Circular Economy in practice: 5 Business lessons from sustainability leaders

Whether your priority is efficiency, profitability, or both, a circular business model is often lauded as best practice to cut costs and improve resource efficiency. Closing the production loop is the simple solution, right? Redesign the product, improve recycling, eliminate (or perhaps incorporate) waste. In practice, it’s rarely that neat. Circularity cuts across commercial models, supply chains, assurance, reporting, and customer expectations, and it forces organisations to make trade-offs in the open.

What is a circular economy?  
Unlike the traditional linear model of “take, make, dispose”, the circular economy seeks to optimise resource efficiency by keeping products and materials in use for as long as possible through a combination of reuse, repair, remanufacturing, and recycling.

Key Takeaways

Recently we hosted a breakfast roundtable with sustainability leaders from industries spanning manufacturing, construction, retail, CPG, and building materials. The conversation was candid and practical – focusing on what’s hard as well as what’s starting to work:

• Circular economy initiatives need both commercial logic and strategic intent
• Incentives and accountability must align across functions
• Simpler metrics outperform complex reporting frameworks
• Verification and assurance are critical as circular business models scale
• Leadership must define risk appetite to enable faster decision-making

Below are five big themes that kept surfacing, and a few tactics that can help move things forward.

1. The business case is necessary, but it’s rarely the whole story

Circularity requires a clear business case and commercial logic, but early initiatives often start small and take time to deliver results.  In some sectors, the push comes from clients (for example, contractual requirements, upfront carbon targets, and “circularity statements”), while in others it’s an internal attempt to build momentum and create the right environment for investment confidence, through which circularity can scale.

Our conversation highlighted two methods to gain this confidence:

• Anchor the business case in risk and resilience, rather than ‘doing the right thing’. For example, supply security, regulatory exposure, reputational risk.
• Treat pilots as learning investments with clear knowledge outcomes, not just ROI promises.

2. Circularity needs a shift in incentives and accountability, not just ambition

Circularity often stalls when it sits ‘near’ the business rather than being embedded within it.  People described the friction of trying to deliver circular outcomes when finance, procurement, logistics, and commercial teams aren’t measured on the same objectives. It isn’t enough for leadership to be broadly supportive – the infrastructure needs to serve the goal.
We also heard how powerful it can be when incentives have teeth. Sustainability-linked KPIs, scorecards, and in some cases, remuneration linkages can move circularity from optional to operational. 

Tips included:

• Introduce a small number of shared KPIs that the organisation can genuinely rally around and that leadership understands.
• Make accountability explicit – name who owns delivery, not just strategy.

3. Simplicity is key; too many metrics and definitions slow progress

Across sectors, organisations face a common challenge: too much to measure and too little to act on. Carbon, nature, circularity, and resilience each have their own client KPIs, methodologies and reporting expectations. In construction, even agreeing definitions (for example, what can be counted as low-carbon or circular materials in practice) can take months and still leave teams unsure how to communicate it clearly.

The group kept returning to the same practical insight: simplicity wins. A slightly imperfect measure that drives action will outperform a perfect measure that paralyses. Participants suggested:

• Start with a minimum viable measurement set that teams can use month to month, then improve it over time.
• Translate technical detail into boardroom language – e.g. ‘Here’s the target, here’s the forecast, here are the actions.’

4. Proof, performance and verification: building confidence in circular outcomes

Building confidence in circular inputs and outcomes remains a major challenge, particularly where the cost of failure is high.  Whether it’s infrastructure assets with long lifetimes or premium products where brand trust is paramount, organisations need practical ways to prove performance, authenticity and consistency.

Add to this that, as circularity scales, waste increasingly becomes a raw material, which raises the bar on verification and controls. Around the table we were hearing about tighter specifications, contamination issues, and even fraud risk as materials start trading at higher value. 

How can we combat this?

• Simplicity again – make the assurance story easy for others to trust and repeat. Be clear on what evidence exists and what still needs proving, and aim for approaches that can be applied consistently across more than one pilot.

5. Align on risk appetite at the top so teams can move faster with confidence

Circularity is increasingly tied to risk management and governance, from greenwashing and claims exposure to assurance and internal sign-off.  Several people described the shift from ‘doing the right thing’ to risk mitigation at senior level. 

They suggested:

• Have a deliberate conversation with the board/senior team on risk appetite so teams aren’t guessing where to be bold, where to be conservative, and what thresholds of evidence are required.
• Translate that into a simple playbook so teams can make decisions without escalating everything.

Final Thoughts

Circular business models presents both a challenge and a terrific opportunity – but too often, businesses find themselves caught between the pressure to act and the paralysis of not knowing where to start. Or, perhaps more problematically, how to prove it's working. These are challenges of complexity – something that a little perspective can often solve.  Ultimately, implementing circular economy principles is less about perfect solutions and more about aligning commercial, operational, and risk decisions across the organisation.

Cognosis works with business leaders to help provide that perspective – diagnosing where circularity can create the most commercial value, and building the strategies and operating models that make it stick.  Our Circular Value Chain Diagnostic is one practical starting point: a structured way to identify where circular thinking can reduce risk, unlock growth, and build resilience across your value chain.  

Frequently asked questions

What is driving businesses toward the circular economy?  Businesses are being pushed toward circular economy models by both regulation and market demand. New policies, reporting requirements, investor expectations, customer preferences, and supply chain pressures are making circularity increasingly commercially important, not just environmentally desirable.

Why are circular business models becoming strategically important?   Circular business models can improve resilience, reduce resource dependency, unlock new revenue streams, and strengthen customer relationships. Many organisations now see circularity as a long-term competitive advantage rather than a standalone sustainability initiative.

What prevents companies from implementing circularity successfully?  Many organisations struggle because their operating models, incentives, supply chains, and governance structures were designed for linear growth. Circularity often fails when it remains isolated within sustainability teams instead of being embedded into commercial and operational decision-making.
