I recently completed the Delftx CircularX: Circular Economy – An Introduction course, and I wanted to share what I’ve learned.
The course introduced me to the concept of the Circular Economy (CE), which is all about shifting from the traditional linear model of “take, make, waste” to a system where resources are reused, refurbished, remanufactured, and recycled. Instead of throwing things away after use, the idea is to keep materials in use for as long as possible. This can reduce waste, lower the demand for raw materials, and decrease environmental impact.
A key takeaway for me was the idea that the economy doesn’t need to be built around constant growth in the traditional sense. By focusing on sustainability and extending the life cycle of products, we can create a more resilient and resource-efficient system. I also learned how circularity works on both a product level (like in recycling and design) and a larger scale (where systems and business models adapt to keep things in use).
The course highlighted several principles such as designing for longevity, reusing products, and using renewable energy sources. There were also examples of companies and projects that are already working in a circular way, proving that it’s not just a concept but something that can be implemented now.
Overall, this course has definitely broadened my perspective on sustainability and has motivated me to think more about how we, as consumers and creators, can contribute to building a circular economy. It’s clear that moving towards a circular model isn’t just good for the environment, but it also makes business sense by reducing costs and creating new opportunities for innovation.
If you’re interested in sustainability and want to dive deeper into the circular economy, I highly recommend this course!
