TL;DR
You start yellow grease in Illinois on paper, not with a truck. File an LLC with the Secretary of State ($150), get a free EIN, register taxes, then confirm kitchen-grease licensing with the Department of Agriculture under 225 ILCS 610. Chicago adds its own business license. Confirm every fee and form with the board. Nobody can promise approval time.
Do you need a license for yellow grease in Illinois?
Yes. Collect kitchen grease as a business in Illinois and you are looking at a Department of Agriculture license under the Dead Animal Disposal Act, plus the usual company and tax registrations. Chicago and some towns add a local business license on top. Confirm your exact model with the Bureau of Animal Health and Welfare before you pump a gallon. [1]
That is the whole answer. The rest is why people get it wrong.
Illinois did not write a cute standalone yellow grease permit. It parked kitchen grease next to packing house refuse and dead animal disposal. The statute is 225 ILCS 610. The rules sit in 8 Ill. Adm. Code Part 90. [1] [2]
The short title reads plainly: this is the Illinois Dead Animal Disposal Act. Grease lives in that world. Read the Act and Part 90, not a Facebook thread. [1]
A one-time favor for a relative's diner is not the fact pattern the bureau cares about. A paid route is. So is a tote program. So is a weekly haul to a renderer or a biodiesel plant.
Processing is heavier. Heat, settle, centrifuge, or cut a spec product on your own pad and you start looking like a plant. I would not do that in year one. Haul to a licensed renderer. Keep the yard boring.
A city FOG hauler list is not the state license. Do not treat it like one. Downstate paper is not a Chicago hall pass either.
I would not spend on a truck until IDOA says, in writing, whether you need a collector license, a plant license, or some other class. Email counts. Save the reply.
How much does yellow grease cost in Illinois?
People mash three prices together. The commodity. The license fees. The cash it takes to stand up a route. Three different numbers.
The only startup figure I will print without flinching is the Secretary of State LLC filing. Illinois charges $150 to file articles of organization for a domestic limited liability company. [3] A federal EIN is free on the IRS site. The IRS says it plainly: applying for an EIN is a free service offered by the agency. [4]
I will not invent the IDOA collector or plant fee. Pull the current application. Chicago's business license fee sits on the city's pages and can move. Confirm it the week you file. [12]
Yellow grease as a product is usually priced by the pound against FFA, moisture, and insolubles. USDA Agricultural Marketing Service puts yellow grease on the National Weekly Ag Energy Round-Up. [6] That report is a public benchmark. It is not your bid from a plant in Joliet, Decatur, or East St. Louis.
Nobody keeps a clean public Illinois-only grease index. The closest free series is that USDA weekly report. Anyone handing you a single "Illinois price" with no week, no spec, and no location is selling a story.
The cash that actually hurts is the truck, locked totes, a legal washout, commercial auto, and pollution liability. Those quotes change. Get them in writing the week you buy. A used tank setup can be a local beater or a purpose-built unit. I will not pretend I have your 2026 dealer invoice.
Pay restaurants and that is cost of goods. Collect free and your cost is labor, fuel, and spill risk. Either model can work. The free model dies the week a competitor waves a check.
| Line | Public figure | Confirm with |
|---|---|---|
| Domestic LLC articles | $150 | Illinois Secretary of State [3] |
| EIN | $0 | IRS [4] |
| IDOA kitchen grease license | Do not guess | Dept. of Agriculture [1] |
| Commodity yellow grease | Weekly, spec based | USDA AMS plus your plant [6] |
| Chicago business license | Local, variable | City BACP [12] |
How long does yellow grease take in Illinois?
Entity formation can be fast. A license decision and a real route run on a slower clock. Online LLC filings with the Illinois Secretary of State often come back sooner than a mailed packet, but I will not reprint a processing promise the state did not give you. Ask Business Services what they are seeing this month. [3]
An EIN is usually immediate if you file online with the IRS. [4]
IDOA review is its own queue. I will not invent a day count. Call the Bureau of Animal Health and Welfare. Ask what a complete kitchen-grease file looks like right now. Build slack. No article gets to promise you a date.
Restaurant accounts take longer than paper. A cold week in a Chicago suburb buys you two maybe-calls and a stack of "we already have a guy." Plan on months of density work unless you bought a book of accounts. Buy a book and you also bought the bad contracts and the theft history. Walk the stops.
A first load still needs a renderer account, a spec, and often a sample. That runs a week or three after you have oil. Do not promise a restaurant a Monday start you have not cleared with the plant.
CDL school, a special waste question, or a building permit for processing do not run on the LLC clock. Start those the same week you file articles if you truly need them. Most new collectors do not need a plant.
What paper do you file first to start yellow grease in Illinois?
File the company before you print tote stickers. That is the order I would actually use.
