Overview

Randomized trial demonstrates increased biogas production using biochar in anaerobic digestion, indicating efficiency gains.

Key Points

  • The aim is to assess the impact of sludgechar on biogas production and process stability during anaerobic digestion of sewage sludge.
  • Continuous laboratory bioreactors operated at mesophilic conditions (40 °C)
  • Dosing of sludgechar at 0.4–1.3 g/(L·d), corresponding to 12–28% of added COD
  • Gradual increase of loading rate from 3.2 to 4.5 g/(L·d)
  • Biogas production increased by 6.9–33% compared to the control.
  • CH4 concentration averaged 62.8%, remaining stable.
  • COD removal stayed high in sludgechar bioreactor despite increased loading, unlike the control bioreactor.
