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.



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.



Today’s Agenda

•Course Syllabus

•Course Overview

•Course Expectations

•Course Project



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.



CO2 levels Consumption of fossil fuels Environmental damage Extermination of species Loss of vegetation Contamination of groundwater, lakes

Motivation (why compelling)



Rate of fossil fuel depletion Environmental and health hazards due

to » Toxic wastes» Radioactive wastes» Acid rain» Landfill problems

Motivation (why urgent)



1860

6000 tons

100 tonsTons of C burnt

Motivation (why urgent)

6000 metric tons of Carbon being burnt in various forms of fuel (up from 100 tons in 1860)

1990



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.

Pollution - 2



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 activityand pollution

Pollution - 3



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.



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

•Waste Streams•Materials•Reuse / Recycling

• Life Cycle Analysis

• Economics

• Energy

• Quality & the Environment

• Manufacturing Decision - Making



Dimensions of ECDM - 2

Life cycle analysis of products

• Design• Material selection, design and manufacturing

• Reuse and recycling

Raw Materials

Post - Use

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?
