Throwing the oil waste to the soil or the basin is a really bad habit that not only create blockages like this  if not it contaminates the sea water and  harms the sea wild life

Here for you some ideas on how you could recycle your used home oils while doing some DIY :

 1- You should reuse used oil as much as possible. Cool the oil, strain it through cheesecloth to get rid of food bits, and store in a glass jar (or the original container) in a dark cupboard.

There is no limit to the number of times you can reuse old cooking oil, but you should watch for signs of degradation, such as a murky appearance, foam, or an odor that’s off.

When is ready to go, check with your council for a way to dispose it or put in a sealed container outside the bin.
