How often have you poured the remaining cooking oil from the pan down the drain? That's something I'm sure we've all done at some point. Cooking with a firm understanding of the proper amount of oil can be tedious most of the time.  Find below how to dispose of cooking oil!

There are so many other things to handle when cooking that you often forget or mistakenly add a little more oil in the pan than is necessary.  

If you've been considering how to properly dispose of your cooking oil while reducing waste, here are a few simple actions to take. 

How To Dispose Of Cooking Oil: Tips

Cooking oil disposal is critical for a variety of reasons. The more you drip the residual oil from your sink's drains, the more clogged and unclean your drains will become.  

How to Dispose of Cooking Oil

However, you may dispose of cooking oil more effectively using the following methods: 

  • Keep it in a secure location in a storage container. Make sure you have a jar or a bottle set aside for collecting all the leftover oils every time you cook.  

This way, if you use the pan and it has residual oil, you won't have to worry about finding a location to dispose of it.  

When you're cooking, you're usually in a hurry, and you can't go looking for a new container to decide where to toss it. If you have a container on hand, dripping the excess oil into it will be a breeze. 

  • If you live near a restaurant, you can inquire if you can give your surplus oil to the eatery. Restaurants have bulk disposal options for oil and other materials. They may be able to assist you in this situation.
  • You can always toss any leftover vegetable oil into the compost pile. Vegetable oils are made from plant sources such as soy, coconut, olive and others, so there is a low risk of spoilage.  

Oils containing animal fat should not be disposed of in the compost since they may attract a variety of insects and bugs, causing you further inconvenience. 

  • For your home, you can always engage a hazardous waste disposal service. Home hazardous trash collection is handled by a variety of agencies. All you have to do is gather all of the wasted oil in a container and deliver it back on a regular basis. 
  • It is critical to separate your waste, and you can do so by creating a separate trash can with a waterproof bag from the inside to carry the oil. This way, whenever you throw trash out, you'll be aware of the oil-filled bin. After that, you can dispose of it separately without staining anything else. 
  • If you don't want to deal with the viscous liquid cooking oil waste, you may always freeze it and keep it in solid form without the worry of leakage. 

These are a few of the most practical ways to dispose of used cooking oil. One thing to keep in mind is that, because it's oil, it can't be treated like water, you'll need to be extremely careful where you dispose of it.  

If not done correctly, it can result in serious dangers. When you dispose of oil recklessly, you risk making the floor slippery, which can cause problems of its own. 

Reuse Cooking Oil

If you do not like the thought of pouring the used cooking oil in the trash container or sink as waste, then you can think of ways to reuse it. Here are a few tips to do so: 

  • The safe storage of spent oil is necessary. You can divide the oils according to what you're cooking. For example, if you've cooked some fish, set aside a container solely for the oil from the fish.  

In this manner, you can cook another batch of fish in the same oil the next day without the danger of transmitting the smell of one food item to another. 

  • Use a strainer every time you store your excess cooking oil. By doing so, you will be able to segregate all the impurities that may create problems if you plan to cook in the same oil the next day. 
  • Keep a pan with oil just for frying your chips and fries. This way, you will not have to take out a new pan every time you feel like frying some chips. Just cover the pan with a lid and you can use the same oil for a couple of days to fry your favorite snacks easily.  

Reusing is always the best idea to curb down the waste of anything. However, always make sure that the oil that you plan to reuse has not expired yet.

One of the best ways to reduce the wastage of cooking oil is to reduce the amount that you use while cooking. Here are a few ways in which you can reduce the use of cooking oil drastically: 

  • Use an air fryer to reduce the usage of oil. 
  • Use a non-stick pan to cook in less oil. 
  • Use oil with calculation. Do not pour it directly from the bottle, use a spoon instead. 
  • Use napkins to soak extra oil from the food. 

Using less oil is always a good idea, and limiting oil waste not only keeps your home clean, but also keeps the environment clean. Griddle pans and air fryers are examples of cookware that use less oil.
