Fried foods are enjoyed by quite a lot of people. However, when food is fried, there’s usually a leftover of oil. Not many people know what to do with this, whether to properly dispose of it, reuse it for frying, or anything more. 

Most people would usually pour it down the kitchen drain, but that’s not the ideal thing to do. Yes, you read right. Don’t pour your oil down the drain. This article will teach you why this is not right, and the best way to dispose of your cooking oil. Read on to discover more. 

Why can’t I pour my oil down the drain?

As you might have guessed, The answer to this has to do with clogging. When you pour oil down your kitchen pipe, it doesn’t stay liquid forever. As the temperature becomes lower and it cools down, it’ll become solid, which would build up over time and clog your pipes. Unfortunately, the solution to clogging won’t be as simple as buying a new pipe, as clogging can lead to flooding. So the next time you want to dispose of oil, tell yourself, “Definitely not down the drain!”

How else am I supposed to dispose of my oil?

A much safer alternative would be to wait for your oil to cool down after frying, transfer into a metal container, and voila! Then, you can easily throw that in the trash.

No metal accessible?

In place of metal, you can use an empty can of soda, plastic bottle, or bag.

Eco-friendly ways of disposing of your oil

If you have compost in your garden or backyard, you can pour the oil used to fry vegetables. You can also transfer your leftover oil to a large container and seal it off. When the container is filled with oil, you can take it to a recycling center to convert it to better, e.g., biodiesel.

How to reuse frying oil
