecosystem.

A circular economics model underpins what we have created. It reflects and supports a living organism made up of makers, users and restorers, interacting across vibrant and interconnected networks. Checks and balances, alongside transparency and accountability, ensure a healthy system. Financial, environmental, and social metrics have the purpose of serving communities and the planet. There is shared ownership of profit and loss – across all three metrics – throughout the value chain.

This is what we’ve achieved over the last 30 years:

Based on the ongoing ISO standardisation process, a taxonomy has been defined under which to cluster indicators to measure circularity. 

ISO Taxonomy

If managed well, the transition to the circular economy will have multiple benefits for the labour market, including the opening up of job opportunities, raising job standards and reducing inequalities through a global redistribution of value. But a positive transition to circularity for work and workers must be underpinned by three pillars: upskilling the workforce, quality of work and inclusive job opportunities. Find out more and explore cases that illustrate these pillars below.

This is a survey that dives into understanding the policy environment around specific circular solutions. 

The survey is divided into five sections, based on the five key elements of the Circular Cities Action Framework. 
Each section asks 2-3 questions to explore which policies may or may not be present within your city to support a transition towards a circular economy. 

You are not alone! Each question provides some practical examples from cities around the world that have adopted a certain policy to support their transition. This can help to compare with your city - is your city doing something similar?

The survey answers should be based on your current knowledge, and not illicit additional research - ! Please make use of the Not sure option as appropriate.

Based on the work of [Bocken et al. (2016)](https://www.researchgate.net/publication/309699661_Product_design_and_business_model_strategies_for_a_circular_economy), the Four Flows Framework serves as a simple framework for managing resource flows in a circular economy by using less (Narrow), using for longer (Slow), using again (Cycle), and using clean, regenerative materials and energy (Regenerate).

These different principles of circular economy can be applied to our socioeconomic metabolism: we can design stocks like buildings, infrastructure, machinery, and vehicles to be rich resource mines for the future, and design manufactured goods and consumables to be cycled and made regenerative. Furthermore, the focus must also centre on getting more value out of fewer materials. Achieving the aims of a circular economy—minimising material use, regenerating the Earth, and preventing material losses—can be done through these four key strategies mentioned above.

