To sell to an ethanol plant, pick one plant segment, find the 2 or 3 people at each plant whose work your product changes, and reach them on LinkedIn before email with one result from a comparable plant.
This guide is for suppliers: equipment makers, repair shops, lab and software vendors, engineering contractors. It is not about selling corn to a plant or buying ethanol from one. This is how I would build a plant campaign.
Which biofuel plant segment should you target first?
Fuel ethanol is the biggest segment. In 2022, the latest year on EIA's biofuels explainer, it made up 82% of US biofuel production, out of about 18.7 billion gallons of biofuels produced (EIA, 2022 data in a table dated February 2024).
The plant counts are fresher. EIA's capacity report lists 189 operable US fuel ethanol plants as of January 1, 2026, with combined capacity of 1,202 thousand barrels per day. It also counts 45 biodiesel plants and 19 renewable diesel and other biofuels plants, a group that includes renewable jet fuel (EIA).
Let your own order history pick the segment. Note who bought from you last year and who signed each order. If most of it came from ethanol producers, your first list is ethanol, because your references and your vocabulary already fit that buyer. If the history points nowhere, start with fuel ethanol, which has by far the most plants. Run one segment for 90 days before adding another.
| Segment | Lead with it if | Proof that carries over |
|---|---|---|
| Fuel ethanol | Most past plant orders were ethanol | A result at a comparable ethanol plant |
| Biodiesel | Your product handles oils, fats or their byproducts | A biodiesel reference; ethanol proof is weaker here |
| Renewable diesel | You already sell to large process plants | References from big process sites |
| Sustainable aviation fuel (SAF) | You can wait out a long road from first call to order | Your closest process reference; confirm the plant is producing |
Who decides at an ethanol plant?
That depends on what you sell, so work it out from your closed deals. For each one, write down who signed, who evaluated and who could have blocked it. Then search for those exact titles. A plain "manager" tells you nothing, and I strip Assistant, Associate and bare Manager out of every list I build.
Before you have deals, job listings give you a starting point. A plant job listing on the Ethanol Producer Magazine job board has the Maintenance Manager oversee purchasing of parts and supplies and the spare parts inventory. The same role helps develop the annual repair, maintenance and capital expenditure budgets. If you sell parts or repair work, test that title first.
Titles to test by product, as a first guess until your own deals show the real signers:
| What you sell | Titles to test first | Likely sign-off |
|---|---|---|
| Spare parts, pumps, valves, rebuilds | Maintenance manager, reliability engineer | Plant manager |
| Process chemicals and additives | Process engineer, production manager | Plant manager or general manager |
| Lab, testing and compliance tools | Lab manager, quality manager, EHS (environment, health and safety) manager | General manager or CFO |
| Feedstock, grain logistics, rail | Commodity manager, grain merchandiser | General manager |
| Engineering and expansion work | Plant manager, project engineer | CEO or general manager |
Write to the daily user and the likely signer in the same week, with a different message for each. Add the purchasing lead third where a plant has one. Purchasing often handles vendor setup and terms, so check in your own deals whether they started the search or only signed off. Skip shift operators, assistants and HR.
How do you build a list of ethanol plants and contacts?
EIA's plant-level capacity file is your coverage map. Each row is one plant with its capacity, and there are no names in it. Mark the plants that look like your current customers in size and region. Those lookalikes go to the top.
Fill in the people with proper data tools such as ZoomInfo, Apollo, Sales Navigator, UpLead or RocketReach. Cheap freelancer lists bring low opens and high bounces. Run every address through NeverBounce or DeBounce before the first send and stop the campaign if bounces climb above 0.5%. Our lists and targeting FAQ goes deeper on sourcing.
Do the math: 3 people at every fuel ethanol plant on the EIA list is under 570 contacts. That is not a volume play. Don't try to make it one. If it does not convert on 50 contacts, it will not convert on 500.
Give every row these fields:
- Segment and state
- Capacity band from the EIA file
- Single plant or part of a group
- At least 2 real titles
- One owning rep
Split plants between reps so no plant hears from two people at your company. Any CRM works, as long as no reply gets lost.
Which buying signals tell you when to write?
Watch the federal calendar. EPA sets annual volume requirements for four categories of renewable fuel through rulemaking, and for years after 2022 it must set them at least 14 months ahead (EPA). When new volumes are final, owners have fresh numbers to plan against. If you sell expansion or efficiency work, that is your reason to write.
EPA's final standards keep the conventional biofuel level, the category that covers corn ethanol, at 15 billion gallons for both years. The Federal Register notice says EPA partly reallocated exempted volumes so the 2023-2025 exemptions would not significantly hurt biofuel demand in 2026 and 2027. For a supplier, that means owners know the conventional volume they are planning against for 2026 and 2027.
