Research draft. Not legal, tax or financial advice. Figures are dated to their sources; placeholder assumptions are flagged as such.
Option A: Kill-Only Mobile Unit + Partner Cut Shop
Status: superseded (rounds 1-2 recommendation; replaced by Option B: Cooler-Dock Kill-and-Cut in round 3). Kept so the reasoning stays visible. All options: Business Model Options. Not legal advice.
How it works
- A custom-exempt kill-only trailer goes to the owner’s farm: stun, bleed, skin, eviscerate in the field.
- Offal stays on that farm (composted) or is tubbed for the renderer.
- Sides or quarters ride in the trailer’s cooler to a partner cut shop (custom-exempt or USDA plant), which hangs, cuts and packs.
- The owner picks up at the partner shop.
Legal basis
- Free VDACS Custom Permit for the operator, renewed each June 30. Product is the owner’s, marked “Not for Sale” (VDACS).
- The partner shop must itself be able to take custom-exempt carcasses (its own Custom Permit or custom segregation inside an inspected plant).
- See Regulatory Models Compared.
Zoning and site (Frederick County)
- No fixed processing site. The rig only needs a yard to park and wash.
- Open for all options: whether a mobile unit killing on RA farms is itself a “slaughterhouse” use. The RA definition says “establishments primarily engaged in the slaughtering or processing of meats”, and its explicit exception covers only farmers killing their own animals for family use (RA zoning). Needs a Zoning Administrator determination.
Waste
- Offal: composting on the farm of kill is likely exempt under 9VAC20-81-95 D.4 (DEQ).
- Blood and kill-floor wash water are DEQ “industrial wastes” (VPA): capture blood on the rig.
- No cutting waste: that lands at the partner shop.
- Detail: Slaughter Waste Disposal in Virginia.
Capacity and labor
- Kill labor: about 7 beef per person per 8-hour day (NMPAN/Lorentz 2010) (NMPAN costing).
- The real limit is partner cut-shop slots. Regional plants ran 125-150% of capacity and every one reported a cutter shortage (PEC 2021) (PEC).
Economics
| Line | Value | Source |
|---|---|---|
| Rig capex | $72k (12 ft) / $92k / $115k, “starting at” | Sentinel 2026 list (Sentinel) |
| Revenue per head | Kill fee only: $100-150/head + $2.65/mi + $500/day minimum (Backyard Butchery OK, 2025); fixed-plant kill fee $75 (T&E 2025) | farm-kill table, Valley prices |
| Capital recovery | About $44/head at 300 head/yr on a $92k rig over 7 years, before interest [inferred] | Custom-Exempt Mobile Rig |
The cutting revenue ($0.90-1.05/lb, the bulk of a beef’s processing bill) goes to the partner, not the operator.
What it fixes
- Lowest capex of any option; no fixed site, no cooler, no cutting labor to hire.
- No processing-site zoning question.
What it costs
- It feeds the bottleneck instead of relieving it. Owners still wait for cut-shop slots.
- Precedent: California’s Central Coast mobile unit sat idle about 2 years with no reliable hanging and cutting partner (Central Coast).
- Thin revenue per head; the business lives on a kill fee plus minimums.
Open questions
- Will any Valley cut shop commit cooler space and slots to a mobile kill partner? (Not tested.)
- RA “slaughterhouse” determination for farm kills (shared with all options).
Verdict
Superseded. Cheap, but it does not shorten anyone’s wait while cutters and cooler space are the binding constraint. Its one live use is as a component: the kill trailer could pair with a separately sited cut room (noted in Mobile Beef Processing Business Plan).
