Used lead-acid batteries (car batteries) contain lead, lead compounds and sulfuric acid and are classified as hazardous waste under the Hazardous Waste Act 1989. They should not be disposed of with the regular garbage, as their toxic contents may leach from landfills into the environment. If recycled, these chemicals can be effectively recovered and made into new products, requiring significantly less energy than refining primary ore. Many scrap metal operators will pay a small amount for your old lead acid batteries.
Scrap metal recyclers are the best option for a business needing to dispose of lead-acid batteries regularly. Almost all scrap metal merchants will accept used lead-acid batteries. Collection services are also available at most landfills, transfer stations, and automotive workshops.
What Happens When It’s Recycled?
Approximately 96 percent of the various components of lead acid batteries are recoverable. The lead plates are restored back to new battery standards, the hard plastic casing can be melted and extruded to produce plastic pellets and the acid is neutralised and discharged.
