Looking to toss a spent lithium-ion battery? Or to discard electronic devices that are rechargeable but have outlived their usefulness?
Be aware those batteries -- especially powerful lithium-ion batteries found in many electronics -- can pose a fire danger when not disposed of properly, the Wisconsin Department of Natural Resources advises.
In the past month, significant fires were reported at recycling and solid waste facilities in Columbia County and Milwaukee, the DNR stated in a news release
Batteries could be the prime culprit in those fires, according to the DNR, as they can retain a considerable charge even when unable to provide enough energy to power the device -- and, when damaged, can spark or heat up.
"It only takes one lithium-ion battery to cause a huge fire and put workers and fire crews at risk," said Sarah Murray, DNR E-Cycle Wisconsin coordinator. "Recycling facilities that handle cans, bottles and paper are not designed to handle batteries and electronics. Paper, cardboard and other material can easily catch fire with a spark from a damaged battery or rechargeable device."
Added Greg Kaminski, Columbia County solid waste director, "Taking batteries and electronics to a drop-off site may be an extra step, but it's really important."
Some batteries, such as single-use alkaline batteries, are considered safe to put in the trash. But it's important to understand the batteries and how to store and dispose of them.
"With so many devices in our homes powered by so many different shapes and types of batteries, we know it can be confusing," Murray said. "We want to help everyone understand how to identify their batteries and where you can recycle batteries and electronics."
The DNR offers these tips:
-- Be aware that some batteries and battery-powered devices can pose significant hazards if damaged or tossed in the trash. Learn about the different types of batteries you have and how to manage them. The DNR has a household battery recycling guide at https://dnr.wi.gov/files/PDF/pubs/wa/WA1621.pdf to help.
-- Take used, rechargeable batteries to local collection sites. Check with battery retailers about their recycling programs or search for nearby sites through battery recycling organization Call2Recycle's website or by calling 1-877-2-RECYCLE.
-- Recycle old electronics through E-Cycle Wisconsin. Many small electronics can be recycled for free or traded for credit or cash. Go to the DNR's online list of collection sites and free mail-back programs.
-- Don't put electronics or rechargeable batteries in trash or recycling containers. Most electronics are banned from landfills and incinerators, and they cannot be recycled at the same facilities that recycle plastics, glass and paper.
-- When storing batteries for recycling, tape the terminals or put each battery in an individual plastic bag, which prevents batteries from accidentally sparking if terminals touch.
-- Store damaged -- swollen, bent, punctured or crushed -- batteries or devices in sand or kitty litter and, if possible, contact the manufacturer or Call2Recycle for instructions.
-- Do not try to remove non-removable batteries from devices, as this could damage the battery and cause a fire.
Note that businesses and institutions have special requirements to determine which types of batteries they have and manage batteries according to hazardous waste regulations.
