Restaurant Used Oil Collection
in Los Angeles, CA
Used cooking oil is a commodity, not just waste. Proper collection prevents illegal dumping fines, reduces grease trap loading, and — with the right hauler — generates a small rebate. California law prohibits disposal of used oil in drains or trash.
25,000 kitchens, one commodity most operators mismanage
Local anchors: Koreatown, Downtown Arts District, Hollywood, West Hollywood, Boyle Heights, Silver Lake, Los Feliz.

Why LA restaurants call about used oil
Used oil collection in Los Angeles, answered
How often does a Los Angeles restaurant need to schedule used oil collection
CalRecycle guidance and LA County practice both point to weekly collection as the baseline for high-volume operations. In practice, Koreatown Korean BBQ and East LA carnitas kitchens can require more frequent pickups given the volume of oil cycled through daily service.
What makes a hauler 'registered' under California law
CalRecycle maintains a list of registered used oil haulers authorized to collect and transport used cooking oil in California. The hauler must appear on that list and provide a signed manifest at each pickup — a vendor who only offers cash and no paperwork does not qualify.
Can a restaurant legally pour used oil down the drain in Los Angeles
No. California Health & Safety Code §118945 explicitly prohibits disposal of used cooking oil in drains, trash, or on the ground. Violations carry fines up to $10,000 per incident and are enforceable by CalRecycle and local environmental health agencies.
How long do I need to keep collection manifests
LA County requires restaurants to retain signed collection manifests for 3 years. Store them on-site or in an accessible digital format — auditors can request them at any routine inspection, not just during a complaint-triggered visit.
Do restaurants actually get paid for their used cooking oil
Many do. Used cooking oil is a feedstock for biodiesel and other rendered products, and registered haulers often pay a per-gallon rebate when collected volume is consistent and uncontaminated. High-volume fryer operations in Hollywood and Boyle Heights are typically the strongest candidates.
Does used oil volume affect my grease trap
Yes, directly. Oil that is not collected cleanly ends up loading your grease interceptor faster, increasing pump-out frequency and the risk of a FOG-related drain backup. LA's warm climate means there is no seasonal slowdown in grease trap biological activity, so over-loaded traps become a year-round problem.
What happens if my regular hauler stops showing up
Your 3-year manifest record develops a gap, and your storage container fills to the point where improper disposal becomes tempting or accidental. The fix is a same-day or next-day replacement pickup from another CalRecycle-registered hauler — Boh can coordinate that through the vendor network.
Is used oil collection related to hood cleaning or grease trap service
All three are part of the same grease management chain. Excess oil that bypasses collection ends up in drain lines and traps, and insufficiently collected fryer residue contributes to hood and flue grease buildup. Operators who coordinate all three services on a shared schedule tend to have cleaner systems and fewer emergency calls.
