铜冶炼产品碳足迹核算方法与优化路径.

Based on LCA life cycle method and IPCC factor method, an accounting method for product carbon footprint of copper smelting enterprises is proposed. Taking Guixi Smelter as the template, the whole process of copper smelting and the short process of miscellaneous copper smelting as the accounting object, and each production process as the accounting unit, the carbon footprint of the whole process of copper smelting is calculated. The analysis result shows that the carbon footprint of purchased electricity from copper smelting process accounts for 86. 64 %, and the carbon footprint of purchased electricity from recycled copper smelting process accounts for 53. 8%, which is the main contributor to the carbon footprint of copper smelting products* Based on the results of carbon footprint calculation, this paper puts forward the emission reduction link and optimization path of copper smelting enterprises.
