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

This book, which includes a quantitative demand forecasting model, is based on a study commissioned by the International Institute for Environment and Development (IIED) for the World Business Council for Sustainable Development (WBCSD) fills that need for the first time. Among the conclusions of the study are the following. The medium-term prospects for copper producers and copper consuming industries include (1) more intensive exploration into more remote regions, (2) utilization of lower grade ores resulting in more mine wastes and associated waste disposal problems, (3) more intensive mining efficient ore reduction processes, (4) dramatic price increases when the current glut works itself out, (5) significant changes in the patterns of consumption (increasingly electrical applications), (6) sharp increases in the need for recovering and recycling old scrap copper in the future, (7) a significant buildup of copper and by-products (especially arsenic) either in use or in the human environment. Similar implications can be drawn for two other scarce and toxic metals - lead and zinc - often found in geological association with copper

Industrial Ecology is perhaps the first serious attempt to go beyond general statements regarding the desirability of 'clean technology' and to assess realistically and quantitatively the range of practicable possibilities for reducing materials extraction, consumption and waste. This major new book examines strategic options for reducing wastes and pollution and increasing the productivity of materials. Using an industrial ecology perspective, the authors analyse thirteen generic cases of material, beginning with four families of metals (aluminium, chromium, copper and zinc), several families of chemicals (phosphates and fluorine; suphur-based, nitrogen-based and chlorine-based), silicon and several different types of waste. Opportunities for creating 'industrial ecosystems' by deliberate design are discussed as well as the use of low-value by-products as feed stocks for useful products. In addition to surveying the technological possibilities, the authors also consider the public interest, institutional barriers and the range of possible alternatives that might be applicable. Environmental scientists, economists, practitioners and policy makers will welcome Industrial Ecology's integrated approach and the emphasis which it places on resource productivity, materials cycle optimization and waste minimization