Compliance risk is a second reason to write. Renewable fuel producers and importers generate credits called Renewable Identification Numbers (RINs), and EPA pursues enforcement against producers that generated invalid ones (EPA). If you sell measurement, lab, data or compliance work, put that risk in your message.
Plant events decide who goes into this month's batch:
- An expansion or new process announced
- A new plant manager or maintenance lead
- A planned shutdown or turnaround
- A change of owner
The shutdown signal is the easiest to time. Ethanol Producer Magazine reports that plants commonly schedule 2 shutdowns a year: spring (April or May) and fall (October). Some run 1. Golden Grain Energy in Iowa takes 5 to 8 days each year for preventative maintenance, repairs and new technology installs. Reach out before that window, not during it.
Plants with no signal still get a message. Just later, and less often.
What should the first message say?
Ask for a short call and save the full offer for later. A stranger cannot judge your service yet, so the reply comes from proof: one real result from a comparable plant, inside the email. Fifteen minutes away from a running plant costs them something, so say what they walk away with.
A made-up example from a centrifuge repair shop:
Subject: decanter rebuild ahead of your next turnaround
Hi Jordan, I saw you lead maintenance at an ethanol plant in Iowa. My shop rebuilds decanter centrifuges for plants in Iowa and Nebraska, and at one Nebraska plant we turned 2 decanters around inside a 4-day shutdown. If a rebuild is on your list before the next one, would 15 minutes next week be useful? I'll bring the turnaround plan we used so you can compare it with yours.
Then run the delete pass: any line that does not earn the reply goes before you hit send.
Should you start with LinkedIn or cold email?
Start on LinkedIn. In B2B, nobody buys from an email. They look you up first, and a name they already saw in a connection request reads warmer when it reaches the inbox. I never let email be the first touch.
One message got 2% replies at one company. At another it got 7.5%. The difference was the sender.
Budget five or six touches over email and LinkedIn. Don't stop after touch 2. Replies in our campaigns usually come on the third follow-up. That only happens if you leave real gaps between touches.
| Touch | Channel | Its job |
|---|---|---|
| 1 | Connection request naming their segment, no pitch | |
| 2 | Short note with your reason for reaching out | |
| 3 | The first message: proof and a small ask | |
| 4 | A new angle, such as a different result | |
| 5 | Brief nudge referring to the email | |
| 6 | Close the loop with something useful, like a checklist |
Send to the signal plants first and read every reply. If that batch does not turn into conversations, fix the list or the offer before sending more. A neighboring process industry has the same small-market problem and different buyers. Chemical plants are one example, and manufacturing outbound more broadly follows the same pattern of short lists and long cycles. The same method also runs for industrial and manufacturing companies.
Your first 90 days: one segment, a few hundred names researched by hand, every reply read. Fix the funnel first. Then scale. Suppliers whose product also fits food manufacturing plants can reuse the method with a different buyer list.
Selling to ethanol or biofuel plants and unsure which titles to test first? Talk it through on a call and I will share what I would try.
Questions suppliers ask about selling to ethanol plants
How long does it take to go from a first meeting to a purchase order?
Longer than your first quarter's forecast. Plant buying is slow: a meeting from month one may turn into a purchase order four months later, or more, once budgets, site approvals and turnaround dates line up. Plan for sales cycles of 6 to 12 months. Judge the early months on conversations and meetings, and judge revenue on a much longer clock.
What should a supplier have ready before contacting a plant?
A one-page capability sheet, a case study from a comparable plant with real numbers, and the safety and insurance documents a plant is likely to ask for before anyone works on site. Ask your best customers which ones they were asked for.
Some plants check this through a prequalification platform. ISNetworld collects and reviews supplier certificates, Workers' Compensation and financial information. Its review team checks what contractors and suppliers submit against regulatory and Hiring Client requirements.
Line up one current customer who has agreed to take a reference call, so you can say yes the day a plant asks to speak with someone who already uses you.
What changes when a plant belongs to a multi-plant group?
In some groups, site staff evaluate and corporate operations or procurement approve vendors for every plant; in others the site decides. Check which way your target group works. Write to both levels with different messages: practical detail for the site, a group-wide view for corporate. Give the whole group one owner on your side so the parent company hears one consistent voice.
How much sending setup does a small plant list need?
The same as a big one. Set up SPF, DKIM and DMARC on every new domain first. Then warm each inbox for 10 to 14 days at minimum, and only after that add volume. Our deliverability FAQ covers the setup.
Does this approach work for plants in the UK or Europe?
The method carries over, but the data does not: EIA and EPA cover only the US, so you need another plant list. Email rules differ too, and the UK and each EU country set their own. Without a compliant basis, skip cold email in Germany, Austria and Czechia and go through LinkedIn. This is not legal advice.
