Hog carcass disposal methods should be carefully considered in the context of how each one would work within a specific situation. Then, the cost to implement each feasible method should be estimated, accor-ding to the University of Nebraska Extension researchers. The result should be a method that is environ-mentally sound and cost effective for your operation.

As part of your evaluation, consider the logistic factors first. Here are some of the considerations that you need to evaluate.

Incineration

  • Make sure smoke and odors will not be a nuisance to neighbors.
  • Carcasses need to be smaller than 550 pounds.
  • Required permits will be needed– annual reporting is required.

Burial

  • Do you have access to a backhoe or other earth-moving equipment?
  • Is labor available for daily trenching and covering?
  • Is land available year round for carcass burial?
  • Ensure the burial pit is at least 100 feet away from production facilities.
  • Burial sites must consist of deep, fine-textured soils.
  • Does underlying geology pose little risk for groundwater contamination?
  • Make sure trench-bracing equip-ment is available.

Composting

  • Is an ample carbon source available?
  • If not using sawdust, you will need a bale processor or other means to chop wheat straw, brome hay and other similar material.
  • Is there enough available labor to process carcasses and turn compost?
  • Is there  a location available for the composter?
  • Composter site is at least 100 feet away from production facilities.
  • The composter does not pose a risk to surface water.
  • A manure spreader is available to land apply compost.
  • A bucket loader is available for loading and turning compost.
  • Land is available for spreading finished compost.

Rendering

  • A pickup service is available.
  • Carcasses can be removed without compromising farm biosecurity.
  • The carcass-storage area is at least 100 feet from production facilities.
  • Carcass-storage area is well screened from public view.
