2nd International Conference on
Potential of dry fermentation using novel reactors

University of Borås, Sweden
Dry fermentation for biogas production is gaining significant interest due to its economic feasibility and easy handling of
digestate. In industries, biogas reactors processing wastes with high water content are most common but the use of solid
wastes such as agricultural, municipal and crop residues is becoming more attractive. Processing of these kinds of wastes for
biogas production has been very challenging for industries and developing countries due to problems with feeding, mixing,
and appropriate technology for operation. Hence, there is a need for reactors that are simple to operate, robust in nature and
cost effective. Innovative plug flow and textile bioreactors were developed to solve these problems. The plug flow reactor has
sealed buffer system at the inlet part of the reactor and an impeller between the inlet and outlet for better performance of the
process. This reactor was developed for continuous dry digestion processes and its efficiency was investigated using manure
bedded with straw at 22 % total solid content. The textile bioreactor was made of advanced textiles and coated polymers which
make the bioreactor durable, easily transportable and highly resistant to UV light and high temperature. The efficiency of the
textile reactor was also investigated for batch digestion of manure bedded with straw at 22, 27 and 30 % solid content. The plug
flow reactor worked at increasing organic loading rates of 2.8, 4.2 and 6 gVS/L/d and retention times of 60, 40 and 28 days,
respectively. Organic loading rates up to 4.2 gVS/L/d gave a better process stability, with methane yields up to 0.163 LCH4/
gVSadded/d which is 56 % of the theoretical yield. The textile bioreactor was quite simple to operate. Methane yield after
acclimatization increased from 183 to 290 Nml CH4/gVS.
