Scientists, policy-makers, and the general public are becoming increas
ingly aware of environmental damage associated with the large and grow
ing material through-put required in modern industrial society. One ap
proach emerging in response to these concerns is called Industrial Eco
logy (IE). IE signals a shift from 'end-of-pipe' pollution control met
hods towards holistic strategies for prevention and planning of more e
nvironmentally sound industrial development. However, the broad umbrel
la of IE currently houses a diverse group of scholars, consultants, an
d environmentalists, who range in scope from those advocating incremen
tal changes in existing systems, to some promoting a total transformat
ion of industrial activity. This article presents a critical review of
the existing US literature on IE. We introduce and critique IE's prim
ary concepts, and analyse weaknesses and gaps in IE's conceptual frame
work. We also discuss the needs and potential for advancing if concept
s and projects in the future.
