TL;DR
Delaware does not issue a dedicated yellow grease collector license. File a state business license with the Division of Revenue, form your entity if you want one, and ask DNREC whether your loads count as solid waste. USDOT and SPCC rules can apply by truck weight and tank size. Confirm every current fee and timeline with the board that issues the paper.
Do you need a license for yellow grease in Delaware?
Delaware does not issue a standalone yellow grease collector license. You still need a Delaware business license from the Division of Revenue if you do business in the state, and you may need DNREC permission if the state treats your pickups as solid waste collection or transport. Entity formation is separate paper and is not a grease permit.
That is the whole plot. People want one grease card number. Delaware does not sell that product.
Title 30, Chapter 23 is the occupational and business license statute. It requires a proper state license before you carry on listed businesses and occupations. Used cooking oil collection usually lands in a general or wholesale type class, not a named grease line. Confirm the class with Revenue before you pay. Wrong class means wrong gross receipts treatment later. [1][2]
If you form a Delaware LLC, you file a certificate of formation with the Division of Corporations under 6 Del. C. § 18-201. That filing creates the company. It does not authorize restaurant pickups and it does not replace the Revenue license. [3]
Some towns add a municipal business license. Zoning for a storage yard is not a license, but a bad site can stop you before the first drum moves. Call the county or city where the yard will sit, not a Facebook group.
Other states actually license this trade by name. The yellow grease license in California path is not Delaware's path. Neither is the yellow grease license in Texas. Steal the habit of reading the statute. Do not steal the checklist.
I would not pay a fixer who cannot point to Title 30 and 7 Del. C. § 6003. Start with Revenue, Corporations, and DNREC Solid and Hazardous Waste. Ask each office what they want in writing.
How much does yellow grease cost in Delaware?
Startup cost is mostly the truck, bins, insurance, and idle time, not a magic Delaware grease fee. State paper is the cheap part if you classify it right. The Division of Corporations publishes an LLC certificate of formation fee of $90 on its fee schedule. Confirm that figure on the fee page before you file, because published amounts change by statute or schedule update. [4]
The Division of Revenue business license tax sits in Title 30. The dollar amount depends on the occupation line they assign you. I will not quote a stale license tax as if it were today's invoice. Read the current Title 30 line and Revenue's business license tax page, then pay that amount. Gross receipts tax may apply on receipts after you start selling. Rate and exclusions depend on class. Confirm with Revenue. [1][2]
An EIN from the IRS is free. That is one of the few honest free steps. [11]
The truck is where people light money on fire. A used, legal straight truck that can haul sealed totes will open a small route. A brand new purpose-built vacuum truck for fifteen stops is a vanity buy. Get three used quotes and a mechanic's inspection. I cannot give you a single Delaware sticker price because there is not one.
Bins and locks are cheaper than a stolen weekend. Unlocked open drums are how product walks. Budget for lockable containers and written bin terms with each kitchen.
Insurance will likely beat your state paper cost in month one. Commercial auto is the bill that matters. Add general liability. Ask a broker who already writes waste or food-service haulers about pollution coverage if you store oil at a yard. Nobody publishes a trustworthy public premium table for yellow grease delaware routes, so treat any number you see on a forum as entertainment.
Commodity price is a different question. You usually get paid for grease, or you trade service for oil, depending on how tight the local renderer market is. USDA Agricultural Marketing Service posts weekly energy and grease market news. Use that tape. Do not use a blog's leftover 2022 spike as your pro forma. [12]
Storage can create a sudden professional-engineer bill. 40 CFR 112.1 uses a 1,320 gallon aboveground oil storage threshold for SPCC plans. Cross it and the compliance cost jumps. Stay under it on purpose in year one if you can. [7]
How long does yellow grease take in Delaware?
Paper can move in days or a few weeks if your file is clean. The route takes longer. Delaware does not publish a guaranteed processing time for a grease business because it does not run a grease license queue. Confirm current turnaround with each office. No one can honestly promise you an approval date.
