How to Properly Dispose of Cooking Grease

October 21, 2025

Cooking grease is an unavoidable part of preparing meals, but how you handle it afterward can have a significant impact on your plumbing and the environment. Proper disposal prevents clogs, reduces waste, and supports sustainable practices. Understanding the best methods for managing used cooking grease ensures both a cleaner home and a healthier planet.


Avoid Pouring Grease Down the Drain

The first crucial step in handling cooking grease is to never pour it down your sink or garbage disposal. This common mistake often leads to major plumbing issues. According to the Food and Agriculture Organization, by 2025, global consumption of vegetable oils and fats is expected to increase by 25%. As grease cools, it solidifies and adheres to the pipe walls, restricting water flow and eventually causing blockages that can result in costly repairs. Avoiding this habit is the foundation of proper grease management.


Store and Recycle Used Cooking Grease

Instead of pouring grease away, store it in a safe container once it cools. Use a jar, tin can, or any sealable container to hold the grease until you are ready to dispose of it. Check whether your local waste management offers a grease recycling program. Grease recycling programs convert used cooking oils into biofuels or other sustainable products, reducing environmental impact. Incorporating grease recycling into your routine supports responsible waste management while preventing plumbing problems at home.


Repurpose Grease for Future Use or Compost

If recycling options are unavailable, consider repurposing the grease. Strain cooled grease to remove food particles and store it in the refrigerator for later cooking. Plant-based oils, such as olive or canola, can also be added to compost, providing nutrients that improve soil quality and support plant growth. These alternative uses ensure that cooking grease does not go to waste while contributing positively to your household or garden.


Proper disposal of cooking grease is essential to prevent plumbing problems and protect the environment. According to San Diego Gov, grease clogs in residential pipes are a common and costly issue, emphasizing the importance of responsible management. Whether through storage, repurposing, or grease recycling programs, mindful handling reduces risks and supports sustainable practices.
