& Alkaline Batteries – Just Throw them in the Garbage!
Alkaline Batteries – Just Throw them in the Garbage!
We used to think it was a shame to let any recyclable household item go
into the waste bin, so we were surprised to learn that it’s not
necessary to recycle alkaline batteries.
Batteries can be categorized as either single-use (primary cell) batteries or rechargeable (secondary cell) batteries. Each
type requires special instructions to ensure it’s properly recycled (or discarded). The majority of consumer batteries for
household use fall within these types:
Zinc-carbon
Button cell (lithium manganese or silver oxide)
Lithium (Li-ion)
Nickel-cadmium (NiCd)
Nickel metal hydride (NiMH)
Lead-based (automotive and non-automotive)
It turns out that some battery manufacturers, like
and , have eliminated all of the added mercury from its alkaline batteries, so they can now be safely discarded along with normal household waste. The other components of the batteries — steel, zinc and manganese — don’t pose health or environmental risks in the solid waste stream, according to Duracell, and those metals are difficult to recover from batteries.
We learned this by reading a blog written by an environmentally minded person named Will Taft —
— who did some research into the proper disposal of alkaline batteries. He even found this comment from the Consumer Electronics Association (CEA):
“Alkaline batteries are not recyclable. They’ll just be thrown out in a landfill, or at the most a hazardous waste landfill.”
Rechargeable batteries are a different story, though — they can contain mercury, cadmium, lead, and lithium, and therefore should be recycled. Car batteries and other lead-based batteries should also be recycled.
Alkaline batteries have several advantages: they last for a long time, perform well at high and low temperatures and have a long storage life. They can be stored at room temperature for two years and retain 90 percent of their original capacities.
It’s important to handle them properly, however. The Environmental Protection Agency (EPA) warns that if potassium hydroxide, which is contained within the cells of alkaline batteries, leaks out, it can cause chemical burns on skin or in your eyes.
And, Duracell warns people never to dispose of alkaline batteries by fire, because they could explode. Duracell also says not to dispose of large amounts of alkaline batteries together. Used batteries are often not completely “dead,” and grouping them can bring these “live” batteries into contact with one another, creating safety risks.
Most sources say that more than 150,000 tons of single-use batteries are tossed into landfills each year.
and we’ll take action to properly dispose of the batteries.
Buy rechargeable batteries!
