How To Dispose Of Cooking Oil Correctly

How To Dispose Of Cooking Oil Correctly

Pouring leftover cooking oil down the drain after preparing fried chicken, stir-fry, or bacon and eggs may appear to be the quickest and easiest option. However, this is the worst thing you can do since grease may clog kitchen drains and municipal sewage systems. You should avoid both of these scenarios. Let’s discuss how to dispose of cooking oil correctly.

So, to assist you with appropriate disposal, we’ve listed the measures you can take at home to dispose of old cooking oil in a safe, effective, and environmentally responsible manner. We’ve also included some inventive ideas for using leftover cooking oil into compost and the production of other useful things such as soap.

Remember that even a tiny quantity of grease poured down the drain every day may have a cumulative and potentially detrimental effect on your house and the environment.

Simple Steps Regarding How To Dispose Of Cooking Oil

1. Properly store and then dispose of with other household garbage

Most homes do this since it is typically permissible to store leftover cooking oil and subsequently dispose of it with the rest of the household waste. However, there are certain procedures to take and considerations to make.
First, ensure that the spent oil is cold enough to be poured into another container designated for disposal.
Once it has cooled sufficiently, store it in sealable, disposable containers such as plastic bottles, take-out boxes, or empty milk cartons.
Properly and firmly seal the containers.
After it has been firmly packed, place it in your food waste container for disposal.
Additional Hints: If you want to deal with leftover cooking oil as a “solid” rather of a “liquid,” you may freeze it. It takes roughly a day for used cooking oil to totally freeze.
When attempting to combine leftover cooking oil with other household garbage, do not use plastic bags to keep it. Plastic bags are not strong enough, and spent oil may seep out of them.

Also, here’s an intriguing tidbit about frying oil:

Did you know that you may freeze cooking oil to keep it fresh? Fresh, unused, or unopened cooking oil can survive up to 2 years in the freezer and around 1 year in the pantry if it is well packed.

 

2. Return used oil to restaurants for proper disposal.

Do you have any restaurant-owning friends? Or maybe you live near a restaurant. The presence of a restaurant aids in the disposal of cooking oil since they will have sources for hazardous waste disposal, allowing you to rest confident that the waste is being disposed of appropriately.

 

3. Get in touch with a domestic hazardous waste removal provider.

This is a multi-beneficial alternative since firms who collect home hazardous waste (HHW) frequently collect other types of trash, such as medical waste. If they provide a doorstep pick-up service, you will be able to dispose of various sorts of hazardous trash at once.

 

4. Make use of a Grease Disposal System

This is a grease disposal system kit in the form of a system kit. This method consists of a plastic container with foil-lined bags that can store up to 32 ounces (2 lbs). There are several choices available, such as this The Fat Trapper Grease Disposal System provided by Bed, Bath & Beyond.

Simply place a bag in the container and fill it with used/COLD cooking oil. When the bag is filled, seal it and toss it in the garbage.

 

5. Place in the compost

This may come as a surprise given that it is oil, right? If you use 100 percent vegetable cooking oil, it is simply derived from foods such as:

  • Soy
  • Corn
  • Sunflower
  • Grape-seed
  • Olives
  • Coconut

Because they are all-natural foods, they are completely acceptable to put to your usual compost pile. The only exception is if you used animal grease or cooked with meat, as this may attract undesirable pests and small animals. Earthworms like consuming cooking oil, which is a fun fact. When you add cooking oil to your compost pile, you are helping both the oil and the creepy crawlers beneath. However, there is one caveat: Try to use as little frying oil as possible. One explanation is that it may attract more animals than just worms. Another concern is that it may result in an accumulation of grease that obstructs air/water movement. The fancy phrase is “hydrophobic barriers” if you want to impress your friends and relatives.

 

6. Combine with other types of solid waste

Before disposing of leftover cooking oil, you can mix it with other absorbent waste items to “convert” it to solid trash. You may then just keep it as normal and include it in your regular home garbage disposal.

  • Sawdust
  • Sand
  • Flour
  • Cat litter

It is clear that this technique aids in the rapid absorption of fluids.

This simplifies the issue while also benefiting city sanitation personnel. You might choose to reuse or recycle cooking oil to have a greater influence on the environment. The next section delves deeper into these possibilities.

Here Are Some Great Tips For Reusing Cooking Oil

 

1. Keep in glass jars

 

This is an oldie-but-goodie method for storing leftover cooking oil before utilizing it in another recipe. Another advantage of this method is that it allows you to repurpose old jars.

What you must do is as follows:

When you’re through frying, simply leave the leftover cooking oil in the flying pan to cool.
When it’s cold enough to handle, carefully transfer it to a glass container.
Tightly close the container.
Make careful to keep leftover cooking oil separately depending on the sort of food you used it with. For example, do not combine used cooking oil from fried chicken with used cooking oil from stir-fry fish. Common sense tells us that these flavors will not go well together.
After that, you may keep the glass jar safely in your pantry or kitchen shelf.
Storing leftover cooking oil in glass jars is one efficient technique to postpone the disposal/recycling of the grease. Of course, you won’t be able to reuse it an infinite number of times. However, depending on the type of food you’re cooking (meat/veggies), the amount of food you’re cooking, and the cooking temperatures, you can usually get 2 to 6 (tops) re-uses from the cooking oil.

