Industrial ecology is a new system for describing and designing sustainable economies. Arising out of an ecological metaphor, it offers guidelines to designers of products and the institutional structures in which production and consumption occur, as well as frameworks for the analysis of complex material and energy flows across economies. 0 1997 Elsevier Science Ltd.

Introduction
Industrial ecology, as an emerging concept, plays several roles in shaping technological change as manifest in products. In its present state of evolution, industrial ecology takes many forms’ For some, it is a new, . powerful analytic framework, capable of capturing the systematic and dynamic characteristics of socio-economit systems.For others, it is a metaphor that leads to a new vocabulary* for talking about and making sense of the world. In this latter sense, industrial ecology is paradigmatic in nature. Institutionalist models of organized, social behavior can be illustrated, as in Figures I and 2, by a set of structures resting on a paradigmatic foundation in which dominant beliefs and social norms are con-

tained3.The specific forms of social structures arising at any time in history are the result of the diffusion of these culturally foundational (or paradigmatic) notions into more explicit organizational formsgovernment, church, family, corporate, etc.-and the shape of missions, tools, and authoritative relationships that characterize them. For some several centuries, industrial societies in the West havebeen driven by ‘ a dominant social paradigm (DSP) which will be further elaborated below (Table I). Arguably, the economic structures that have evolved within this paradigm (Figure Z) to produce the goods and services demanded by the marketplace have led to large negative impacts to the natural world. This set of structures is little informed by the natural world and a sense of society’ s placetherein. In this analytic world, industrial ecology

can serve as a means to improve positive knowledge about the socio-technological-natural system, particularly about material and energy flows. If there is to be a change that will reduce these impacts to atolerable level (Figure 2), many sociologists and social philosophers would argue that the paradigmatic base out of which the more practical institutions arise must shift3. In particular, it would seem that, to connect the natural world more directly to social thinking and action, the links that, are weak or missing in Figure 1 would need to be replaced by inward-leading flows to the action-producing...
