 Did you know that there are more than 250 thousand tons of (or 3.5 billion) batteries produced annually for the North American consumer market? Many of these batteries eventually make it into landfill sites, approximately 600 tons of batteries per day.
They are not recycled simply because the cost of recycling is much higher than mining the raw materials. What happens after that? Over time the battery cases become breached and dangerous heavy metals leach into the surrounding ground and water. The most toxic metals are mercury, cadmium and lead, metals found in many common types of batteries.
Below is a summary of some popular types of battery and their recommended disposal method:
Alkaline contains mercury and potassium hydroxide (corrosive). Newer alkaline batteries have much less mercury content than old alkaline batteries. For this reason many landfill bans have been lifted for Alkaline batteries. Check with your local hazardous waste program for specifics concerning disposal of alkaline batteries.
Carbon-Zinc has no mercury and can generally be thrown in the garbage.
NiCad (Nickel-Cadmium) are rechargeable batteries popular with consumers. These batteries must be recycled. They should never be put in the garbage.
Nickel metal hydride provide less of a threat to the environment than NiCad batteries but manufacturers or third party recyclers offer to recycle these batteries and therefore should be recycled. There are several mail-in programs that can be found on the internet.
Lithium Ion are recycled same as nickel metal hydride.
Button Cell contains small amounts of mercury that has been added to prevent gases that could rupture the battery case. These batteries could be classified as hazardous waste depending on the size of the battery. They can be taken to jewellery stores for recycling or other places where the spent batteries can be exchanged for new.
Lead Acid can be taken to auto parts stores and any store they can be purchased at.
Before taking batteries for recycling or disposal the batteries should be sorted / separated by type. Place each type into a separate plastic bag for easier handling.
Always be careful when handling spent batteries. Some suffer from corrosion. In rare instances spent batteries may explode if handled incorrectly. Never store or hold new batteries together with old.

Care should be considered when using mail-in programs as there are strict regulations about transporting loose, used or old batteries by air. Batteries should be individually wrapped iand securely sealed n plastic bags or the metal terminals should be covered with nonconductive tape to prevent contact with other metal objects. Otherwise, the metal parts can touch and cause dangerous discard.
National retail chain, Batteries Plus, accepts all batteries back for recycling. Battery Solution provides collection boxes for a fee to recycle household, single-use alkaline batteries. Call2Recycle offers free collection boxes for recycling rechargeable batteries. Communities, businesses, and retailers can enroll in the program at no cost. Boxes come with plastic bags, pre-addressed shipping label and postage prepaid. Shipment is by ground to comply with federal regulation for shipping used batteries.
I am often confused as to what to do with different types of battery but this blog has defiantly made things a lot more simple. I hate throwing things away knowing that they will end up in landfill just leaching chemicals and causing damage to the environment.
