The interest and enthusiasm around the topic of green manufacturing, as a first step towards sustainable manufacturing, has encouraged a lot of research and investigation into this complex subject This book tries to give perspective to the term green manufacturing—how it is defined, where is “fits in” relative to sustainable production, what are the basic guidelines and tools of the trade for analyzing and practicing green manufacturing, and some examples of applications. The content reflects the research activities of the Laboratory for Manufacturing and Sustainability at the University of California, Berkeley, and is presented in the voice of the number of student researchers in the lab over the last few years. This work was motivated by the relatively little material on this topic in publication but the increasing interest from the public and our industrial and institutional partners. We are also motivated by the importance of this aspect of manufacturing, our curiosity, and the need for educational material in graduate course offerings in Mechanical Engineering at Berkeley and elsewhere.
