Circular Economy Podcast

One of recurring themes in the new edition of A Circular Economy Handbook (to be published in November 2025) is the importance of systems thinking and systems design. I’ve been reading Seth Godin’s book, This is Strategy, and he says successful strategies depend on two things: being conscious of the change we seek to make and the systems that can amplify or impede our progress. In other words, we must make sure we understand the different systems affecting the things we want to change. There can be multiple systems, many of which we have little control over. It’s also important to find the ‘leverage points’ – those places in complex systems where, as Donella Meadows said, ‘a small shift in one thing can produce big changes in everything.’ Pretty much every conversation in the last series gave me food for thought and insights for the book, and in this episode, I’d like to pick up on some of those. First, we’ll recap on the systems thinking tools and approaches in Martin Tomitsch and Steve Baty’s new book, Designing Tomorrow, and think about the impact of strategies and systems - who we affect, and what kind of impacts we’re responsible for. Then we’ll look more closely at one of the key differences between conventional and circular business models - the role of the customer, and the need for them to be active, rather than passive participants. Finally, we’ll unpick another recurring theme from the book - system value – a term used by the Future Fit Foundation for solutions where businesses address societal needs in a holistic way, while not hindering progress towards a flourishing future. The last series covers episodes 151 to 159: 151 Clarissa Morawski of Reloop Platform: practical policies for circular packaging 152 Markus Terho: The Lifestyle Test 153 Anette Timmer of DESSO: the beauty of circularity 154 Loic Le Fouest of Clarasys: creating circular customer experiences 155 Martin Tomitsch and Steve Baty: Life-centred design 156 Marcus Feldthus: the Post-Growth Guide for businesses 157 Liz Bui of Yulex: safer, sustainable materials 158 Steve Wilson of Compostify: bioplastics that enrich the planet 159 Kyle Wiens of iFixit: the rewards of repairability

Kyle Wiens is the co-founder of iFixit, the international repair community known for open-source repair manuals and product teardown. Kyle is also one of my circular economy heroes! Since it started back in 2003, iFixit has empowered hundreds of millions of people to repair their broken stuff. Kyle led the international coalition that legalized Right to Repair, has testified before the US Congress and the International Trade Commission, and he is helping to develop global environmental standards. Kyle brings us up to speed on how iFixit has evolved over the last two decades, in its reach, offer and engagement. We talk about why we’ve ended up with so many products that are not designed to last and are hard – or impossible to repair, and why things are changing for the better. Kyle explains the importance of the Right to Repair legislation that’s being rolled out, how brands that don’t get on board risk losing out, and explains why we need much more information about product durability and repairability. We discuss some of the ways that brands can improve the design and durability of their products, and how iFixit can help them with that, and he offers a simple suggestion to help us all make better buying choices.

Compostify makes truly home-compostable plant pots and other bioplastic solutions designed to nourish the earth. Its products naturally break down without leaving harmful residues, and Compostify says this packaging enriches the planet, rather than polluting it. Steve Wilson is the Co-founder and CEO of Compostify, with a background in scaling technology businesses. Steve is applying his expertise in innovation, partnerships, and market expansion to make compostable packaging a mainstream reality. We talk about where the idea came from, and how they partnered with researchers to develop solutions, with a very challenging design brief that would support scaling this out around the world. We talk about the criteria for the biomaterials and Steve explains the design features of the pots, meaning the Compostify solution enables ‘retailers, growers, nurseries, distributors, and manufacturers to transition to home compostable plant pots without sacrificing performance or ease of use.’ Steve also tells us about the feedback from gardeners, and the surprising benefits that emerged when commercial gardeners began using the pots.

Liz Bui takes us behind the scenes at Yulex, a material science company that’s replacing extremely useful, but problematic petroleum-based products with natural rubber alternatives. Liz Bui is Chief Executive Officer at YULEX, based in the USA. She began her career in the biotechnology and pharmaceutical industry where she spent 20 years in senior roles. On top of managing all operational and business matters at YULEX, Liz is an intellectual property and transactional lawyer, a PhD scientist and also an adjunct professor at the University of San Diego School of Law. Originally from Vietnam, at the age of six Liz escaped on the day Saigon (now Ho Chi Minh City) fell to the North Vietnamese forces. She and her siblings, without their parents, were war refugees aboard a fishing boat until they were rescued by a US aircraft carrier. Like other Vietnamese refugees from that period, she was granted permanent residency and a new life in the U.S. We’ll hear about the origins and mission of Yulex and its long-term collaboration with Patagonia to develop natural rubber foam for wetsuits, replacing neoprene, a petroleum-based material. Liz explains some of the key principles underpinning Yulex’s approach to innovation, and how these are fundamental to helping it scale out and create benefits right across its value network. Liz talks us through some of the environmental and health issues associated with neoprene, and explains how Yulex is making it easier for suppliers to use natural rubber instead. She tells us about Yulex’s latest material innovation, Yulastic filaments - a sustainable alternative to petroleum-based elastane, aka spandex. And we hear how Yulex's Equitable AG program supports rubber smallholders in Southeast Asia, distributing 50% of the profits back to them.

We zoom out to the economy part of the circular economy, to talk about the Post Growth concept, with Marcus Feldthus. Together with Oscar Haumann, Marcus founded the Post Growth Guide back in 2023, as a learning space for people who want to understand the social and planetary boundaries so as to make real sustainability strategies, avoiding greenwashing, going beyond compliance, and leading the way forward for their business and wider industry. The platform has a growing membership community and offers explainers, case studies, online courses, books, and public talks. Marcus Feldthus is an entrepreneur from Denmark with a Master's Degree in Business from Copenhagen Business School. Marcus, with Oscar Haumann also started a consultancy called Abel, back in 2015. Marcus will explain the concept of Post Growth, its historical roots and what its aiming to achieve, and we talk about how the circular economy fits into a Post Growth system. We discuss how Post Growth is gaining traction and how it aligns with some of the other approaches to progressive economic, including degrowth and regenerative economics. Marcus tells us more about the Post Growth Guide and course, about his new book, “The Economies of Small Scale”, coming out soon, and why conversation starters are a great tool to help us all think about this from practical, business perspectives.
