"Cradle to Cradle: Remaking the Way We Make Things" is a book by William McDonough and Michael Braungart that presents a new approach to design and manufacturing. The authors advocate for a system that mimics natural processes, where materials are continuously reused and recycled, rather than following a traditional linear model of production that leads to waste. The book introduces the concept of "cradle to cradle" design, which emphasizes sustainability and environmental responsibility. It encourages industries to create products that are not only safe for human health but also beneficial for the ecosystem, promoting a circular economy where materials are perpetually cycled back into use.
