Is a grease trap cleaning business profitable?
We looked at how long 1,015 of them have lasted.

We cannot tell you whether grease trap cleaning is profitable. Nobody can, from the outside — margins depend on route density, disposal costs, what you pay for a truck and what your local market will bear, and none of that is public.

What we can tell you is how long these businesses last. Of 1,015 grease trap contractors who state how long they have been trading, 48% have been at it for 40 years or more, and barely one in a hundred is under five years old. Businesses that do not make money do not last four decades. That is not a profit figure, but it is the strongest signal available without seeing anyone’s books.

What we can and cannot see

We run a directory of this trade, so we can see what contractors publish about themselves. We cannot see revenue, margin, or whether anyone is enjoying it.

There is also a bias in this data that we would rather name than have you spot: a directory lists businesses that exist. The ones that failed are not in it. So “48% have traded 40+ years” does not mean 48% of people who start one survive four decades — it means that of the operators trading today, nearly half have been at it that long. Those are different claims and only the second is supported.

That distinction matters, and it still leaves the finding useful. Read it as a description of who you would be competing against rather than a survival rate.

How long these businesses have been trading

The shape of that table is the finding. This is not a trade of new entrants. It is a trade of incumbents, and the distribution is weighted so heavily toward the top that the under-five-year group — eleven businesses out of a thousand — barely registers.

For anyone considering starting one, that is the single most useful fact on this page. You would not be entering an empty field. You would be entering a field where half your competition has been servicing the same kitchens since before you were born.

The oldest names in grease trap work are not grease trap companies

Sixty-eight businesses in the directory claim ninety years or more. We looked at the oldest, expecting data entry errors, and found something more interesting.

The oldest entries are rendering and tallow companies: businesses founded in the 1870s, 1880s and 1900s to collect animal fat and process it into soap, candles and feed. DAR PRO Solutions traces to Darling Ingredients, founded in 1882. Birmingham Hide & Tallow dates to around 1900. MOPAC, now a used cooking oil collector, counts from 1877.

Grease traps as we know them are a twentieth-century plumbing fixture. These firms predate them entirely. What happened is that an industry built on collecting fat from butchers and slaughterhouses found that restaurants also produce fat, and that somebody has to pump it out. The modern grease services trade grew out of rendering, and the oldest operators in it are the ones who were already in the fat business when kitchens started needing help.

That is worth knowing for a practical reason as well as an interesting one. If you are competing in a market where one of the incumbents is a rendering company with a 140-year-old collection network and its own processing plant, you are not competing on price. You are competing on responsiveness, on service to accounts too small for them to prioritise, and on being the one who actually answers.

What this means for what you spend

Put this next to what we found earlier. There is nobody selling grease trap leads, so you cannot buy your way in. And 87% of this trade advertises round-the-clock availability while only 43.5% publish their opening hours, so the incumbents are not actually hard to out-execute on the basics.

If you are new, spend almost nothing at first. Your competition is long-established and relationship-heavy; you will not displace a 40-year account with advertising. What you can do is be findable and responsive in the moments the incumbent is not — nights, weekends, the small account they keep deprioritising. That costs an afternoon of listing work, not a budget.

If you are established and stuck, the question changes. You already have routes and relationships. The problem is usually not visibility but leakage — enquiries that arrive and are never followed up, a form that fails quietly, quotes that go out and are forgotten. That is worth finding before you spend anything on getting more enquiries.

If you are growing into a new territory, that is when marketing earns its keep — because you have no route density and no relationships there, and the two things that normally bring work have nothing to work with.

We will not put a number on it here. Any agency quoting you a budget before knowing your route density, your close rate and whether your existing enquiries are landing is guessing, and so would we be.

So: is it profitable?

The honest answer is that we do not know, and neither does anyone publishing a market-size report about it.

What we can say is that it is durable. Nearly half the operators trading today have been trading for forty years, the newest cohort is vanishingly small, and some of the oldest names have been in the fat business since the 1870s. Trades that do not pay do not look like that.

That is a reason to take the work seriously, and also a reason to be realistic about how quickly you would take share from it.

How we measured this

All counts are from the GreaseTrapLocator database on 2 August 2026. Of 1,914 published grease trap contractor listings in North America, 1,015 state a number of years in business; every figure here describes that 1,015, not the full 1,914 and not the trade as a whole.

Three caveats we would rather state than have you find. Self-reported: years in business is what the business says, not something we have verified against incorporation records. Survivorship: a directory lists businesses that exist, so failures are absent and these figures describe today’s operators rather than the odds of surviving. Lineage counts as trading: several of the oldest entries count from the founding of a predecessor business in a related trade — the rendering firms above being the clearest case. That is how those companies describe themselves, and we have reported it as such rather than second-guessing it.

This is directory measurement, not client results. We have no client results in this trade to report, and we say so on the evidence page.
