TL;DR
Delaware does not publish a local yellow grease price. Collectors sell against USDA weekly quotes, then lose freight and quality. You need a Delaware business license. Confirm with DNREC whether your loads need a solid waste transporter permit. There is no standalone grease-collector card. First-year cash goes to a truck, bins, insurance, and waiting time, not a magic state fee. Confirm every board fee before you pay anyone.
How much does yellow grease cost in Delaware?
There is no official Delaware yellow grease spot price. The public number people use is the USDA Agricultural Marketing Service weekly yellow grease quote, usually in cents per pound. Your Delaware netback is that quote minus freight, moisture, and free fatty acid discounts. Restaurants may get paid, get free pickup, or pay you. That split is private. It is not on a state board.
USDA AMS posts yellow grease in the National Weekly Ag Energy Roundup and in related feedstuff sheets. Those prints are Midwest and national, not Wilmington. [1] USDA ERS also keeps a U.S. bioenergy price series that includes yellow grease as a biodiesel feedstock. [2] Treat those figures as a ceiling you argue from, not a check you will cash.
Delaware is a three-county market. New Castle has the dense kitchens. Sussex has a summer spike around the beach towns, then it goes quiet. Kent sits in the middle. Freight to a Mid-Atlantic renderer or an East Coast biodiesel plant will eat a real slice of the USDA print. If a broker quotes you "the USDA number," ask them to write the freight and the FFA slide in the same email.
I would not underwrite a truck loan on last year's high print. Yellow grease moved hard when renewable diesel demand tightened used oils. It also gave that back. Pull the current AMS sheet the week you bid a route. Nobody has a clean public dataset of what Delaware restaurants actually receive per pound. The closest public figure is that USDA weekly quote.
USDA AMS publishes yellow grease in cents per pound on a weekly national sheet, not as a Delaware delivered price. [1]
If you want a feel for how a bigger, more licensed market prices the same oil, read yellow grease cost in California. The chemistry is the same. The paper is not.
Do you need a license for yellow grease in Delaware?
Yes, you need a Delaware business license if you collect, haul, or sell yellow grease as a business. Delaware does not issue a standalone yellow grease collector card. Confirm with DNREC whether your loads fall under a solid waste transporter permit. If you label and sell feed-grade fat, ask the Delaware Department of Agriculture about commercial feed registration. [3][4][5][14]
Start with the Division of Revenue. Title 30 of the Delaware Code is the business license and gross receipts chapter. Fees sit on a schedule the state can change. Confirm the current amount on the Division of Revenue business license page before you write a check. Do not pay a coach who says they will get you "the grease license." That product does not exist here. [3][15]
DNREC's Regulations Governing Solid Waste (7 DE Admin. Code 1301) are the rulebook for solid waste facilities and, in practice, for a lot of hauling questions. Used cooking oil going to a renderer is often handled as a commodity. The same oil dumped or abandoned is waste. Call the solid waste program and describe your exact flow, restaurant to tote to renderer. Get the answer in writing. [4][14]
Forming a Delaware LLC is a separate filing at the Division of Corporations. That office publishes formation and annual tax amounts in the LLC Act and on its fee materials. Confirm those numbers on the current schedule. An LLC is not a hauling permit. [6]
I would do the Revenue license, the entity filing, insurance, and the DNREC phone call before I bought a single bin. Paper first. Steel second.
How long does yellow grease take in Delaware?
There is no published yellow grease processing time in Delaware because there is no dedicated yellow grease permit clock. Formation, a business license, insurance binders, and a DNREC determination each have their own queue. Confirm current turnaround with each board. Nobody can honestly guarantee your start date. Anyone who does is selling smoke.
The oil itself has a clock. Fryer oil that sits in a vented bin picks up rainwater and the free fatty acid number climbs. Biodiesel buyers care about that. A weekly restaurant stop is normal. Two weeks is already sloppy in July. Sussex beach accounts can double in June and vanish in October. Build the route for the winter kitchen count, not the August patio.
