The Fraunhofer Institute has developed a comprehensive model of copper stocks, flows and recycling rates for the ICA. This complex, three-year study has resulted in a much-improved understanding of how copper is used and reused by society. The full publication “Dynamic Analysis of Global Copper Flows. Global Stocks, Postconsumer Material Flows, Recycling Indicators and Uncertainty Evaluation” contains additional information.
It is estimated that two-thirds of the 550 million tonnes of copper produced since 1900 are still in productive use (Glöser, 2013). Of this amount:
- Approximately 70 percent is used for electrical applications and 30 percent for nonelectrical applications.
- Around 55 percent is used in buildings, 15 percent in infrastructure, 10 percent in industry, 10 percent in transport and 10 percent in equipment manufacture.
