Cradle to Cradle is a groundbreaking book that challenges the traditional linear model of production and consumption. The authors, William McDonough and Michael Braungart, propose a new approach to design and manufacturing that aims to create products and systems that are not only environmentally sustainable but also beneficial to human health and well-being. This book explores the concept of 'upcycling' and provides examples of companies that have successfully implemented cradle-to-cradle principles in their business practices.
