Preliminary techno-economic analysis of biodiesel production over solid- biochar

초록

This study suggests the economic potential of biochar-based biodiesel production by conducting the techno-economic analysis. The itemized cost estimation was performed by categorizing biochar production facility and biodiesel conversion plants for 30,000 ton y(-1) of biodiesel production capacity. The result of sensitivity analysis shows the methanol and waste cooking oil (WCO) costs are significantly sensitive to determine a unit biodiesel production cost. When the biodiesel selling price was 1.70 $kg(-1),thediscountedpaybackperiodwasvariedfrom1.91(notdiscounted)to2.06years(10$ kg(-1) when the discount rate was 10%. It means that this technology is to be feasible because of commercial diesel price (0.97 to 1.88 $ kg(-1)). The consideration of tax exemption and subsidy for biodiesel can be good option to supply WCO based energy production.
