Processing Lead-Acid Batteries for Recycling
The collection and processing of lead-acid batteries should be done with extreme care on the part of the recycler. It is important not to break or puncture the plastic casing of the battery. If not handled properly, used lead-acid batteries can leak or spill and contaminate soil and groundwater. Both lead and acid may be harmful to humans and the environment.
Lead-acid batteries should be placed on either pallets, or in large polyethylene totes without drains. Batteries are normally stacked upright three high on the pallet with a corrugated sheet or shock-absorbing material between each layer of batteries. Stack batteries pole side out to increase stack stability. Once the pallet is full of batteries place shrink-wrap around the entire pallet of batteries to prevent them from moving or falling during the loading, transportation and unloading process. Once the batteries and pallet are shrink-wrapped, place one or more plastic bands around the batteries to provide for a more secure load.
Batteries should always be stored indoors to eliminate contact with water and to avoid extreme temperatures that can cause the casings to crack. Prior to loading the pallets of batteries into the trailer, scatter lime on the floor of the trailer to neutralize any acid that may be spilled during storage and transportation. Place cracked or leaking batteries in an acid-resistant, leak proof container.
Check with the U. S. Department of Transportation for regulations on packaging and transportation of lead-acid batteries. The regulation number "173.159" will need to be typed into the "Search" box on the DOT site.
