What is the circular economy?
At its core, the circular economy is a systems-level approach to rethinking how we create and use value. Unlike the traditional linear model—based on extraction, production, consumption, and disposal—the circular economy is designed to eliminate waste, keep materials in continuous use, and regenerate natural systems.
Instead of treating waste as an inevitable outcome, it promotes innovation at every stage of a product’s lifecycle: from responsible sourcing and intentional design to smarter use, reuse, and recovery.
Ultimately, it’s about closing the loop—shifting from a one-way flow to a circular flow diagram of the economy, where resources move in continuous, regenerative cycles.
One of the most comprehensive frameworks to understand this shift is the model proposed by Metabolic and supported by Climate-KIC: the 7 pillars of circular economy. These pillars represent the foundational conditions required to achieve a regenerative and resilient economy—not just in terms of material efficiency, but also in energy systems, human health, biodiversity, and social equity.
Why should outcomes—not activities— define circular success?
As the concept of the circular economy gains traction, the number of definitions and interpretations has exploded. While some consensus is emerging, there’s still a lack of clarity around what “circular” actually means in practice—making it difficult to assess what success looks like.
Many definitions emphasize associated activities—such as leasing models, waste-to-resource strategies, or closed-loop supply chains—but often fail to describe the desired end state of a circular system.
To measure progress and make strategic decisions, we need more than activity-based definitions—we need clarity on the outcomes that a circular economy should deliver. For example:
- Should we prioritize renewable inputs over reuse?
- Is leasing always more circular than ownership?
- Does a recycling process that takes 1,000 years still qualify as circular?
To navigate these trade-offs, we need definitions grounded in performance and impact—not just in activities or labels.
What are the 7 pillars of the circular economy?
Also known as the core principles of circular systems, these pillars provide a comprehensive framework for guiding the shift toward more sustainable, regenerative practices across sectors and value chains.
Here’s what they are:
Pillar 1: Materials are cycled at continuous high value
Instead of degrading resources through downcycling or inefficient processes, this principle emphasizes preserving material complexity. Cascading materials in their most valuable form ensures longer usability, supports repair and remanufacturing, and reduces the need for virgin resource extraction.
Design principle: Preserve complexity through cascading use and modular design.
Why it matters: Enables repair, remanufacturing, and reuse—reducing dependency on virgin inputs and minimizing waste.
In practice: Fairphone creates modular smartphones that users can repair themselves, extending product lifespan and keeping resources in circulation longer.
Pillar 2: All energy is based on renewable sources
Circular economies are powered entirely by renewable energy, with systems designed to minimize energy loss, avoid unnecessary conversions, and favor local, efficient generation and cascading use—like capturing waste heat.
Design principle: Prioritize renewable energy, local generation, and intelligent energy cascading.
Why it matters: Reduces emissions, supports long-term resilience, and aligns business practices with global climate goals.
In practice: IKEA has committed to producing more renewable energy than it consumes by 2030, through global investments in solar and wind infrastructure.
Pillar 3: Biodiversity is supported and enhanced
A regenerative economy actively protects and restores biological diversity. Circular strategies reduce land degradation, avoid ecosystem disruption, and prioritize conservation—especially in vulnerable habitats.
Design principle: Protect and regenerate ecosystems through careful sourcing and land-use practices.
Why it matters: Safeguards the natural systems businesses rely on, particularly in agriculture, cosmetics, textiles, and mining.
In practice: LVMH applies strict sourcing guidelines to avoid harming endangered ecosystems in its global supply chains.
Pillar 4: Human society and culture are preserved
True circularity values cultural diversity and social cohesion alongside ecological sustainability. This pillar emphasizes fair labor, inclusive governance, and respect for local traditions and knowledge.
Design principle: Foster social equity and cultural preservation through participatory, inclusive systems.
Why it matters: Strengthens community resilience and ensures that circular solutions are locally relevant and just. Strengthens community resilience and ensures that circular solutions are locally relevant and just.
In practice: Patagonia collaborates with Indigenous communities to co-design sustainable products that honor traditional knowledge and heritage.
Pillar 5: Health and wellbeing are structurally supported
In a circular system, economic activity must never compromise human or planetary health. Toxic substances are phased out, and processes and products are redesigned for safety and dignity.
Design principle: Eliminate harmful materials and ensure safe, ethical working conditions.
Why it matters: Protects workers, consumers, and ecosystems while reducing long-term health risks.
In practice: Interface, a global flooring manufacturer, removed toxic adhesives and redesigned its carpets for clean, safe recyclability.
Pillar 6: Human activities maximize generation of societal value
This pillar reframes value creation to include emotional, cultural, aesthetic, and ecological contributions—not just financial profit. Businesses are encouraged to generate positive externalities wherever possible.
Design principle: Create value that transcends profit—measurable in environmental, social, and cultural impact.
Why it matters: Builds deeper trust with stakeholders and strengthens community ties.
