Carbon Dynamics of Anaerobic Residues from Biogas Plants Using Energy Crops

K. Sensel, K. Nielsen, V. Wragge & J. Rühlmann
The short term C­mineralization of two different biogas residues under anaerobic and aerobic conditions were investigated. The residues derived from one liquid fermentation biogas plant fermenting maize silage and cattle manure and one dry fermentation biogas plant fermenting sole maize. The determination of C­mineralization under anaerobic conditions characterizes the residual biogas potential (RBP). The loss of carbon through biogas formation was measured at two different temperatures. The total amount of residual biogas after 90 d...
