[Digestion] pathogens which might create a health hazard

[Johan Carels]

Dear Johan,

Regarding  “pathogens which might create a health hazard. There are reports
on pathogens for man, animal, and plant, which might survive the biogas
process. As  the input material of any biogas plant which is not operated on
a farm level may contain many different types of pathogens you may
accumulate these germs even if they are in a low number in the digestate.”

 

Suggest to pasturise  ( heating at 70°C during 60 minutes)  all the
digestate since you hav e this heat available from the cogenerater [cooling
water, turbocooling, exhaust gase-heat]. This will kill all pathogens.
