Biochar

HTC-Reactor
Versuchsanlage zur hydrothermalen Karbonisierung

The production of biochar from digestate biogas production is the focus of the research group APECS (Anaerobic Pathways to Renewable Energies and Carbon Sinks).
APECS developes a powerful hybrid method in which methods of CO2 neutral energy production and environmentally sound recovery incurred residues are combined into biochar. The biochar as a soil conditioner to increase the sorption capacity of the soil for nutrients and water, remove CO2 from the atmosphere and establish long-term according to a new carbon sink in agriculture.

Current research

• 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
