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.
NUOVOpb, an EU-supported project, successfully separated the spent materials from LABs, ‘recovering’ them in a water-based recycling process to produce ‘battery ready’ lead oxide. The process offers a start-up cost around one seventh of existing LAB recycling and a comparable operating cost to existing recycling methods.
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.
The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.
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.

Recycling Lead-Acid Batteries and Associated Pb Pollution
Lead-acid batteries (LABs) were the first rechargeable electric battery marketed for commercial use and have remained an industry standard ever since. This is true despite the fact that LABs offer low energy density, typically operating at 30%-40% of the theoretical limit, compared to 90% for lithium-ion batteries. [1] The persistence of LABs in the commercial market stems mainly …
