The purpose of this class is to address the issue of sustainability from an engineering perspective. First we review the concept of sustainability from several points of view including economics, ecology, and engineering. This discussion includes the widely used “Triple Bottom Line” approach of industry. The current state of the “Science of Sustainability” will be reviewed. We then develop a resource accounting perspective in some detail with the emphasis in four areas:
1) energy resources analysis, energy flows, balances, efficiencies, primary energy use, energy return on investment, net energy analysis, renewable energy.
2) material resources analysis (including not only the materials used in the delivery of products and services, but also the effects on major material cycles such as carbon, water, and nitrogen). This approach will be expanded to aggregate both fuels and non-fuel materials by using an exergy analysis approach.
3) life cycle assessment of products and services (including variations on the method such as input-output models, hybrid models, and exergy models and a critique of the utility of LCA).
4) accounting for the role of ecosystem services in supporting industrial activities.
The class uses our new book Thermodynamics and the Destruction of Resources (Cambridge University Press, 2011) and builds these topics from a solid basis. Examples will be taken from diverse areas but with special attention to current and emerging chemical and manufacturing processes and product analysis. Participants are encouraged to bring sample cases for discussion, and class will include time for hands-on LCA for products and services of your choice.

About the Lecturers
Timothy Gutowski received his Ph.D. in Mechanical Engineering from the Massachusetts Institute of Technology in 1981. Currently he is a Professor of Mechanical Engineering at MIT and a member of the Laboratory for Manufacturing and Productivity (LMP). He was the Director of the LMP from 1994 to 2004, and the Associate Department Head for Mechanical Engineering from 2001 to 2005. From 1999 to 2001 he was the chairman of the National Science Foundation/Department of Energy panel on Environmentally Benign Manufacturing. He has over 150 technical publications and seven patents and patent applications. He is the editor of the book Advanced Composites Manufacturing, published by John Wiley in 1997.
Professor Gutowski’s research over the past 10 years has focused on the environmental issues associated with processes, products, and services. His work on manufacturing processes is extensive, including the analysis (energy and materials) of such processes as machining; grinding; casting; forming and injection molding; advanced machining processes such as abrasive waterjet and electrical discharge machining; semiconductor and MEMS processes such as CVD, PECVD, and various etching processes; and nano-materials manufacturing processes such as HiPCO and CVD. In addition, he has worked extensively on recycling processes, systems, and product design for recycling, as well as on product remanufacturing and energy savings. His work also includes the energy payback analysis for new energy systems during growth, and LCA applied to personal life styles called “Life Style Analysis”.
