ABSTRACT

Cymbopogon citratus has been identified as a good substrate for the production of high quality biogas but its utilization for medical applications due to its citral content makes the usage very competitive. Although the organic content of the residue remains intact after the extraction of the citral content, he potentials of producing high quality biogas from the supposed waste has not been explored. High quality biogas was produced from the residue of Cymbopogon citratus via anaerobic digestion process for a retention period of 30 days at an average ambient temperature of 34.7±3 oC. A total of 0.123 m3 with estimated average methane content of 70.62% was produced. This study demonstrated that high quality biogas with respect to the methane content could be produced from residues of plants such as Cymbopogon citratus.
