COMPARISON OF THE UTILIZATION OF OIL PALM WASTE FOR BIOETHANOL PRODUCTION

Abstract

To keep up with the demand for a more sustainable and reliable fuel source, Oil Palm waste from crude palm oil production could be used to produce bioethanol as an alternative fuel source. Bioethanol production from Oil Palm solid waste can be made from its juice or lignocellulosic material. The objective of this study is to find the best feed for bioethanol production. The methodology of this research is through the literature methodology by reviewing previous studies about the subject. The result shows that OPF was the most reliable feed for juice methodology and EFB for lignocellulosic methodology. Lignocellulosic methodology was chosen overall to produce bioethanol due to the sheer difference in yield of ethanol compared to juice methodology. The yield of ethanol for OPFS, OPTS, EFBC, OPFC and OPTC are 19.02 g ethanol/Kg OPF, 30.87 g ethanol/Kg OPT, 171.70 g ethanol/Kg EFB, 71.50 ethanol/Kg OPF and 101.82 g ethanol/Kg OPT respectively. Parameters that effect bioethanol production through lignocellulosic methodology are pre-treatment, fermentation method, inoculum, hydrolysis method, pH, temperature, fermentation time and agitation rate. Additional results find that SSF should be used as fermentation method of lignocellulosic EFB, xylitol as by-product of bioethanol production can be used as additional revenue and upscaling a bioethanol plant was achieved through the expansion, replication, and collaboration the process.
