Tonnes of dumped waste in the Newark are has now been cleared after the council threatened landowners with court action.
Nottinghamshire County Council has removed dumped waste from two fly-tipping hotspots.
The first is land off Hawton Lane in Cotham and the second is an illegal waste site off Bowbridge Road in Newark.
In the first incident, in May 2018, the council investigated complaints that land off Hawton Lane was being used for general waste transfer, rather than for composting.
Investigations revealed that a general waste transfer station had started operating from the land, without planning permission.
Despite warnings, the waste was not removed.
After further discussions with the landowners, and the threat of prosecution proceedings, the waste materials were removed.
Sally Gill, group manager for planning at the council, said: "The county council is actively seeking to encourage the re-use and recycling of waste materials, but these activities should only be carried out in a suitable location and with the necessary planning permission and controls in place.
"If activities such as this are carried out without planning permission and cause unacceptable impacts, the county council will take enforcement action to require the use to cease and for waste to be removed, including prosecution if needed."
The second incident was an illegal waste site off Bowbridge Road, in Newark, in January 2015.
Council officers investigated the problem jointly with the Environment Agency.
Requests for the waste to be removed did not happen and the county council served an enforcement notice in May 2018.
The landowner subsequently lodged an appeal against this notice, but it was dismissed.
The waste has now been removed following the threat of prosecution.
Mrs Gill added: "Unauthorised waste development causes considerable disruption and nuisance to surrounding neighbours and businesses.
"As in this case, the county council will investigate all alleged breaches of planning control thoroughly and take appropriate action against the perpetrators and/or landowners to ensure that the breach of planning control is remedied, including formal enforcement action and prosecution where necessary.
"In this case, the waste was deposited without the landowner’s permission. The county council recommends that all landowners ensure that their premises are kept secure and regularly checked."
