In recent times there has been a great increase in the production of refined lead through the recycling of lead acid batteries. Their ease of collection and high reuse rates represent a sustainable alternative, only if they are carried out in a proper way. If an environmental framework is not established to ensure adequate preservation of natural resources and protection of human health, their use would not be sustainable. In this context, this study established an environmental risk analysis in all stages of the lead acid battery recycling process in order to identify possible environmental risk scenarios. The study was carried out under the methodology based on the UNE 150006-2008 standard. The results obtained reveal that at a global level there is a moderate environmental risk with a characterization of 57.5%, however, with respect to the human environment, a significant risk of 68% ...
