From the archives – episode 119 with Ken Webster: why we need to talk about the circular ECONOMY!

To close out 2025, I’d like to revisit a critical aspect that’s being ignored – the economy itself. Ken Webster is a leading thinker in the circular economy field, and one of his many roles is with Earth4All, where he has been exploring the benefits of a Universal Basic Dividend. Ken and Catherine discussed this, and more aspects of circularity at an economic level back in 2023, and it’s highly relevant today, as the challenges we face loom larger.

172 (Part 2) Tom Llewellyn of Shareable: how sharing and cooperative projects help us thrive

This is the 2nd part of my conversation with Tom Llewellyn of Shareable, an organization that collaborates with others to imagine, resource, network, and scale cooperative projects.
• We hear about Shareable’s How-To Guides, which cover a vast range of topics from how to reduce food waste to starting mutual aid funds, and Tom explains how sharing initiatives are starting to be included in city and local government policies.
• And Tom offers his top tips for how we can get started with sharing and other initiatives, to improve our resilience and build stronger communities.
If you didn’t catch the first episode, head back to that if you’d like to hear why Shareable has pivoted from storytelling to focus on supporting groups to replicate successful sharing solutions, what Tom sees as the key challenges around sharing, and the importance of storytelling – including the misleading narratives used by most of the media, and how these undermine our resilience.

172 Tom Llewellyn of Shareable: how sharing and cooperative projects help us thrive

We discuss the importance of sharing and its many benefits with Tom Llewellyn, the Executive Director of Shareable, which collaborates with others to imagine, resource, network, and scale cooperative projects.
Tom helps communities develop Libraries of Things (LoTs) and other forms of low-cost, environmentally friendly social infrastructure that help people meet their material needs. Tom’s current work includes expanding these sharing initiatives into housing developments, universities, and post-disaster recovery areas.
He also serves as executive producer and host of the award-winning documentary film and podcast series The Response, producer of the Cities@Tufts Podcast, and communications lead for the Rural Power Coalition.
Tom has co-founded several community- and sharing-based initiatives, including: A PLACE for Sustainable Living, Asheville Tool Library, REAL Cooperative (Regenerative Education, Action & Leadership), and the worker collective Critter Cafe.
Shareable wants to see a just, connected, and joyful world where sharing is daily practice and communities flourish. Its current focus is on sharing hubs & infrastructure, Mutual Aid projects, and supporting and strengthening democratic, community-controlled cooperative businesses and organizations.
We covered a lot, and so the conversation is split into two episodes. In Part 1, we hear why Shareable has pivoted from storytelling to engagement and support for groups to replicate successful sharing solutions.
We discuss some of the key challenges and barriers to sharing, and what we can gain from sharing and other forms of mutual support
We talk about a few different types of sharing initiatives, including community infrastructure projects.
Tom explains the importance of storytelling, particularly in the context of disasters, and how the media often uses narratives that undermine our natural resilience and willingness to support each other.
In Part 2 (available now), we cover the How To Guides, which cover a vast range of topics from how to reduce food waste to starting mutual aid funds, and Tom’s tips on how to get things started. You can hear my takeaways at the end of each section.

171 Dr. Patrick Schröder: circular economy policymaking – progress and barriers

Dr. Patrick Schröder, a senior research fellow at Chatham House, assesses the progress and barriers for circular economy policymaking. Patrick Schröder specializes in the circular economy, climate change, resource governance, and the Sustainable Development Goals (SDGs). His work brings together science, policy, and media to help further evidence-based policies, communicate complex sustainability issues, and promote equitable governance solutions at the multilateral level.
Patrick is currently the Coordinating Lead Author for one of the three working groups for the IPCC Assessment Report 7, reporting on Mitigation of Climate Change, and he is also the Coordinating Lead Author for the UN Global Environment Outlook 7. Patrick holds a PhD in Environmental Studies, and is now studying part-time for a second PhD in circular and regenerative design with the Centre for Sustainable Design.
In 2024, UNIDO and Chatham House published a ground-breaking global stocktake of 75 national circular economy roadmaps featuring more than 2,800 policy actions. The first roadmap, from Japan, was published in 1999, and since 2016, as governments strive to accelerate their circular transitions, over 70 countries have published national circular economy roadmaps and strategies.
The review aims to ‘bridge knowledge gaps and shed light on critical aspects of these publications’, and the authors point to a ‘significant lack of focus on the need to ensure a just and inclusive’ transition, warning that a ‘lack of recognition of the need to work collaboratively with the global community’ risks derailing a global just transition.
Patrick tells us how he currently sees the global state of play for circular economy policies and roadmaps, where progress is happening and from a policymaking perspective, what is holding it back.
The team at Chatham House have created a micro-site – circulareconomy.earth – and Patrick tells us more about that, and how we can use it.

