On-Farm Mortality Management
Livestock
Incineration
Done Right
Every livestock operation deals with mortality. How it leaves the farm decides whether it becomes a disease risk. On-site incineration destroys carcasses where they occur, on your schedule, with nothing hauled off the property and nothing left in the ground.
Why Choose Incineration
The Most Reliable Disposal Method for Modern Livestock Operations
When composting takes weeks and rendering trucks require scheduling, incineration delivers results on your timeline, with full biosecurity and documented compliance.
Complete Pathogen Elimination
A dedicated secondary chamber holds combustion gases at sustained high temperature long enough to fully combust. Carcasses are reduced to sterile ash and viruses, bacteria and prions are destroyed on the premises, including AI, PED, PRRS and ASF.
On-Demand, No Scheduling
No waiting for pickup trucks, no composting lag time. Dispose of mortalities within hours of discovery, which matters most during disease events when every hour counts for containment.
Documented Regulatory Compliance
Agricultural incinerators are permitted under state construction permit programs using EPA AP-42 emission factors. BioSec Agriculture provides equipment documentation to support your permit application.
Purpose-Built for Livestock Operations
From sow farms and broiler houses to turkey barns, dairies and beef operations, incineration equipment is sized to match your mortality load and operation type, from small sites to large commercial production.
Biosecurity Stays On-Site
Carcasses never leave the property. No truck entries, no rendering facility contacts, no off-site exposure pathways. Your biosecurity perimeter stays intact from start to finish.
Lower Long-Term Disposal Cost
A one-time equipment investment replaces recurring rendering fees, and the loading equipment stays clean and dry instead of working daily in decomposing material.
What the Research Says
Why Producers Are Moving Mortality Disposal On-Farm
The Dead-Haul Truck Is a Known Vector
A Swine Health Information Center study across 40 wean-to-market farms found that sites using rendering pickup were more likely to have PRRSV, PEDV or PDCoV detected in environmental samples around the dead-animal area, and at higher viral loads, than sites that did not rely on pickup. The same work showed material from the dead-box area can be tracked across the site by vehicles and people. A rendering route visits many farms with one truck. Source: SHIC
Vehicles Carry Disease Between Farms
Modeling from North Carolina State University of nine PRRSV transmission routes identified trucks moving animals, workers and feed as carriers of the virus between farms. Every vehicle that crosses the gate is a biosecurity event. Source: NC State
Burial Depends on Your Soil and Water Table
EPA guidance notes that on-site burial can present contamination risk depending on soil type and distance to water sources, and in some regions it is restricted or not available at all. The same guidance places permitted and mobile incineration units as protective of human health and the environment, in contrast to open burning. Source: US EPA
Composting Takes Time and Management
Composting works when it is built and managed correctly and has the space and carbon material to do it. It also holds carcasses on the farm for weeks while pathogens are inactivated, and turning the pile puts your loader in decomposing material every day.
Outbreak Readiness
USDA APHIS is the lead federal agency for large-scale animal disease outbreaks, and its own carcass management planning tools compare on-site and off-site options by time and cost. During an HPAI, ASF or PRRS event, on-site destruction capacity is the difference between managing the problem and waiting on a contractor or state response. Source: USDA APHIS

When evaluating deadstock disposal options for your swine or poultry operation, the comparison looks very different once you put all three methods on the same sheet of paper. Here's how livestock incineration, composting, and rendering compare across the factors that matter most to commercial producers.
| Factor | Incineration | Composting | Rendering Pickup |
|---|---|---|---|
| Infrastructure cost | ✓Concrete pad only | ✗$100,000+ roofed concrete structure with weight-bearing pad | None — but per-pickup fees accumulate |
| Time to dispose | ✓Hours | ✗60–90 days minimum | Depends on pickup scheduling — often 24–72 hrs |
| Pathogen elimination | ✓Complete — 850°C secondary chamber | ✗Unreliable for HPAI, ASF at scale | Eliminated at rendering facility — not on-site |
| Biosecurity perimeter | ✓Carcasses stay on-site — no truck entries | ✓On-site | ✗Truck entry required — biosecurity event every pickup |
| Timing flexibility | ✓Any time — re-entry risk eliminated | ✗End of day only — no re-entry after handling carcasses | ✗Dependent on truck schedule |
| Disease event response | ✓Preferred / required for HPAI, ASF | ✗Inadequate for fast-moving outbreaks | ✗Truck access during active outbreak is high-risk |
| Equipment required | ✓Small skid steer or loader tractor | ✗High-capacity loader tractor — daily use in decomposing material | Loading equipment to staging area |
| Odor / wildlife risk | ✓Water vapor only — no odor, no smoke | ✗Odor during active decomposition attracts wildlife | ✗Staging area exposure until pickup |
| Ongoing operating costs | Fuel per burn cycle — logged by the control panel | Carbon materials, equipment maintenance, labor | Per-pickup fees, fuel to staging |
| Regulatory documentation | ✓State construction permit — 60–90 days, BioSec supports application | Varies by state | Rendering facility handles compliance |

Why Incineration Wins on Biosecurity
Livestock incineration is the only deadstock disposal method that eliminates pathogens on-site, within hours, without any off-property movement. No truck entries. No rendering facility contacts. No exposure pathways outside your perimeter. For operations managing HPAI, ASF, PRRSv, or PEDv risk — this is the difference between a closed loop and an open one.
