Is mixed fuel contaminated with water hazardous waste?

In brief

Yes. Fuel with water in it is still hazardous waste, and the water separated from it usually is too, because it carries dissolved and suspended fuel. Discarded mixed fuel is coded 13 07 03*. Call 07950 582635 or send an enquiry.

What that means for mixed fuel contaminated with water

It must be stored safely, described accurately, moved by a registered waste carrier on a consignment note and taken to a facility permitted to accept it.

Can mixed fuel contaminated with water still be recovered?

Usually yes. Free water settles and is drawn off, and the fuel above it normally keeps most of its value once filtered.
