Don’t Dump it Down the Drain! Discover the Proper Way to Discard Deep Fryer Oil

Deep-frying is a delicious and convenient way to prepare food, but it’s essential to dispose of the used oil properly. Improper disposal of deep fryer oil can harm the environment and pose safety hazards. In this comprehensive guide, we will explore the various methods to discard deep fryer oil safely and responsibly.

Methods of Disposal

1. Solidify and Trash

Materials:

• Newspaper or paper towels
• Heat-resistant container (e.g., metal can or glass jar)

Steps:

1. Spread newspaper or paper towels on a flat surface.
2. Pour the cooled oil onto the paper towels.
3. Let the oil solidify for several hours or overnight.
4. Once solidified, transfer the paper towels to a heat-resistant container and dispose of them in the trash.

2. Recycle

Materials:

• Empty plastic bottles or jugs
• Funnel

3. Biodiesel Production

Materials:

• Large container (e.g., 5-gallon bucket)
• Methanol
• Sodium hydroxide (lye)

Steps:

Caution: This method involves handling hazardous chemicals. Proper safety precautions must be taken.

1. Follow specific instructions for biodiesel production, which can be found online or from biodiesel conversion kits.
2. Mix the used oil, methanol, and sodium hydroxide according to the instructions.