Entity filings with the Division of Corporations are often quick by national standards. That is a reputation, not a clock I will print. Ask Corporations for the current standard and expedited options before you plan a launch party. [3][4]
The Revenue business license is its own line. File through the state's business channels and wait for the license they actually issue. Do not start door-to-door pickups on a submitted-but-unissued application unless Revenue tells you that is allowed for your class. [2]
USDOT registration, if you need it, is a federal online process. Timing is usually short when the form is complete, and it is still not a promise. DNREC review, if they decide your activity needs a solid waste related permit, can take longer than the company filing. Ask the Solid and Hazardous Waste staff what a complete transporter or activity file looks like. [5][6][10]
Landing kitchens is the slow part. A first courtesy pickup can happen as soon as you have legal paper, a place to take the oil, and a container the restaurant will tolerate. A weekly loop that covers truck, insurance, and your time is a sales job. It can take months. Nobody has good public data on Delaware ramp time. The closest honest method is to count signed accounts, not hopeful maps.
If you already haul in another state, read that state's guide separately. How to start yellow grease in Texas will not shorten Delaware's Revenue step.
What paper should you file first in Delaware?
File the entity (if you want limited liability), then the EIN, then the Delaware business license. Parallel-track the renderer outlet and the yard or parking plan so you are not licensed into a dead end.
A sole proprietorship can skip the LLC filing. You still need the Revenue license to do business. You also put your house behind the truck if something goes wrong. I would form the LLC if this is more than a weekend experiment, then keep the books boring. [2][3]
Delaware Division of Corporations lists current formation fees on its fee schedule. Use that page, not a third-party incorporator upsell. Registered agent service is required for a Delaware entity. That is a real recurring cost. Confirm agent rules on the Corporations site. [4]
Get the EIN online from the IRS after the entity exists (or in your own name if you stay sole prop). Free. Print the confirmation. [11]
Then hit Revenue for the business license and ask how they want yellow grease or used cooking oil resale coded. If they hesitate, describe the activity in plain words: collect used kitchen oil, sell it to a renderer or biodiesel plant. Do not let a clerk map you onto a food establishment license you do not need. [2]
Open the renderer conversation the same week. A license with nowhere to dump a full tote is a paperweight. Ask for their incoming spec, hours, and whether they issue the weight ticket.
If you will keep more than a couple of small totes at a yard, skip ahead to the SPCC math before you buy tanks. [7]
Is restaurant oil solid waste or a commodity in Delaware?
It depends on whether the oil is discarded or sold as a feedstock, and DNREC gets the close call. 7 Del. C. § 6003 requires a Secretary permit before you undertake activity "in a way which may cause or contribute to the collection, transportation, storage, processing, or disposal of solid wastes." That sentence is why you ask, not assume. [5]
7 DE Admin. Code 1301 is the Regulations Governing Solid Waste. Definitions and exclusions live there. Source-separated material that is headed to legitimate recycling is often treated differently than trash headed to a landfill. Used cooking oil sold on a ticket to a renderer is usually argued as a commodity. Argument is not a permit. Email DNREC Solid and Hazardous Waste with your fact pattern and keep the reply. [6]
Federal used-oil rules will not save you and they will not automatically bury you. 40 CFR 279.1 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." Straight restaurant fryer oil is not that definition. Mix it with motor oil or hazardous waste and you have a different day. [9]
I would run clean UCO only. Separate truck, separate totes, no shop drains. If a kitchen wants you to take trap grease, interceptor waste, or brown grease, stop and ask DNREC and your renderer before you say yes. That stream is not the same product and it is where people wander into wastewater and solid waste trouble.
Keep bills of lading, weights, and the renderer contract. If someone later claims you were hauling discarded waste, paper is how you show a sale.
What truck and USDOT rules apply to a Delaware grease route?
If you operate in interstate commerce with a commercial motor vehicle that hits the federal weight trigger, you need a USDOT Number. FMCSA says you must have a USDOT Number for many vehicles used to transport property with a GVWR, GCWR, GVW, or GCW of 10,001 pounds or more. A loaded grease truck clears that line faster than people think. [10]
Stay inside Delaware only and the federal interstate piece may drop out. State motor carrier and registration rules can still apply. Confirm with Delaware DMV and FMCSA using the actual truck card, not a forum poll. I would get the USDOT Number anyway if there is any chance you cross into Maryland, Pennsylvania, or New Jersey. Those borders are close and the habit is cheap compared with a roadside mess.
