Recycling of used lead-acid batteries, provided it is done in an environmentally sound manner, is important because it keeps the batteries out of the waste stream destined for final disposal.Lead from storage batteries …
Lead-acid batteries contain sulphuric acid and large amounts of lead. The acid is extremely corrosive and is also a good carrier for soluble lead and lead particulate. Lead is a highly toxic metal that produces a range of adverse health effects particularly in young children.
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.
According to the World Health Organization (WHO), today around 85% of the world’s lead consumption is for the production of lead-acid batteries. The good news is that lead-acid batteries are 99% recyclable. However, lead exposure can still take place during the mining and processing of the lead, as well as during the recycling steps.
Thus, while the 99% recycling statistic is important, it may understate the potential for lead contamination via this process. However, the situation would definitely be much worse if these batteries were being landfilled, as a single lead acid battery in a landfill has the potential to contaminate a large area. Lithium-ion batteries
The lead extracted after breaking is either in the form of metallic lead grids or lead paste. Depending on the exact form of battery the lead paste will typically consist of some combination of PbO, PbSO 4, PbO 2, PbO 3 and metallic Pb.
All automotive batteries and 95 percent of industrial batteries are lead-acid secondary cells. Lead-acid batteries contain sulphuric acid and large amounts of lead. The acid is extremely corrosive and is also a good carrier for soluble lead and lead particulate.
