How to Dispose of Cooking Oil after Frying

Deep-frying food is fun and fried foods are yummy. But let’s face it, degraded frying oil is not easy to deal with. Not unless you live in a place where you can easily dispose it off in an environmentally safe manner. But how many of us live in such places?

Used up cooking oil is unlike other liquid waste. You cannot just pour it down the drain. It will clog the pipes or leave sticky residue inside. The residue later combines with food particles and other waste to clog the pipes. The end result is stinky mess that calls for a snake in the drain. Even worse, you might introduce problems into the entire sewer system of your residential area.

It is also not the kind of waste you pour in an open place. Unless you have little concern for the surroundings.

So, how do you dispose of cooking oil safely and properly after frying?

  • Drain the oil from the pan into a plastic bottle (sealable) or container with a tight lid. Ensure that the container/bottle is made of good quality material. Low quality plastics can break easily and create unnecessary mess through spillage.

  • Transfer completely cool oil into a thick polythene bag and tie a tight knot to prevent leakage. Store the bag in the freezer and wait until the garbage collection to throw it away with the rest of your kitchen wastes.
  • Alternatively, mix the oil with solid matter such as flour and saw dust in a firm polythene and dispose into the garbage.

Reuse Oil

You can recycle oil at home by reusing it severally. In most cases, deep frying oil begins to change in color after several uses. The only way it can degrade faster is if food is left to burn in the process of deep-frying.

Therefore, it is important to let oil reach the appropriate temperature before frying foods. Timeliness is also critical when frying and removing food from the oil.

  • To preserve oil for reusing, remove it from heat and let cool completely.
  • As it cools down, food particles will settle at the bottom of the pan.
  • Decant or gradually pour the oil into another container so that the food particles can be left at the bottom of the pan.
  • Use a coffee filter or cheese cloth to filter food particles from the remaining oil.
  • Transfer your oil into a sealable container and store in a cool dry place. However, you can keep it in the freezer if you intend to wait for a long time before reusing it.

Important note: Reuse oil to cook the same type of food. If not, it will transfer the flavor of the food you cooked the first time to other dishes.