CDL depends on the vehicle, not the oil. Federal Class B generally covers a single vehicle with a GVWR of 26,001 pounds or more. Plenty of starter grease trucks sit under that. Plenty of vacuum trucks do not. Read the door sticker. If you need a CDL, get the right class and any air-brake endorsement the truck requires. [10]
Placards and hazardous materials registration are not the default for straight used cooking oil. Do not self-placard because it looks serious. Do not ignore HM rules if you start mixing fuels or other regulated stuff onto the same motor.
Keep the truck clean enough that a trooper does not smell a spill story. Leaking totes are how a simple haul becomes a discharge problem under 7 Del. C. § 6003. [5]
When does an EPA SPCC plan apply to grease storage?
An SPCC plan can apply to a Delaware grease yard even though this is vegetable and animal oil, not crankcase oil. 40 CFR 112.2 defines oil to include "fats, oils, or greases of animal, fish, or marine mammal origin; vegetable oils, including oils from seeds, nuts, fruits, or kernels." Kitchen grease counts. [8]
40 CFR 112.1 is the applicability section. The usual aboveground trigger is aggregate oil storage capacity greater than 1,320 gallons, counting containers 55 gallons and larger. Completely buried capacity has a much higher 42,000 gallon figure in the same section. Transportation-related trucks in commerce are a different carve-out than a fixed yard. Read the section against your site sketch. [7]
I would stay under 1,320 gallons of yard storage in year one. Use the renderer's plant as the tank farm. Park fewer, smaller totes. That choice avoids a professional engineer plan until the route actually pays.
If you do cross the line, budget for a real plan, secondary containment, and inspections. A binder you downloaded and never followed is not a plan. EPA can inspect. A spill to a ditch behind a New Castle County shop is how this becomes expensive.
SPCC is federal. DNREC can still care about the same spill under state discharge rules. Build the yard like oil will get out, because it will. [5][7]
How do you actually sell yellow grease from Delaware?
You sell to a renderer or a biodiesel plant that already has outbound markets. You do not need to invent a refinery. Delaware is small. Most volume leaves the state or goes to a Mid-Atlantic plant. Call plants, ask if they take independent collector loads, and get the spec in writing.
Typical buyer tests include free fatty acid, moisture, insolubles, and unsaaponifiables. They will discount or reject a wet, breaded, or trap-grease load. Your job is clean fryer oil, covered containers, and a ticket that matches the tank.
If the plant makes biomass-based diesel, they live under EPA's Renewable Fuel Standard pathways. That is their RIN world more than yours. Do not spend year one trying to become a RIN registrant unless you are actually producing fuel. Read EPA's approved pathways page only so you understand why buyers are picky about feedstock origin. [13]
USDA AMS weekly energy reports are how you check whether the plant's posted number is in the same universe as the broader yellow grease tape. If their number is wildly off, ask why. Basis, quality, and freight explain most of it. [12]
Get paid on documented weight. If you need commercially legal scales at your own yard, that is a Delaware Department of Agriculture weights and measures problem, not a grease-license problem. Most small collectors just use the plant scale and keep copies.
YellowGreasePath puts bin terms, theft language, and renderer intake fields in one $149 Bin + Theft + Renderer Kit. You can also draft that stack with a lawyer and the plant's existing form. Either way, do not haul on a handshake.
What local zoning and restaurant rules trip new collectors?
The kitchen is already under grease interceptor and sewer rules. You are the outlet that keeps fryer oil out of the drain. You are not the health department.
Do not tell an operator you can certify their interceptor. You can offer scheduled fryer-oil pickup and a locked bin. Pretreatment and plumbing stay with the restaurant and the local utility. If a town asks you for a hauler registration to pull interceptor waste, that is a different service. Quote it separately or decline.
Your own yard is the zoning fight. A residential driveway with dripping totes will get you neighbors and then code enforcement. Look for industrial or heavy commercial land, or park at the renderer if they allow it. County planning in New Castle, Kent, and Sussex do not share one script. Bring the site address.
