Circular Snapshots | COP30 and progress in the circular economy

Recorded live at Climate Week New York, in this episode we ask ‘why should retailers embrace the circular economy?’

The global food system is responsible for a third of greenhouse gas emissions, and is vulnerable to supply chain shocks. 

Our guests discuss why circularity must be easier, more convenient, and more irresistible than the linear option, and why retailers and brands need to invest in shared solutions to scale a circular economy for food.

Joining the Ellen MacArthur Foundation’s Executive Lead for Retail, Reniera O’Donnell, are:

 • Nate Hurst, Chief Sustainability Officer at Visa
 • Burgess Davis, Senior Vice President and Chief Sustainability Officer for North America at PepsiCo
 • Scot Case, Vice President of Sustainability for the National Retail Federation

What's tech got to do with it? | Conversations from Climate Week New York

This is the fourth and final part of our mini series on the Ellen MacArthur Foundation’s new report: How not to fail: Avoiding 10 common pitfalls when scaling circular business models.

In this episode, the report’s lead researchers, Maddy Oliver and Ella Hedley, explain how success at scale demands more than a strong model – what really matters is who is empowered to deliver it and how well are they aligned.

Why do circular business models fail to scale? Going it alone

Circular business models can drive new revenue streams, build brand strength, customer loyalty, and market traction, while also unlocking value through resource efficiency, cost savings, and reduced risk to supply chain volatility. But there is often too much focus on short-term gains in revenue or sustainability and waste reduction metrics, while overlooking their full business value. 

In the third part of our mini series on the Ellen MacArthur Foundation’s new report: How not to fail: Avoiding 10 common pitfalls when scaling circular business models, we hear how, when circular business models are pitched primarily around sustainability, internal commitment is lower.

Pippa is joined by the report’s lead researchers, Maddy Oliver and Ella Hedley, to explore why circular business models rarely scale without a strong, broad financial case. 

They also talk about the need for more commercial collaboration. Find out more by listening to episode 196, HolyGrail: see it, sort it, scale it, to learn how one business-led partnership came together to align on the technology and achieve scale.

Why do circular business models fail to scale? Relying on a narrow business case

Circular business models often fail when they’re designed without factoring how the business works, what the customers want, and what the product requires. 

These need to be considered together, not in isolation, to ensure that delivery, adoption, and revenue generation are possible at scale.

Thinking about fit might feel obvious, but in this episode, we hear how many businesses often overlook these elements.

In the second part of our mini series exploring the Ellen MacArthur Foundation’s new report: How not to fail: Avoiding 10 common pitfalls when scaling circular business models, Pippa is joined by Maddy Oliver and Ella Hedley, who led the research on the paper.

You’ll hear about three common pitfalls around strategic misalignment, and how to avoid them.

Why do circular business models fail to scale? Strategic misalignment

What makes circular business models fail to scale? In this new four-part series, we’ll be exploring the common mistakes businesses make on their journey towards circularity.

Based on the Ellen MacArthur Foundation’s new report: How not to fail: Avoiding 10 common pitfalls when scaling circular business models, Pippa is joined by Maddy Oliver and Ella Hedley, who led the research on the paper.

You’ll hear about the experiences of pioneering companies, and learn about the practical steps that businesses can use to avoid common pitfalls and enable circular business models to reach transformative scale.

In this episode, we explore:

 • What opportunities circular businesses can offer
 • How the report came about, and why it focuses on failure
 • Why lacking a plan of scale from the outset is the first pitfall and some solutions to consider
 • What happens when circular business models don’t align with the existing strategy of the business, and how to avoid this

Why do circular business models fail to scale? Don’t think too small

Have the current political and economic shocks actually created enormous opportunities for change?

Can businesses currently working on transforming themselves, work together on driving an entire market transformation?

And what role can the rest of us play in resetting the system and helping to shape that change?

In this episode, Jonquil Hackenberg, CEO of the Ellen MacArthur Foundation, and Lindsay Hooper from the Cambridge Institute for Sustainability Leadership discuss how catalysing market interventions and designing out competitive disadvantages can work to reshape our system.

We know that complete market transformation is possible, we have already seen renewable energy progress, but no single business or group can do this alone. 

In this episode hear how:

 • Market transformation differs from the incremental changes we’ve seen so far

 • 
 • A system change will require building pre-competitive coalitions who all have a vested interest in change and supporting market making value chains

 • 
 • By harnessing the power of both business and the private sector, we can work together for real transformation

Stop minding your own business

Scaling the circular economy requires more companies to launch circular products and services, but many competitors transitioning towards the circular economy face similar barriers to scale.

One way to address this is commercial collaboration, where businesses work together on issues that are not tied to their competitive advantage.

In this episode, we’ll hear from Sarah Dodge and Mark Buckley from the Ellen MacArthur Foundation about how this can help to scale a circular economy.

We’ll also explore how one initiative has helped address a bottleneck in post-consumer recycling. 

Hear how companies from the Ellen MacArthur Foundation's Plastics Mission worked together to develop a unified vision and enable high-quality plastic waste sorting at scale with HolyGrail 1.0. This evolved into HolyGrail 2.0, where joint investment in R&D was crucial in helping it get from concept to market in just a few years.

To discuss the project, Sander Defruyt, Lead of Strategy & Thought Leadership for the Plastics Mission, is joined by Gian De Belder, Technical Director of Packaging and Sustainability at Procter & Gamble, and Margherita Trombetti, Project Manager at the European Brands Association (AIM).

Watch or listen to the full episode to learn how:

 • Cross-value chain collaboration was essential to align on the technology and achieve scale
 • Growing interest allowed participation to grow from 31 companies in HolyGrail 1.0 to 176 in 2.0 
 • The European Brands Association (AIM) facilitated the governance, confidentiality, and communications of 2.0

Learn more about this business-led partnership, which was funded through member contributions and philanthropic funding from the Alliance to End Plastic Waste and the City of Copenhagen.

HolyGrail: see it, sort it, scale it

Imagine if one day we could grow our buildings! In this episode, hear how one company is already developing radical biotechnologies to innovate the construction industry and beyond.

Dr Ehab Sayed, Founder and Chief Evolution Officer at BIOHM, discusses how biotechnologies such as mycelium - the root structure of fungi - help to accelerate the transition to a circular economy, his personal journey to this space, and how one day we might be able to grow our own buildings.

This conversation also appears in episode 61 of The Circular Economy Show. Watch it here.