Search the name, then file domestic LLC articles with the Illinois Secretary of State. The Illinois Limited Liability Company Act is 805 ILCS 180. The filing fee on the state's organizing guide is $150. [3] [9] Get a free EIN next. [4] Then open Illinois tax accounts on MyTax with Form REG-1 so payroll, withholding, and sales-tax questions have a home. [5]
Then write IDOA. Ask which license class matches a collector who does not cook oil. Attach a plain description: totes, tank truck, destination plant, no on-site rendering. Apply only after they point you at the right form. [1] [2]
Same week, ask Illinois EPA in writing whether your loads are special waste under 35 Ill. Adm. Code 809. Destination matters. A licensed renderer is a different story than a mystery dock. [10]
Trade under a name that is not the LLC's legal name and that is an assumed-name filing with the county clerk. Fees vary by county. Confirm with the clerk where the company sits. You need an Illinois registered agent with a street address. I would not try a PO box and hope.
Local business licenses come after you know the city that will actually see your truck. Chicago goes through Business Affairs and Consumer Protection. [12] Suburbs have their own clerks. Do them one town at a time as the route gets real.
Insurance binders and the truck title sit near the end of this list on purpose. Paper first. Steel second.
Want to see how another big state stacks the same pile? The Texas writeup is a useful contrast: how to start yellow grease in Texas.
What does the Illinois Dead Animal Disposal Act actually cover?
It covers more than carcasses. That is the part new collectors miss. 225 ILCS 610 is the Dead Animal Disposal Act. Kitchen grease is in that world, not in a separate "used cooking oil board." [1]
8 Ill. Adm. Code Part 90 is where the operational rules live. Vehicles, premises, records, and license mechanics show up there. Read Part 90 before you call so you are not asking the bureau to do your homework. [2]
I would ask IDOA, in one short letter, three things. Do I need a license to collect kitchen grease and haul it to a licensed renderer? Which application? What records do you want on pickup source, weight, and destination? Keep their answer with your corporate book.
Add cooking, settling, or a spec tank farm later and you ask again. The answer can change when the operation changes. A tote route and a plant are not the same file.
Out-of-state plants do not erase Illinois rules on the Illinois side of the driveway. If the oil is picked up here, start with IDOA here.
This is also why copying a California starter guide blindly fails. Different statute. Different agency. Same grease. Different paper.
Do Chicago and Cook County add extra grease hauler rules?
Often, yes. A state IDOA license does not replace a Chicago business license. The City of Chicago issues general business licenses through Business Affairs and Consumer Protection. Confirm the current class and fee on the city's licensing pages before you advertise a Chicago route. [12]
Some municipalities keep FOG programs and lists of haulers they will allow on grease interceptors. Getting on a list can help you win accounts. It is still not the Dead Animal Disposal Act license. Do both if both apply.
Cook County and home-rule towns can stack health, environmental, or vehicle rules the state never mentioned. Unincorporated county is not the same as a suburb with its own clerk. I would call the clerk in every town where you will park totes overnight or wash a truck.
Chicago alleys are a theft and spill theater. Locked lids, photos, and a written restaurant contract matter more here than they do on a quiet Downstate highway. Ordinary theft is still 720 ILCS 5/16-1 if someone cuts a lock and drains your tote. [11]
I would not launch a Loop-and-neighborhood route the same week I launch a Peoria route. Density, parking, and city paper are different jobs.
What trucks, tanks, and bins do you need for an Illinois route?
You need closed containers, a legal way to move them, and a legal place to wash. That is the equipment conversation. Branding can wait.
Most new Illinois collectors use caged totes or a vacuum tank, not open drums. Restaurants hate spills more than they hate a weak payout. Locked lids cut casual theft. I would not drop an unlocked drum behind a 24-hour diner and call it a system.
Watch weight. Interstate commercial motor vehicles at 10,001 pounds or more generally need a USDOT number. FMCSA's registration page is the rule to read, not a truck-lot rumor. [7] A CDL generally enters the picture at 26,001 pounds GVWR. Plenty of collectors stay under that on purpose. Confirm the actual GVWR on the door sticker, not the salesperson's story. [14]
Illinois intrastate plate and USDOT triggers belong to Secretary of State vehicle services and FMCSA. I will not invent an extra Illinois-only cutoff. Ask with your VIN and GVWR in hand.
Wash water is not a storm-drain product. Rinse tanks and you need a sink, interceptor, or plant that can take that water. Illinois EPA will not smile at an alley hose. Special waste rules in 35 Ill. Adm. Code 809 are the reminder to ask before you improvise. [10]
Buy fewer totes than your optimism wants. Parked empty plastic does not pay for itself. Add stops, then add plastic.
How do you buy restaurant grease and sell it to a renderer?
