Book excerpt: This original book explores how the principles of circularity, considered a law of nature but neglected within the materialistic orientation of the industrial age, are becoming attractive again in business and society. Investigation reveals enterprises small and large delivering a stimulating message, from changes in entrepreneurial mindsets to the inclusive use of new technologies and a push for innovation. Zucchella and Urban explore the novel concept of circular enterprise, showing how, with their capacity to innovate, these firms are becoming the most powerful actors of a new, sustainable social order. They examine two fundamental questions: why is this revolution occurring now, and how is it being implemented? Focusing on the most innovative practices, they demonstrate the potential of circular enterprise for industry and wider society, making clear that a new world is emerging.
