The recycling of waste lead-acid batteries has become an important part of the sustainable development for lead-acid battery industry. This study utilizes Life Cycle Assessment (LCA) to analyze the environmental impacts of regeneration technologies for lead alloys from waste lead-acid batteries and the whole life cycle of end-of-life pollution treatment. The article also compares the results with the process of producing batteries via pig lead from waste lead-acid batteries and primary materials. It shows that most of the environmental burden comes from the procedure of lead paste smelting and alloy preparation resulting from the indirect effects of auxiliary materials and energy power,with Global Warming Potential to be 60% and 30%,Acidification Potential to be 33% and 54%,and Human Toxicity Potential to be 28% and 57%. The comparative results show that the process using primary materials exhibits greater environmental impacts,with the biggest normalized results of human toxicity potential to be 2.42*10~(-11),eutrophication potential to be 1.26*10~(-11),and acidification potential to be 1.08*10~(-11). The environmental impact of the primary lead production takes the most within the process of using primary materials to produce batteries. Compared with the regeneration of lead from waste batteries via pig lead to produce lead alloys,direct regeneration of lead alloys from waste batteries shows better environmental performance,and is helpful to form a closed loop for battery manufacturers. So this technique is worth being promoted. In the future,we should encourage the recycling of waste lead-acid batteries instead of using primary materials to produce new batteries. Meanwhile,further steps for reducing the environmental impacts of resources and energy used during the recovery process will bring greater environmental benefits.
