Circular Coffee Break for Leaders, Innovators, and Practitioners

Michael Hanf

The Circular Coffee Break is a podcast about rethinking how we design, use, and reuse the resources that shape our world. Hosted by Michael Hanf, the podcast dives into the heart of the circular economy with leaders, innovators, and practitioners whose work and lived experiences offer a way into the urgent questions facing businesses, societies, and the planet. How do we move beyond linear take-make-waste models? When do we take responsibility for the systems we’ve created, and how do we redesign them for resilience and regeneration? What happens when circularity shifts from a nice-to-have to a core principle of business and a necessity to stay competitive? Guests come from diverse fields: entrepreneurs and engineers, policymakers and designers, activists and investors. Some conversations explore cutting-edge innovations in material science, AI, or business models, while others delve into the challenges of implementing circularity in industries like fashion, electronics, or construction. What matters is not just what they do, but why it matters: the values, struggles, and breakthroughs that drive them to push boundaries and redefine success. The discussions span the critical questions shaping the future of sustainability. They examine the role of policy and regulation, the intersection of circularity and technology, and the social and economic shifts required to scale circular solutions. They also tackle the tensions between idealism and pragmatism, the trade-offs of transitioning to circular systems, and what it means to lead change in a world resistant to it. Some episodes begin with global challenges, like climate change, resource scarcity, or waste crises. Others start with personal journeys: the story of a founder who turned waste into a business, a designer who reimagined a product’s lifecycle, or a leader who transformed their company’s purpose. They might explore the realities of circular supply chains, the ethics of consumption, or the psychology of behavioural change. At the center of the podcast are questions of agency and impact. How do we turn ideas into action? What does it take to challenge the status quo and build systems that regenerate rather than deplete? How do we balance ambition with feasibility, and urgency with patience? And what does it mean to keep pushing forward when progress is slow, uncertain, or met with resistance? Michael brings over a decade of experience in sustainability, strategy, and business development to these conversations. His approach creates space for guests to share not just their successes, but their doubts, failures, and the hard-won lessons that come from trying to do things differently. The result is honest, thought-provoking discussions that value action over theory, collaboration over competition, and long-term thinking over short-term gains. Whether the conversation is about redesigning products for longevity, navigating the complexities of circular policy, or scaling innovations that challenge the norm, each episode asks: What does it take to make circularity the default? The Circular Coffee Break is for anyone curious about how we can build a future where waste is designed out, resources are kept in use, and nature is regenerated. Conversations that don’t just ask what if but what’s next. Hosted on Acast. See acast.com/privacy for more information.

    #76 - And This Is How It Ends

    After three years and over eighty conversations, The Circular Coffee Break comes to a close. This final solo episode is not a recap but a reflection on why the podcast existed, what was learned, and why it feels right to end it now. Host Michael Hanf shares the origins of the podcast, which began in early 2023 with a simple intention: to slow down the conversation around circularity and sustainability. At the time, much of the public discussion felt fragmented, fast, and overly focused on frameworks and targets. The Circular Coffee Break was created as a space for long-form conversations with people working on circularity in practice, across business, policy, research, and entrepreneurship. The metaphor of a coffee break was intentional—a moment to pause, think out loud, explore trade-offs, and sit with uncertainty rather than presenting circularity as a linear journey from problem to solution. Over the course of these conversations, several patterns became clear: Circularity is rarely a technical problem. The technologies exist, the models are known, and the data is improving. The harder challenges lie in governance, incentives, organizational boundaries, and decision-making.Circularity is a team sport. Progress depends on coordination, trust, and shared direction across many actors, each playing different but critical roles.Progress is uneven but not absent. Meaningful advances are happening, often quietly and in specific contexts, while inertia persists at scale.Context matters. What works in one sector or region does not automatically translate elsewhere. Circularity is not a blueprint but a direction of travel that looks different depending on where you start.Circularity is increasingly strategic. Conversations often touched on resilience, supply risks, competitiveness, and long-term value creation, not just environmental concerns. So why end The Circular Coffee Break now? The simplest answer is that this format has done what it set out to do. It created a body of conversations that captured a specific moment in how circular economy and sustainability were being understood and practiced. Continuing the podcast would either lead to repetition or require a shift that no longer fits its original purpose. Ending deliberately is a form of focus and discipline. This is not a pause, nor a rebranding. It is a clean ending. The archive will remain available, and it is hoped that it continues to be useful as a record of conversations that tried to engage honestly with complexity rather than simplifying it. Michael’s work continues through a separate podcast called Matters of Consequence, which takes a broader lens on the systems change needed in a never-normal world to make companies, institutions, and organizations future-ready. Before closing, Michael expresses his gratitude to the guests who trusted the space enough to think out loud, to the listeners who stayed with the long conversations and nuances, and to everyone who shared episodes, challenged ideas, or carried the conversations forward in their own work. For The Circular Coffee Break, this episode marks a clear and intentional ending.

    #75 - If you want circularity, you have to build it

    What does it take to build a circular business in practice? In this final interview episode of The Circular Coffee Break, we welcome back Jaakko Nauha, CEO of Tracegrow, who was the very first guest on the podcast in early 2023. Almost three years later, Jaakko returns to reflect on Tracegrow’s journey from a battery recycling innovator to a broader clean technology company, and what it really means to scale circular solutions in the real world. Jaakko shares how Tracegrow has evolved from recovering micronutrients like zinc and manganese from used alkaline batteries to processing industrial side streams, such as manganese sludge from zinc smelters. He discusses the company’s expansion into seed treatment, which has shown remarkable results in improving crop resilience and yield, as well as the development of battery-grade manganese sulfate for electric vehicles and industrial energy storage systems. The conversation also explores the challenges of finding product-market fit in agriculture, entering the European battery ecosystem, and scaling under regulatory, logistical, and cost constraints.
