Circular Economy Podcast

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.

Martin Tomitsch and Steve Baty have written a brilliant book called Designing Tomorrow: strategic design tactics to change your practice, organization and planetary impact, published earlier this year. Martin Tomitsch is a Professor and Head of the Transdisciplinary School at the University of Technology Sydney (UTS). As a design academic and educator, Martin advocates for the transformative power of design to envision speculative futures and drive positive change. He has written lots of academic articles and seven books, including Making Cities Smarter and Design Think Make Break Repeat. Steve Baty was the inaugural CEO of the Australian Design Council, co-founder of Meld Studios and co-founder of UX Australia. He is a Director of the Product Stewardship Centre of Excellence and served two years as the President of the Interaction Design Association. Steve focuses on the integration between strategic design and traditional architectural practice, especially for improving our public spaces, infrastructure and services. You might be noticing interest around supporting responsible innovation in ways that consider all life – human and other-than-human. That might be badged as life-centred, regenerative or post-anthropocentric design, and Martin Tomitsch and Steve Baty say these approaches share an important goal, to ‘reach an operational status where human activity no longer exceeds the planetary limits.’ In Designing Tomorrow, Martin and Steve bring together several design philosophies, to help designers, strategists and policymakers amplify their impact, shift their perspectives and empower them to create lasting positive change inside organizations. We’ll talk about some of the concepts and tools they introduce in the book, why we need to carefully consider who is involved in a system and the broader implications of our design decisions, and ways to change our mindsets – including about stakeholders, our sphere of influence and how to think about strategic decisions.

Loic Le Fouest is a leading expert in Customer Experience (CX) with a strong track record of driving customer-centric transformation across the private, public, and not-for-profit sectors. As the head of the CX practice at Clarasys in the UK, Loic helps organisations design customer experiences that drive loyalty, innovation, and sustainable business growth. Clarasys describes itself as The Experience Consultancy — employee-owned, purpose-driven, and dedicated to helping organisations create better experiences for customers, employees, and the planet. Clarasys recognises that circular economy approaches often require fundamentally different relations between providers and users, and it’s keen to understand more about that. In 2022, Loic launched a partnership between Clarasys and the University of Exeter’s Centre for the Circular Economy to tackle what they saw as one of the biggest challenges in circularity — customer engagement. This collaboration led to a report and toolkit on Creating Customer Experiences in the Circular Economy, providing businesses with practical strategies to make circular models work for their customers. Loic is an experienced transformation consultant with over 10 years of consulting and industry experience, and he combines design thinking with his background in product management, digital transformation, lean 6-sigma and change management. Loic shares insights from Clarasys' collaboration with the Exeter team, which looked at how businesses were dealing with challenges around user adoption and acceptance across the food and beverage and household appliances sectors. The research team looked at the new aspects of roles, behaviour and relationships for consumers/, and Loic explains some of the key findings around that, including ‘consumption work’ and ‘key moments that matter’ for customers. The study also found that firms were struggling to launch and scale successful circular business models, and Loic talks about two kinds of approaches to that - ‘inside out’ versus ‘outside in’.

We hear insights from Anette Timmer of DESSO by Tarkett, a leading carpet brand that was an early adopter of circular economy principles. Anette Timmer began her journey with DESSO almost 18 years ago, and has played a central role in the business’ transition to a circular economy model. Anette helps to bridge the gap between the vision and execution of circular transformation, using marketing and communications to educate audiences about circularity; develop stakeholder trust and transparency; inspire behaviour change among customers; and build advocacy and momentum across the wider industry. Anette is a strong advocate for cross-industry collaboration, where businesses share experiences, and work together to create systems to circulate products and materials. DESSO is now part of Tarkett, and has a long-held belief in designing with people and planet in mind, and over a decade ago, it made a bold commitment to place circularity at the core of its ambitions.

Moving towards a closed-loop system has involved a total change of mindset within the business. DESSO calls its commitment the Beauty of Circularity, and it drives the business to do more with less at every stage. - Annette unpacks the three pillars of Desso's beauty of circularity strategy: designing products to live multiple lives; developing innovative materials that are made to be remade; and building systems to return flooring at end of life to complete the circular journey. And sometimes, synchronicity steps in to lend a hand!
