It sinks below the fuel, and at that boundary the bug takes hold, throwing dark strings and slime that choke filters within minutes of the pump drawing them up. Removing the fuel and cleaning the tank is the cure. Whether old diesel can be saved depends on how far gone it is. Lightly contaminated fuel can sometimes be polished — filtered and dewatered — but water-laden, bugged or long-standing diesel is normally removed and the tank cleaned. Disposal is about where the diesel ends up and being able to prove it. Once collected it goes to a permitted facility for recovery or destruction, and you get a waste transfer note recording what left, when and where it went — your duty-of-care evidence if anyone ever asks. Disposal closes the duty-of-care loop for a site in Thornhill Cwmbran: permitted facility, lawful handling, and a transfer note that answers the only question that matters if anyone asks — where did it go and can you show it. ## Local Welsh old diesel disposal in Thornhill Cwmbran: the facts Fuel | Old diesel | Service | Collection and licensed disposal | Council area | Torfaen | Postcode districts | NP44 | Why it degrades | Oxidises, drops sediment and grows diesel bug where water is present | Typical sources | Farm tanks, generators, plant, HGVs, boats, bowsers, bulk stores | Classification | Hazardous waste — waste transfer note issued | Regulator | Natural Resources Wales | Typical cost | Quoted per litre or per job | Attendance | Collected and disposed of under licence | Helpline | 01295 380724 | ## Where old diesel comes from around Thornhill Cwmbran Most of the old diesel we collect and dispose of near Thornhill Cwmbran originates in farm and estate bulk tanks, standby generators and plant stood between jobs with fuel in the tank.
