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>

Business case

Impact on increased knowledge and understanding as a result of the case study

Increase Awareness

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)

Processing and producing food and beverages for consumption

Food and Beverage

Using materials that can be easily reused or recycled after use

Reusable, recyclable materials and inputs

'Inform' increases the overall levels of awareness and builds the necessary skills and knowledge around the circular economy to foster long-term change.

Inform

'Manage' influences the use and function of physical and material elements within the urban environment. 

Manage

Infrastructure

Develop infrastructure to support resource cycling

Use longer and more often by extending and intensifying use of existing resources, products, spaces and infrastructure

Reuse

Incorporate extended use in project planning phases; create or update city policies to allow for extended use.

Design and regulate for extended use

The food system nourishes populations and employs 50% of the global workforce, but:
- it currently drives a quarter of the overshoot on the climate change planetary boundary due to its greenhouse gas (GHG) production, 
- animal farming alone uses over one-quarter of all land, equivalent to the size of the Americas,
- nearly a quarter of freshwater resources are lost due to rampant food waste, and
- it is the single largest driver of biodiversity loss.

A circular food system must address the whole value chain, from production to consumption to waste management. The four key solutions for the food system are:
- Put healthier, satiating foods first: Prioritise satiating and healthy foods with a lower environmental impact—ideally shifting calories from meat, fish, and dairy towards cereals, fruits, vegetables, and nuts.
- Go local, seasonal, and organic: Prioritise the production and consumption of local, seasonal, and organic produce (sometimes in combination with GMO to reduce pests and disease loss on crops), which can lead to a significantly reduced need for chemical inputs, fuels, and processing services that contribute to environmental impacts.
- Mainstream regenerative agriculture: Scale up agricultural practices that regenerate ecosystems, recirculate nutrients and sequester carbon by design. 
- End avoidable food waste: Minimise food loss and valorise waste following the food waste hierarchy along the supply chain and at the consumer level through better management of transport and storage, more refrigeration and smart planning, and technology at the consumer and food service levels.

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

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...

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.

We are ever so grateful and impressed by the enthusiasm with which our Toronto community embraced Wisebox and supported efforts to make Toronto cleaner, greener and more sustainable.Wisebox was the first reusable takeout container program for Toronto's restaurants and cafes that provided consumers a waste-free option for takeout.Toronto has shown that it wants and is ready to tackle the single-use disposables, and together we proved that waste-free take out is possible. While the pandemic has reshaped our realities, health professionals have reassured us of the safety of reusables, and we trust that Toronto will continue to be a leader in the reusables movement. The Wisebox pilot was a great opportunity to test the model, and the lessons learned will help us continue our work to make sustainability the norm in Toronto. We have enormous gratitude for the forward thinking restaurant partners that worked with Wisebox to launch the first reusable takeout container program in Toronto. Please continue to show them support during these challenging times.We look forward to continuing to work with our friends in the sustainability community towards a low-waste circular economy in new ways.Remember: we can use the collective power of our buying choices to cast a vote for a healthy future, and our great city, Toronto, provides many ways to show our love for planet earth. We look forward to crossing your path in those second hand shops, refill and package-free stores, and in share and repair spaces. Stay strong!If you would like to connect with the former Wisebox team to learn more about the project, complete the form below.

Wisebox

<p>Wisebox was the first reusable takeout container program for Toronto's restaurants and cafes&nbsp;that provided consumers a waste-free option for takeout. The Wisebox pilot launched in February 2020 and conducted a test run for 4 months. The pilot project allowed customers to order their meal in a Wisebox reusable container from a restaurant partner just by paying a deposit in addition to the menu price. Customers could then return the container to any participating location to exchange it for a new one, or to receive the deposit back in full. Or simply wash the container and have it refilled. Although the pandemic reshaped the conditions for the project to work and put an end to the pilot, the initiative has demonstrated that safety of reusables and waste-free take out are possible. The lessons learned will help continue the city's work to make sustainability the norm in Toronto. If 1% of Torontonians would use Wisebox, more than 1 million disposables could be offset in one year.&nbsp;</p>