 

Extra Suggestion For Storing Cooking Oil To Reuse:

 

One typical kitchen tip for getting the most out of your leftover cooking oil and keeping it free of “impurities” is to lay a tiny strainer or piece of coarse cloth on the lip of the glass jar as you pour it. This helps you to efficiently strain any leftover batter or other food.

If you’re using a strainer, make sure to wipe out any leftover oil before washing it in the sink to avoid having even minor quantities of grease fall down the drain.

It may be intuitive for us to use paper towels to wipe oil off strainers, dishes, pots and pans, and then toss the old, greasy paper towels into the recycling bin because – well, paper towels are typically recyclable, right?

But wait a minute.

Grease-lined paper towels are typically not accepted by recycling facilities. It’s preferable to use more eco-friendly options, such as a wash cloth made from an old t-shirt or a microfiber cleaning cloth, which can quickly rinse, wash, dry, and remove oil while reducing non-recyclable waste.

 

2. When recycling cooking oil, keep an eye out for the “expiration date.”

 

The cardinal rule of reusing cooking oil is to recognize the telltale indications of poor cooking oil. This is based on a variety of indicators, including the oil’s look, texture, and fragrance. Here are some broad pointers from experts:

  • If you do decide to reuse cooking oil, keep cooking oil used to fry fish or other seafood separate from cooking oil used to fry chicken, pig, or beef. It’s also a good idea to mark jars so you know what kind of food the cooking oil has been cooked with.
  • Cooking oil from fried chicken can only be stored and reused three to four times. According to tests, following the fourth reuse of leftover fried chicken cooking oil, it developed a murky, green tint.
  • Cooking oil derived from potato chips is typically “cleaner,” which means it may be reused up to eight times.

Based on the information above, here is a short set of questions to ask yourself: Are you reusing cooking oil from a breaded or battered dish? It is safe to reuse up to three or four times. Are you utilizing cleaner or clearer frying oil from potato chips or french fries? It is safe to reuse up to 8 times. This may be utilized for a much longer period of time if it is additionally refilled or mixed with new, fresh oil.

 

3. Produce biodiesel from soybean oil.

 

Is it possible to start a diesel engine using soybean oil? It turns out that this is a possibility. Consider that corn is still being utilized for that purpose today.

One caveat: you’ll need more than the amount of cooking oil needed to fry one egg. You’ll actually need a lot of it. In fact, certain sectors, such as restaurants, have built a business out of it. They sell large quantities of cooking oil to firms that turn it into biodiesel.

There are several internet tools for locating local firms that turn cooking oil into biodiesel. If they only take large sums, look for a nearby restaurant that follows the same policy. Perhaps you could give your own cooking oil.

 

4. Create soap.

 

This is perhaps the last thing most people would think of doing with leftover cooking oil. Soap is typically made from fat. Thus, using cooking oil to create soap is convenient since it is another way to reuse the oil other than cooking with it again.

It’s also far superior to simply dumping the oil into the rubbish pail. That is the polar opposite of the three Rs and is unquestionably less eco-friendly.

 

5. Recycle cooking oil to make a non-toxic pesticide or weed killer.

 

While insects and tiny animals adore cooking oil, it may also be used to keep pests at bay. The oil efficiently suffocates dangerous bugs by coating their bodies and blocking the pores through which they breathe. Aside from that, because it is made entirely of vegetable oil, it is also an environmentally beneficial alternative.

Here’s how to manufacture pesticide from frying oil:

  • In any container that can be closed with a lid, combine 1 cup of old vegetable oil and 1 tablespoon of soap.
  • Cover it firmly and vigorously shake it.

When you’re ready to utilize your homemade cooking oil pesticide spray combination, follow these steps:

  • In a generic spray bottle, combine 2 tablespoons of oil spray mix with 1 litre of water.
  • Spray immediately on pest-infested plants’ surfaces.

Vegetable oil may also be used as a weed killer. Use it in the same way as you would a pesticide. If you prefer recycling leftover cooking oil to reusing it, the next section will provide you with some basic information.

How To Recycle Cooking Oil

How To Recycle Cooking Oil

 

Step 1: Preparation For Used Cooking Oil Recycling

 

Consider if you like liquid or solid used cooking oil form.

Some people prefer to deal with solid garbage rather than liquid waste. If this is the case, simply allow the oil to cool and it will solidify into a block of frozen grease. If you want it to be super-solid, freeze the cooking oil once it cools down to help it solidify even more. One of the primary advantages of freezing cooking oil is that it is easier to handle. This includes whether you want to reuse it shortly or dispose of it.

If you don’t mind storing spent cooking oil in its liquid form, do what we recommended in the first part of this article: cool the cooking oil, move it to a plastic container with a tightly-closed lid, and then place it in your food waste bin for appropriate disposal.

