Lithium-Ion Batteries in Recycling Waste Streams: The Growing Battery-Fire Risks Facing Recycling Centres

Lithium-ion batteries are now part of everyday life. From smartphones and power tools to e-bikes, disposable vapes, laptops, and household electronics, millions of battery-powered devices enter homes and workplaces every year.

But as the use of lithium-ion technology continues to rise, so too does a growing and often underestimated challenge for the waste and recycling industry: undetected lithium-ion batteries entering recycling systems and causing fires.

Across the UK, fires linked to incorrectly disposed batteries are increasing at an alarming rate, placing recycling operatives, waste facilities, collection vehicles, and emergency responders at significant risk. Fire services, councils, and recycling operators are now repeatedly warning the public about the dangers of disposing of battery-powered devices incorrectly.

The Hidden Dangers Inside Recycling Waste

One of the biggest challenges facing recycling facilities is that many lithium-ion batteries enter the waste stream unnoticed.

These batteries are often hidden inside:

• Disposable vapes
• Electric toothbrushes
• Toys
• Mobile phones
• Small power tools
• E-scooters
• Laptops
• Chargers and cables

Once mixed into general recycling or waste streams, the batteries can become crushed, punctured, overheated, or damaged during handling and processing. This can trigger thermal runaway — a dangerous chain reaction capable of generating intense heat, toxic gases, rapid flame spread, and re-ignition.

According to the National Fire Chiefs Council (NFCC), batteries hidden in electrical items caused over 700 fires in 2022 alone across recycling centres, waste facilities, and collection vehicles.

Recycling Centres Are Increasingly Vulnerable

Recycling facilities are particularly exposed to lithium-ion battery fires because of the environment in which they operate.

Waste streams often contain:

• Dry combustible materials
• Paper and cardboard
• Plastics
• Packaging waste
• Dust particles
• Large quantities of mixed recyclables

This combination can allow a small battery ignition to escalate into a major facility fire within seconds.

A recent fire at a UK recycling facility highlighted just how quickly these incidents can develop. A discarded lithium-ion battery sparked a fire that rapidly spread through surrounding waste materials, with operators warning that the entire building could have been lost without specialist fire-resistant infrastructure already in place.

Greater Manchester waste authorities have also warned that fires involving incorrectly disposed batteries continue to rise, with incidents occurring inside recycling vehicles and processing facilities.

Prevention Starts with Public Awareness — But It Cannot End There

Public education remains critically important.

Councils, fire services, and recycling organisations continue encouraging consumers to:

• Never place batteries in household recycling bins
• Properly recycle electrical items
• Use designated battery collection points
• Remove batteries from devices where possible

Somerset Council identifies household batteries, electrical items, and battery-powered devices as hazardous waste requiring careful disposal procedures.

However, even with public awareness campaigns, the reality is that lithium-ion batteries will continue entering waste streams undetected.

For recycling operators, this means one thing:

Appropriate fire suppression and containment solutions must be in place.

Why Traditional Fire Protection May Not Be Enough

Lithium-ion battery fires behave very differently from conventional fires.

Challenges include:

• Extremely high temperatures
• Thermal runaway propagation
• Re-ignition risk
• Toxic and flammable gas release
• Deep-seated battery cell reactions

Traditional fire extinguishers and suppression methods may struggle to fully control these incidents, particularly when fires occur deep within mixed waste streams or recycling machinery.

This is why specialist lithium-ion fire mitigation strategies are becoming increasingly important across:

• • Recycling centres
  • Waste transfer stations
  • Materials recovery facilities (MRFs)
  • Waste collection vehicles
  • Battery storage areas
  • E-waste processing sites

The Importance of Specialist Lithium-Ion Fire Suppression Solutions

As the waste and recycling sector adapts to the growing risks associated with lithium-ion batteries, operators are increasingly reviewing:

• Fire detection systems
• Thermal monitoring
• Fire compartmentation
• Staff response procedures
• Specialist suppression technologies

Solutions such as:

• Lithium-ion battery fire extinguishers
• EV fire blankets
• Fire suppression kits
• Containment systems can support emergency response procedures and reduce the risk of escalation during battery-related fires.

For facilities handling high volumes of mixed waste and recycling, preparation is no longer optional — it is becoming an operational necessity.

Lithium-Ion Battery Fires Are Now an Industry-Wide Challenge

The rapid adoption of battery-powered devices is transforming the fire risk profile of the waste and recycling industry.

While public awareness and safe recycling practices remain essential, recycling operators must also prepare for the reality that some devices will inevitably enter the waste stream undetected.

The question is no longer whether lithium-ion battery fires will occur within recycling environments.

The question is whether facilities are adequately prepared when they do.
