    Baseline study of methane emission from open digesting tanks of palm oil mill effluent treatment
    (Elsevier, 2005) Shahrakbah Yacob; Mohd Ali Hassan; Yoshihito Shirai; Minato Wakisaka; Sunderaj Subash
    Anthropogenic release of greenhouse gases, especially CO2 and CH4 has been recognized as one of the main causes of global warming. Several measures under the Kyoto Protocol 1997 have been drawn up to reduce the greenhouse gases emission. One of the measures is Clean Development Mechanisms (CDM) that was created to enable developed countries to cooperate with developing countries in emission reduction activities. In Malaysia, palm oil industry particularly from palm oil mill effluent (POME) anaerobic treatment has been identified as an important source of CH4. However, there is no study to quantify the actual CH4 emission from the commercial scale wastewater treatment facility. Hence, this paper shall address the CH4 emission from the open digesting tanks in Felda Serting Hilir Palm Oil Mill. CH4 emission pattern was recorded for 52 weeks from 3600 m3 open digesting tanks.

    Reduction of methane released from palm oil mill lagoon in Malaysia and its countermeasures
    (Kluwer Academic Publishers, 2003) Yoshihito Shirai; Minato Wakisaka; Shahrakbah Yacob; Mohd Ali Hassan; Shin’ichi Suzuki
    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.
