6 Frequently Asked Questions about “Main polluting elements of lead-acid batteries”
Does a waste lead acid battery contain Pops?
This guidance applies to waste automotive, industrial and portable lead acid batteries. It does not apply to other types of waste battery. The plastic cases of waste lead acid batteries may contain persistent organic pollutants (POPs). You can identify if a waste lead acid battery may contain POPs by checking: Where the battery case is made of :
Can I repackage a lead acid battery?
You may only temporarily store or repackage waste lead acid batteries containing POPs before: You must also sort lead acid batteries with polypropylene cases, that should not contain POPs, from those with other cases. You must also hold an environmental permit or exemption that allows this activity.
Can I export lead acid batteries under my existing notification?
You can continue to export lead acid batteries under your existing notification if you can prove the following to the Environment Agency. The POPs in the plastic are being destroyed in line with this guidance.
Can I export lead acid batteries from England?
Where POPs will be destroyed, you may include recovery of lead or recycling of plastic that does not contain POPs. The combination of hazardous waste and POPs severely restricts both destination countries and allowed waste management options. You must notify the export of lead acid batteries from England to destinations outside the UK.
What are the environmental risks of lead-acid batteries?
The leakage of sulfuric acid was the main environmental risk of lead-acid batteries in the process of production, processing, transportation, use or storage. According to the project scale the sulfuric acid leakage rate was calculated to be 0.190kg/s, and the leakage amount in 10 minutes was about 114kg.
What happens if you recycle a lead-acid battery?
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.
