Cambridgeshire residents are being told to never bin batteries or vapes.
Lithium-ion batteries from phones, vapes and e-bikes have caused seven bin lorries to catch fire in Cambridgeshire this year.
When batteries are disposed of in a wheelie bin, they can be crushed or damaged in the bin lorries which causes explosions and fires.
The Station Commander, Gareth Boyd, from Cambridgeshire Fire and Rescue Service:
"We are seeing an increase across the county of fires in waste collection trucks and these fires can be easily prevented by residents and businesses disposing of batteries correctly and separately from household waste."
