About old diesel disposal in Porthmadog

The issue with aged diesel is what grows in it and what settles out of it. Microbial contamination at the water line, oxidation products, and waxing in cold weather all leave a fuel that fouls the fine tolerances of a modern injection system.

Bulk and bowser volumes are routine. Whether it is a few hundred litres in a standby generator or a few thousand in a farm tank, the collection is booked against the volume and the access rather than turned away for size.

Disposal closes the loop: the collected diesel reaches a permitted facility, is processed or destroyed lawfully, and the transfer note issued on site is your proof it was done right.

For disposal, the licensed route and the documentation are the job. Fuel collected in Porthmadog is taken to a permitted facility, recovered or destroyed, and logged on a transfer note you keep as compliance evidence.

Common questions

Do you dispose of old diesel in Porthmadog?

Yes — across Porthmadog and the rest of Gwynedd. A registered carrier attends home, farm, depot, marina and commercial sites, pumps out the old diesel and issues a waste transfer note on site.

Can contaminated diesel be cleaned instead of removed?

Polishing can recover lightly contaminated diesel, but heavily bugged or watered fuel is usually removed and the tank cleaned. We can advise once we know the state of it.

Will you empty a farm or bulk tank?

Yes — domestic, farm, estate and commercial bulk tanks, bowsers and drums. Give us the volume in litres and the access and you get a price and a slot before we travel.

Do you clean the tank as well?

We remove the fuel and can arrange a tank clean where the bug or sludge means the vessel needs it before reuse. Tell us the condition when you call.

How quickly can old diesel be collected?

Often the same day for accessible sites, otherwise a booked slot. The quote and window are confirmed before anyone travels.
