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>

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.

Rethink

High-level changes to policy and practice (such as taxation systems, investment and procurement guidelines and criteria) that disincentivize activities that perpetuate linear economic systems, as well as vision-setting (goals, roadmaps) to catalyze
action on circularity across the city

Eliminate linear incentives and set goals and incentives for circularity

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.

When organic wastes are landfilled, the value and nutrients are lost and irrecoverable. Landfilling also causes additional environmental pressure, for example, the decomposition of food and organic waste in landfills emits greenhouse gases into the climate. Reducing the space required for landfills creates opportunities for better use. 

Local governments have an important role to play in the elimination of the landfilling of organic wastes. Municipalities with the legislative authority to do so can introduce legislation that bans organic wastes from being landfilled and fines non-compliance.

Municipalities can ensure that municipal organic wastes are collected and diverted from landfill by mandating certain processing techniques, for example, composting or anaerobic digestion.
