Did you know that automotive batteries are the most recycled product in the world? 99% of lead acid batteries are recycled. However, every year, an estimated 1.8 million used batteries are not responsibly recycled. When a lead-acid battery is not properly recycled, it can cause lead, acid and mercury to be deposited into lakes, streams and landfills.
Advance Auto Parts makes it easy to be green and recycle your old lead acid batteries through our recycling program. Simply drop off your old battery at any of our stores (most vehicles, most locations, unless prohibited by law) and we’ll take care of the rest!
The first step battery recycling companies take when they recycle an auto battery is to put it through a hammermill, which effectively breaks the battery into small pieces. Those pieces flow into a container, with the heavier materials, including lead, falling to the bottom and the plastic remaining on top. The plastic is removed and the liquids are siphoned. The recycler then melts the plastic pieces and extrudes them into pellets which are then sold to manufacturers who use them to make new battery cases. The lead pieces are melted and poured into ingots, which are then melted down again to form the lead plates and other lead components of the battery. The old battery acid is processed and converted into sodium sulfate, which is used in detergent, glass and textile manufacturing. Battery recycling is considered a closed loop system because it can be repeated over and over again, allowing new products to be made from the old.
