Which bin should it go in?
Black bin or purple sacks.
Buy a new bin
If you don't have one you can buy a new black bin or purple sacks online .
You can get rid of small amounts of cooking oil, fats, plate scrapings of fatty food and surplus oil from pans and trays with your food waste.
Larger amounts should be put into a sealed container in your black bin. You should never pour cooking oil down the sink as it can block it.
