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:

VISION:
Raw materials are renewable, recyclable and safe, kept in continual circulation.

DETAIL:
Imagine a time when…the raw materials that are used to make things are sourced from existing products and regenerative agriculture, via carbon negative and climate neutral processes. Biodegradable raw materials are used for products with biodegradable end routes. Toxic chemicals have been washed out of the global materials pool, disposed of safely and replaced with beneficial alternatives. Virgin fibres made from fossil fuels have been banned, while secondary synthetic fibres, derived from what was already in the system, are kept in constant circulation as a resource. Circularity accounting methods, built on science-based metrics, help to manage a balanced system of resources, across all industries, and in line with the planet’s environmental limits.

Raw Materials and Planetary Boundaries

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.

Products and Services

VISION:
People are valued and supported in an equitable, socially just and resilient society.

DETAIL:
Imagine a time when…people and communities are at the heart of any sustainable and circular system. The planet thrives, enabling us to survive with balance and abundance. People are no longer passive consumers, but proactive participants. The ‘makers’ who design, build, reprocess and recirculate products throughout the value chain are treated equally and are equitable partners in shaping and benefitting from the system. Textiles/garments can be produced and repurposed locally as well as centrally. A blend of craft methods alongside more automated production provides regionalised, multi-faceted perspectives and fulfilling livelihoods, be they high- or low-tech. Wealth gaps are minimised and dignity, equity, equality is a reality for all.

People and Society

Regenerate strategies phase out hazardous or toxic materials and processes and substitute them with regenerative biomass resources. A circular economy aims to mimic natural cycles—by shifting to more regenerative farming practices, for example—while also maximising the share of circular biomass that enters the economy. Regeneration can happen both at the systems level (by designing regenerative processes) as well as at the product level (by switching synthetic to organic fertilisers, for example).

Regenerate

Cycle strategies aim to cycle and reuse materials at their highest value: they maximise the volume of secondary materials re-entering the economy, ultimately minimising the need for virgin material inputs and therefore also narrowing flows. Of course, virgin materials will always be needed to a degree: all materials degrade and can’t be cycled infinitely, use energy, and require blending with virgin materials to maintain strength and functionality.

A framework of policy instruments that enable and stimulate the transition to the circular economy

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.

Circle Economy's framework of strategies and activities that define the circular economy

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 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.

REFLOW was an EU Horizon 2020 innovation action project running from 2019 to 2022, with the aim to increase circularity in European cities. Through REFLOW, the 28 project partners developed a range of solutions to make the material flows more circular within the six pilot cities of Amsterdam, Berlin, Milan, Cluj-Napoca, Paris, and Vejle. The cities' social, environmental, and economic impact was assessed, and a range of solutions enabling the circular transition were developed through active citizen involvement. The project combined the expertise of the project partners spanning municipalities, scientific and research institutions, technology providers, design and grassroot organisations, and small and medium-sized enterprises.

Circular food systems entail that the food is produced regeneratively and, where appropriate, locally. Food and packaging waste are designed out entirely, while healthy, low-impact diets are promoted and easy to access. 

[Circle Economy](https://www.circle-economy.com/) is a not-for-profit organisation working to accelerate the circular transition. Through the *Circularity Gap Reporting Initiative*, our mission is to deliver an annual global Circularity Metric that measures the state of the world economy and identifies key levers to transition to global circularity. With nature as our guide, we work alongside cross-sector stakeholders from academia, businesses, NGOs and governments to provide a powerful combination of practical and scalable interventions that transform circular opportunities into realities.

Milan

During its participation at the REFLOW project, Milan focused on specific food flows to test new food prototypes, support existing projects that transform food waste into new products, and enable initiatives that focus on reducing food waste at the wholesale and market stage.&nbsp;&nbsp;

Milan Food Policy involves 10 dimensions: governance, education, waste, access, wellbeing, environment; ecosystem of agriculture; production; finance and commerce. The design of the policy has involved a public consultation among citizens. It has information campaigns focused on promoting healthy and sustainable food habits, better use and conservation of food. Moreover, it supports research institutions in the process of identifying national, european and international funding sources, in the creation of an academic network for sharing knowledge nationally and internationally and in the promotion of partnership between organizations involved on research.Milano won the Earthshot Prize 2021 thanks to its innovative food policy, that aims at halving food waste by 2030. The&nbsp;Earthshot&nbsp;Prize rewards&nbsp;the city’s commitment towards a more environmentally-friendly urban future&nbsp;and its role of global leader in the fight against climate change. Milan’s&nbsp;neighbourhood hubs against food waste&nbsp;were launched in 2017. The goal of the&nbsp;project&nbsp;is to halve food waste by 2030.&nbsp;The hubs collect surplus&nbsp;food&nbsp;from supermarkets and office canteens and then donate it to charities and NGOs,&nbsp;who distribute it to the neediest citizens.

Milan Food Policy

A number of regions in Italy have significantly increased bio and organic waste separation by transforming their waste collection systems. A group of Italian cities and regions including Milan, Parma, Sardinia, Treviso, and Capannori, within a few years have significantly improved their systems, and in doing so, have saved money, created jobs, and reduced environmental impacts.In the case of Milan, back in 2011, the city started implementing an ambitious scheme to separately collect bio-waste and recycle it back into local soil or use it to make biogas. With 1.4 million inhabitants in an extremely densely populated area, Milan is now one of the leading examples in Europe of how to design and implement an effective system. After a decade of implementation, in 2019 the system collected 95 kg of bio-waste per inhabitant with a contamination rate of less than 5%, whilst the city also had a total municipal waste separate collection rate of 62%.&nbsp;

Bio-waste collection in Italy

The Municipality of Milan works together with the Distretto Agricolo Milanese (DAM), a consortium that brings together over 30 farms surrounding Milan, to support procurement of locally sourced food. For example, the rice served in Milan school canteens is entirely produced by the DAM and to date, 19 other horticultural supply chains have connections to local sources of food production, drastically cutting down on transportation and supporting local production.