 

Step 2: Select the appropriate container

 

You may recycle plastic butter containers or coffee cans, for example. Make sure the container is labeled so that no one mistakes cooking oil with ground coffee beans.

The oil does not need to be refrigerated. The only exception is if you intend to utilize it in the future.

 

Step 3: Continue to fill your container.

 

This is particularly true if you simply use a small amount of frying oil. By filling it up as required, you can make the most of the container you’re using while also saving time by dumping off all of your old cooking oil at once.

You don’t have to be concerned about different types of cooking oil becoming mixed up in the same disposal container you’re using because, in this situation, it’s believed that they have already been utilized to their maximum capacity and are ready to be dropped off at the recycling center.

However, any big chunks of meat or vegetables should be removed.

 

Step 4: Locate a recycling center.

 

Used cooking oil is sometimes accepted as home hazardous waste by recycling facilities (HHW). They may only accept cooking oil during the Christmas season in some cases. If this is the case, you might seek for other disposal options. Check with your local department of public works first to see if there are any free programs available. You may just Google it or phone the relevant municipal or state government to see whether such programs are available. After that, all you have to do is drop off the frying oil. They’ll do the remainder of the labor, allowing others to utilize the cooking oil to make some delicious fried chicken or shrimp tempura. You may also utilize the following web-based tools to find recycling organizations that will gladly accept your used cooking oil:

Another option is to call the local fire department. They will take leftover cooking oil for recycling in some cases. This not only helps you get rid of the cooking oil, but it also assists your local fire department. Recycling cooking oil offers several advantages, including:

It’s an efficient technique to convert a common home waste item into clean biodiesel, which can be used to fuel most diesel engines.

It prevents greasy oil from being poured down the drain, which can clog/damage pipes and sewage systems.

Restaurant owners and other companies may profit by selling a big quantity of leftover cooking oil to commercial oil recyclers.

 

Avoiding Mistakes When Disposing of Used Cooking Oil

 

Do not pour down the drain.

  • It’s just as essential to know how NOT to dispose of cooking oil as it is to know how to. There is no doubt that used cooking oil is filthy. This is especially true if you’ve been deep-frying food, since lard or vegetable shortening may have been used in the process, making the oil much more hazardous.

Do not pour – even in tiny amounts – down the sink.

 

  • This may appear to be a simple procedure, but it is also extremely dangerous. Even a small amount of frying oil might clog the kitchen/sewage pipes. If this occurs, you will need to contact a plumber for repairs, which may be extremely costly. If the sewage lines get clogged, spilling sewage might cause damage to neighboring basements.

Do not flush down the toilet.

  • Putting leftover cooking oil down the toilet can result in many of the same issues as pouring it down the sink. This includes bathroom and sewage lines, among other things.
    One of the major issues is based on basic physics principles: oil and water do not mix. Aside from that, the drain line walls will be harmed. Another consideration is that oil travels more slowly than water. As a result, it will combine with other substances and block the whole pipe system. The issue is exacerbated when old cooking oil is used instead of new cooking oil. When oil is utilized, things like animal fat aggravate the problem and increase the likelihood of clogged pipes/sewage.

Pouring heated oil into a trash can or garbage can is not a good idea.

 

  • This can attract a variety of pests, including bugs and rodents. It can also cause problems with garbage trucks and solid waste disposal facilities.

Don’t put anything into the septic system.

 

  • The reason for this is that it can block pipes and even disrupt the drainage field and distribution lines. There’s even a risk it’ll poison nearby rivers.

As helpful as it is to properly dispose of, reuse, and recycle leftover cooking oil, what works best is to limit its usage in the first place. Continue reading to learn about some practical strategies to minimize your usage of cooking oil in the next section.

 

Tips for Cutting Down on Cooking Oil

 

One method to cross used cooking oil disposal off your must-do list at home is to cook with less of it. Not only is “oil-less” cooking healthier in general, but it also results in more tasty, innovative recipes.

Here are some kitchen techniques to help you reduce your usage of cooking oil:

  • Make use of an air fryer.

An air fryer is a fantastic alternative to traditional frying since it is designed to imitate cooking. It works by circulating hot air at high speeds, which browns or crisps the food within.

  • Bake.

While it may appear to be more time-consuming than frying, baking is a healthier option. There are several foods that may be baked rather than fried, including potato croquettes, samosas, fritters, kebabs, and patties. These (and others) taste wonderful, warm, and soft when baked.

  • Steam or pre-cook the vegetables.

Have you ever tried steaming fish? Or how about steamed chicken breasts? It tastes wonderful when seasoned with garlic, pepper, salt, and copious amounts of butter! Combine it with some cooked potatoes and carrots for a quick and healthy meal. Pre-cooking before frying also cuts down on the amount of oil required.

  • Make use of a shallow frying pan.

Instead of deep frying, use a small frying pan with a cover to use less oil. It also retains moisture, allowing food to cook faster and taste better.
