In the lead‑acid battery recycling system, acid collection is not only a basic operation but also a critical step to ensure environmental safety and resource circularity. The acid contains high concentrations of sulfuric acid, which, if improperly discharged during dismantling or transportation, can lead to serious ecological risks such as soil acidification and groundwater contamination. It may also corrode equipment, endanger worker health, and reduce the efficiency of subsequent lead recovery. By establishing closed‑loop collection systems, classified temporary storage facilities, and compliant transportation mechanisms, the risk of acid leakage can be effectively controlled. This allows for centralized, safe neutralization or reuse of the acid, driving the entire recycling industry toward greater environmental friendliness, safety, and sustainability.
