I recently followed the online course “DelftX: Circular Economy: An Introduction” from TU Delft, and it turned out to be much more transformative than I expected.

I started this course already passionate about sustainability and pretty familiar with the basic ideas of the circular economy. But I quickly realized the system is much deeper and more sophisticated than I had imagined. It didn’t just reinforce what I knew—it revealed the real mechanics behind making circularity actually work. These are the ideas that truly expanded my perspective:

1. The Business Model Is the Real Engine
I already understood that circular design matters, but the course showed me that business model innovation is where the real transformation happens. The examples of Caterpillar and MUD Jeans are basically case studies in how to do this right. By shifting from selling products to selling performance, they link their financial success directly to environmental stewardship. Their achievements aren’t niche—they’re proof that the most sustainable option can also be the most competitive.

2. “Value Loops” Have a Meaningful Hierarchy
I knew recycling was important, but the framework of value loops and the “Inertia Principle” gave me a completely new lens. The hierarchy—Repair > Remanufacture > Recycle—isn’t just a nice slogan; it’s an economic strategy to preserve the labour, energy, and complexity already embedded in a product. Seeing how Cat Reman rebuilds a sophisticated engine component to a “like-new” condition, instead of simply melting it down, really showed what it means to keep value circulating at its highest possible level.

3. Design for Disassembly Is Where Circularity Actually Begins
The Fairphone example really brought this home for me. It’s one thing to know that products should be repairable—it’s another to see a company build an entire business around modularity and simple, screwdriver-only repair. I personally support this brand and can say first-hand that it’s genuinely worth it. Fairphone shows exactly what’s possible when repairability isn’t an afterthought but the starting point of the design process. It also highlights the huge gap between a world of disposable, glued-shut devices and one where we have real control over the lifespan of our products.

4. The “Urban Mine” Is the Resource Frontier We’ve Been Overlooking
Ester van der Voet’s work completely reframed how I see cities. Instead of thinking of them as resource consumers, I now see them as our future mines. The aluminium in buildings and the copper in our infrastructure aren’t inevitable waste—they’re some of the richest and most accessible ore bodies we’ll ever have. This shift—from scarcity to smart resource management—changes the whole narrative.

5. Biomimicry Shows What Elegant Efficiency Looks Like
Finally, the course made biomimicry feel much more concrete. The example of Interface designing carpet tiles inspired by the random patterns of a forest floor was a real “wow” moment. It’s such a simple idea, but it eliminates installation waste entirely. It shows how designing like nature isn’t just poetic—it creates systems that are efficient, effective, and fundamentally regenerative.

In the end, this course helped me connect everything together. The circular economy isn’t a set of isolated concepts—it’s a coherent, intelligent system where design, business models, and resource thinking all reinforce each other. It’s practical, it’s viable, and honestly, it’s one of the smartest pathways we have for the future. I’m leaving the course even more convinced of its potential—and its necessity.

I’m sharing the link here because I genuinely recommend it to anyone who wants to understand these topics more deeply:
