Abstract
Copper and its alloy products are widely used in the world. Considering of sustainable development, people are focusing on how to exploit and utilize copper resource to meet the needs of global sustainable development. In this paper, we attempt to use the Substance Flow Analysis (SFA) and Stocks and flows (STAF) model to analyze copper flows and stocks through its all life cycle from production, manufacture, use and recycling, based on data from U.S. in 2012. The most interesting results are the following: (1) The production of refined copper from electrolytic and electrowon way is 491 and 471 Gg/year. (2) In manufacture stage, domestic refined copper production accounted for 62 % of total copper consumption. (3) The most of copper consumption in use stage is building construction, accumulation in 2012 is 1172.52 Gg/year. (4) In waste management stage, American scrap generated is 587.48 Gg/year, majority of them are exported. Domestic and imported scrap average copper content is up to 82.69 % which recycled in the stage of copper production and manufacture.
