Battery recycling by type

Most types of batteries can be recycled. However, some batteries are recycled more readily than others, such as lead–acid automotive batteries (nearly 99% are recycled) and button cells (because of the value and toxicity of their chemicals). Rechargeable nickel–cadmium (NiCd), nickel–metal hydride battery (NiMH), lithium-ion (Li-ion) and nickel–zinc (NiZn), can also be recycled. Disposable alkaline batteries make up the vast majority of consumer battery use, but there is currently no cost-neutral recycling option. Consumer disposal guidelines vary by region. An evaluation of consumer alkaline battery recycling in Europe showed environmental benefit but at significant expense over disposal. Zinc–carbon and Zinc–air batteries are recycled in the same process.: 20–24 E.U. consumers recycled almost half of portable batteries bought in 2017. (EPA Environmental Resources)

Lead-acid batteries include but are not limited to: car batteries, golf cart batteries, UPS batteries, industrial forklift batteries, motorcycle batteries, and commercial batteries. These can be regular lead–acid, sealed lead–acid, gel type, or absorbent glass mat batteries. These are recycled by grinding them, neutralizing the acid, and separating the polymers from the lead. The recovered materials are used in a variety of applications, including new batteries. (University of Minnesota Extension)

The lead in a lead–acid battery can be recycled. Elemental lead is toxic and should therefore be kept out of the waste stream. (Penn State Extension)

The casing of a lead–acid battery is often made of either polypropylene or ABS, which can also be recycled, although there are significant limitations on recycling plastics. (USDA National Agriculture Library)

Battery recycling by location

Battery recycling is an international industry, with many nations exporting their used or spent lead-acid batteries to other nations for recycling. Consequently, it can be difficult to get accurate analyses of individual nations' exact rate of domestic recycling. (EPA Environmental Resources)

Further, in many countries, lead-acid battery recycling (chiefly from automobiles and motorcycles) is commonly done informally by individuals or informal enterprises, with little or no formal record-keeping, nor effective regulatory oversight. (University of Minnesota Extension)

Spent lead–acid batteries are generally designated as "hazardous waste" and subject to relevant safety, storage, handling and transport regulations, though those vary from country to country. A multilateral international agreement, the Basel Convention, officially governs all transboundary movements of hazardous waste for recovery or disposal, among the 172 signatory countries. (The U.S. is not a party, but has alternate arrangements with the Organisation for Economic Co-operation and Development (OECD), and with Canada and with Mexico (where it ships many lead-acid batteries for recycling). (Penn State Extension)

In 2006, the European Union passed the Battery Directive, one of the aims of which is a higher rate of battery recycling. The EU directive states that at least 25% of all the EU's used batteries must be collected by 2012, and rising to no less than 45% by 2016, of which at least 50% must be recycled. In 2020, 47% of batteries in the EU were collected for recycling. In 2023, the EU adopted new Batteries Regulation, which updates rules for calculating and verifying rates of recycling efficiency.
