Over the years, batteries have moved from the simple carbon flashlight batteries to more modern and sophisticated types. The electronic revolution has caused several batteries of various chemistries to be developed for several applications ranging from video cams, digital cameras, cell phones and various electronic games and gadgets. Additionally, there are walkie talkies and other FRS (Family Radio Service) radios that have been around for quite some time that utilize batteries for their normal operations. With so many batteries around, the question comes up, should they be recycled or just dumped in a landfill?

The answer to this question requires an understanding of the chemistry of each battery and its effect on the environment. Some of the most common chemistries include Alkaline, Nickel Cadmium, Nickel Metal Hydride, Lithium Ion, Mercury and Lead Acid. There is also what is known as the rechargeable and the non-rechargeable or disposable battery. There is no battery with an electrolyte that is friendly to the environment. That being said, it is still not uncommon to fine piles of batteries finding its way to landfills. It is only some of the rechargeable ones that are finding its way back to a recycling plant.

Beside the toxic chemicals, batteries contain heavy metal which does not disintegrate easily. Some of these metals are also very corrosive. As a result, throwing batteries into landfills creates an environmental hazard. When these chemicals get into the earth it eventually finds itself into groundwater or soil used for growing food and results in contamination that cannot be cleaned up easily. Contamination of water and food have a direct impact on human beings as well as animals. Recycling therefore, reduces the amount of toxins that gets back into the earth to contaminate it.

Even though some authorities advise that single use batteries such as Duracell be tossed out in the garbage, it is still a source of concern by a lot of environmentalists. There are still traces of mercury and other toxic stuff that can present a problem over a period of time. Disposable batteries are more expensive to recycle than rechargeable batteries and as such, there are not many plants across the globe that actually recycles disposable batteries. With not much money to make from doing so, hardly anyone wants to invest money into plants that will not be economically viable.

Battery recycling actually is a plus for the environment and should be encouraged. Programs should be set up to educate the public on the subject and drop boxes or drop off depots should be made more available so that the public can fully participate in a functional recycling program.
