Bestimmung des Biogasertrags aus Co-Substraten im diskontinuierlichen Durchflussverfahren

Gas yields are usually derived from batch experiments. To approximate full-scale conditions, fermentation tests were carried out in semi-continuously fed digesters. The biogas yields obtained from forage maize and from grass silage were 617 LN (kg oDM)-1 and 493 LN (kg oDM)-1 with a methane content of 53.6% and 54.0 % respectively.
