Are Batteries Recyclable?

Batteries require special recycling because they contain heavy metals, corrosive chemicals, and valuable materials that can be both hazardous to the environment and economically valuable when properly recovered. Common household batteries contain metals like lithium, cobalt, nickel, lead, mercury, cadmium, and zinc – materials that can leach into soil and groundwater if disposed of in landfills, potentially causing long-term environmental contamination. At the same time, these metals are finite resources that can be recovered and reused in manufacturing new batteries and other products, making battery recycling both an environmental necessity and an economic opportunity. Different battery chemistries require different recycling processes: alkaline batteries (AA, AAA, C, D, 9V) contain zinc and manganese; lithium-ion batteries contain lithium, cobalt, and nickel; lead-acid batteries contain lead and sulfuric acid; and button cell batteries may contain mercury or lithium. Modern recycling facilities use specialized processes like pyrometallurgy and hydrometallurgy to safely extract and purify these materials. The recycling process not only prevents environmental contamination but also reduces the need for mining new metals, conserving natural resources and reducing the environmental impact of battery production.

Never put batteries in regular trash or curbside recycling bins – they require special collection and processing. For household alkaline batteries (AA, AAA, C, D, 9V), take them to collection sites at electronics retailers like Best Buy, Staples, or Home Depot, which often have battery recycling kiosks near their entrances. Many pharmacies including CVS, Walgreens, and Rite Aid also accept household batteries. For rechargeable batteries (lithium-ion, nickel-cadmium, nickel-metal hydride), use the Call2Recycle program – search their website for nearby drop-off locations including libraries, schools, and retail stores. Car batteries (lead-acid) can be returned to auto parts stores, service stations, or automotive retailers, many of which offer core credits when you purchase a replacement. For specialized batteries like button cells from watches or hearing aids, take them to jewelry stores, watch repair shops, or hearing aid centers. Some municipalities hold hazardous waste collection events that accept all battery types. Before transport, tape over battery terminals with clear tape to prevent short circuits, and store different battery types separately.

Never throw batteries in trash or curbside recycling. Find a Call2Recycle drop-off location.