How long from first phone call to first legal pickup? I would budget several weeks for entity, license, insurance, and a written DNREC answer, then more if you need commercial parking or a tank. I will not put a day count on a state form. Boards change staffing. Confirm.
Haul time across Delaware is short. You can cross the state in a morning. The delay is never miles. It is a restaurant that is not ready, a full tote, or a renderer that only receives on Tuesdays.
If you are comparing startup drag in other states, yellow grease cost in Connecticut is the nearer paper path to read next.
What is yellow grease worth per pound on the USDA sheet?
USDA AMS quotes yellow grease in cents per pound on a weekly sheet. That is the number traders argue about. It is not a Delaware delivered price. Your contract will name a basis (AMS, a private broker sheet, or a fixed cent) and then subtract moisture, insolubles, unsaponifiables, and FFA. [1][2]
I will not print a fake current Delaware price. It would be wrong by next Friday. Pull the latest National Weekly Ag Energy Roundup. [1] ERS historical tables show how wide the band can get across marketing years. Used oils ran up when renewable diesel plants added capacity. They also fell. [2]
A clean, dry, low-FFA load is worth more than a wet bin. If you pay restaurants a flat dime when the AMS print is weak, you lose money. If you charge for service when the print is strong, you lose accounts. Write a formula, not a handshake.
EPA treats used cooking oil as an approved renewable diesel and biodiesel feedstock under the Renewable Fuel Standard pathways. That demand is why the USDA quote exists in the first place. [7][8] You will not file RINs as a small collector in most cases. The plant will. Your job is a clean bill of lading and a seal.
Quality is the only lever you fully control in Delaware. Freight is mostly geography. The USDA sheet is public. Your discount stack is not.
What first-year costs hit a Delaware collector besides the oil?
The grease is not your big check. The truck is. A used box truck and poly totes will get a small Delaware route moving. A new vacuum truck will not make you more legal. It will make you more in debt. I would not buy new stainless in year one unless you already have signed density in New Castle County.
Bins, lids, and locks matter more than paint. Theft of used cooking oil is a real national problem. Delaware does not need a special grease-theft statute for it to be a crime. It is theft of property. Use seals. Photograph them. Keep a log.
Insurance is not optional. Commercial auto, general liability, and a serious talk about pollution coverage. Ask a broker who has written tank or waste accounts in Delaware. I will not invent a premium. Premiums move with your driving record and where you park.
Parking and spill response cost money people forget. You cannot stage dripping totes behind a rental house in Newark and hope. Check county zoning. Keep absorbent, a shovel, and a written spill sheet in the cab.
YellowGreasePath publishes a $149 one-time Bin + Theft + Renderer Kit if you want our paper stack in one folder at /start. You can also build that file yourself from the statutes cited here. We are an independent publisher, not a filer.
Other first-year cash: fuel, a scale ticket habit, gloves, and the hours you spend waiting on kitchens. Labor is the line that wrecks hobby routes. Compare setup shape (not Delaware fees) with yellow grease cost in Illinois if you want a Midwest quote-adjacent market.
| Cost line | Public number? | Who confirms it |
|---|---|---|
| USDA yellow grease quote | Yes, cents per pound, weekly | USDA AMS [1] |
| Delaware delivered netback | No | Your renderer contract |
| Business license fee | Schedule, can change | Division of Revenue [3][15] |
| Solid waste transporter | Only if DNREC says you are in scope | DNREC [4][14] |
| SPCC plan | 1,320 gal aboveground trigger | 40 CFR 112 [11] |
Is yellow grease treated as used oil or solid waste in Delaware?
Typical yellow grease is not used oil under the federal used oil rule. EPA defines used oil as oil refined from crude oil, or synthetic oil, that has been used and contaminated. Vegetable and animal fryer oil does not meet that definition. [9]
EPA 40 CFR 279.1 limits "used oil" to crude-derived or synthetic used oil, so typical fryer yellow grease is not federal used oil. The regulation says: "Used oil means any oil that has been refined from crude oil, or any synthetic oil, that has been used and as a result of such use is contaminated by physical or chemical impurities." [9]
That does not make you unregulated. If you discard the oil, mix it with hazardous waste, or dump it, you have a waste problem. Delaware's solid waste regulations still apply to solid waste activity. [4] Confirm your fact pattern with DNREC. Do not take a forum post as a determination.
