For years, when I changed the oil in my deep fat fryer, I would leave the old oil by the side of the other bins in their 2.5 litre plastic bottles, the then suddenly decided they would no longer take it , telling me to take it to the tip (nearest is 6 miles away) which in do use, but resented being told they would no longer take what is household waste in my eyes, so they still get to take it, but I now conceal it under rubbish In the black bin,
All this, when our local water company are complaining of sewer problems caused by people putting far and oil down their drains, which I would not do.