The $100K Composting Line Item
A properly built composting facility — roofed, multi-bay, concrete pad, weight-bearing construction — costs around $100,000 before a single carcass goes in. Add a high-capacity loader tractor for daily turning in disease-contaminated material. Then wait 60–90 days for the first cycle to complete. Incineration requires a concrete pad and a unit. To load it, a small skid steer or utility tractor is all you need — that machine stays clean and dry. It’s not working daily in decomposing, disease-contaminated material like the loader tractor for composting. Load, burn, walk away.
Mortality Management During a Disease Event
During HPAI, ASF, or PED outbreaks, your mortality management method isn't a background consideration — it's a front-line biosecurity decision. Composting cannot guarantee full pathogen inactivation within regulatory timeframes for highly pathogenic strains. Rendering requires truck access during an active outbreak. Incineration delivers verifiable, immediate pathogen elimination with zero off-site movement.
Frequently Asked Questions
Common questions from US swine and poultry producers evaluating livestock incineration, and mortality management options.
Most comparisons focus on the wrong variable — upfront equipment cost. The full picture looks different when you put both options on the same sheet of paper.
Composting infrastructure costs: A properly built composting facility means a roofed, multi-bay concrete structure — 4 to 6 bays at 8–10 feet with a weight-bearing pad built for daily heavy equipment traffic. That's around $100,000 or more before a single carcass goes in. Add a high-capacity loader tractor capable of turning compost and moving material between bins daily in decomposing, disease-contaminated material. Then factor in carbon sourcing, moisture management, and a 60–90 day minimum cycle before material is safe to handle.
Incineration infrastructure: A concrete pad. Load, burn, done. Pathogens are eliminated within hours — not months.
The timing difference nobody talks about: Composting is strictly an end-of-day task. Employees who handle carcasses can't re-enter production areas, so removal happens once at shift's end. With incineration, carcass removal can happen at any point during the day — re-entry risk is effectively eliminated and loading equipment stays clean.
During a disease event — HPAI, ASF, PED — composting cannot guarantee full pathogen inactivation within the timeframe you need it. Incineration can. No $100,000 structure. No carbon deliveries. No outside trucks on your property.
Livestock incineration — also called on-farm animal cremation or deadstock disposal — is the process of thermally reducing animal carcasses to ash using a controlled dual-chamber combustion system. It is the only mortality management method that delivers immediate, on-site pathogen elimination without requiring truck access, rendering pickups, or off-property movement.
In a properly engineered dual-chamber unit, carcasses are loaded into the primary chamber and combusted. Gases from the primary chamber pass into a separate, dedicated secondary afterburner chamber maintained at a minimum of 850°C (1,562°F) with sufficient volume to give combustion gases the dwell time required to fully combust. What exits the stack is water vapor — no visible smoke, no soot, no odor.
Smoke and odor coming off an incinerator isn't an incineration problem — it's a design problem.
Older barrel-style units and single-chamber machines are still being sold. Some have nothing on the stack at all. Others bolt on a small afterburner at the base of the stack as an add-on — but that approach has a fundamental flaw: retention time.
For secondary combustion to do its job, gases from the main chamber need to remain in a high-temperature environment long enough to fully combust. A small inline afterburner at the stack doesn't provide that. Gases pass through too quickly, exit partially burned, and the result is visible smoke, soot deposits, and odor.
A properly engineered secondary chamber is a separate, dedicated burn zone — not an attachment. A properly engineered unit runs the secondary chamber at 850°C with sufficient volume to give combustion gases the dwell time needed to finish the process completely. For producers near residential neighbors or in areas with setback restrictions, there is no margin for a unit that smokes intermittently. Operations managing mortality year-round can't afford the wildlife attraction that comes with incompletely processed gases.
From a biosecurity standpoint, incineration keeps your perimeter intact. Carcasses never leave the property. No truck entries, no rendering facility contacts, no off-site exposure pathways.
Rendering requires scheduling a pickup — and every truck that enters your site is a biosecurity event. During a disease event or heightened risk period, that entry point matters. Incineration eliminates it entirely. Pathogens are destroyed on-site within hours of discovery, with full documentation of disposal.
For declared disease events including Highly Pathogenic Avian Influenza (HPAI) and African Swine Fever (ASF), incineration is the preferred or required disposal method because it achieves immediate, verifiable pathogen elimination with no off-site movement.
Composting does not reliably reach the temperatures required to inactivate highly pathogenic strains throughout the entire mass within regulatory timeframes. The 60–90 day composting cycle is also incompatible with the fast response window that disease events demand. Incineration also keeps your biosecurity perimeter intact — no carcasses leave the property, no rendering trucks enter the site during an active outbreak.
Yes. Agricultural incinerators are regulated as minor stationary sources and require a state construction permit before installation. The permitting process involves an application with your state environmental agency, including equipment specifications and a potential-to-emit (PTE) calculation for CO based on EPA AP-42 emission factors.
Most states process agricultural incinerator permits within 60–90 days. BioSec Agriculture provides completed PTE worksheets and equipment specs to support your application, with specific permitting guidance for IA, IL, MN, and NE. Contact us for other states.
