This book presents technologies as well as digital methods and tools which help to foster future eco-factories. After setting an overall framework, the different chapters cover various topics from the perspective on single machines and process chains, technical building services (e.g. compressed air, energy storage) and the factory as a whole. The editors sincerely want to thank all involved authors from industry and academia for their valuable contributions, which completed this comprehensive and interdisciplinary perspective on eco-factories of the future.
