Recycling of spent lead-acid batteries is leading to the production of slag which may be classified as hazardous waste because of its toxicity or lead (Pb) content.
Spent lead acid batteries are a rich source for the production of secondary lead. Pyrometallurgical operation currently practised exploiting this resource produces a lot of emission of oxides of sulphur and lead particulates causing atmospheric pollution.
