摘要
运用生命周期评价的方法,对用二段法生产再生铜过程的环境协调性进行了研究,得到了再生铜生产过程中各工序的环境负荷数据.将再生铜与精矿铜生产的环境负荷进行了比较.结果表明,生产1 000 kg再生铜的能源消耗、温室效应、酸化效应和人体毒害分别为生产精矿铜的29.8%、25.7%、2.3%和2.4%,说明再生铜的生产过程具有良好的环境协调性.
The method of life cycle assessment was applied to the investigation of environmental compatibility of secondary copper produced with two steps. The environmental load data of every process in secondary copper production was obtained. The environmental load data of secondary copper were compared with those of the copper production with concentrate. The result indicated that the environmental effect of 1 000 kg secondary copper are 29. 8% ,25. 7% ,2. 3% and 2. 4% of those of copper out of concentrate with respect to the energy consumption, greenhouse effect, acidification effect, and human toxicity. So, the secondary copper would be a very environmentally acceptable material.
