Oil palm empty fruit bunches (OPEFB), a waste lignocellulosic material, which is the main byproduct
of vegetable oil production industries in Indonesia and Malaysia, was utilized as a source for biogas
production. Pretreatments using NaOH as well as phosphoric acid were investigated to improve the
biogas production. Clear positive effects of the pretreatments on the yield of methane were observed.
The best improvement was achieved when 8% NaOH for 60 min was used for the pretreatment, which
resulted in 100% improvement in the yield of methane production. In addition, treatment with phosphoric
acid resulted in 40% improvement in the methane yield compared with that of the untreated material.
The results showed that the carbohydrate content of OPEFB could be efficiently converted to methane
under the anaerobic digestion process. 97% of the theoretical value of methane production was achieved
after the pretreatment with NaOH for 60 min. Moreover, the initial rate of methane production was also
increased by more than 85% after the treatment with NaOH compared with that of the untreated OPEFB.
