Most restaurants hire two companies for grease: one for fryer oil, one for the grease trap. Bundling both with a single vendor is usually simpler and cheaper — one schedule, one invoice, and a used cooking oil rebate that offsets your trap cost. Here's the breakdown.
One vendor or two for restaurant grease?
Every commercial kitchen produces two grease streams: used cooking oil from the fryers and FOG in the grease trap. Historically these were handled by two different kinds of company — a rendering/oil hauler and a septic-style pumper. There's no rule that says they have to stay separate.
The case for one vendor
- One schedule. No reconciling two calendars or wondering which company is coming when.
- One invoice. A single bill — with your oil rebate and trap charge in one place.
- One contact. When something's wrong, you call one number and one dispatcher owns it.
- Lower combined cost. Shared routing removes a duplicate trip charge, and your used cooking oil rebate offsets the grease trap bill.
- One clean paper trail. Inspectors asking about oil disposal and FOG compliance get consistent records from one source.
When two vendors might make sense
If you already have a locked-in contract you can't exit, or a specialist relationship you're happy with, splitting can be fine in the short term. But check the contract — many have exit clauses operators don't notice — and compare the all-in cost, including both trip charges, against a bundled quote.
How GreaseGiant does both
GreaseGiant is built as the one grease company for the DMV: we collect and pay you for fryer oil, and we pump and clean your grease trap, on one account. See the one-company bundle, or your local page for Baltimore, Washington, DC, or Northern Virginia.
Frequently asked questions
Should I use one company for used cooking oil and grease trap?
For most restaurants, yes. One vendor means one schedule, one invoice, one point of contact, and usually a lower combined price than two specialists — plus your used cooking oil rebate can offset your grease trap cost.
Is it cheaper to bundle grease services?
Generally yes. The same truck and route covering both services avoids a duplicate trip charge, and the value of your fryer oil works against your trap bill.
Does one company for both create a single point of failure?
It's the opposite in practice — with one dispatcher owning both services, nothing falls through the cracks between two vendors blaming each other. You get one accountable contact and one clean paper trail.
