A director of Stud Recycling has been jailed for six months following a trial at Airdrie Sheriff Court.
Joseph Cahill and Stud Recycling admitted the illegal handling of controlled waste at Easter Dunyston Farm, Airdrie, without a licence.
Tonnes of mattresses and tyres had been dumped at the farm between 14 February and 20 November 2012.
The court heard that around 45,000 tyres had been dumped on the site.
As well as the jail sentence, the company was also fined £12,000.
Procurator fiscal Sara Shaw said: “This company, under the direction of Cahill, was operating illegally on a site that they had refused to make fit for purpose at the expense of, and with significant risk to, the local environment.
“They kept waste tyres in fields creating an eyesore and without a licence to do so. The failure to stop depositing tyres and to make the site secure when required by the authorities emphasises their blatant disregard for the law.
“Criminals who breach our environmental laws in this way can fully expect to be brought to account for their illegal actions.”
This week also saw Arcwood Recycling director Luke Barker jailed for waste offences.
