Abstract

Inventory analyses of manufacturing systems for Pb-bronze (JIS: CAC406), Pb-free bronze produced by Bi addition (JIS: CAC902) and copper sulfide-dispersed Pb-free bronze were assessed from the viewpoint of life cycle assessment. The results show that the manufacturing system of copper sulfide-dispersed Pb-free bronze significantly reduces such environmental impacts as energy consumption, global warming, acidification and resource consumption as compared with that of CAC902.
