It could be shown, that ultrasound disintegration of biological
waste material chicken manure for biogas production is
technological and economical effective. The biogas yield and
methane content could be increased up to 41% and 2.4percentage points, respectively, whereas high reaction time
and lower ultrasound amplitudes show the best results.
Moreover, the increased biogas yield could be ascribed to
increased bioavailability of biomass substrates and not to a
change in nutrient relation. The effect of disintegration and
the expected biogas yield can be controlled by the specific
surface of the biomass particles and is useful for industrial
applications. Moreover it could be shown, that the energy
used for disintegration is significant lower than the energy
generated by the additional volume of biogas by disintegration
and in the best case 0.69 kWh more energy could be generated
per kg ODM.
