Ni-Cd batteries are one of the most recycled batteries in the world. Recycling companies can recycle 100% of the battery including the lead and cadmium. 

The recycling process begins by removing the combustible material, such as plastics and insulation, with a gas-fired thermal oxidizer. Polluting particles created by the burning process are eliminated by the plant’s scrubber before release into the atmosphere. This leaves the clean and naked cells with metal content.

The cells are then chopped into small pieces and heated until the metal liquefies. Non-metallic substances are burned off, leaving a black slag on top that a slag …
