Harper Adams University near Newport, England, have conducted research about how to reduce the number of resilient pathogens in porcine carcass material. The research has shown that sterilising and then disposing the pig carcasses through anaerobic digestion could generate considerable quantities of biogas for heat or electricity. Additionally, disposing of pig carcasses this way can reduce the cost of fallen stock collection and movement of vehicles between farms.
The research is important due to EU legislation which prohibits farmers from burying fallen stock on farm. The legislation came in to place after the BSE (Bovine spongiform encephalopathy, also known as mad cow disease) epidemic in cattle and other livestock diseases.
