Patterns of Iron Use in Societal Evolution

摘要: A dynamic material flow model was used to analyze the patterns of iron stocks in use for six industrialized countries. The contemporary stock remaining countries estimated assuming that they follow a similar pattern per economic activity. Iron have reached plateau about 8-12 tons capita United States, France, and Kingdom, but not yet Japan, Canada, Australia. global average determined be 2.7 capita. An increase level 10 over next decades would deplete currently identified reserves. subsequent saturation open long-term potential dramatically shift resource from primary secondary sources. observed implies developing with rapidly growing lower recycling domestic scrap hence greenhouse gas emissions saving than countries, fact has been addressed sufficiently climate change debate.