With contracts, not handshakes. The restaurant needs to know who owns the oil, when you come, who pays whom, and who cleans a spill. The renderer needs a spec, a rejection rule, and a payment term. Write both before the first pump.
Decide the money model in the restaurant paper. Free pickup. A small payout. A rare paid-haul if they are a problem stop. I like simple. Complicated splits collapse when grease bids move two cents.
Theft is ordinary crime paper in Illinois unless a city wrote something extra. 720 ILCS 5/16-1 is the theft statute. [11] Locks, photos, and a police report help your insurer more than they recover a midnight load. Want a single packet of bin, theft, and renderer templates? YellowGreasePath sells a $149 one-time Bin + Theft + Renderer Kit at /start. You can also write the same paper yourself.
Get the renderer's incoming spec in writing. FFA, moisture, insolubles, temperature, and what happens on a reject. A rejected load is now your problem in a tank. Know the backup dock before Friday night.
Do not start processing to "capture more margin" in month three. That is how people buy a wastewater problem. Haul. Get paid. Learn density.
Texas keeps a clearer standalone collector story than Illinois does. If you like comparing license piles, read yellow grease license in Texas next.
How much does yellow grease sell for versus what a route costs?
The USDA weekly Ag Energy report is where I would look for a public yellow grease print, then I would ignore it as a contract. [6] Your plant will bid your spec, your volume, and your freight. A 400-pound tote route is not a tanker price.
Route cost is fuel, labor, insurance, tote loss, rejected loads, and the hours you sit in Chicago traffic. I have no honest statewide average for that. Anyone who publishes one without a year, a region, and a method is guessing.
In strong renewable-diesel years the grease check looks fat. In weak years you are paid like a trash hauler with a worse smell. Build a year-one model that still works if the USDA print drops. If it only works at last year's high, you do not have a business.
I would rather own 40 tight suburban stops than 120 random ones across three interstates. Density beats a vanity map.
Compare that discipline with how Tennessee starters and Alabama starters have to think about rural miles. Illinois has city density if you can stand the paper. Use it.
What insurance and tax registrations do Illinois collectors actually carry?
Register the company for Illinois taxes on Form REG-1 through MyTax. That is how withholding, sales tax, and related accounts get created. [5] Then ask the Department of Revenue, in writing, whether your grease sales are taxable. I will not guess you into an audit. Recycling and commodity sales can surprise people.
Hire anyone and you budget unemployment with IDES and workers' compensation under the Workers' Compensation Act, 820 ILCS 305. Illinois is not a "maybe later" state once you have staff. [8]
Insurance I would actually buy: commercial auto written to the real GVWR, general liability, and pollution liability. Cargo if the plant requires it. An agent who skips pollution to "save you money" is not doing you a favor. One interceptor backup in Oak Park costs more than the premium.
Name the LLC correctly on every policy. Name the renderer as additional insured if the contract says so. Keep certificates with the IDOA file.
Sales across the state line do not erase Illinois tax registration. They add destination questions. Ask IDOR. Do not take tax advice from a tote salesman.
Is used cooking oil special waste or used oil in Illinois?
Probably neither in the way people mean, but you still ask. Federal "used oil" rules in 40 CFR Part 279 are about petroleum used oil, not fryer grease. Citing Part 279 at an Illinois restaurant dock is the wrong program. [13]
Illinois special waste hauling lives in 35 Ill. Adm. Code 809. Whether your yellow grease counts as special waste depends on how it is managed and where it goes. A documented sale to a licensed renderer or biodiesel plant is a different fact pattern than oil you abandoned. [10]
I would send Illinois EPA a short description and the destination permit name. Keep the answer. If they want a special waste hauling permit, you do that before you scale. If they do not, you still keep pickup and delivery tickets like they might ask later.
Storm drains, soil piles, and "I'll just dump the water out back" turn a commodity route into an enforcement file. That is the environmental risk that actually bites collectors, not a RCRA code you misread on a forum.
Colorado and Arizona write this line differently. Useful if you also run trucks there: how to start yellow grease in Colorado and how to start yellow grease in Arizona.
What first-year mistakes burn new Illinois grease routes?
Buying the truck first. Skipping IDOA because a renderer said "you're fine." Launching Chicago without a city license. Paying too much for a Facebook "turnkey route" you never verified with the restaurants. Processing on a rented pad with no wastewater plan.
I would also skip fancy software in month one. A notebook and dated tickets beat an app you do not open. IDOA and the plant care about source, pounds, and destination. Give them that.
Do not sign an exclusive restaurant contract you cannot staff. Missed pickups are how you lose the account and how grease hits the interceptor. Be boring. Show up.
Do not run employees off the books. 820 ILCS 305 is waiting if someone slips on an alley grate. [8]
Do not treat neighboring-state paper as portable. Arkansas will not bless an Illinois tote. File Illinois first if the oil lives here.
