Achieving environmental stewardship in iron and steel sector through application of life cycle assessment

摘要: The aims of this thesis are: (1) To develop improved knowledge and understanding of material flows and life cycle assessments of the iron and steel industries and (2) suggest policy directions based on the knowledge and understandings gained. It is hoped that improved environmental performance and environmental stewardship for the iron and steel material cycles will be outcomes of the work reported here. The metrics used include materials flow analysis (MFA) and life cycle assessment (LCA). The mining and metals sector provides materials that are essential elements in a wide range of goods and services. By virtue of their inherent qualities (including strength, chemical resistance and lustre), minerals and metals create value by meeting human needs. The mining, refining and recycling industries, which make metals available for use in human societies around the globe, are under increasing pressure to …