episode 169 reuse of architectural components

169 Bailey Bestul: imaginative reuse of architectural components to create exciting and inspiring buildings

Bailey Bestul explains how imaginative reuse of architectural components can create exciting, unique and inspiring buildings. Bailey is a registered architect, researcher and author based in New York City. His book, Reuse of Architectural Components, published by Routledge, was inspired by Bailey’s extensive research throughout Europe after he was awarded a Fulbright grant by the Netherland-America Foundation.
We discuss how architects, constructors and building owners are getting on board with circularity and reuse, and what might be getting in the way of ambitious circular approaches, and ask what architects, building owners and planners can do to help raise awareness of the benefits of reuse.

164 Louis De Jaeger: our futures depend on healthy soils

Healthy soils provide the foundation for life on our planet, and yet most agriculture degrades soil. Nurturing soil should be at the top of all our priority lists, and Louis De Jaeger—author of the new book ‘SOS: Save Our Soils, How regenerative farming can save your health and the planet’ — helps us understand why it’s so important, and what we can do about it.
Louis says his life mission is to regenerate 550 million hectares of land, to cool down the planet, save biodiversity, end hunger, and create world peace.
For the past twelve years, Louis De Jaeger has travelled extensively through North America, all the way to Panama, through Europe, South America and Africa. Along the way, he’s visited farms and interviewed a wide range of people, from pioneering regenerative farmers to corporate lobbyists, and explored one central question: How can we feed the world without destroying it?
Louis says, “To be honest, it really took a while to find clear answers on what the best way is to shape the future of food.” He is grateful for insights he couldn’t have dreamed of, and he shares them in SOS: Save Our Soils. Louis says the book is a manifesto, a global quest, and an invitation for all of us to step into the most critical conversation of our time: the future of food.”
Healthy soils are probably the most important element in our system – they are essential for nurturing us, nurturing the living systems we depend on, for drawing down carbon, for providing clean air and water, and much more. Every one of us, and every business, depends on soil – Louis De Jaeger explains why this is an SOS, and what we can do about it.

163 Patrik Frisk of Reju: regenerating polyester textiles

We dig into the complexities of textile recycling with Patrik Frisk, who is working to create a circular economy for textile-to-textile polyester regeneration. Patrik is the CEO of Reju, a recent startup enabling polyester to be recycled at speed and scale.
Patrik has over thirty years’ experience of working in the apparel and footwear industries for globally recognised brands, joining Reju after 5 years as CEO at Under Armour. Patrik has extensive experience in textiles, including senior leadership roles at VF Corporation (the owner of outdoor brands including The North Face, Timberland, JanSport), the Aldo Group and W.L Gore & Associates, the makers of Gore-Tex.

Reju itself is a materials regeneration company focused on creating solutions for regenerating polyester textiles and PET waste. Reju is owned by Technip Energies and, as we’ll hear, it is using technology that originated from research by IBM.

Patrik explains the size of the problem, and the many complexities of trying to effectively recycle end-of-life clothing and textiles. We hear how brands and policymakers are responding to the growing issues caused by fast-fashion, including some legislation changes that are encouraging organizations to think differently, and to consider investing in proper recycling (not downcycling) technologies.

We discuss the challenges around logistics, infrastructure, how to deal with mixed fibres, and why being able to recycle mixed textiles into a clean, high quality polyester output is such a groundbreaking innovation.
