Renewable natural gas project suppliers are the companies that turn landfill gas or farm biogas into pipeline-quality fuel. There are four kinds: project developers, EPC contractors (engineering, procurement and construction), equipment vendors and O&M providers.
To find the projects they sell into, use two free EPA sources. The Landfill Methane Outreach Program (LMOP) covers landfills, and AgSTAR covers livestock digesters. Then find the few people behind each project who sign.
I look at this from the outbound side. In a small technical market like RNG, a careless list burns the whole market fast. The list is the first thing to get right.
Who supplies a renewable natural gas project?
EPA defines RNG as biogas that has been upgraded so it can replace fossil natural gas (EPA, Renewable Natural Gas). The biogas comes from municipal solid waste landfills. It also comes from digesters at wastewater plants, livestock farms and food or organic waste sites.
Raw landfill gas is only about half methane (EPA LMOP, key information). Getting it to pipeline quality takes a full treatment plant, and four kinds of companies split the work:
| Supplier type | What they do | Who usually hires them | When they matter most |
|---|---|---|---|
| Project developer | Secures the gas source, finances the project, often owns the plant and sells the gas | The landfill or farm owner | Before design starts |
| EPC contractor | Engineers the plant, buys the equipment, builds it | The developer | After the developer commits to build |
| Equipment supplier | Sells gas cleanup, upgrading, compression and monitoring systems | The EPC or the developer | Design and procurement |
| O&M provider | Runs and maintains the plant | The developer or the owner | From commissioning onward, for years |
Read the hiring column before you build a list. A compressor vendor writing to a landfill owner is usually writing to someone who never buys compressors. The developer or the EPC does. Owners can use the column in reverse. If you hold a gas source and do not want to finance or run a plant, look for a developer first. The developer hires everyone else.
Farm projects add a step. A landfill already makes gas as buried waste breaks down. A farm usually needs a digester built before there is any gas to upgrade. So on a farm, the decision sits with the farm owner and a digester developer.
Where are RNG projects listed?
For landfills, start with LMOP. EPA reports that landfills in 48 states and 1 U.S. territory supply gas for electricity, heat, pipeline-quality gas or vehicle fuel (EPA LMOP). For farms, AgSTAR, which EPA runs with USDA, keeps the digester list. The resources below are the starting set:
| Resource | Question it answers | What you get | Watch out for |
|---|---|---|---|
| LMOP home page | How is a landfill gas project planned and bought? | Project Development Handbook, Example Procurement Files, a national map of landfill gas energy projects | No supplier rankings or comparisons |
| LMOP project data | Which landfill projects exist, and of what type and state? | Project name, type, state, status, capacity and, per EPA's field list, developer and end user | Confirm which columns the file you download carries |
| LMOP Landfill and Project Database | What stage is each project at? | Planned, under-construction, operational and shut-down projects | Files are refreshed periodically, so check the date |
| AgSTAR | How are farm digester projects planned and run? | Project Development Handbook, AD/Biogas System Operator Guidebook, a Vendor Directory, the digester database | Guides and a vendor list; the project list is the next row |
| AgSTAR livestock digester database | Which U.S. livestock farms run digesters? | Map and table of operating projects, plus an Excel file adding under-construction and shut-down ones; data through June 2024, updated about twice a year | Voluntary sources: not exhaustive, and EPA does not guarantee accuracy |
Which list you open first depends on what you sell. Project stage is the sales signal that matters most:
- Equipment or engineering: start with planned and under-construction projects. Operating plants already bought their main equipment.
- O&M, service or parts: start with operating projects and the ones close to start-up.
If the download names a developer, sort by that column. A developer that appears on several rows runs several sites, so it goes to the top of your research list.
EPC firms that also bid civil work can apply the same stage logic to construction project leads data. If your equipment also goes into hydrogen plants, the guide to hydrogen project suppliers explains who supplies those projects and where they are published.
Should you start with landfills or livestock digesters?
Start where you can name a real site. If your past projects were farm digesters, open AgSTAR first. If they were landfill plants, open LMOP first.
Before I open either database, I look at who already paid the supplier and for which projects. Then I search for sites and developers that resemble them. Take a service company that maintains two pipeline-injection plants. It should start with pipeline-injection projects, because its proof fits them on the first read.
If you have references in neither segment, pick the one where your product changes least. Then say in your messages that the segment is new for you. Keep landfill and farm targets in separate lists and campaigns, because the buyers, their vocabulary and the proof they want all differ.
Who signs, and how do you reach them?
My first question to any supplier is simple: who signed the purchase order on your last few projects? That title steers the list better than any lead tool's suggestion.
Titles vary. At an LMOP webinar on November 12, 2024, three people presented a landfill RNG project in Corpus Christi (4,000 standard cubic feet of gas per minute, or scfm). They were the city's assistant director of solid waste, the developer's owner and its VP of operations. A 1,000 scfm project in New York came from a county assistant commissioner and a project development director (EPA LMOP webinar).
That matches how EPA describes these projects. EPA's LFG Energy Project Development Handbook says landfill owners, energy service providers, end users and state and local government representatives work together to develop them. It does not name one title that signs the EPC or equipment order. So plan for a group of buyers, not one.
