About 50 tonnes of rubbish was destroyed in a blaze at a waste disposal site in Wyberton.
Firefighters were called to Boston Waste Transfer Station, Slippery Gowt Lane, shortly before 3pm on Saturday.
Water was pumped through air vents at the station to put out the blaze which caused thick smoke to be seen from several miles away.
It took about five hours to put out the blaze and firefighters were able to damp down inside the station’s holding area in time for it to be re-opened on Monday.
Sean Kent, head of environmental management at Lincolnshire County Council, said: “Thankfully, nobody was hurt during this incident and relatively little damage has been caused.
“This kind of event is very rare but the safety procedures in place seemed to have worked well.
“At this stage we don’t know what started the fire, but this comes as a reminder to everyone that we need to be careful about what we throw away.”
