Disposing of out of date cooking oil

[3littlefrogs]

What is the correct way of doing this?
I am sure it shouldn't go down the drains.
(I have been clearing out elderly person's property and found 2 biggish containers of cooking oil).

TIA

Pour it in to an old bottle and bin it.

Yep or line a pan with a couple of carrier bags, pour it in, tie it and bin it.

tip it on the compost heap or a quiet corner of the garden. No need for landfill.

Our local tip has a big container for it.
