CONCLUSIONS: Composting did not completely kill the AD virus even at the hottest spots of the compost bins. A composting temperature above 65oC partially inactivated the AD virus. Since temperatures above 65oC were not reached in all sections of the compost bins, not all the AD viruses will have been exposed to a high enough temperature. This is the first experiment to investigate the inactivation of the AD virus by composting. Further work is needed to achieve enhanced and sustained thermal activity in all layers of a bin during composting and to determine if the AD virus can be killed.
