How Do You Properly Dispose of Grease And Cooking Oil?

We all have some left-over grease from our occasional binge, but as most cooking enthusiasts would know, grease can create a huge mess in your kitchen. Grease is probably the most difficult food item to dispose of in the kitchen. While thinking of how to properly dispose of grease and cooking oil, almost all of us have at least considered pouring it down the drain and forgetting about it. But that actually has a lot of nasty repercussions.

Can You Pour Grease or Cooking Oil Down The Drain?

Never!!! The general consensus is that you should never pour down the grease or cooking oil into drains unless you have a plumber on speed dial. Grease contains fat compounds, which can solidify in your drain and clog them up completely. There have been incidents where the clogged drainage pipes have resulted in people’s basements completely filling with sewage- a less than amiable experience, of course.

Now, you may be curious as to how restaurants get rid of the massive amounts of grease that are generated in their kitchens on a daily basis. Usually, restaurants have a whole system of equipment installed in their plumbing system that catches the grease from the oil that has been washed down the sink. While this may sound like the best way to dispose of grease, it is quite expensive.

So, how do you get rid of grease and cooking oil in your own kitchens then?

How to Dispose of Cooking Oil and Grease Properly?

Here we will discuss some safest ways to dispose of used cooking oil and grease-

1. Empty Them Into The Trash

The proper way to get rid of oil and grease is in the trashcan. Here is how you should do it:

  • Allow the grease to cool down and solidify in the utensils.
  • Once solid, scrape it off the pots and pans and collect in in containers which you can throw away easily.
  • Once the containers are full, you can throw them in the trash can. Remember to put the containers into a bag made of plastic first- in case the grease melts and leaks from the heat.

If you do get grease down the drain, there are certain tricks you can try to prevent the pipes from clogging.

Use Vinegar and Baking Soda – Pour baking soda and white vinegar down the drain to dissolve some grease from there. Then, use a plunger to dislodge the collected grease from the pipe. However, if none of these work, you will need to call the plumber.

 Let it solidify – For cooking oil and fats that solidify over time, it is best to let them do so. You can chill the grease in the refrigerator for it to harden up, and then carry on with your cooking grease disposal in the garbage.

2. You Can Also Reuse Your Cooking Grease After Filtering It

This process involves taking out bits and chunks of food from the grease that has been left in the pan and then using it to cook food again. We suggest that you use a cloth like muslin or a cheesecloth strainer for this process. These are a better option than kitchen towels, as they can be washed and used time and again.

To reduce the production of grease, it is best to use cooking oils that are not as fatty. Use just a little bit of cooking oil – just enough to prevent the food from sticking to the pan. Not only does this reduce greasy messes in your kitchen, but it also contributes to your healthy and active lifestyle.

3. Eco-Friendly Disposal

There is also a really Eco friendly way to dispose of vegetable oil. Vegetable oil can actually make great food for earthworms. So, adding them to your compost is a great way of disposing of cooking oil in the garden. However, you have to be careful with this technique, since too much cooking oil in your compost can actually attract vermin to it, and create barriers between the water and air flow to the roots.
