Hythane production from anaerobic digestion of MEG-based substrate was examined.
- class="label">•
Optimum H2 and CH4 production depended on inoculum-to-substrate ratio (ISR) and N/P.
- class="label">•
CH4 yield peaked (152 mL/gCODinitial) at ISR of 5.29 gVSS/gCOD and N/P ratio of 5.5.
- class="label">•
H2 yield at optimum ISR and N/P, further peaked at pH 5.0 using pre-treated sludge.

Regarding energy recovery, substantial economic/environmental profits were achieved.
