Overview

Randomized trial investigates biochar's enhancement of anaerobic digestion performance, suggesting improved waste management strategies.

Key Points

  • This study aims to explore how different biochar properties affect the efficiency of anaerobic digestion.
  • Produced four biochars from spent coffee grounds and tomato plant residues at varying pyrolysis temperatures.
  • Characterized biochar properties using physicochemical assessments including BET analysis and point of zero charge.
  • Evaluated anaerobic digestion performance through biogas production metrics in batch digesters.
  • TP-biochar significantly outperformed SCG-biochar in enhancing methane production and biogas quality.
  • Biochar produced at 500 °C maximized methane output, while material at 900 °C improved the CH4/CO2 ratio, indicating better purification.
  • These results demonstrate that biochar properties directly influence anaerobic digestion stability and efficiency.
