Battery disposal

There are many types of batteries and all of them contain materials that should be conserved through recycling.  In addition, many types of batteries are considered hazardous waste when disposed because of the harmful materials they contain.  However, most batteries can be recycled by appropriate facilities.  A quick safety tip before I tell you about battery recycling and disposal.  Keep batteries cool and put a piece of duct tape or electrical tape over the ends of the batteries when transporting them unless they are installed in a device.  Loose batteries can start a fire if they mix together in the wrong configuration.  In the US, many communities have a hazardous waste acceptance facility that will provide recycling or proper disposal for batteries.  Check with your local government for locations.  Two online organizations, Call2Recycle and Earth911 provide information on how and where to recycle batteries and other items.  A few bits of information on battery disposal:

• Rechargeable batteries can be recycled at some retail locations or at hazardous waste centers.  If the battery is not removable, take the entire device to the center. 
• Single-use batteries are safe to put in household trash but contain materials that can be recycled.  Most hazardous materials disposal centers will accept them.
• E-Bike batteries are accepted for recycling at many bike stores.
• Vehicle batteries are traditionally lead-acid batteries, so they contain significant amounts of lead and sulfuric acid.  Both are harmful to the environment (and people).  Return them to the store where you purchased them or drop them off at a hazardous waste collection center.