What should you confirm with each board before you spend money?
Call IDOA Bureau of Animal Health and Welfare with a written description of your route. Confirm license class, current fee, vehicle rules, and records. Confirm they want the application before the first commercial pickup. [1] [2]
Call Illinois Secretary of State Business Services on the LLC file and, separately, Vehicle Services if the truck may trip commercial rules. Confirm the $150 articles fee is still the number on the current organizing guide. [3] [9]
Call Illinois Department of Revenue on REG-1 accounts and on taxability of grease sales. [5] Call Illinois EPA on 35 Ill. Adm. Code 809. [10] Call the city clerk or Chicago BACP for the local business license. [12] Call your insurer with GVWR and pollution in the first sentence.

Frequently asked questions
Do you need a license for yellow grease in Illinois?
Usually yes if you collect kitchen grease as a business. Illinois parks that activity under the Dead Animal Disposal Act, 225 ILCS 610, administered by the Department of Agriculture. You still need ordinary LLC and tax registrations. Chicago adds a local business license. Confirm your exact class with the Bureau of Animal Health and Welfare before you haul.
How much does yellow grease cost in Illinois?
The commodity price moves weekly and is spec based. USDA's National Weekly Ag Energy Round-Up is the public benchmark, not your plant's bid. Startup paper includes a $150 Illinois LLC filing and a free EIN. IDOA and Chicago license fees must be confirmed on current forms. Trucks, totes, and pollution insurance will dwarf the filing checks.
How long does yellow grease take in Illinois?
An EIN is often immediate online. An LLC can be relatively quick if you file online, but confirm current Secretary of State processing. IDOA review has no honest public day-count I will reprint. Route building usually takes months. Do not promise restaurants a start date until the plant and the bureau have both answered you.
Is yellow grease the same as used oil under Illinois EPA rules?
No. Federal used-oil rules in 40 CFR Part 279 cover petroleum used oil, not fryer grease. Illinois may still ask special-waste questions under 35 Ill. Adm. Code 809 depending on how you manage the material and where it goes. Ask Illinois EPA in writing with your destination named.
Do I need a Chicago license if I already have IDOA paper?
If you operate in Chicago, plan on a city business license through Business Affairs and Consumer Protection in addition to state paper. A Dead Animal Disposal Act license does not replace the city's license. Some suburbs also keep FOG hauler lists. Check each town where you will set totes or wash a truck.
Can I start yellow grease in Illinois as a sole proprietor?
You can operate as a sole proprietor as a legal form, but I would not. File the $150 domestic LLC with the Secretary of State, get an EIN, and keep grease liability off your house. Renderers, insurers, and landlords also prefer an entity. Assumed names still go through the county clerk if you trade under a different style.
Do I need a CDL or a USDOT number for a grease truck?
Interstate commercial motor vehicles at 10,001 pounds or more generally need a USDOT number per FMCSA. A CDL generally applies at 26,001 pounds GVWR. Many collectors stay under the CDL line on purpose. Confirm Illinois plate and intrastate rules with Secretary of State Vehicle Services using the truck's actual GVWR.
Who buys yellow grease in Illinois?
Licensed renderers and biodiesel or renewable-diesel feedstock buyers. Get a written spec, a rejection rule, and payment terms before you collect a restaurant. USDA's weekly Ag Energy report is a public price check, not a contract. A small tote route will not get a tanker bid. Ask the plant what volume even gets you an account.
Is restaurant grease theft a separate Illinois crime?
Illinois usually treats stolen grease as ordinary theft under 720 ILCS 5/16-1 unless a city wrote a tighter ordinance. Locks, dated photos, and written exclusive language help more than a special statute would. File a police report for the insurer. Do not chase a tanker down an alley. Replace the oil and fix the contract.
Do I need workers' compensation for a one-person Illinois route?
If you have no employees, the Workers' Compensation Act analysis is different than if you hire a helper. The moment you put someone on the truck, budget coverage under 820 ILCS 305 and unemployment with IDES. I would not pay a "contractor" to pump grease off the books. Alley slips are predictable.
Can I process yellow grease at home in Illinois?
I would not. Heating and separating oil looks like a plant to IDOA and can drag in wastewater and air questions. Year one, haul to a licensed renderer. If you later want a process site, ask IDOA and Illinois EPA before you buy a cooker. A garage hobby setup is how people buy an enforcement file.
What records should an Illinois collector keep?
Ask IDOA what Part 90 and your license class require, then over-keep. I would log restaurant name, date, approximate pounds, destination plant, and ticket numbers. Keep contracts, spill photos, and the EPA email about special waste. Plants will ask for incoming paperwork. So will an insurer after a claim.
