If you have some leftovers of olive oil, or the olive oil has expired, you’re probably thinking of disposing of it. While I always suggest using olive oil for other purposes instead of disposing of it, here are a couple of ways I use to dispose of olive oil.
Why Dispose of Olive Oil
Like all oils, olive oil does not dissolve in water; it stays in suspension, creating an emulsion. When this emulsion is flushed out, the fat particles stick to the pipe walls. Over time, the pipes develop a lot of grease, and greasy pipes are prone to blockages and might result in challenging plumbing issues.
How To Dispose of Used Extra Virgin Olive Oil
Olive oil can be disposed of in a variety of ways. Whatever approach you take, the procedure usually includes cooling the oil first so that it solidifies, transferring it to a different container if necessary, or composting it.
1. Pack it before throwing it in the trash
The simplest method of disposing of used olive oil is to place it in an airtight, unbreakable container before disposal to a waste point. After you’re done cooking, let the oil cool before putting it in the containers. Do not make the mistake of using plastic bags for olive oil disposal.
2. Let the olive oil solidify or freeze it
This method may be time-consuming, but it will be worth it if you don’t like the idea of liquid in your trash can. Allow the olive oil to cool when you are done using it. It will naturally begin to solidify. Also, you may freeze it.
Once it has solidified, wipe off any remaining oil with a paper towel and dispose of it in the trash. Freezing the oil will be a great option if you wish to recycle it for future use.
3. Household hazardous waste disposal
This is the most convenient method. There are businesses that specialize in the disposal of domestic hazardous trash that offer a doorstep pick-up service. You can get in touch with such businesses and use their services for disposing of oil.
4. Set up a grease disposal system
This must be your best option if you use olive oil frequently for any purpose. Each restaurant has a grease disposal system in place. You can even install it inside your home. A system kit for a grease disposal system can hold up to 2 lbs of oil without needing to be changed.
5. Use it for compost
You can compost the olive oil by combining it with vegetable and fruit waste, leaves, and other compostable materials. Take a few pieces of the solidified olive oil slab and add them. Be careful; too much olive oil may interfere with natural processes.
What Can Recycled Olive Oil Be Used For?
Olive oil can be recycled or used once again in several different ways. We’ll look at a few ways you can recycle used olive oil.
Freeze for later use:
- You can freeze any olive oil that is left over after cooking if you don’t want it to go to waste. You can keep olive oil in the freezer for up to two years.
Production of Biodiesel from olive oil:
- There are industries that turn waste olive oil into biodiesel, which is both environmentally friendly and long-term effective in the fight against global warming.
Make soap with olive oil:
- These days, producing soap is popular, and many individuals have started doing it at home. You can turn your olive oil into an organic soap. However, use caution if doing it at home.
Use for cleaning:
- Olive oil is not only beneficial cooking oil. It can also be used as a cleaning tool to nourish surfaces and remove grease, dirt, and stains. While you wouldn’t want to use your beautiful artisanal bottles for cleaning, it would be best to use used olive oil for that.
There are numerous additional uses for recycled olive oil, including manufacturing candles, moisturizing lotions, and many others. I recently wrote an article on expired olive oil uses, so make sure to check that out, too.
