Walter Stahel (WS): I trained as an architect at the Swiss Federal Institute of Technology in Zurich, and worked in London and Switzerland before I joined the Battelle research centre in Geneva. Here, he discusses some of the issues, developments and ways forward.Ĭircular (C): What are the origins of your ideas about the circular economy? ![]() Stahel has been invited to be a guest speaker at CIWM’s flagship Festival of Circular Economy virtual event on 20-21 April.

Nature works in a circular way, because every waste becomes food for something else. His report The Product-Life Factor, which was published in 1982, first set out his ideas. In the 1970s, Stahel developed his theories proposing that industry adopts the reuse and service-life extension of goods as a strategy of waste prevention, regional job creation and resource efficiency in order to decouple wealth from resource consumption. With his initial research and writing on closed economy loops beginning more than four decades ago, Walter Stahel is widely recognised as one of the key pioneers of the ideas and theories that have developed into the concept of the ‘circular economy’.Ī trained architect living in his native Switzerland, Stahel is co-founder and director of the Product-Life Institute in Geneva, a consultancy that works to develop sustainable strategies and policies. ![]() ![]() Given: Length of conical pendulum = l = 5.Ahead of speaking at CIWM’s Festival of Circular Economy, Dr Walter Stahel, one of the key contributors to the ideas and theories that helped formulate the concept of the circular economy, discusses the past, present and path to a sustainable future.
