Environmentally Conscious Design & Manufacturing (ME592) Date: March 6, 2000 Slide:17 Industrial Ecology - 1 l 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.

Environmentally Conscious Design & Manufacturing (ME592) Date: March 6, 2000 Slide:18 Industrial Ecology - 2 l 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.
