How To Properly Dispose of Grease and Oils From Food Preparation

Common Sources of Oil and Grease 

• Meat trimmings (fried, baked meats)
• Cooking Oil
• Salad Dressing
• Mayonnaise
• Melted Butter
• Bacon Drippings

Proper Disposal of Grease and Oil 

1. Solidify thin, liquidy fats with absorbent material. It is most tempting to just pour light oils down the drain; after all, you can't just pour them in the garbage! However, you can use coffee grounds or kitty litter (or even some leftover powder laundry detergent) to absorb the liquid and then dispose of the solid waste. If you want to go super green, you can even make your own kitty litter from recycled paper!
2. Filter out heavy grease and fatty solids. When boiling meat or any time fats and water mix, it's easy to just pour it all down the drain. However, you can simply cover the drain with one or two layers of paper towel (or a large coffee filter) and use them as a filter to catch softer, more solid fats and grime when they are already heavily mixed with water. Then discard the "filter paper" in the trash.
3. Wipe out greasy pots and pans. It's messy, and it can be annoying, but it's safer and healthier than rinsing the grease and grime down the drain. If you do it soon enough after cooking, it also cuts down on the elbow grease needed to get pots and pans clean. THAT'S worth the effort!
4. Fill a safe container and discard the container. An empty coffee can, or better, an empty plastc food container (they are usually not recyclable) with a tight fitting lid can be used to hold the grease or oil, and you can simply throw that out with the trash. Easy peasy. Just make sure that the grease or oil has cooled first - you don't want to dispose of hot grease for a number of safety reasons.
