A Handbook of Industrial Ecology

Edited by Robert U. Ayres and Leslie W. Ayres

Industrial ecology is coming of age and this superb book brings together leading scholars to present a state-of-the-art overviews of the subject. Each part of the book comprehensively covers the following issues in a systematic style: the goals and achievements of industrial ecology and the history of the field; methodology, covering the main approaches to analysis and assessment; economics and industrial ecology; industrial ecology at the national/regional level; industrial ecology at the sectoral/materials level; and applications and policy implications.

Chapter 29: Long-term world metal use: application of industrial ecology in a system dynamics model

Detlef P. van Vuuren, Bart J. Strengers and Bert J.M. de Vries

Subjects: business and management, management and sustainability, economics and finance, industrial economics, environment, ecological economics, environmental management


Detlef P. van Vuuren, Bart J. Strengers and Bert J. M. de Vries* Over the last century, the exploitation of material resources has grown enormously. Currently, western economies use about 20 to 40 metric tons of raw materials per person per year (Adriaanse et al. 1997). While high material consumption rates certainly have contributed to the high living standards in large parts of the world, their enormous throughput has also raised questions with regard to the sustainability of current use. Especially during the energy crises in the 1970s, several authors have pointed out the risks of depleting reserves of high-grade resources; predictions were made that the world would run out of some raw materials in 50 years (for example, Meadows et al. 1972). At the moment, attention seems to have shifted to the question of whether ore grade depletion might aggravate the environmental problems associated with metal production (Tilton 1996). Clearly, exploitation of raw materials requires a sizeable amount of global capital and energy inputs and causes different sorts of environmental problems in mining, transport and upgrading. In addition, virtually all materials ultimately return to the environment, creating fluxes of substances that are potentially harmful to the environment. Industrial ecology intends to introduce integrated responses to this type of problem. System dynamics models form one of the tools that contribute to this. In this chapter, we will focus on a system dynamics model for an important type of material use, that is, metals. Earlier, production and consumption of metals...
