The principle: no carcass crosses a clean zone
Every modern biosecurity plan starts with zoning. Live animals, feed and clean staff move within the clean zone. Carcasses, manure, dirty PPE and the incinerator live in the dirty zone. The two never cross paths without a hard hygiene break.
Vehicle and visitor control
Off-site rendering collections force a vehicle from outside the holding to enter the boundary, take material from a collection point, and leave. Each collection is a re-introduction risk for AI, ASF, salmonella and IBD.
On-site incineration eliminates that risk entirely — material is destroyed before it ever needs to leave the holding.
PPE and operator hygiene
Operators handling carcasses wear dedicated coveralls, boots and nitrile gloves. PPE stays in the dirty zone. Hands and boots are washed at a hygiene station between dirty-zone work and any other duties.
Ash handling
AIS Cyclone ash is sterile and inert after a complete cycle, but should still be removed using a sealed bucket and either deep-buried (>1 m) on the holding or removed by a licensed waste contractor. Never spread ash on grazing land.
Frequently asked questions
Is incinerator ash safe to handle?+
After a full 850 °C cycle the ash is sterile. Standard PPE (gloves, dust mask) is sufficient when removing it.
Can ash be land-spread?+
Not on grazing land. It can be deep-buried or sent to a licensed waste route per local rules.