Brown grease from an interceptor is not yellow grease. It is a different material, wetter, and often a wastewater story. Selling trap grease as yellow grease is how you lose a renderer and, if you are unlucky, a lawyer.
Keep the streams separate. Fryer oil in a sealed bin. Interceptor waste stays in the FOG lane that the sewer authority already hates. EPA has spent years telling cities to control fats, oils, and grease in sewers. That campaign is about pipes, not your biodiesel drum. [10]
When does an EPA SPCC plan apply to a Delaware grease yard?
EPA's Spill Prevention, Control, and Countermeasure rule can apply to a Delaware yard that stores enough oil, including animal fats and vegetable oils. The federal trigger people miss is 1,320 gallons of aggregate aboveground storage. Completely buried capacity has a 42,000 gallon figure. Confirm your count with 40 CFR 112 and, if you are close, a PE who has written SPCC plans. [11][12]
40 CFR 112.2 says oil includes "fats, oils, or greases of animal, fish, or marine mammal origin; vegetable oils, including oils from seeds, nuts, fruits, or kernels." [12] Yellow grease is in that sentence. Five 275-gallon totes hold 1,375 gallons, which is already over the 1,320-gallon SPCC aboveground trigger in 40 CFR 112. [11]
Farm containers of animal fats and vegetable oils used only at a farm have a narrow counting break in the rule. A collection yard in New Castle County is not a farm. [11]
SPCC is a federal plan, not a Delaware grease license. You prepare it, implement it, and keep it. If you are over the threshold and you skip it, the fine risk is federal. I would rather spend money on secondary containment than on a pretty office.
A spill kit is cheap. A sheen in a ditch is not. Count every tote, tank, and drum that is not permanently closed transportation packaging in active transit. Then count again.
Who buys yellow grease from Delaware and how is the price set?
You will sell to a renderer, a biodiesel or renewable diesel plant, or a broker who already has those relationships. Delaware does not run a public auction for fryer oil. Price is a contract. The plant cares about the Renewable Fuel Standard pathway for used cooking oil, which is why they ask where it came from. [7][8]
Ask for the spec sheet before you pick up the first drum. FFA, moisture, MIU, and no trap grease will be on it. If they pay on rendered weight, water you hauled is a donation.
I would not sign an exclusive statewide deal in month one. Delaware is small. One bad exclusive can freeze you out of the only other dock within a reasonable drive. Keep a second outlet, even if it is a worse freight.
For how a desert market handles the same buyer math, yellow grease cost in Arizona is a useful contrast. Same USDA sheet. Different miles.
Seasonal Sussex volume is real. A buyer who wants a flat weekly gallon number year-round will hate a beach route. Say that in the first meeting. New Castle kitchens are the year-round base. Build price talk around winter gallons, then treat summer as overflow you already have a home for.
Can you sell yellow grease as animal feed in Delaware?
If you only deliver whole used cooking oil to a renderer, you are often just a supplier, not a feed mill. If you process, blend, label, or sell yellow grease as a commercial feed fat in Delaware, you are in Title 3, Chapter 17, the commercial feed law. Confirm registration with the Delaware Department of Agriculture before you print a feed tag. [5]
Federal feed rules still sit on top. 21 CFR 589.2000 is the ruminant feed ban on certain animal proteins. Do not play chemist with mystery fats. [13] A renderer will have its own incoming spec. Follow it.
I would not build a feed-grade story in year one unless a named buyer asked for it in writing. Most small Delaware collectors are selling a used oil feedstock, not bagged fat. Extra labels create extra inspections.
Confirm. Do not guess. If the buyer is a biodiesel plant, feed registration is usually the wrong errand. If the buyer is a feed blender, call DDA first and keep the email.
What paperwork should you keep on every yellow grease load?
