Techniques for cassava biogas production
Biogas production from cassava requires selection of an appropriate
system from various digester techniques together with proper digester
design. This requires a thorough grasp of the technologies used in
various parts of the world that have proved successful. The various
techniques and advantages and disadvantages of each of them are
explored as follows. The most promising technologies applicable for
cassava biogas production are highlighted where necessary and
combinations of technologies where appropriate are recommended.
However, the final choice of design and technology lies with the
investigator or stakeholder. A summary of the potential pros and cons
of each of the digester configurations is shown in Table 8.
Fermentations for biogas production are performed in anaerobic
digesters. There are different digester-configurations depending
on the process condition selected which may be either:
Batch or continuous.
Two-phase or two-stage.
Dry or wet mode.
Mesophilic or thermophilic.
