Centennial Evolution of Aluminum In-Use Stocks on Our Aluminized Planet

摘要: A dynamic material flow model was developed to simulate the evolution of global aluminum stocks in geological reserve and anthropogenic reservoir from 1900 2010 on a country level. The contemporary stock use (0.6 Gt or 90 kg/capita) has reached about 10% that known bauxite reserves represents an embodied energy amount is equivalent three-quarters present annual electricity consumption. largest proportions in-use are located U.S. (28%), China (15%), Japan (7%), Germany (6%) sectors building construction (40%) transportation (27%). Industrialized countries have shown similar patterns growth: once per-capita threshold level 50 kg, they kept near linear growth 5–10 kg/capita; no clear signs saturation can yet be observed. vary widely across countries: approximately 100–600 kg/capita industrialized an...
