How to dispose of Cooking Grease Traps & Grease in California

California rules

Many cities offer used cooking oil recycling. Check with your waste hauler.

Never pour grease down drains — it causes sewer blockages and 'fatbergs.'
Let grease cool and solidify, then scrape into a sealed container and put in trash.
Large quantities of cooking oil can be recycled into biodiesel at collection centers.
Clean grease trap components and replace filters according to manufacturer instructions.
