The maximum
methane yield from OPF and OPT was also achieved at 16%
TS and C:N ratio of 30:1 with 280.29 m3 CH4 ton1 VS and
324.91 m3 CH4 ton1 VS, respectively. The methane yield from oil
palm biomass by SS-AD at optimum condition was higher than
other feedstocks from previous report (Table 2). Methane yield
