Anaerobic digestion (AD) can significantly reduce pathogens in pig carcase material (PCM), according to new research at Harper Adams University.
The research also showed that bio-reduction through AD could provide a solution to on-farm storage or disposal of pig carcase material which could reduce the costs of fallen stock collection and reduce vehicles driving between farms.
The first stage of the research established that the AD process could significantly reduce the number of particularly resilient pathogens in PCM and that it can generate considerable quantities of biogas.
The second stage, funded jointly by Defra and BPEX, is aimed at reducing fossil fuels by helping towards AD being used as a self-sustaining on-farm system for storage or disposal of PCM.
Before being developed commercially, AD must provide a positive outcome which can then be approved by the EU.
