How to Dispose of Cooking Oil?

Cooking oil is a kitchen staple for many of us, but once it has been used and cooled down, disposing of it can be tricky. Disposal of cooking oil can be risky, with potential dangers including blocked pipes and environmental contamination. Not only can this cause damage to your plumbing system and environment, but also attract pests such as rats and cockroaches. Luckily, you can easily and safely dispose of your cooking oil with minimal harm to the environment.

To Safely Dispose Of Used Cooking Oil

Let’s look at how you can dispose of used vegetable oil so that it would be safe.

To Safely Dispose Of Used Cooking Oil

Mix It With Other Garbage Materials

One of the easiest ways to dispose of your used cooking oil is to mix it with other non-recyclable garbage materials such as food scraps. The oil will act as a sealant to prevent air and moisture from reaching the materials underneath, preventing them from going bad or attracting pests.

Freeze It

If you don’t have much cooking oil left, consider freezing it until your next use. Storing oil in a plastic container or even an ice cube tray can help reduce mess and keep the area clean. If you use this method, make sure to label the container so that no one mistakenly throws away your saved oil!

Try Alternative Cooking Methods

Before throwing out used cooking oil, consider trying different cooking methods that require little or no oil.

Grilling, roasting and baking are all great alternatives to frying in oil. To reduce the amount of oil you use when cooking, consider buying a low-oil deep fryer, an air fryer or stovetop pressure cooker. [1]

Recycle Cooking Oil

Recycle Cooking Oil

Oil can be recycled in a few different ways. Many cities have cooking oil recycling programs that collect used oil and turn it into biodiesel or other renewable fuels. You can also donate used frying oil to local farmers, who use it as feedstock for livestock or fertilizer for crops.


Before you can recycle cooking oil, there are a few important steps to take. Pour the used cooking oil into a heat-resistant container with a tight-fitting lid. Make sure that your container is not too large or too small — an ideal size would be 2 to 3 liters (about 0.5 to 1 gallon). Allow the oil to cool completely before you attempt to store or transport it.

Pick The Right Container

Securely store your cooking oil in a container with a lid. This will help prevent any spills and make it easier to transport the oil when you’re ready to dispose of it. Make sure the container is stable and won’t easily tip over, as this will help avoid any messes or accidents while transporting the oil.

Keep Filling Up Container

Sometimes, disposing of cooking oil can be difficult due to the amount of cooking oil you may have. To make it easier for yourself, filling up a container and keeping an eye on when it’s full is important and will help you reduce the risk of spills or messes from happening when transporting the cooking oil. Make sure to clearly identify the container, so you don’t mistakenly pour cooking oil down your sink while cleaning next time!

Find A Recycling Center

Cooking oil can be recycled and then repurposed for biofuel. To locate a nearby recycling center, start by inquiring with your local waste management agency to learn if they offer oil collection services. If not, you may have to look for an alternative such as taking the oil to a nearby facility that specializes in disposing of cooking oil. [2]

Tips For Reducing The Use Of Cooking Oil

Tips For Reducing The Use Of Cooking Oil

  1. Use a non-stick pan – Non-stick pans provide better heat distribution and require less oil for cooking.
  2. Invest in an air fryer – Air frying is a healthier alternative to deep-frying as it requires no oil at all.
  3. Grill or bake foods instead of frying them – Grilling and baking require very little or no oil, while still providing delicious meals.
  4. Choose a healthier cooking oil – Olive, avocado, and coconut oils are all great alternatives that provide essential health benefits.
  5. Reduce portion sizes – Using less oil for small portions of food can help reduce the amount used in your cooking.
  6. Reuse cooking oil – Depending on the type of oil you use, it can be reused for up to three times before being disposed of. Before reusing, ensure that the oil is still good and has not been contaminated. [3]

Following these simple tips will help reduce your oil consumption and make sure that any used oil is disposed of responsibly. With that in mind, here are some tips for disposing of cooking oil correctly

How Not To Dispose Of Cooking Oil

Cooking oil may seem like a harmless liquid, but it can actually cause serious environmental damage if not disposed of properly. There are several methods of disposal that should be avoided:

Don’t Pour It Down A Home Drain

For the health of your plumbing, it is highly discouraged to pour cooking oil down a kitchen drain – regardless if it’s hot or liquid. Even when it cools off, the grease can congeal into large clumps that are difficult to break apart and cause blockages in the pipes. Not only is it detrimental to the health of your plumbing system, but pouring used cooking oil down the drain can wreak absolute havoc on our environment if it reaches local waterways.

Don’t Pour It Out In The Yard

Instead of discarding used cooking oil, dispose of it properly by pouring it down the drain. However, this is a very bad idea as it can create an unpleasant odor and attract pests. In addition, improperly disposed of oil can seep into soil and end up in waterways, where it has the potential to harm aquatic life. Disposing of cooking oil doesn’t have to be an environmental hazard. Bring your used oil to a nearby recycling center and they will use proficient equipment to turn it into biofuel, thus reducing emissions and making our world cleaner.

Don’t Pour It Down A Storm Drain

Is it safe to pour boiling water down the kitchen sink?

Under no circumstances is it advisable to pour boiling water down the kitchen sink. When hot or warm liquids are poured into a sink drain, they can mix with fats and oils already present in the pipes and create a clog. In addition, if there is standing water in the sink, pouring boiling or very hot liquid can cause it to splash up out of the sink, potentially causing burns.

Cooking oils have no place in the kitchen sink and should be kept far away from it. When fats, oils and grease cool down, they coagulate in your pipes creating blockages that can quickly lead to plumbing complications. Instead of pouring cooking oil down the kitchen sink you should look for alternative methods of disposal such as:

  • Pouring it into a sealable container and disposing of it in the trash.
  • Contact your local wastewater authority or solid waste department to see if they offer collection services for cooking oil.

What if I accidentally pour oil down the drain?

If you accidentally pour oil down the drain, don’t panic. Oil should not be poured down drains because it can clog your pipes and lead to plumbing problems. However, if some oil does slip through, there are a few things you can do to help clean up the mess:

  • Pour hot water into the sink or toilet bowl to help break down any grease that has accumulated in the lines.
  • Use detergent to further break down and dissolve any remaining grease before flushing.
  • Boil a pot of water on the stovetop and slowly pour it into the drain; this will help push out stubborn clogs.
  • If necessary, use an auger or plunger to help break up any large clogs.

Can you compost cooking oil?

Cooking oil, or any type of fats, cannot be added to a compost pile. Fats and oils can disrupt the balance of organisms in the compost, leading to an unpleasant odor as well as attracting pests and animals.
