Biosafety involves prevention of exposure to pathogen to ensure diseases cannot spread to animals or humans, via the biodigester. Nature Energy is very precautious to the biosafety of the agricultural companies it will be doing business with. In addition to the biosafety practices already in use in Denmark (such as washing trucks after each trip to a farm), a biosafety protocol is currently being put in place, with the help of a veterinarian specializing in this field.
