Lithium batteries have reshaped modern life. Since the 1990s, they have made smartphones, cordless tools, e-bikes, and electric vehicles possible. That same boom is creating a growing problem for waste and recycling facilities across the country, and the volume is only increasing.
More battery-powered products mean more end-of-life batteries being disposed of without proper handling or awareness of the risk. When those batteries reach your tipping floor, they bring serious safety risk with them.Ěý
Why Lithium-Ion Batteries Are Different
Lithium-ion batteries store a large amount of energy in a compact space. Under normal use, they are generally safe. The danger comes when they are damaged, crushed, or punctured, conditions that happen routinely in waste and recycling operations.
When a battery is damaged, it can overheat and trigger a chain reaction called thermal runaway. Once that starts, the battery can release heat, gas, and flames very quickly. If combustible materials like paper, cardboard, or plastics are nearby, a small battery fire can become a facility-wide incident fast.
Risks Every Facility Needs to Manage
Incoming Materials You Cannot Fully Control
Consumer awareness of battery disposal has improved, but habits have not caught up with volume. Batteries still arrive mixed into curbside bins, general trash, and recyclables. Your intake and sorting processes need to account for this reality.Ěý
Equipment Interaction
Compactors, balers, and shredders are the most common ignition points for battery incidents. A battery that survives collection may not survive processing. Review which areas of your operation create the most friction and heat and treat those zones accordingly.Ěý
Delayed Ignition
Thermal runaway does not always start on contact. A battery damaged earlier in the process can smolder for hours and ignite later, including overnight. Facilities that rely only on daytime fire watch are leaving a meaningful gap in coverage.
What Effective Battery Safety Looks Like
The scale of this problem is hard to overstate. According to a joint report from National 91TV & Recycling Association (NWRA) and Resource Recycling Systems (RRS), occur annually at U.S. recycling facilities with lithium batteries being a leading cause. Across the industry, several battery safety practices have proven effective at reducing risk and preventing incidents:
- Train early and often: Employees should understand the risks batteries pose, recognize signs of battery damage or thermal runaway, and know how to respond when a battery or battery-containing device is encountered.
- Establish handling and isolation protocols: When a battery is found, workers should know exactly how to safely remove, secure, and store it. Damaged, leaking, or smoking batteries should be stored separately in a away from other materials.
- Have the right safety tools on hand: Facilities should be equipped to respond quickly to battery incidents. A onsite is a strong starting point. These kits help contain and suppress thermal runaway events before they escalate.
- Consider a safer mixed battery collection system:High-volume operations are increasingly turning toĚýĚýthat do not require sorting or prepping batteries—reducing handling and creating a more controlled environment from intake to transport.
- Support proper battery recycling in your community: Promoting proper battery recycling and supporting battery collection networks reduces the number of batteries entering the waste stream improperly.
An Operational Priority
Battery safety is a shared responsibility, from the consumer who drops a battery in the recycling bin to the Materials Recovery Facility (MRF) worker sorting the line. The facilities best positioned to manage this challenge treat it as an operational priority, not just an emergency response problem.
