In this episode of Design Perspectives, host Martin Pauli speaks with Conny Bakker, Professor of Circular Product Design at TU Delft. For more than three decades, she has been working on how products can be designed so that materials, components and entire products stay in circulation for as long as possible.
The conversation explores the practical challenges of circular design — from repair and reuse to ownership models, and the question of why circularity always requires a rethink of business models and supply chains. Conny Bakker also reflects on how design education is changing and why sufficiency may become a more important part of the sustainability debate in the future.
Products do not disappear after useConny Bakker describes how, during her design education, products effectively “disappeared from designers’ consciousness” once they had been used. Circular design starts precisely at this point: designing products so that they can be repaired, reused and kept in circulation over the long term.
Circularity is more complex than many companies realiseRecycled materials alone do not make a product circular. The conversation highlights why circularity also involves business models, supply chains, take-back systems and user behaviour — and why many companies struggle when they try to change everything at once.
Why the question of “enough” is becoming more importantTowards the end of the episode, Conny Bakker raises a more difficult question: is circularity alone enough? Alongside recycling and efficiency, sufficiency may increasingly come into focus — in other words, the question of how much consumption and innovation are actually necessary.