Keep a paper trail that a cop, a buyer, or DNREC can read without you in the room. Restaurant name and address. Date. Approximate gallons or pounds. Bin ID. Seal number. Destination. Driver. A photo of the closed lid. That is the job.
RFS buyers may ask for transfer documents that show the oil is used cooking oil, not a virgin oil playing dress-up. EPA's pathway tables are why they care. [7][8] If a kitchen offers you new oil they never used, do not put it in the UCO tank.
Theft claims fail when you have no seal log. They also fail when three collectors share an unlocked pad. One lock per bin. Your lock.
Invoices and scale tickets belong in the same folder as the business license and the DNREC email. Yellow grease work is boring when the file is complete. It is ugly when it is not.
If you want another state's cost stack for the same file-building habit, yellow grease cost in Florida and yellow grease cost in Colorado are fair reads. Different boards. Same need for receipts.
What is a waste of money in year one in Delaware?
A new vacuum truck is the classic waste. So is paying a consultant for a Delaware yellow grease license packet that is just a business license you could have filed yourself. So is buying 200 bins before you have 30 weekly stops.
I would start with fewer, better New Castle accounts and a used truck that already passes inspection. Add Sussex only if you can park the extra volume in summer without starving the route in January.
Do not collect interceptor paste to add gallons. You will contaminate a yellow grease tank and eat a rejected load. One rejected tanker costs more than a month of honest fryer oil.
Skipping insurance to see if the route works is how a fender bender ends the company. Skipping the SPCC count because they are just totes is how you meet federal enforcement. [11]
A shiny website does not pick up oil. Call kitchens. Bring a one-page service sheet. Come back when you said you would. Density in a small state beats a map with pins in all three counties and no weekly gallons.
How does yellow grease cost in Delaware compare to other states?
Delaware's cost stack is a USDA-linked commodity price plus ordinary state business paper. It is not California's inedible kitchen grease program. It is not a mystery tax. Compare the paper, more than the cents, before you move a truck across a state line. [1][3]
Nearby, Connecticut is the more useful East Coast read: yellow grease cost in Connecticut. For a huge licensed market, use yellow grease cost in California. Illinois sits closer to the AMS Midwest quote: yellow grease cost in Illinois.
Freight is the silent line. A better USDA print does not help if you are deadheading to a dock three states away with 400 gallons. Density beats posted price.
Confirm every out-of-state license before you cross a border with a loaded tote. Reciprocity is not a feeling. Delaware yellow grease does not become legal in the next state because your LLC is domestic.
How do restaurant FOG rules affect yellow grease supply in Delaware?
Yellow grease, in the trade, is used fryer oil. FOG programs at sewer authorities exist because fats, oils, and grease clog pipes. EPA's pretreatment materials tell cities to control FOG at food service establishments. That is interceptor and plumbing work. It is not your yellow grease route. [10]
City and county sewer systems care about what goes down the drain. They do not set the USDA yellow grease quote. Do not promise a restaurant that your tote pickup satisfies their interceptor pumping schedule. It does not.
If a manager tries to pour trap grease into your bin, say no. Then write it down.
Supply in Delaware follows kitchens, hospitals, and grocery fryers. Campuses around Newark help. Beach fryers help in summer. That is the map. There is no state quota and no state gallon allotment. Anyone selling you a Delaware grease territory license made it up.

Frequently asked questions
Do you need a license for yellow grease in Delaware?
You need a Delaware business license to collect or sell yellow grease as a business. There is no standalone grease-collector card. Confirm with DNREC whether hauling is in scope for a solid waste transporter permit, and ask the Department of Agriculture if you will sell feed-grade fat. Confirm current fees with each board. No one can promise approval.
How much does yellow grease cost in Delaware?
Delaware does not publish a local spot price. Collectors price off the USDA AMS weekly yellow grease quote in cents per pound, then subtract freight and quality. Restaurant pay is private and can be a payment, free pickup, or a service charge. Pull the current AMS sheet before you bid. Nobody has good public restaurant-pay data for the state.
How long does yellow grease take in Delaware?