Spin yarn from used clothesClose the loop in the textile industrySpin ring and rotor yarnsSet new standards in spinning post-consumer materialClimate change and environmental degradation are some of the main concerns facing us today. With barely 1% of garments being recycled and three quarters of the world’s clothing ending up in landfill, the textile industry is actively seeking ways to make production patterns more sustainable and pay more attention to the entire life cycle of items of clothing. Rieter is actively committed to a sustainable policy, using its technological expertise to offer a complete recycling spinning system for both ring and rotor spinning lines that enables customers to spin fibers from used garments and waste into yarns.One of the goals within the textile industry is to “close the loop,” which refers to the process of recycling and reusing products without material loss – or, in other words, using less raw material and diverting waste away from landfill.This would entail, however, solving one of today's main challenges: recycling pre- and post-consumer goods. Until recently, recycled clothes have been used mainly into lower-value applications. Rieter's technological know-how enables yarns of sufficient quality to be produced for use in weaving and knitting applications, thus finally allowing pre- and post-consumer goods to be recycled in similar applications.Rieter is committed to close the textile cycle. Check out the results of our latest study on how to spin not only rotor, but also ring yarn with a considerable amount of post-consumer material on your Rieter system. Explore Rieter has optimized the rotor spinning technology, which is naturally adapted for applications using materials with short fibers. Special geometries and options allow for optimized adaptations. The fully automated machine combines high potential for yarn tenacity with the capability to handle many ends down with excellent piecing quality. As a result, using Rieter's recycling system on a rotor spinning line makes it possible, for example, to spin yarn up to Ne 20 with a blend of 75% post-consumer material and 25% virgin cotton, or yarn up to Ne 30 with a blend of 87,5% pre-consumer material and polyester.Nowadays, recycled yarns are rarely produced on ring spinning lines. Rieter offers a complete system that is designed to process short fibers in the best possible way. Despite the presence of very short fibers from the recycled post-consumer branch, the yarns obtained can be used in weaving and knitting applications. Using Rieter's recycling system makes it possible, for example, to spin ring yarn up to Ne 20 with a blend of 60% post-consumer material and 40% virgin cotton, or yarn up to Ne 30 with a blend of 60% pre-consumer material and 40% polyester.All machines can be adapted to the properties of recycled raw material. Check out the features of the card C 80 and the roving frame F 40.Largest total carding area40 working flats and the longest pre- and post-carding zone enable intensive opening, also of yarn and fabric remnants.Optimal preparation by licker-inThe licker-in removes unopened material, which can still be present after the tearing process. For most recycled material, the sawtooth clothing is recommended.Special Graf clothing setsThere are special Graf clothing sets for the different requirements. For recycled raw material, usually the flexible flats are used; for special cases, the semi-rigid flats are recommended.Easy cleaning thanks to modular designResidues of colored recycled material can be quickly removed from the web bridge, thus ensuring a perfect web.Top roller cleaning device with feltThis optional device takes up the fluff from the top rollers. With the integrated metal comb on top of the felt, the fluff is collected at a specified place and removed by the OHTC suction nozzle.Overhead Travelling Cleaner (OHTC)The OHTC removes the accumulations from the cleaning felt and reduces fiber fly, which is crucial for materials with a high short-fiber content.Suction for table cleaningRecommended option to control fiber fly in the drafting zone. Defined nozzles of the OHTC blow the fluff towards suction funnels below the drafting zone, resulting in a constantly clean flyer table.The good pilling values of yarns from the Rieter recycling system make many different applications possible, from socks to sweaters. Chinos and workwear can be made out of recycled materials too. Chino pants like these are typically made with a blend of recycled cotton and virgin cotton.Recycling journey:A second-hand T-shirthas its material torn to tear fibersand recycled into high-quality yarnsto produce a chino pant.To help spinners work with recycled fibers, Rieter has established a recycling classification system for the typical raw-material quality available on the market. The Rieter recycling classification makes it easier for spinners to estimate what targets can be reached depending on the material. The short-fiber content, mean fiber length and 5% fiber length are important parameters after the tearing process because they determine which subsequent spinning process (ring or rotor) should be used and which quality (uniformity) and maximum spinning fineness (yarn count) can be achieved. ClassificationSHORT-FIBER CONTENTMean Fiber Length5% FIBER LENGTHVery good45%17 mm31 mmGood55%14 mm29 mmMedium60%13 mm28 mmPoor78%10 mm22 mmCotton as reference24%21 mm34 mmA complete Rieter system is established on Rieter’s expertise throughout the entire spinning process: from processing raw material to yarn. Experts offer a wide range of services. The entire spinning mill is networked and controlled from a single platform with ESSENTIAL – Rieter Digital Spinning Suite. This guarantees high quality and optimal efficiency, both now and in the future.The blowroom line VARIOline is the variable concept for optimally opening and cleaning fibers. This guarantees the highest level of yarn quality. All blowroom machinery is designed to support an impressive line production performance of up to 2 400 kilograms per hour. VARIOline consumes around 40% less energy than solutions from other providers.  Explore The high-performance card C 80 produces 30% more card sliver compared with the current benchmark. The C 80 card runs with high productivity, sliver quality and raw material utilization thanks to a maximum-sized technological carding area. The C 80 is easily accessible and has straightforward maintenance requirements.  Explore The double-head draw frame without autoleveler SB-D 26 is a highly efficient machine. It delivers up to 33% more sliver compared to the previous model and, with a width of just 3.38 m, is the most compact draw frame in its class. The drive concept ECOrized requires 25% fewer belts, saving energy costs.  Explore The double-head autoleveler draw frame RSB-D 26 combines the highest levels of sliver evenness and productivity using two heads that are completely independent of each other. Depending on the raw material, the RSB-D 26 produces up to 33% more sliver compared to the previous model. Explore The direct connection of the card with the new autoleveled draw frame module RSB-Module 50 reduces the number of draw frame passages and improves the efficiency of the spinning mill. Explore The new generation of roving frames produces first-class rovings with low conversion costs. The fast doffer installed in the F 40 ensures a high level of efficiency. With up to 252 spinning positions, the machine is ideally suited to long ring-spinning machines. Explore The ring spinning machine G 38 with the fully electronic drafting system allows an extraordinary flexibility. Standard and special yarns as well as compact yarns can easily be produced. The individual spindle monitoring system ISM premium reduces about 5% of personnel costs.  Explore The fully automatic rotor spinning machine R 70 sets new standards in terms of its high productivity, improved raw material utilization and low energy consumption. This is achieved by incorporating independent, state-of-the-art automation at every spinning position as well as an advanced version of the proven spinning box technology.  Explore The rotor spinning machine R 37 has a new spinning box with adaptable trash extraction to provide more flexibility in raw material use. With up to 600 spinning positions, low energy consumption and time-saving handling, the R 37 is particularly economical. Fully independent machine sides provide high flexibility.
