Green Engineering, 2/e, systematically describes today's environmentally preferable approaches to the design and development of processes and products. The authors have thoroughly updated their classic text to reflect today's most important trends and advances, and to discuss green engineering in the broader context of sustainability. They focus on helping engineers and students translate the abstract concepts of green engineering and sustainability to real designs, using today's most valuable quantitative design tools and performance metrics. This edition's extensive improvements include new software tools, more problems, and updated examples throughout. New and substantially expanded coverage includes: * Energy, climate change, and the laws regarding greenhouse gases * "Green" unit operations * Water conservation and pinch technologies, especially heat exchange * Lifecycle assessment and its regulatory uses * An all-new case study chapter, including biofuels and nano-technology cases
