What should residents do with common household alkaline batteries (non-rechargeable)?
Regular household (non-rechargeable) batteries are rarely considered to be hazardous since only very small amounts, if any, manufactured today (since 1994) contain mercury. Alkaline batteries are composed primarily of common metals – steel, zinc and manganese – and do not pose a health or environmental risk during normal use or disposal. Proven cost-effective and environmentally safe recycling processes are not yet universally available for alkaline batteries. Implementing a collection and disposal program using the household hazardous waste vendors would be very costly. If you are making a trip taking other items to the Household Hazardous Waste Facility, take them along; otherwise, it is not worth the gas to make the trip there and they can safely be disposed of in the garbage.
