Lead from recycled lead–acid batteries has become the primary source of lead worldwide. Battery manufacturing accounts for greater than 85% of lead consumption in the world and recycling rate of lead–acid batteries in the USA is about 99%. Therefore, battery manufacturing and recycled lead form a closed loop.
Lead-acid batteries are the most widely and commonly used rechargeable batteries in the automotive and industrial sector. Irrespective of the environmental challenges it poses, lead-acid batteries have remained ahead of its peers because of its cheap cost as compared to the expensive cost of Lithium ion and nickel cadmium batteries.
Inappropriate recycling operations release considerable amounts of lead particles and fumes emitted into the air, deposited onto soil, water bodies and other surfaces, with both environment and human health negative impacts. Lead-acid batteries are the most widely and commonly used rechargeable batteries in the automotive and industrial sector.
It is evident that the segregation and independent treatment of the most polluting effluents from dismantling and washing lead-acid batteries means that much of the rest of the effluents can be discharged; this therefore simplifies their treatment and minimises the environmental impact.
Regarding the treatment of hazardous waste, lead-acid batteries are the most damaging waste fraction. Phasing out lead-acid batteries for lithium-ion is currently too expensive to be feasible in the unregulated sector, and the capacity of governments to enforce such a measure is limited.
The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the advanced processes already being implemented by some environmental managers.
