The depletion of fossil fuels and natural raw materials has encouraged the search for new resource materials for the production of bio-based materials (Alekhina et al., 2014). Oil palm biomass (OPB) is classified as lignocellulosic residues comprised mainly of cellulose, hemicellulose, and lignin in their cell walls (Raveendran et al., 1995). This lignocellulosic material can be converted into valuable feedstock for the production of biosugar, biocompost, biochemical and bioethanol. Due to the lignocellulosic nature of OPB, countless research and development activities were undertaken by various agencies in order to improve the transformation of OPB into more valuable substrate for producing a variety of chemicals that will have huge potential in food, chemical and pharmaceutical industries. The chemical constituents in OPB varied considerably due to their diverse origins and types (Chew and Bhatia, 2008). The chemical composition of different OPB is shown in Table 1.
