Copper resource trends and use reduction measures in China
Copper is a strategic Chinese resource.Resource bottlenecks and environmental constraints have become increasingly prominent due to the large consumer demand and high external dependence.This study analyzes the trends of Chinese copper resources using a stocks-based prediction model based on a material flow analysis and then compares the resource and environmental impact of three measures using scenario analyses.The results show that after 2025,secondary copper will exceed imported copper as a main copper source.Demand for copper resources will peak in 2040 and then stabilize.Changes in the consumption structure are effective in the short term with the effect of reduced per capita resource consumption more evenly spread.Improved resource recovery is not effective in the short-term but is effective in the long-term.Therefore,China must control domestic copper production capacity and vigorously develop the recycling industry from 2010 to 2030.Structural adjustments of resources and reduced per capita resource use will help in the short term,an efficient resource recycling system is needed in the long run.
