Anaerobic digestions of pretreated OPMF and CM seeded with
POME are feasible and stable processes. The anaerobic codigestion
boosted biogas production and achieved stable performances of
anaerobic digestions. The biodegradation of the substrate shows
that the mixtures in sample D perform better since it has the
highest percentage lignin removal of 37.3% compared to 35.2% in
sample B and 26.6% in sample C. The pretreated OPMF co-digested
with CM gave a higher and better digester performance and higher
biogas production. The methane generation for the digesters
R1eR4 was found to be 63, 46, 35 and 31% while in total biogas
