Our design, production and consumption patterns must be redefined to address the new challenges faced by our society. Problems generated by traditional "industrial production" cannot be solved with the same "industrial" thinking paradigms. Eco-Design (Design for the Environment, DfE) has been widely developed and is currently taught and used in many design fields. However, DfE has recently evolved to Design for Sustainability (DfS, D4S) which not only considers environmental, but also social and economic aspects. This book discusses the use of Biomimicry as a tool for D4S. Historically, many types of bio-inspired design have imitated form and function from nature. Today, imitation of processes or ecosystems is proving very useful in rethinking our world. Biomimicry is redefining the way we design products and services. Diverse study cases in industry and education were analyzed and discussed. The book provides insight into new and exciting multidisciplinary design possibilities and is especially useful for biologists and ecologists interested in design, as well as designers, students, educators, and anybody interested in new ways to make our world more sustainable.
