  1. Environmentally Conscious Design & Manufacturing Class1: Introduction Prof. S. M. Pandit

  2. Contact Details Professor Sudhakar M. Pandit Office: 804 ME-EM Bldg. Phone: 906-487-2153 Fax: 906-487-2822 email: pand@mtu.edu Teaching Assistant: Huanran Xue Office: 401C ME-EM Bldg. Phone: 906-487-3396 Fax: 906-487-2822 email: hxue@mtu.edu

  3. Web-based Materials • The course web site can be accessed from: • http://www.me.mtu.edu/~pand • At the web-site, the following materials may be • retrieved: • - Lecture notes • - Homework

  4. Background ME 591: Engineering for the Environment Knowledge and skills that prepare engineers to address environmental quality and sustainability in their professional design and decisions.

  5. Course Objective ME 592: Environmentally Conscious Design & Manufacturing Factors, concepts, methods and tools important in design and manufacturing of discrete products to minimize the life cycle cost including environmental damage.

  6. Today’s Agenda • Course Syllabus • Course Overview • Course Expectations • Course Project

  7. Course Syllabus Keep in mind the following • This is a graduate level class-you will be expected to • pursue topics on your own. • Use the web and other references in addition to text • and notes. • This is a new area-leading edge-course is still evolving. • Instructor is only a facilitator, the course is a team effort.

  8. Overview - 1 Manufactured Product Effect on Environment Motivation • Solutions? • Assessment tools • Analysis tools • System modeling • Decision-making • Quantitative tools • ME464,569,466, • 566,667 Dimensions of ECDM Industrial Ecology

  9. Overview - 2 • Current Manufacturing practice is not sustainable. • The motivation to change is • compelling and • urgent • but the answers are not yet known.

  10. Motivation (why compelling) • CO2 levels • Consumption of fossil fuels • Environmental damage • Extermination of species • Loss of vegetation • Contamination of groundwater, lakes

  11. Motivation (why urgent) • Rate of fossil fuel depletion • Environmental and health hazards due to • Toxic wastes • Radioactive wastes • Acid rain • Landfill problems

  12. Motivation (why urgent) • 6000 metric tons of Carbon being burnt in various forms of fuel (up from 100 tons in 1860) 6000 tons Tons of C burnt 100 tons 1990 1860

  13. Pollution - 1 • CO2 rise Since 1750, carbon dioxide in the air has risen by more than 30%, due to human activities. It could double by the year 2065.

  14. Pollution - 2 • CH4 rise Each molecule of methane traps heat 20 times more effectively than a carbon dioxide molecule.

  15. Pollution - 3 This chart shows how much warming could be caused by each of the gases that human activities release. Carbon dioxide accounts for three fourths of the predicted increase in the greenhouse effect. Manufacturing activity and pollution

  16. Solutions • Getting from here to there: • Reduce energy / goods / services • Change the way we satisfy our needs • Option #2! • Improve understanding of ECDM • Look for solution strategies • Computer for reference and quantitative tools

  17. Industrial Ecology - 1 • Need to move towards “sustainability” • Industrial Ecology: • The means by which humanity can deliberately and rationally approach and maintain a desirable carrying capacity, given continued economic, cultural, and technological evolution.

  18. Industrial Ecology - 2 • Systems view: • The concept requires that an industrial system be viewed not in isolation from it’s surrounding systems, but in concert with them. It is a systems view in which one seeks to optimize the total materials cycle from virgin material, to component, to product, to obsolete product, and to ultimate disposal.

  19. Industrial Ecology - 3 • Factors to be optimized: • .. include resources, energy, and capital • Raw Materials • Manufacturing by-products • Waste streams • Economic dimension Thermodynamic view

  20. Dimensions of ECDM - 1 • Life Cycle Analysis • Economics • Energy • Quality & the Environment • Manufacturing Decision - Making • Waste Streams • Materials • Reuse / Recycling

  21. Dimensions of ECDM - 2 Raw Materials • Life cycle analysis of products • Design • Material selection, design and manufacturing • Reuse and recycling Manufacturing Use Post - Use

  22. Grading Majority of grade will be based on project Mid Term Exam 20% Final Oral Presentation 20% Final Written Presentation 30% Final Exam 30%

  23. Design Project • Continue project begun in ME 591 • Week 2 • - At MTU: Oral report from each project group. • Summarize progress to date and outline plans. • - GM sites: Videotaped presentation summarizing progress • to date and outlining future plans. • Week5 • Written project update due. Where do you stand, what has • been accomplished since last update, what is left to do?
