Recycling cobalt batteries can have environmental impacts if not done properly. The process can result in the emission of pollutants, including greenhouse gases, toxic metals, and hazardous waste. Improper disposal of the waste generated during recycling can also have harmful effects on the environment. Not to mention recycling cobalt batteries requires a significant amount of energy. The process of recovering cobalt from batteries involves crushing, shredding, and melting the battery components, which can consume a lot of energy and contribute to carbon emissions.
