Jena, July 7, 2026 – Improperly disposed of lithium-ion batteries are increasingly causing dangerous fires in waste collection vehicles and sorting facilities in Jena. Kommunalservice Jena (KSJ) is issuing an urgent warning against disposing of electronic waste in household trash.
- Topic: Fire hazard due to improper battery disposal
- Location of incident: Jena-Lobeda (fire in a waste compactor truck)
- Main cause: Lithium-ion batteries in residual waste
- Disposal points in Jena: Recycling centers, approx. 150 grey collection containers, retail return points
- Safety appeal: Always remove batteries from devices before disposal
Danger from lithium-ion batteries in residual waste
A large portion of the electronic waste collected in Jena passes through the primary treatment facility of Kommunalservice Jena (KSJ). There, old devices are sorted and prepared for recycling. However, if lithium-ion batteries end up in normal household waste, serious accidents can occur. The immense pressure during the compaction process in the waste vehicle can damage the batteries. This leads to a so-called “thermal runaway,” where stored energy is released abruptly. The result is severe fires or explosions.
A recent incident in the district of Lobeda illustrates these risks: A presumably improperly disposed of electronic device caused a fire in a compactor truck. Only through the rapid response of the sanitation workers and the emergency services could major damage be prevented. Just last week, a fire also occurred at a recycling facility in Thuringia.
Proper disposal of electronic devices: The rules for Jena
Electronic devices and loose batteries must never be thrown into the residual waste bin. The following instructions apply for safe and environmentally friendly recycling:
- Remove batteries: Batteries and rechargeable batteries must be removed from devices (e.g., smartphones, toys, greeting cards) before disposal, if possible.
- Use recycling centers: Larger old devices as well as damaged or swollen batteries belong directly at the KSJ recycling centers.
- Use collection containers: Around 150 grey collection containers are available throughout the Jena city area for small electronic devices.
- Retail returns: Retailers also accept old devices and used batteries free of charge, depending on their sales floor area.
Suitable drop-off points nearby can be easily found via the City of Jena map portal. Further information is also provided on the KSJ waste disposal website.
🛡️ Prevention & Guide: Safe handling of lithium-ion batteries
Lithium-ion batteries are highly efficient energy storage units but require caution in everyday life. To prevent damage and fires in your own home, the following safety rules apply:
- Use original chargers: Cheap imitations often lack the necessary shut-off mechanisms in case of overheating.
- Charge on a fireproof surface: Mobile phones, laptops, or e-bike batteries should not be charged on flammable materials such as sofas, beds, or carpets.
- Avoid extreme temperatures: Direct sunlight in summer or extreme cold permanently damage the sensitive cells and increase the risk of a short circuit.
- Sort out damaged batteries immediately: As soon as a battery becomes deformed, swollen, or smells strange, it must no longer be used or charged. Tape the terminals with insulating tape before transporting them to the recycling center.
