Reviewed by [**Rambo S** ](/editorial/), Wrong fuel expert, Fuel Fixer · last checked 1 November 2026 ## About red diesel disposal in Dowlais Merthyr Tydfil The problem people bring us with red diesel is usually legal as much as practical: stranded stock after the entitlement changes, a tank that needs to be dye-free before reuse, or fuel from a business that has closed. The 2022 change is the reason for a lot of these calls. Sectors that lost the entitlement — construction, plant hire, many commercial users — were left with red diesel they could no longer put in a machine, and the compliant answer is removal and documented disposal. Once lifted, the red diesel is disposed of through a licensed route — recovered where it can be, destroyed where it cannot — and every step is captured on the waste transfer note you keep. Getting disposal right is about the destination and the record. The fuel from Dowlais Merthyr Tydfil goes to a permitted facility, is handled under environmental rules, and the transfer note is your audit trail showing it was dealt with lawfully. ## Local Welsh red diesel disposal in Dowlais Merthyr Tydfil: the facts Fuel | Red diesel | Service | Collection and licensed disposal | Council area | Merthyr Tydfil | Postcode districts | CF47, CF48 | Why it degrades | Ages like diesel, plus a legal marker dye that stains tanks | Typical sources | Farms, plant, generators, bowsers, decommissioned tanks, closing businesses | 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 red diesel comes from around Dowlais Merthyr Tydfil The red diesel we collect and dispose of in and around Dowlais Merthyr Tydfil tends to come from sold or dispersed farms, closing depots and yards, and decommissioned bulk tanks holding rebated fuel.
