Development of iron and steel into eco-material

The technology of ferrous metals is well established. The use of iron and steel, in particular, is considerable and widespread. However, the processing of these materials is resource intensive and generates considerable pollutants, despite continual development. To maintain the use of these popular and versatile materials in the future will necessitate an increased attention to reductions in the consumption of natural resources and power, and greater sensitivity to the environment. This paper presents guidelines for ecological design of engineering product and processing of iron and steel in order to encourage greater processing and recycling efficiencies. It also describes the use of life-cycle analysis as a technique to assess the impact of change on society. The techniques are illustrated through the application of automobile manufacture and use. It goes further to stress the importance of relevant education in the principles of edodesign as fundamental to the effective implementation. The paper concludes with recommendations for the future.
