Sounds like the care home was in on it too
I think MacDs advertise that they reuse their cooking oil, after something is done to it, to use in their vans and lorries. I believe there is money in collecting used cooking oil I suppose he was being clever to try and start up a business in it
How can you pick up cooking oil without permission ?? Break into the kitchen at night time ???
If you've ever heard of bio fuel, it has an element of re-cycled cooking oil in it.
I used to run Isuzu Trooper 4x4s on fresh cooking oil which was tax free. It was cheaper than diesel before the Ukraine war but the price went up quite significantly then. The market for recycled oil increased but it became impractical to mess about with the filtering at home, but on an industrial scale it's still very economical.
McDonald's recycle their oil and the majority of their truck fleet run on it now. If you watch a delivery at a McD's you'll see that at the end of it, the entire deep fat fryer unit is loaded back into the truck as a sealed unit for return to the depot and re-cycling of the contents.
