ENGS 171 – Spring 2012






Course Description:


         By studying the flow of materials and energy through industrial systems, industrial ecology identifies economic ways to lessen negative environmental impacts, chiefly by reducing pollution at the source, minimizing energy consumption, designing for the environment, and promoting sustainability.

         The objective of this course is to examine the extent to which environmental concerns have affected specific industries, to evaluate the benefits of prevention over compliance, and to discern where additional progress can be made.  With the emphasis on technology as a source of both problems and solutions, a broad spectrum of industrial activities is reviewed, ranging from low-design high-volume commodities to high-design low-volume products.

         Student activities include a critical review of various articles, participation in class discussions, and a term project in design for the environment.


         Prerequisites: ENGS-21 (Introduction to Engineering) and ENGS-37 (Introduction to Environmental Engineering), or permission.

            Materials and the Environment: Eco-Informed Material Choice

            by Michael F. Ashby, Butterworth Heinemann, 2009

            (book in support of the CES EduPack EcoSelector software)

            (will be used as the basis for almost half the lectures)

            (a second edition may be out, but we will use the first in this course.)




            Pollution Prevention: Fundamentals and Practice

            by Paul L. Bishop, McGraw-Hill, 2000

            reprinted by Waveland Press, 2004

            (excellent topical coverage – highly recommended)


Software (access required):


Cambridge Engineering Selector (CES) 2012 EduPack EcoSelector, Granta Design Ltd.


            You are asked to download a copy of the CES EduPack software.  It is available on the “Materials” website at a web address that will be provided in class.  This version does not require a license key, but your computer clock will stop its functioning at the end of August 2013.


            To be able to run the software on an Apple computer, you will need Parallels, Fusion, VirtualBox, or Bootcamp running Windows.  You should be able to find instructions on any of these tools by searching online.  Bootcamp and VirtualBox are free.  Additionally, you will find this software installed on the desktops in the 210 MacLean computer instructional laboratory.         


Course Objectives:


1. Knowledge of fundamental ways by which industry can make progress in the direction of sustainability;

2. Understanding of principles of pollution prevention and design for environment;

3. Ability to perform limited life-cycle assessments;

4. Knowledge of current, ‘green’ technological initiatives in the auto industry;

5. Ability to decide in the face of incomparable quantities.


Honor Code:


            As always, students are expected to observe all aspects of Dartmouth’s Honor Principle, described on pages 44–46 of the Organization, Regulations & Courses.  Dartmouth College policy requires that any apparent violation of the Honor Principle be reported to the Committee on Standards.  The professor does not have any other choice, however uncomfortable he/she may feel.
