Every leaf that falls from the tree becomes part of a new circle. In non-human ecosystems, everything is reused or repurposed. The natural world is the perfect circular system. Why is the same not true for humankind? Most of the things we posses will ultimately not be used for a long period of time. The current take-make-waste approach is a given fact of the present economy that we have perfected since the industrial revolution. The editors 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. The book brings together thinkers and innovators from academia as well as business who share their idea.
