A procurement reference for hyperscale data center operators, EPC contractors, and ESG diligence teams building in Michigan. Prepared by Michigan Farm Waste Exchange, Greenville, MI.
Michigan's lower peninsula produces roughly 2.06 million acres of corn and 2.02 million acres of soybeans annually. The majority of harvest residue — corn stover, bean trash, wheat straw — is currently disked back into the field. A sustainable portion of this material (typically 30–50% removable depending on soil type) represents an annual, locally-sourced biomass feedstock pool measured in the high six figures of tons within a 100-mile radius of every announced Michigan data center site.
Michigan Farm Waste Exchange aggregates this supply at the farm level and matches it to operators, EPCs, and biomass processors who need verifiable, low-carbon process inputs for cooling-system support, on-site combined heat and power, or scope-3 ESG reporting. We do not bale, haul, or process. We hold the relationships, the data, and the contracts.
This document is a procurement reference, not marketing material. Sections 3 through 6 describe what we can supply today, what we are still building, and the contracting model under which we engage. Section 7 discloses what we will not claim until we have audit-grade data behind it.
1. Locality. Every announced Michigan hyperscale data center site is within 100 miles of significant corn-stover-producing acreage. Greenville (our base) sits roughly 60 miles north-northwest of Lyon Township and 90 miles northwest of Saline Township. Lake Odessa, our second pilot, is 60 miles from Saline directly. Average feedstock haul distances for participating buyers should range from 30–80 miles.
2. Sustainability documentation. Sourcing agricultural residue at sustainable removal rates avoids the soil-depletion arguments that complicate purpose-grown energy crops. It also avoids the deforestation arguments that complicate wood pellet imports from the southeastern US [2]. The carbon accounting is favorable: corn stover absorbed CO₂ during the growing season; residue that decays anaerobically in-field releases CH₄ (≈80× more potent than CO₂ over 20 years) [3]. Captured residue is a net win on both gases.
3. Political license to operate. The Michigan data center debate is publicly contested in 2026. The Michigan Attorney General has intervened in the DTE/Stargate power contract case [4]. Residents in Saline and Lyon Townships have organized. Procurement narratives that include verified local-farmer participation directly address the loudest objection — that data centers extract from rural Michigan without giving back. A farmer-paid feedstock chain is the cleanest answer available to that objection.
| Feedstock | Typical removable yield | Harvest window | Notes |
|---|---|---|---|
| Corn stover | 1.5–2.5 tn/ac | Oct–Dec | Primary feedstock. Best baling window depends on weather; storage required for off-season delivery. |
| Soybean residue | 0.5–1.0 tn/ac | Sept–Nov | Lower yield, faster degradation. Often blended with stover for pellet-grade applications. |
| Wheat straw | 1.0–1.8 tn/ac | Jul–Aug | Smaller pool in Michigan but valuable for off-season delivery scheduling. |
| Cover crop biomass | 0.3–1.5 tn/ac | Spring | Variable. Increasingly available as Michigan cover-crop adoption grows. |
MFWE's enrollment is starting in two pilot zones in West Michigan, both selected for high corn density and reasonable haul distance to announced data center sites:
| Pilot zone | County | Distance to Stargate Michigan (Saline Twp) | Distance to Verrus (Lyon Twp) |
|---|---|---|---|
| Greenville | Montcalm | ~90 mi | ~65 mi |
| Lake Odessa | Ionia | ~60 mi | ~55 mi |
Both zones sit inside the realistic biomass haul radius for combined heat and power applications (generally 50–100 miles, beyond which pelletizing and densification become economically necessary). Expansion priority counties — Kent, Ottawa, Allegan, Eaton, Calhoun — extend the network deeper into the announced data center corridor running from Ann Arbor west toward Lansing and Grand Rapids.
Hyperscale operators face growing pressure on Water Usage Effectiveness (WUE), Carbon Usage Effectiveness (CUE), and increasingly granular scope-3 supply chain disclosure. We're building the documentation chain to feed those reporting frameworks:
MFWE is positioned as an introduction and aggregation layer, not a logistics or processing company. Our role today is to connect buyers to verified farmers and to provide the documentation chain that supports ESG and procurement reporting. We do not bale, haul, store, or process feedstock — those services are arranged between the buyer and existing regional contractors, on terms the buyer controls.
Engagement options:
Standard engagement under any option includes a mutual NDA and a non-circumvention clause covering 18 months from introduction date. This protects both sides: farmers don't get cherry-picked out of the network, and operators don't get poached by competing buyers we've introduced them to.
If you're a procurement or diligence professional, you've read documents like this before. Most of them oversell. Here's what's actually true about Michigan Farm Waste Exchange in May 2026:
The investment thesis we're working from is that the residue supply chain in Michigan needs an aggregator, and that the political and ESG environment in 2026 specifically rewards local, transparent, farmer-paid sourcing. We think we can be that aggregator. We don't claim to be it yet.
If you're sourcing biomass into a Michigan project — or weighing one — we'd rather meet you at the diligence stage than at the contract stage. Quieter, more useful, and there's still time for the relationships to actually mean something at your permit hearing.
