(Radio Iowa) – Everything from computers to power tools now contain lithium batteries and that has created a sometimes explosive situation for waste haulers. Ames Resource Recovery Plant assistant superintendent Mark Peebler says it is very dangerous to throw lithium batteries into the regular garbage. “There’s several different cells in there, and each cell is separate. When those cells get exposed and exposed to each other, we’ll say if it gets broken or cut in the center, that causes that to create a thermal reaction,” he says. Peebler says the batteries get cut by the compactors in garbage trucks and the thermal reaction sets the trucks on fire. He says the batteries may no longer run your weed wacker, but they aren’t out of power when you toss them.

“I think a lot of people, when they throw those batteries away, they think that the battery is just dead. That’s not generally the case,” he says. “Generally, there’s still 80 percent of the original energy still stored in that battery. It’s just on and it’s just not enough to power that device that you’re using.” He says the batteries have been developed to deliver more juice, which makes them more dangerous if properly recycled. “Everybody wants them to be more powerful and to last longer, and by doing that, it increases the thermal reaction and the energy that’s stored in a smaller space,” Peebler says. “So then that, it makes it harder, harder to recycle them. And technology is constantly changing. So that’s one of those things on the recycling side that we have to make sure that we keep up with and that they get disposed of the right way.”

Peebler says they keep containers at their plant where people can drop off the lithium ion batteries for recycling. The Dubuque Metropolitan Area Solid Waste Agency was just awarded up to four million dollars in federal funds to construct a new battery recycling and collection hub at its planned customer convenience center. Agency Administrator Ken Miller says lithium batteries have caused expensive fires in their garbage haulers’ trucks. He says the batteries can also cause dangerous fires in the landfill. “When our heavy equipment runs over the battery, not knowing it’s in there, then that causes the same reaction as it would if it came inside, into contact with the mechanized system within the garbage truck,” he says. He says all the garbage in the trucks and landfill provides fuel so the battery fire can quickly grow. Miller says employees sorting the batteries can also be injured if one starts on fire. The new facility gives them a warm safe place to separate and sort the lithium batteries. The batteries are then sent off to be recycled.

“There are specifically designed battery recycling facilities that will then recycle those materials to recapture the metals and stuff. This is a lithium so they can be reused again. It just depends on how the battery comes into us. Loose batteries we ship to one processor. Battery containing devices go to our electronics recycler.” Miller says. He says some agencies are developing high-tech systems to battle the fires that start from lithium batteries, but prevention is a better idea. “Using A-I camera technology and water cannons to be able to suppress, detect and suppress the fires as they begin, rather than, you know, waiting until the whole building is engulfed,” he says. “But the idea is to not have to utilize those systems by keeping them out of the waste and recycling, you know, the curbside waste and recycling streams altogether.”

Peebler and Miller says you can help by keeping lithium batteries out of the garbage and checking with your local waste hauler for lithium battery recycling options.
