Discarded batteries in the recycling collection are believed to be the cause of two fires in 100-tonne piles of recycled waste in Boston in recent weeks.
One of the fires required attendance by the fire brigade and caused damage to the waste transfer station, with two burned out laptops, complete with batteries, discovered among the embers.
Discarded batteries buried deep within the massive heap of combustible material shorted and became the source of ignition.
A mobile phone battery is believed to have started another fire in recent weeks.
A spokesman for Boston Borough Council said: “We are now issuing advice to residents asking them not to recycle batteries or any electrical goods in their recycling collection or their general waste.”
