Zero Waste Textiles

These countries are home to around a quarter of the global population, yet consume over one-third (34%) of raw materials. Shift countries’ material footprint per capita is 4.6 times that of Build countries (largely due to the overconsumption of consumer goods imported from Grow counties) and 1.6 times that of Grow countries.

These are high-income countries in the Global North, as well as in the Gulf, Australia, and Oceania. Examples include:
- Member States of the EU
- the US
- Japan
- the UK
- Canada
- Argentina, ...

While much of their infrastructure is already built, they still contribute heavily to the overshoot of planetary boundaries: they contribute 42% of climate change, 27% of nitrogen, 18% of phosphorus, 16% of freshwater use and 38% of land use change.

Shift

Business

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.

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

Urban Opportunities

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.

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.

Climatex

<p>Climatex, a company that produces regenerative, sustainable textiles, develops all its products to follow the Cradle-to-Cradle principle. The brand uses nature as a role model, turning waste into a resource: all products return to the cycle of manufacture, consumption and renewal at the end of their functional lifetime. The system uses natural resources efficiently and responsibly, and protects ecosystems through the use of renewable forms of energy. At end-of-life, climatex products are returned to their cycles as biological nutrients and synthetic fibres, through the development of cyclical metabolisms that allow for natural production methods and constant reuse. Materials that can be categorised as ‘biological nutrients’—those suitable for biogas harvesting or composting—are used exclusively. Only safe chemicals are used, and the proportion of polymers in the fabric allows for complete decomposition into basic chemical components, facilitating easy reuse in other products.</p>