Use these as a starting set and test them against your own deals:
| Target company | Titles to test first |
|---|---|
| Developer | Owner at smaller developers, VP of development, VP or director of operations, project development director |
| EPC contractor | Estimator, procurement lead, project manager on energy jobs |
| Public landfill owner | Solid waste director, assistant director of solid waste, landfill gas or environmental lead |
| Farm with a digester | Owner, operations lead |
I remove bare titles like Assistant, Manager and Associate from every search. Public owners need care, though. An assistant director there can be the person presenting the project, so filter only the bare word.
Size changes the plan. In a broad B2B market, I want a first list of 20,000 contacts or more. RNG is far smaller. EPA counted 102 landfill RNG projects and 135 farm RNG projects operating in 2023 (EPA, Renewable Natural Gas), so the list runs out fast.
Add every stage and it is still small. Biomass Magazine, reporting RNG Coalition figures, counts 505 operational U.S. facilities, 153 under construction and 293 in planning. That is under 1,000 sites in total. Go deep: several people per company, a message written for each role, and no general energy companies added to make the list look bigger.
Build the list with LinkedIn Sales Navigator, Apollo, UpLead, ZoomInfo and RocketReach. Run every address through NeverBounce or DeBounce and keep bounces under 0.5%.
Skip cheap freelancer lists. With this few developers, a bounced first email is a first impression you may not get back. Give each account one owner on your team, so two reps never write to the same developer. Finding the right contacts for cold email and our lists and targeting FAQ cover the mechanics.
What should the outreach say?
The opening message asks for a short meeting. Pitching in the first touch is the fastest way to get ignored. Mention the buyer's own project instead.
I make the LinkedIn touch first, and the warm email follows it. Plan at least 5 to 6 touches over several weeks across both channels. The follow-up that works is usually the third. Give it room, and do not stop after two.
Everyone sending needs a LinkedIn profile that shows the company and its RNG sites, because a developer checks before answering. Treat the profile as part of the pitch.
A made-up example from a fictional O&M provider to a developer's director of operations:
Subject: Who operates Riverbend after start-up?
Hi Maria, I saw Riverbend listed as under construction for pipeline injection. We operate two landfill RNG plants that inject into the pipeline, and we can be in place before commissioning. If the operator decision is still open, would a 20-minute call be useful?
A good first message names one project and one proof line, then asks one small question. Later messages carry different proof from your own record: site type, scope, outcome.
Answer every reply the same day, and put one person in charge of the inbox so nothing gets missed. A "talk to me after commissioning" is a real lead, so log it in your CRM with a date and come back on time.
What should a project owner ask suppliers?
For a landfill project, start from LMOP's Example Procurement Files and its Project Development Handbook. For a farm project, start from AgSTAR's handbook, and check its Vendor Directory for names to shortlist. Then add questions that separate a sales pitch from real delivery capacity:
| Question | Strong answer | Warning sign |
|---|---|---|
| Which of the four roles do you cover in-house, and what do you subcontract? | Named roles and named subcontractors | "We do everything" |
| Which projects did you work on, and in what role? | Named sites you can check in LMOP or AgSTAR data or public announcements | Logos with no project names |
| Which feedstock have you handled? | Specific landfill and manure sites | One feedstock presented as both |
| What timeline do you assume, and from which stage? | Dates tied to the stage, plus what the owner must supply | One timeline for every project |
| Who will work on our site, during and after start-up? | Names, roles and an O&M or handover plan | Only a sales contact |
One trap shows up on both sides. Some owners ask shortlisted suppliers for weeks of free design work. I never ask anyone to work for free. I would be wary of any vendor that offers weeks of unpaid engineering to win a deal. Pay your top two candidates for a small study and judge what they deliver.
Suppliers can head off that request by building proof once. Write case studies with real numbers and timeframes, and record a short video sales letter on how you deliver.

Questions buyers and suppliers ask about RNG projects
Are wastewater and food waste digesters in the LMOP or AgSTAR data?
EPA names wastewater plants and food or organic waste operations as biogas sources for RNG. But LMOP's data covers landfills, and AgSTAR's database covers livestock farms. A supplier selling into wastewater or food waste digesters needs its own list, built from past projects, public project announcements and the companies or agencies that own those sites.
How current is the LMOP database?
EPA says LMOP generally publishes updated database files two to three times a year (EPA LMOP database). The composite file on that page carried a September 2024 date when I checked. So look for a newer download, and confirm each project's stage against its own announcements before you write.
Does EPA publish supplier prices for RNG projects?
None of the EPA pages listed above publishes supplier prices or fee ranges. For a rough landfill project cost, owners can run LFGcost-Web, EPA's estimating tool linked from the LMOP home page. Use it to sanity-check bids. You still need quotes from shortlisted suppliers to compare real prices.
Is intent data worth buying for RNG prospecting?
Usually not. Intent data flags companies reading about a topic online, and it pays off when a market runs into many thousands of companies. In a small market, say 600 target companies, signals may show up on only a handful. Everyone on the EPA lists already has a biogas project, so build an offer that fits all of them.
How long before outreach to RNG developers turns into contracts?
Meetings can come in the first 30 days after launch. The contracts from them may close 4 months or more later, and a typical B2B deal takes 6 to 12 months.
Judge month one on conversations and on which titles reply. Give the campaign at least 3 months. One tech client of ours went from zero qualified calls booked to 40+ per month in 90 days. Then scale only what already gets replies.
