Abstract
The potential of mesophilic anaerobic batch digestion for the treatment of Spartina alterniflora, an invasive species widely distributed along Chinese coastlines, through co-digestion with readily biodegradable organics has been assessed. The accumulative biogas yield from S. alterniflora alone was 251 ml/g Total Solid (TS) (at 35°C), at TS of 6%, co-digestion with 80% of S. alterniflora and 20% of potato representing 6% of TS, gave a biogas yield of 383 ml/g TS (at 35°C). This is an increase of 52.5% compared with that obtained from digestion of pure S. alterniflora. In conclusion, using readily biodegradable potato as co-substrate of S. alterniflora can increase its anaerobic digestibility and biogas yield.
