Special mobile equipment to turn and move the composting materials is essential for satisfactory decomposition of carcasses. Unlike other disposal methods the bulky composted material must still be disposed of in an acceptable manner. Composted carcasses should not be spread on pastureland because of the potential for botulism poisoning in grazing animals. Instead, spread the material on hay fields or cropland where animals have no opportunity for direct contact with the compost. However, expensive smokeless incinerators must be used and properly operated and maintained to prevent smoke and odor complaints.
Nuisance complaints generated by poor maintenance and operational efforts are common.
Incinerators wear out and must be replaced periodically. To, fuel for incinerating carcasses is a significant expense. Costs of operation and discipline required to prevent complaints have reduced the popularity of incineration in recent years. Incinerators must be operated properly to maximize equipment life and minimize emissions problems. Load according to manufacturer recommendations to minimize problems.
