In Sarawak, East Malaysia, agro-residues from sago starch processing industries are abundant and readily available. It has been estimated approximately 7 tonnes of sago pith waste was produced daily from a single sago starch processing mill. Currently these residues were washed off into nearby streams together with wastewater and deposited in the factory’s compound, which can lead to serious environmental problems. Bioconversion of the agro‐residue offers the possibility of creating marketable value‐added products. Utilization of sago residue not only reduce the polluting effects from the sago processing industries, but will also provide an economic solution for waste management system at sago processing mills. This study emphasized on utilizing the trapped starch in sago hampas as a source for glucose production via enzymatic hydrolysis which will later use as substrate for bioethanol fermentation. Initially, three different loading amount (w/v: 5%, 7% and 9%) of sago hampas were examined for glucose production using commercial enzyme. As a result, almost all of trapped starch in 5% and 7% of sago hampas were converted into glucose after 60 min of enzymatic hydrolysis.
However for 9% sago hampas, some starch still left behind even though the same procedure of hydrolysis was carried out. Alternative method which is recycles the solution of hydrolyzed sago hampas (HSH) was introduced. Greater improvement of glucose concentration (175.85 g/L) was achieved successfully. Ethanol concentration of 40.3 g/L was obtained from 84.7 g/L of initial glucose by batch fermentation using commercial baker yeast. This study shows the ability of waste starch from sago hampas to be utilized as a feedstock for bioethanol production.
