Abstract: | Palm oil industry in Malaysia is one of the potential candidates for the CDM project because large amount of methane is emitted
from the lagoons and open digesting tank of the wastewater treatment system. Therefore the first objective of the project
is to investigate the actual GHG emission from the lagoons and open digesting tank in palm oil mills in order to establish
the baseline for CDM project. Results indicated that methane contribution to biogas released from the open digesting tank
and lagoon systems were 35% and 45%, respectively. These values are much lower than the reported value of 65% obtained by
complete anaerobic condition of lab-scale experiments. Based on actual methane release measurement and information gathered
from palm oil mill about wastewater treatment, significant amount of methane emission to the atmosphere can be reduced with
the installation of new closed digesting tank system converted from the open digesting tank such as just by covering it with
applying CDM. It is estimated that a total of RM2.6 million could be obtained from the selling of electricity generated from
biogas generation and Certified Emission Reduction(CER).
