Circle Economy and ICLEI have partnered up to initiate the go to knowledge hub of case studies about the circular economy in cities. The Cities Collection is a repository of case studies that demonstrate the role of cities in the circular transition, and includes policies, business cases and research articles. Cases in the Collection flow into an ecosystem of digital products which support users in transitioning cities to circularity, for example [Ganbatte](https://ganbatte.world/cities/) and <a href="https://circulars.iclei.org/" target="_blank">ICLEI Circulars</a>, both part of the <a href="https://circulars.iclei.org/circle-lab-for-cities/" target = _blank">Circle Lab for Cities Programme.</a>

Recover

The built environment, including housing, commercial buildings, and the necessary infrastructure for mobility, is essential for our livelihoods, but:
- the extraction of minerals used to produce construction materials is responsible for a quarter of global land use change,
- approximately 40% of global GHG emissions can be attributed to buildings’ construction, use and demolition, and
- construction and demolition processes drive nearly one-third of all material consumption. 

Making the built environment more circular must prioritise a heavy reduction in material use—while also closing the loop on materials and bringing secondary and renewable material choices to the fore. Our four key solutions for the built environment are:
- Make the most of what already exists: Make the most of existing materials by reusing, repurposing, upgrading and renovating following circular approaches. Where new builds are needed, use secondary materials and be as efficient as possible with urban planning solutions that follow circular design principles so that buildings can be reused, repurposed, and easily disassembled in the future.
- Be as energy efficient as possible: From the design phase, utilise circular strategies to create material- and energy efficient buildings. Couple these designs with a rollout of clean energy solutions, and prioritise energy-efficient appliances and retrofitting. 
- Utilise secondary materials: Maximise the high-value reuse of buildings and components where possible. Ideally, enable the utilisation of construction and demolition outputs and ensure that as much of it as possible is recycled to avoid the need for virgin materials, such as sand and gravel.
- Prioritise circular materials and approaches: Transition to using renewable wood, timber or cross-laminated timber instead of steel and concrete, or move to other locally available materials. Utilise mainstream modular construction and prioritise lightweight frames and structures to reduce cement and steel use, as well as green roofs where possible.

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.

The Circular City Actions Framework provides urban changemakers with five complementary strategies they can use to start working towards a more circular system. 

The framework is action-based to provide users with concrete strategic directions and showcase the desired outcomes of each strategy. 
The framework consists of five complementary **strategies**, under which **sub-strategies** provide further detail. Finally, each sub-strategy consists of a diversity of tangible **solutions** which are framed in relation to key thematic areas. 

Note: solutions are currently focused on:
- 🍏 **Food systems**
- 🏢  **Built environment**
- 👕📱  **Consumer goods**
- ⚡ **Energy Systems**
- 🚌 **Mobility Systems**
- 💧 **Water Systems**

More thematic areas are coming soon...

Thematic Areas

City Stakeholders

  Our research outlines key principles of the circular economy, using the Ellen MacArthur Foundation’s ReSOLVE framework to explore and contextualise practical applications in the built environment.  We identify how the circular economy can benefit Arup, our clients, and the built environment sector. We reflect on the economic, social and environmental advantages of employing circular principles. And we propose strategies to progress our offering, deliver new services, engage a wider network of stakeholders and unlock opportunities for all parties in the value chain. We also consider how circular economy practices can be scaled up from the individual component or asset level for city, regional, and even global economies. We believe the circular economy can enable Arup to tackle the complex nature of the built environment through multidisciplinary working, and that it can drive a shift towards more sustainable forms of economic growth, urban life and value creation.

As the Ellen MacArthur Foundation’s knowledge partner for the built environment we are sharing knowledge and collaborating with our CE100 partners to accelerate the shift to a circular economy.

We’re a charity committed to creating a circular economy, which is designed to eliminate waste and pollution, circulate products and materials (at their highest value), and regenerate nature. It’s an economic system that delivers better outcomes for people, and the environment.

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.

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.

  This research jointly written by Arup and BAM explores ways Circular Business Models (CBMs) would provide added benefits throughout the value chain in construction.
By highlighting the value proposition to all stakeholders, it is intended that more companies will see the benefit of a built environment based on the circular economy. Circular Business Models cannot be achieved without intervention, as in today’s economy there are numerous examples of where it is currently perceived as more cost effective and convenient to dispose of resources after their first use rather than re-use them. By taking a systemic view across the whole life cycle of assets, using new technologies and applying advance design approaches, additional value could be created. This value will demonstrate an economic business case for adopting CBMs, as well as providing wider global benefits from a financial, social and environmental standpoint. Funders, owners and occupiers will be fundamental to driving a ‘circular built environment’, by choosing to adopt alternative development strategies, ownerships structures and operations models. However architects, designers, engineers, suppliers, contractors and facilities managers will have a crucial role in creating circular solutions to facilitate a move to CBMs.

The content of this report is applicable to the built environment as a whole, but many of the examples cited focus on commercial building developments. The general principles are the same for other project types, i.e. infrastructure/PPP, although the use periods, ownership models and supply chain interactions differ accordingly.

Royal BAM Group nv is a construction firm with operating companies in five European markets (the Netherlands, Belgium, the United Kingdom, Ireland and Germany). BAM’s operating companies are active in the business lines Construction and Property, Civil engineering, as well as in Public-private partnerships.

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:

This collection features a selection of case studies, mainly based on the [2024 Circularity Gap Report](https://www.circularity-gap.world/2024). 

In this year’s Report, we shift from exploring the what to the how: exploring the different ways that we need to ‘change the rules of the game’ and create a set of conditions that discourage the overshoot of planetary boundaries and ‘undershoot’ of human development. This process has resulted in us spotlighting 12 of the original 16 solutions, highlighting the country profile that they are most relevant to, as well as placing people at the centre of this story for the first time. Based on extensive interviews and desk research, this Report aims to show governments and industry leaders that if they want to turn theory into action and scale an economy that delivers on needs within the safe limits of the planet, they need to dismantle harmful entrenched processes and align enabling elements. 

[Circle Economy](https://www.circle-economy.com/) is a global impact organisation with an international team of passionate experts based in Amsterdam. We empower industries, cities, and nations with practical and scalable solutions to put the circular economy into action. Our vision is an economic system that ensures the planet and all people can thrive. To avoid climate breakdown, our goal is to double global circularity by 2032. 

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. 

To learn more about these interventions to accelerate the circular transition, read the [latest Circularity Gap Report 2024](https://www.circularity-gap.world/2024), as well as previous editions of the global [Circularity Gap Reports](https://www.circularity-gap.world/global).
