The production of biochar from digestate biogas production is the focus of the research group APECS (Anaerobic Pathways to Renewable Energies and Carbon Sinks).
• Comparison of different methods for carbonization of the digestate (pyrolysis and hydrothermal carbonization)
• Characterization of different biochars regarding stability of carbon compounds and adsorption
• Optimization of biochar properties
• Effects of biochar as a soil additive
• Review of the process in terms of function, performance, cost and environmental impact