There is no dedicated grease permit clock. Entity, business license, insurance, and a DNREC answer each take their own time. Confirm current processing with those boards. Do not buy a guaranteed start date. On the route, weekly pickup is the honest quality cycle. Sussex volume is seasonal. Cross-state driving is short. Waiting on kitchens is not.
Is used cooking oil hazardous waste in Delaware?
Straight used fryer oil is usually not federal used oil and is not automatically hazardous waste. Mix it with listed hazardous waste, dump it, or abandon it and the picture changes. Delaware solid waste rules can still apply to how you handle discarded material. Describe your exact flow to DNREC and keep the written answer. Do not guess from a forum thread.
Do I need a DNREC solid waste transporter permit?
Maybe. It depends on whether DNREC treats your loads as solid waste activity under 7 DE Admin. Code 1301. Commodity oil moving to a renderer is often treated differently than discarded waste. Call the solid waste transporter program, describe restaurant to tote to renderer, and confirm in writing. Do not pay a third party who claims they already know your determination.
How many gallons trigger an SPCC plan for yellow grease?
EPA's SPCC rule uses 1,320 gallons of aggregate aboveground oil storage as the common trigger, and 42,000 gallons for completely buried capacity. Animal fats and vegetable oils count as oil. Five 275-gallon totes already exceed 1,320 gallons. Confirm the count in 40 CFR 112. A Delaware collection yard does not get the farm container break.
Do I pay restaurants for fryer oil in Delaware?
Sometimes. When USDA quotes are strong and several collectors are bidding, kitchens get paid. When the print is weak or density is thin, pickup is free or the kitchen pays for service. There is no Delaware posted restaurant rate. Write a formula tied to a public sheet and quality. Handshake pennies turn into angry emails by month three.
What is the difference between yellow grease and brown grease?
Yellow grease is used fryer oil. Brown grease is interceptor or trap material, wet and dirty. Buyers of yellow grease reject trap grease. Sewer FOG programs exist to keep that material out of pipes, not to set your USDA price. Keep the streams in separate containers. One bad pour can reject a whole tank.
Can I start with totes instead of a vacuum truck?
Yes, and that is what I would do on a first-year Delaware route. A used box truck and sealed poly totes will service a small New Castle book. A new vacuum truck adds debt, not legality. Watch the SPCC math. Totes add up fast once you stage them in a yard. Lids and locks matter more than pumps on day one.
Does Delaware have a renderer license for collectors?
Delaware does not run a California-style inedible kitchen grease collector card. You still need ordinary business paper, and you may need DNREC waste determinations. Selling commercial feed fat is a Department of Agriculture question under Title 3, Chapter 17. Confirm each board. Anyone selling a statewide renderer territory license invented it.
How is yellow grease priced per pound?
Publicly, USDA AMS quotes yellow grease in cents per pound on a weekly national sheet. Your check is that basis minus freight, water, MIU, and FFA. EPA RFS demand is why plants care about used cooking oil origin. Delaware has no separate city quote. Read the current AMS report the week you price a route, not a blog average from last year.
What insurance do I need to haul yellow grease in Delaware?
Plan on commercial auto and general liability at a minimum, and talk through pollution coverage with a broker who has written tank or waste accounts in the state. I will not invent a premium. Your driving record, parking, and tank size move the number. Skipping cover to test the route is how one fender bender closes the company.
Is yellow grease theft a real risk in Delaware?
Yes. Used cooking oil theft is a national problem, and Delaware does not need a special statute for stolen oil to be theft of property. Use your own locks, numbered seals, and photos. Do not share unlocked pads with other collectors. A complete seal log is what makes a police report useful. An open bin is an invitation.
Do I need a commercial feed license to sell to a renderer?
Often no, if you are only delivering whole used cooking oil to a renderer as a feedstock. If you process, blend, label, or sell yellow grease as commercial feed fat in Delaware, Title 3, Chapter 17 applies. Confirm with the Department of Agriculture before you print a feed tag. Federal 21 CFR 589 still applies to prohibited proteins. Do not mix mystery fats.
