What kind of license do I need for waste battery recycling?

Mainly depends on the specific local policy

According to the "Management Measures for Hazardous Waste Operation License", units engaged in hazardous waste collection, storage, disposal of business activities should hold a hazardous waste operation license issued by the environmental protection department. Units and individuals without a license to collect, store and dispose of hazardous wastes will be severely punished, and if there are dangerous consequences, they will be held criminally liable according to the law.
