3. However, in this analysis, the overall thermal efficiency is assumed to be only 25 % for power output. Thus, 1 ton of EFB
with 65 % moisture should deliver 6,028,000 x 0.25 kJ = 1,507,000 kJ of energy.
1,507,000 kJ = 1,507,000 / 3,600 kWh = 418.6 kWh
4. According to MPOB, 0.65 m3 POME is generated from every processed ton of fresh fruit bunch

In the following Figure, the composition of biogas from POME has been determined as 62.5 % methane, 37 % Carbon dioxide and 1,500-3,000 vppm hydrogen sulphide. The calorific value for the generated biogas is 22,000 kJ/m3. The heating value (average caloric value) of methane was 36.3 MJ m3 at standard conditions (Matteson and Jenkins, 2005). This corresponds to 10.888 kWh of energy per 1 m3 of methane.
