Grease is a semi solid, thick and oily lubricant used to prevent joint friction in machineries. Grease can also be oily residues from meals. You hear something like “I can eat loads of Mac burgers or Chinese takeout, they are so greasy.” Greasy in that context means the food is oily or buttery. So substances like vegetable oil, bacon grease, frying oil and cooking butter can be considered as grease.

​​​Problems of grease.  

As useful and necessary grease has become in human lives, it can be a real headache, when it comes to disposing it. Grease, when not properly disposed, can cause fresh water pollution, hence leading to ecological damages to all the present aquatic life; plants and animals alike.

To make you more concerned, grease pollution can be carcinogenic to human beings. It can also drain your pocket because you will have to replace your pipes and fix your drainage system when grease clogs it.

When it manages to leave your own building into the public sewer system, the deposit keeps getting larger and it can combine with other solid wastes (due to their sticky nature) to block the insides of sewer pipes. This can cause extreme flooding for a whole city.

​​​​The proper way to dispose grease

1. Put them in sealed containers: for grease that will not solidify, e.g. your vegetable oil, get an empty container, preferably with tight lids and pour the grease into it. Do this for all your available unused grease. Then you can add it to the rest of your garbage, where the waste disposal company will come get it and take it to the appropriate disposal sites. For the ones that can solidify, you can even put them in the fridge to quicken the freezing process. Put them in a plastic bag and throw them with the rest of your garbage. So start saving empty jars for this purpose.
2. Get a grease trap: A grease trap is a device that is used to remove oil and grease from drainage water. It is usually installed in the drainage system. If your mansion can afford it, then fine. But for commercial places that use greases often, it is best to buy a grease trap. Restaurants and food processing industries without grease traps are usually fined, and honestly, the amount you keep paying as fines will get you a grease trap. This way, you can pour all the grease you want down the drain without fear of clogging the pipes.
3. Keep reusing: once you’ve used it once, filter it to remove particles from the first usage, and use it again. After using it a few times, there won’t be any left. For the butter and flavored oil, add it to your homemade baked goods during baking, use it as flavor for your stews and sauces. That way, there is no grease to pour down the drain.
4. Make it compost: your used oil; vegetable oil precisely, can be used to make compost manures for your garden. Though it should be used in small quantities because the scent can attract pests to your flowers and veggies. Large quantity can also prevent proper air and water flow within the soil. So stir a little quantity of it properly with your garden soil and watch your plants thrive.
5. Covert them to biodiesel: biodiesel is a renewable fuel source made from different kinds of vegetable oil. It is environment friendly. It can be used to power diesel engines and can be used as heating oil. Used or new vegetable oil is the main ingredient in making biodiesel, so add the ones you wanted to dispose to the remaining ingredients, and have yourself a nature friendly fuel.

A whole street once got flooded basements because of clogged pipes. When the pipes were checked, they were filled with all manner of grease products because the occupants of the neighbourhood kept pouring their grease down the drain. It took a lot of money to get their basements cleared and the pipes restored. Many useful things that were kept in their basements got water logged. You can avoid all these stories by doing the right thing. Dispose your grease the right way.
