Land owners should beware of illegal tyres dumping scams which appear to be escalating in the wake of new recycling laws.
Conmen are collecting old tyres from garages for a small fee, then storing them on private property and leaving the land owners with huge clean-up bills, according to an investigation for the BBC Wales programme Taro 9 last night.
The scam has been gathering momentum since a recent EU directive which states that tyres can no longer be disposed of in landfill sites.
This means garages are responsible for paying a reputable recycling company to take them away and dispose of them legally.
But often the scams are so elaborate that the conmen produce recycling company credentials to convince landowners to let them store the tyres on their property.
Then the bogus tyre collectors do a moonlight flit, leaving the landlords to foot the bill for disposing of the tyres.
It is estimated that it costs local authorities in the UK around £1.65m a year to clear illegally disposed tyres. But if they have been abandoned on private property it is the land owner that has to foot the bill.
In the case of one farmer highlighted by the news report, the bill amounted to a staggering £20,000!
