Every leaf that falls from a tree becomes part of a new circle. In non-human ecosystems, everything is re-used or re-purposed. The natural world is the perfect circular system. Why is the same not true for humankind? Most of the things we possess will ultimately not be used for a long period of time. The current take-make-waste approach is a given fact of our present economy that we have perfected since the industrial revolution. The editors Dr Guenther Dobrauz-Saldapenna and Nicolas Huras believe that we urgently need to change our ways of producing, consuming and living. It is time to seriously consider circular economy as an alternative model. This book brings together thinkers and innovators from academia as well as business who share their ideas. Does it deliver answers to all our challenges? Probably not, but it is a great place to start. The future must be circular and decentralized!
