Biomass pasteurization for biogas and biomethane plants the technical advantages of BioBANG cavitation

Why is the pasteurization of biomasses becoming more and more a required practice for biogas and biomethane plants?

In many countries the regulations for specific biomasses (eg: animals and vegetables organic waste, industrial and municipal slurries, etc …) require that a pasteurization treatment be carried out before they are loaded into the digesters. A particular case is given for example by France where the regulations on the pasteurization of agricultural sewage destined for anaerobic digestion are becoming increasingly stringent.
