A transition is defined as ‘The process of changing from one state or condition to another.’ That definition has all too often led us to create the traditional linear economies seen all around the world today. But what if the starting point for transition could be what we think as an end? What if the end was simply the beginning of something new, a new circle of life, the beginning of a new use? What if the materials we believe nowadays to be worthless and ready to be discarded could become new resources for tomorrow? We live in changing times, where hearing about environmental and ecological crises leaves us with no option than to adopt a circular economy. A revolutionary new economy that is not just an environmental solution and economic opportunity, but is a starting point for a new hub of ideas, for creativity, re-creating, re-thinking not only the use of things but all of our habits and attitudes towards the environment.

TEDxParcduCinquantenaire will be hosted by the European Commission in the Breydel building and starts at 18:30. Registration is possible here, but access is on a first-come, first-served basis.
