Influential Figures and Organizations in Circular Economy

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.

International speaker, author and strategic advisor, Catherine Weetman helps people discover why circular, regenerative and fair solutions are better for people, planet – and prosperity.

Catherine’s award-winning book: A Circular Economy Handbook: How to Build a More Resilient, Competitive and Sustainable Business includes lots of practical examples and tips on getting started.

Playlist: getting started with the circular economy…

Want to know more about the what the circular economy really is, and how it can help your business?  Here’s a playlist to help you get to grips with the concept, how it creates value, and the common myths (spoiler alert – it’s much more than recycling!)

• #1 What is the circular economy: A quick intro to explain what the circular economy is and why it’s important. We explore how it helps create better products and services, and at the same time helps to make a better world. I break it down into my 5 circular economy components, helping you think about each part of your business.
• #2 The linear economy and your risk checklist: We dig a bit deeper into the way we do business now, the linear economy, and why that’s creating problems for business, society and our living planet. Also, we’ll look at the risks that emerge from those big-picture issues, and how they might affect your organisation.
• #90 Does circular mean it’s sustainable? Catherine Weetman is worried that companies are using circular economy solutions to grow their business (and their footprints).
• #101 Circular is better for people, planet and profit! How three simple strategies can help you get started with circular and regenerative solutions that are better for people, planet and profit.
• #120 Priorities are changing: people find life is better when we care for and share things – circular economy strategies make that better for business, too.

And here’s Catherine’s guide: What is the circular economy? 

Want to dig deeper?

Why not buy Catherine’s award-winning book, A Circular Economy Handbook: How to Build a More Resilient, Competitive and Sustainable Business. This comprehensive guide uses a bottom-up, practical approach, and includes hundreds of real examples from around the world, to help you really ‘get’ the circular economy.  Even better, you’ll be inspired with ideas to make your own business more competitive, resilient and sustainable.
