The standard stipulates the ceiling value for the discharge of water and air pollutants and requirements on monitoring of battery manufacturing enterprises and special discharge limits of water and air pollutants for key areas.
The discharge of other pollutants of odor pollutants and environmental noise by battery manufacturing enterprises shall observe corresponding applicable national pollution discharge standards, and the identification, treatment and disposal of solid wastes hence generated shall observe applicable national standards on solid waste pollution control.

In this study, we demonstrate a practical approach for valorizing battery manufacturing wastewater, characterized by high salt concentrations. This approach overcomes the osmotic pressure limitation while ensuring high overall yield and purity.
EPA promulgated the Battery Manufacturing Effluent Guidelines and Standards ( 40 CFR Part 461) in 1984 and amended the regulation in 1986. The regulation covers dischargers.
Transition metal ions (Ni 2+, Cu 2+, and Cd 2+) are recovered by 90 % from wastewater. Transition metal ions are enriched to a 43-fold concentration, achieving 99.8% purity. Leveraging the latent value within battery manufacturing wastewater holds considerable potential for promoting the sustainability of the water-energy nexus.
