Fermented residues from biogas plants contain volatile substances, which without due care can contaminate the ground water with i.e. Nitrate. Through addition of biochar in the fermented residue of biogas plants nutrients will adhere to the porous surface of biochar.



  • Biochar in fermented residues of biogas plants reduces the loss of nutrients
  • A potential odour nuisances through the fermented residues reduces tremendously and increases acceptance of biogas plants in public
  • Through the addition of biochar in the fermented residue the value of the residue increases as nutrients stick to the biochar and therefore stay with the residue and are not washed into the ground water.