In practice: Too Good To Go, a social enterprise, fights food waste while engaging communities and raising awareness about consumption habits.
Pillar 7: Water is extracted and cycled sustainably
Water is a finite and shared resource. Circular systems limit freshwater extraction, reuse water efficiently, and recover energy and nutrients from wastewater—while protecting natural watersheds.
Design principle: Use water wisely through closed-loop systems and watershed protection
Why it matters: Especially crucial in water-intensive industries like food, beverage, and manufacturing.
In practice: Unilever has implemented closed-loop water systems in several of its production plants to minimize water use and enhance circularity.
Why every business has a role to play
The circular economy cannot succeed through isolated innovation—it depends on shared direction and collective commitment. That’s where the 7 pillars come in: they offer a common language for companies across sectors to design, align, and scale their efforts.
By anchoring strategies in this outcome-oriented framework, businesses can coordinate action more effectively, accelerate learning, and amplify impact throughout their value chains. Systemic challenges—such as climate change or supply chain fragility—demand systemic responses. The more organizations align, the faster circularity becomes a realistic, scalable path forward.
Ultimately, embracing the 7 pillars isn’t just a matter of environmental responsibility—it’s a strategic step toward long-term relevance and resilience.
Why do these pillars matter now?
The seven pillars of the circular economy provide a clear and actionable framework for addressing today’s most pressing business and sustainability challenges. As organizations face increasing complexity—from climate risks and resource constraints to evolving stakeholder demands—these principles offer a way to rethink operations with long-term resilience in mind.
Rather than incremental improvements, the pillars encourage a shift toward regenerative, efficient, and adaptable systems. They support leaders in identifying new forms of value, anticipating regulatory shifts, and building strategies that perform in the present while laying the foundation for a more inclusive and sustainable future.
The urgency to adopt sustainable models has never been greater. According to the Circularity Gap Report 2023, only 7.2% of the global economy is circular—and this number is declining. Meanwhile, businesses face mounting challenges: climate change, resource scarcity, supply chain disruptions, and growing social inequality.
Linear models based on extraction and waste no longer align with the realities of a resource-constrained world. The 7 pillars offer a systems-based alternative—enabling regeneration, resilience, and long-term value creation.
For businesses, this isn’t just an environmental imperative—it’s a strategic one. Circular principles enable organizations to adapt to complexity, respond to shifting regulations, and meet the growing demand for purpose-driven leadership. By embedding these pillars into decision-making, companies can move beyond short-term efficiency gains and begin creating value that lasts.
Challenges and opportunities on the road to circularity
Challenges | Opportunities |
High initial investment costs | Reduced resource dependency |
Redesign of products and supply chains | Improved brand reputation and stakeholder trust |
Difficulty in measuring multi-dimensional value | Compliance with emerging regulations |

Challenges
Transitioning to a circular economy is not without its obstacles. For many companies, the shift involves high upfront investments, especially when redesigning products, reconfiguring supply chains, or implementing new technologies.
Measuring success is also complex, as circular value spans environmental, social, and financial dimensions that aren’t always captured by traditional KPIs. Perhaps most significantly, real progress requires cross-sector collaboration and systemic thinking—a challenge in industries built on linear, siloed models.
Opportunities
Despite these hurdles, the circular economy opens the door to significant strategic advantages. By reducing dependence on volatile raw materials, companies can enhance supply chain resilience and lower long-term costs. Embracing circular practices also improves brand reputation, builds stakeholder trust, and supports regulatory readiness as sustainability standards tighten.
Perhaps most exciting, circularity enables access to new business models—from product-as-a-service to resource recovery—that align profitability with purpose.
Making circular thinking part of your strategy
The transition to a circular economy is more than an operational shift—it’s a strategic transformation that must be driven by leadership. Executives and decision-makers play a pivotal role in reimagining how value is created, aligning sustainability with performance, and empowering teams to innovate across the organization.
Effective circular leadership calls for a systems mindset—the ability to navigate complexity, rethink linear growth models, and foster alignment across functions and stakeholders. It also requires a cultural shift: encouraging experimentation, managing trade-offs transparently, and embedding sustainability into everyday decision-making.
Some of the key leadership responsibilities include:
- Defining a long-term vision that integrates environmental and business goals;
- Enabling cross-functional collaboration across products, services, and value chains;
- Embedding circular metrics into KPIs, investment frameworks, and governance structures;
- Communicating purpose with clarity to build trust and engagement.
But circularity is not just about leadership—it’s also about strategy. Circular economy represents a fundamental rethinking of how we define value, build resilience, and design systems that operate within planetary boundaries. The 7 pillars offer not only a roadmap for this shift, but also a shared language to coordinate action across sectors, industries, and regions.
As businesses face growing environmental, social, and economic pressures, those that lead with circular thinking will be better positioned to adapt, innovate, and grow with purpose. The shift won’t happen overnight—but it’s no longer optional.
Now is the time to move from understanding to implementation—and from intention to leadership.
