Besides the actual depopulation itself, determining how to dispose of carcasses is also a difficult decision.
Equipment, inputs and time are the three primary considerations in terms of disposal, said Marguerite Tan, Director of Environmental Programs for the National Pork Board.
Methods include:
- Incineration
- Deep-pit burial
- Whole composting
- Ground composting
- Shallow burial with carbon (treatments that require carbon)
Many factors come into consideration, including virus inactivation, available real estate, distance to groundwater, soil types, well- and surface-water locations, topography, state regulations and deed restrictions.
