The convictions relate to a series of fly tipping incidents which took place across three fields near the St Mellons Business Park, some of which form part of a designated Site of Special Scientific Interest (SSSI).
The offences came to light in 2021 when NRW began investigating the unlawful disposal of mixed household, construction and green waste on private farmland.
The case was heard by Newport Crown Court, where both defendants pleaded guilty to the offences under environmental legislation.
Kyle Mason, 46, was sentenced on 1 August 2025 to 14 weeks’ imprisonment, suspended for 12 months. He was also ordered to pay £200 in costs to NRW and an undisclosed victim surcharge.
John Janes, 52, was sentenced at an earlier hearing on 2 May 2025, receiving a £500 fine, £750 in costs to NRW, and a £200 victim surcharge.
NRW’s investigation revealed that multiple van loads of waste had been deposited across land owned by three separate landowners.
Evidence found at the scene linked the fly-tipping to both men and to businesses associated with the defendants.
John Rock, Operations Manager for NRW, said: “Waste illegally deposited can have a devastating impact on farming businesses and rural communities.
“The waste can be extremely costly and time-consuming to remove and can be harmful to wildlife and livestock.”
Further evidence came in June 2022, when surveillance footage captured by Liberton Investigations showed a transit flatbed vehicle entering one of the fields loaded with waste and leaving empty shortly afterwards.
Both men were interviewed during the investigation and initially denied involvement.
However, they later pleaded guilty in court. Mason pleaded guilty to dumping five van loads of waste, while Janes pleaded guilty to depositing a bag of household waste.
Rock added: “The joint working with Gwent Police on this case has been hugely beneficial and we’d also like to thank the Cardiff residents who provided supporting evidence for this case.”
