how to dispose of cooking oil

icture this - you are in the kitchen and have just finished cooking up a delicious meal. You begin the cleaning up process and it is time to dispose of the cooking oil. You stand there with the frying pan in hand and think to yourself ‘I will just pour the oil down the kitchen sink, what harm can it do?'. 

Before you pour used cooking oil down your drain, consider the impact it will have on your pipes

Your drainage plumbing is made up of various pipes and channels in and outside of your property that all lead to your sewer drains and stormwater drain. This eventually ends up in the treatment plant of your city. 

It is crucial to monitor what goes down your kitchen, bathroom, laundry, and toilet drain. 

Is It Bad To Throw Cooking Oil Down The Drain?

The only liquids that should be washed down our drains are water, toilet paper, and human waste. Food, disposable or wet wipes and other foreign objects can block the pipework and harsh chemicals can affect the pipes through corrosion or creating cracks. 

Household cooking oil such as olive oil and other grease and fats will end up cooling down as the temperature drops inside the pipework and solidifying. This hardened grease will eventually create a barrier inside the pipe wall. Other materials will then catch onto the used oil. This is not good for the smooth flow of water and can often be the cause of smelly drains and blockages. 

So if you shouldn't dispose of used cooking oil down the drain, what is the safest method of disposal? Here are some helpful tips and suggestions.

How Should You Dispose Of Cooking Oil At Home?

There are other alternatives to disposing of cooking oils down the sink:

  1. If you have a small amount of grease leftover in the pan, wipe it down with an absorbent paper towel and then throw it in your garbage bin bag.

  2. You can recycle your cooking oil and fats. Once you have finished using it, filter it and place it in a container or jar and leave it in the fridge to reuse. You may also freeze it to make it last longer. 

  3. For larger amounts of oil, pour it into a sealable, non-recyclable container and toss it in the bin. 

  4. If you are going to reuse your cooking oil, just make sure that it is filtered. Remember to be mindful of other people's dietary requirements. If a guest is a vegetarian, then avoid using the fat you have cooked animal products in. 

Can You Dispose Of Cooking Oil In The Garden?

You can recycle cooking grease in your garden. You can mix it into your compost system but remember to use small amounts. It is best to use vegetable-based cooking fat, such as olive oil or sunflower oil. 

Vegetable oils are considered organic and can be mixed with birdseed. 

Taking Care Of Your Drainage System

Cooking oil disposal should be a part of our cleaning routine. It may be easier to dump oils and scraps down the sink but remember, fats and grease that are cooled down, will become lodged inside the pipework

Food and other organic material and waste can create a smelly environment for your kitchen, so remember to place old oil for deep frying into garbage bags and dispose of in your garbage, or if you would like to reuse your oil, simply pour into a sealed container and keep it stored it in the fridge or freezer to use at a later time. 

There are many ways you can save your plumbing and ensure your pipework is working at its best. Dispose of your old cooking oils correctly and not down the pipes.
