A Comparison of Life Cycle Assessment on Oil Palm (Elaeis guineensis Jacq.) and Physic Nut (Jatropha curcas Linn.) as Feedstock for Biodiesel Production in Indonesia

The objective of this study was to perform and compare LCA of biodiesel production from crude palm oil and crude Jatropha curcas oil. The system boundary for LCA study from cradle to gate. The produced palm oil biodiesel has higher GWP value than Jatropha curcas biodiesel. Utilization of agrochemical, in form of fertilizer and plant protection, generate significant contribution to environmental impact of biodiesel production i.e. 50.46% and 33.51% for palm oil and Jatropha curcas oil, respectively. GWP emission up to five years of plantation is 1 695.36 kg-CO2eq./t-BDF and 740.90 kg-CO2eq./t-BDF for palm oil and Jatropha curcas, respectively. After production stabilised, CO2 emission of diesel fuel decreases up to 37.83% and 63.61% for BDF-CPO and BDF-CJCO, respectively.
