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.

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.

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)

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.

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 its 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

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

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?
