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>

Support local low-impact circular economies

Cities consume about 75% of global energy and emit between 50% and 60% of global greenhouse gases (UN-Habitat). To reduce the negative impact of their energy consumption, cities need to shift away from fossil fuels and move towards renewable energy sources. Such a shift will help cities work towards their climate change mitigation and adaptation action plans. Renewable energy technologies such as wind, water, solar, and geothermal can also help improve access to energy in vulnerable and marginalised neighbourhoods through, for example, decentralised, off-grid solutions.

Renewable energy technologies can harvest the energy in nature’s processes, such as wind, and solar radiation and geothermal heat, that can be replenished within a human lifespan. In contrast, fossil fuels are materials that are not replenished within a human lifespan and are combusted for energy, losing the fuel material and resulting in emissions.

Local governments can develop sustainable energy plans, considering different energy resources and requirements, to develop a robust strategy for the development of renewable energy technologies and infrastructure throughout the city. They can also institute specific legislation and tax systems to regulate energy production and consumption, incentivise research and development of cleaner, more efficient technologies. Via Power Purchase Agreements cities can buy renewable energy from green energy providers and fix the price in order to provide security to financial institutions to finance renewable energy infrastructure. Furthermore, increasing awareness and facilitating capacity-building on planning urban sustainable energy projects can help the uptake of clean energy across the city by different stakeholders—from citizens to businesses and institutions. Facilitating collaboration, then, will be crucial, since private companies operate most of the world’s energy systems.


⚡ Energy Systems

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.



🏢 Built Environment

Manufactured goods, such as vehicles, textiles, appliances and equipment and their associated production processes are big employers but:
- production processes often rely on fossil fuels and currently drive one-third of the overshoot on the climate change planetary boundary due to its GHG production, 
- material- and energy-intensive industrial activities are linked to deforestation and drive 15% on both the land use and freshwater planetary boundaries, 
- manufacturing goods results in substantial amounts of hazardous industrial waste and leaks chemicals into the environment.

Here, circular solutions must tackle the full value chain, but material demand must also shrink: this will necessitate a societal shift to favouring sufficiency over excess and reducing consumption to sustainable levels. Our four key solutions for manufactured goods are:
- Mainstream industrial symbiosis and efficiency : Achieve process improvements, scrap diversion and reduction in yield losses through greater industrial symbiosis and efficiency. Foster tighter collaboration within and between industries to deliver powerful material and emissions savings.
- Extend the lifetime of machinery, equipment, and goods: Maximise the lifetime of goods that serve our daily needs to bring a number of environmental benefits. 
- Buy what's needed: Reduce the number of purchases of common electronic goods, appliances, and other equipment to sufficiency levels. 
- Eschew fast fashion in favour of sustainable textiles: Drastically reduce new clothing purchases. All used clothing should go on to be repaired, reused or, if needed, recycled appropriately. Prioritise natural and local textile manufacturing, as well as higher-quality and more durable garments. 




👕📱 Consumer Goods

Businesses

Governments

Consumer goods are typically fast moving through the economy, meaning they are produced and disposed of in a short space of time. This has led to consumer goods being responsible for significant quantities of avoidable waste generation, often consisting of materials that cannot easily be recycled, and often end up polluting the environment.

A local government can consume less goods in the first place, which allows the waste generated to be reduced significantly, and reduces environmental pollution. Many consumer goods can be made more durable, allowing for multiuse rather than continual procurement of new goods. One such example of ths is reusing uniforms used in some public sectors (e.g. police service), rather than unnecessarily procuring a new set for every new employee.

Local governments can reduce their consumption of consumer goods in their city by creating awareness campaigns about overconsumption and the idea of ‘doing more with less’, where appropriate. Local governments can also directly reduce their consumption by pursuing a green public procurement policy. This is a process in which a local government prioritises the procurement of goods and services with the lowest environmental impact. In many cases this yields the procurement of less goods by purchasing more durable alternatives or reusing existing resources.

👕📱 Reduce consumption of new consumer goods by local governments

Slow strategies aim to keep materials in use for as long as possible, for example through design for durability and repairability. A more circular economy is also a slower one: materials, components, and products—and even buildings and infrastructure—that we lock in stocks are made to last. This will lower material demand in the long run, in essence also serving to narrow resource flows.

Slow

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.

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.

 The Circular Rotterdam report, commissioned by the City of Rotterdam and produced by Metabolic in partnership with Circle Economy, Blue City and Spring Associates, was produced to inform the city’s efforts to create 3,500 to 7,000 new jobs and reduce material consumption by 50% by 2030 in the creation of a circular economy.
The report highlighted that construction waste in particular represents not just an environmental problem, but an opportunity: that just as Rotterdam is currently known as a world leader in modern architecture, it could also become renowned for making the most of the waste produced by the city’s heaving construction activity.
According to our sustainability consultant and co-author of the report Pieter van Exter, there are huge potential benefits to harness the city’s construction waste, which in 2015 consisted of 393,783 tonnes of pulverized concrete, bricks, and other materials – the equivalent of 58 Erasmus Bridges.
“With its harbor and strong culture of designers and architects, Rotterdam has a unique opportunity to become truly circular in the coming decades, closing loops on local, regional, national and international levels,” he said.
“But to be truly circular by 2050, we have to start today!”

Metabolic analyzed waste streams from Rotterdam’s construction, food and energy, consumer goods, and healthcare sectors. The waste is not just represented in the raw materials itself, but in the energy and embodied impacts related to the production of the materials: concrete is the largest consumer of energy in the construction sector by mass.
The report found that reducing the city’s 350,000 tons of construction waste is possible by building houses and offices:

in a way that allows for easy disassembly or renovation instead of demolition;
using sturdy, long-life materials;
reusing materials and components in a way that construction and demolition is connected.

The construction industry was just one of four sectors examined by the report, which found that overall, Rotterdam recycles 22% of its solid waste.

Circular opportunities for food and energy streams, consumer goods and healthcare
For the reduction of food waste, the most impactful stream in terms of water and land use, prevention is an important strategy. The city wastes 14% of food compared to the Dutch national average of 12%.
Only a small proportion of organic waste is currently collected separately to produce biogas and compost, but if separate collection is expanded then up to half of current organic waste could be diverted into creation of new products.
In terms of consumer products, currently 30% of the total mass is collected separately and recycled. This could be substantially boosted through redesigning and promoting alternatives that use fewer materials, and the construction of an Upcycle Mall with specialized recycling facilities for different types of waste. The fact that the majority of the consumer goods are produced for a global market outside of the city and country, makes the influence on these streams of the city small.
Packaging materials account for 35% of all current consumer goods waste streams. This could be reduced by up to 40% by switching to packaging-free stores.
Rotterdam’s healthcare sector, one of the most important economic sectors in the municipality, only represents a small part of the city’s overall waste production, but could reduce its impact even further by expanding preventative care to improve health and recovery during hospital visits.
If Rotterdam can achieve its goal of a fully circular economy, the equivalent of 58 Erasmus Bridges’ worth of waste from the construction industry detailed in the report won’t just be a colorful form of measurement, but an indication of just how many big, new projects the city can embark on with all the materials saved from the scrapheap.