Wilmington and smaller municipalities can want their own business license. Ask before the first invoice. A state Revenue license does not always satisfy a city clerk.
Fire inspectors care about combustible liquids in quantity. If you stack totes against a warehouse wall, expect questions. Answer with the actual gallon count, not a shrug.
If you want a comparison for how another small state handles the first-year mess, how to start yellow grease in Alabama is a useful contrast, not a form you can file here.
What insurance and tax filings matter in year one?
Commercial auto first. General liability second. Workers' compensation if you have employees, because Delaware will not treat that as optional. Unemployment insurance follows the same hire. Confirm current employer registration with the Delaware Department of Labor when the first W-2 person starts. I am not printing a fake UI rate.
Pollution or contractors environmental coverage is the policy people skip until a tote falls off a liftgate. If you store at a yard, ask for it. If you only transload at the plant the same day, tell the broker that fact so you do not buy a tank-farm policy you do not have.
Federal income tax is ordinary business tax. Keep mileage, dump tickets, bin purchases, and renderer settlements. The EIN is the hook those accounts hang on. [11]
Delaware has a business license tax and gross receipts tax system under Title 30 rather than a general statewide sales tax on every retail swipe. Your grease sales may still be taxable receipts under GRT rules for your class. Confirm exemptions and filing frequency with Revenue. Do not assume "Delaware has no sales tax" means you file nothing. [1][2]
If you form a Delaware LLC, budget the state's annual LLC tax as a recurring Corporations bill. Confirm the current amount on the Division of Corporations site when you calendar it. Missing that bill is a beginner own-goal. [4]
I would skip exotic fuel-credit filings in year one unless a CPA who has actually done biodiesel work tells you they apply. Collectors selling crude UCO rarely need that headache.
What is a waste of money when you start in Delaware?
Paying anyone for a "Delaware yellow grease permit" that is not the Revenue license or a DNREC instrument they can name. That product is vapor.
A new six-figure vacuum truck before you have signed density. Rent or buy used until the weekly pounds are real.
A tank farm that shoves you over 1,320 gallons so you can feel like a plant. You just bought an SPCC project. [7]
Route software with a monthly burn that exceeds your first kitchen's monthly oil. A notebook and a map app will run twenty accounts.
National "certification" courses that do not map to Title 30, 7 Del. C. § 6003, or FMCSA. If the syllabus cannot cite those, it is content marketing. [1][5][10]
Copying how to start yellow grease in California or how to start a yellow grease business in Tennessee line for line. Those states built different boards. Useful as contrast. Useless as a filing packet.
Giving kitchens free stainless cathedrals in month one to win the account, then watching a competitor swing the lock. Start with a container you can afford to lose, a contract that says the oil is yours once it hits the bin, and a renderer that will take the load Tuesday.
What would I do in the first 30 days?
Week one, I would pick the entity, file the certificate of formation if I wanted the LLC, get the EIN, and call Revenue with a plain-language description of the work. Same week I would call two renderers and one biodiesel plant and ask whether they take independent Delaware collector loads. [2][3][4][11]
Week two, I would put a legal truck under a shop light, read the GVWR, and decide USDOT and CDL with those numbers, not vibes. I would ask DNREC in writing whether my commodity UCO run needs anything under 7 Del. C. § 6003 and 7 DE Admin. Code 1301. I would not haul interceptor sludge while I waited. [5][6][10]
Week three, I would price insurance and lockable bins. I would draft a one-page pickup term: who owns the oil, who owns the bin, what happens if someone else drains it, moisture rules, and the out if the kitchen contaminates the load.
Week four, I would visit kitchens that already have a bin they hate. I would not blanket-pitch every fryer in New Castle County. I would take one clean load, get a ticket, and see if the plant's pay match the USDA AMS neighborhood. [12]
YellowGreasePath is an independent publisher, not a law firm and not a hauler. Nothing here is a permit. If you want the bin, theft, and renderer stack in one download it is on /start. The statutes and board pages above still do the real work.
If you later expand, read a full state guide before you add a second base. How to start yellow grease in Colorado and how to start yellow grease in Arizona will each change the paper again.
Frequently asked questions
Do you need a license for yellow grease in Delaware?
