Substitution has long been a common remedy for materials shortages. This study, originally published in 1983, uses tin to examine how and why substitution takes place. To provide insights into the tin industry and the practice of substitution, the case studies in this title examine three tin-using industries--beverage containers, solder, and tin chemical stabilisers. Overall, the contributors to this volume raise fundamental questions concerning the techniques for both short- and long-term forecasts of materials requirements in the industrial sector. This title will be of particular interest to students of Environmental Science.
