The concept of the circular economy is everywhere, but it is still often misunderstood. Efforts to transition to this model, including through the principles of ecodesign, are therefore often limited to low-hanging fruit or even examples of greenwashing. Karine Van Doorsselaer, Senior Lecturer in Materials Science and Ecodesign at the University of Antwerp, aims to change this with her lecture at Advanced Engineering on Thursday, May 22.
Are cardboard cups better for the environment than plastic cups? Can circularity and environmental impact really be expressed in numbers? You might be surprised, but the answer to these questions is no. “These and many more misconceptions about ecodesign and the circular economy need to be debunked,” argues Karine.
Ecological Materials Donât Exist
Ecodesign is about designing products with the smallest possible environmental impact. But how do you achieve that? And what factors should you consider? Karine wants to broaden the perspective of engineers and designers.
One way she does this is by critically examining the use of so-called ecological materials. “Because they donât actually existâitâs all about using materials in an environmentally responsible way.” Another common misconception she will debunk is that the circular economy is merely about recycling materials. Before a product is recycled, it should be used for as long as possible, repaired, reused, and stripped down so that its components can be repurposed.
Lifecycle thinking
“Ecodesign is about balancing various factors, such as environmental impact (throughout every stage of a productâs life!), technical aspects, cost, lifespan, usability, repairability, reusability, and, finally, recyclability. That is âlifecycle thinkingâ.”
The use of biomaterials should also be approached critically. “For example, if we focus on using bamboo or hemp but, in doing so, significantly reduce a productâs lifespan or usability, it will end up in the waste stream much sooner. Thatâs not ecological at all. The thoughtless use of biomaterials is a pitfall that many designers fall into!”
Through her lecture, Karine aims to provide a critical lens that professionals can apply in their daily work and life. “I hope that everyone attending the lecture will learn to think more long-term and realize that enabling a circular economy is a shared responsibility.”
“80% of a productâs environmental impact is determined during the design phase. Designers and engineers, therefore, have a huge responsibility. However, everyoneâfrom policymakers to consumersâplays a role in this transition to a sustainable circular economy,” Karine concludes.
