Environmentally Conscious Design & Manufacturing (ME592)
Date: March 6, 2000 Slide:7
Course Syllabus
•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.
Keep in mind the following

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

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.

CH4 rise
Each molecule of methane traps heat 20 times more effectively than a carbon dioxide molecule.

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

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.

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.

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?