You need a Delaware business license from the Division of Revenue. There is no separate statewide yellow grease collector card. You may also need DNREC paper if your activity is treated as solid waste collection or transport under 7 Del. C. § 6003. Confirm classification with Revenue and DNREC before you haul.
How much does yellow grease cost in Delaware?
State paper is usually small next to the truck, bins, and commercial auto. The Division of Corporations publishes an LLC certificate of formation fee of $90. Confirm it before you file. Revenue license tax depends on your Title 30 class. Commodity yellow grease prices move weekly on USDA AMS reports, not on a Delaware price board.
How long does yellow grease take in Delaware?
Entity and license filings can be relatively quick, but Delaware publishes no grease-specific clock and nobody should promise you an approval date. Confirm current processing with Corporations, Revenue, and DNREC. Building a route that covers the truck usually takes longer than the paperwork. Count signed kitchens, not calendar myths.
Is used cooking oil the same as EPA used oil?
Usually no. 40 CFR 279.1 defines used oil as oil refined from crude oil, or synthetic oil, that became contaminated through use. Straight fryer oil is a fat or vegetable oil, not that definition. Mix it with petroleum used oil or hazardous waste and the picture changes. Keep streams separate and ask DNREC if you are unsure.
Do I need a CDL to haul yellow grease in Delaware?
Only if the vehicle itself requires one. Federal Class B generally applies to a single vehicle at 26,001 pounds GVWR or more. Many small tote trucks sit under that line. Many vacuum trucks do not. Read the manufacturer weight rating and ask Delaware DMV. Interstate property hauling at 10,001 pounds or more also raises the USDOT Number question with FMCSA.
Can I start as a sole proprietor in Delaware?
Yes. You still need the Division of Revenue business license to do business. You skip the LLC certificate of formation, and you also skip the liability box an LLC is meant to provide. An EIN is still wise. I would not stay a sole prop once a truck, employees, or a rented yard enter the picture.
Do Delaware restaurants have to give you their oil?
No. The oil is their property until a contract says otherwise. Some already have a national collector. Some will trade oil for a locked bin and reliable pickup. Win the account with service and clear ownership terms. Do not drain a competitor's locked container. That is a theft problem, not a sales tactic.
Where do Delaware collectors sell yellow grease?
Most small collectors sell to regional renderers or biodiesel plants. Delaware volume is modest, so the plant may be out of state. Get a written spec, hours, and payment basis before you fill the first tote. EPA RFS pathways matter to the fuel producer. USDA AMS weekly reports help you sanity-check the price they offer.
Do I need an SPCC plan for a few totes?
Maybe not. 40 CFR 112.1 generally cares when aggregate aboveground oil storage capacity exceeds 1,320 gallons, counting containers 55 gallons and larger. A couple of small totes under that line often stay out. Add tanks without doing the math and you can trip the rule. Vegetable and animal oils count as oil under 40 CFR 112.2.
Is grease theft its own crime in Delaware?
Delaware treats stolen oil like other stolen property under the ordinary theft statutes. There is not a well-known standalone "yellow grease theft license plate" program at the state level. Use contracts that say you own the oil in the bin, use locks, and call local police if a tank is drained. Photograph seals and keep pickup logs.
Do I need a food-service permit to collect fryer oil?
Not for simple off-site collection of used oil you do not process as food. You are not opening a restaurant. Do not take over their interceptor pumping unless you are set up for that waste stream and the local utility allows it. If you ever process oil into a food or feed product, stop and talk to the agencies that actually regulate food and feed.
Can one truck run Delaware, Maryland, and Pennsylvania?
The truck can physically cross those lines. The paper multiplies. Interstate commerce and the 10,001 pound FMCSA threshold are the first federal check. Then each state has its own business tax and waste questions. Get the USDOT Number sorted and ask each environmental agency about UCO before you advertise a tri-state route.
What records should I keep in year one?
Keep the Revenue license, entity documents, EIN letter, renderer contracts, weight tickets, kitchen agreements, bin inventories, insurance certificates, and any DNREC emails about your status. Keep spill and training notes if you store oil. Those files are how you show the oil was a sold commodity and how you answer a tax or roadside question without waving your hands.
