Exports of Spent Lead Acid Batteries (SLABs)

SLABsLead acid batteries are those made of lead plates, usually encased in plastic and containing an acid electrolyte, such as sulfuric acid. These batteries are commonly found in cars, trucks, boats, and have many other applications. They typically have a life span of 3 to 10 years. Spent lead-acid batteries (SLABs) must be properly handled to avoid breakage, spillage and leaks, which can cause lead and/or acid contamination of the environment.

Nearly 90 percent of all lead-acid batteries used in the U.S. are recycled. Almost any retailer that sells lead-acid batteries collects used batteries for recycling, as required by most state laws. Reclaimers crush batteries into nickel-sized pieces and separate the plastic components. They send the plastic to a reprocessor for manufacture into new plastic products and deliver purified lead to battery manufacturers and other industries. A typical lead-acid battery contains 60 to 80 percent recycled lead and plastic.

Although the vast majority of domestic SLABs are recycled in the US, some are exported to Canada, Mexico, and other countries for reclamation. In July 2010, EPA revised Resource Conservation and Recovery Act (RCRA) rules regarding the export of spent lead-acid batteries. The revised regulations provide stricter controls and greater transparency for exports of SLABs, and they ensure that SLABs are sent to countries and reclamation facilities in those countries that can manage the SLABs in an environmentally sound manner. For example the new regulations add export notification and consent requirements. This rule makes EPA's RCRA hazardous waste transboundary shipment regulations more consistent with those of the Organization for Economic Cooperation and Development (OECD).
