Comprehensive environmental assessment of typical Chinese industrial metal production processes.

ABSTRACT: To promote energy conservation and emission reduction, a quantitative assessment of pollutants from metal production is imperative. However, conventional life cycle assessment cannot provide detail environmental impact assessment for pollutants (e.g., waste water, waste gas, and solid waste) in metal productions. In this research, by analyzing 39 kinds of pollutants, a comprehensive environmental assessment (CEA) was conducted for 31 kinds of typical industrial metal-production processes in China. For CEA, Li, In, Cr, K, and Hg have higher environmental impact. Under global warming potential (GWP), 5 metals with higher carbon emission impacts are as follows: Nb > Ta > Mo > Cr > Au. A comprehensive analysis of CEA and GWP revealed that Cr has the most severe environmental impact (CEA: 74.99
