This book highlights cutting-edge ecodesign research, covering product and service design, smart manufacturing, and social perspectives in ecodesign. Featuring selected papers presented at EcoDesign 2019: 11th International Symposium on Environmentally Conscious Design and Inverse Manufacturing, it also includes diverse, interdisciplinary approaches to foster ecodesign research and activities. In the context of Sustainable Development Goals (SDGs), it addresses the need for the manufacturing industry to design innovations for sustainable value creation, taking into account technological developments, legislation, and consumer lifestyles. Further, the book discusses the concept of circular economy, which originated in Europe and aims to increase resource efficiency by shifting away from the linear economy.
Focusing on product life cycle design and management, smart manufacturing, circular economy, and business strategies, and providing useful approaches and solutions to these emerging concepts, this book is intended for both researchers and practitioners working in the broad field of ecodesign and sustainability.
