 Development status and life cycle inventory analysis of biofuels in TaiwanChiung-Lung Su and Yuh-Ming Lee Energy Policy, 2009, vol. 37, issue 2, 754-758 Abstract: This research conducted the life cycle inventory analyses of biofuels in Taiwan. The biofuels considered include bioethanol production from sugarcane as well as biodiesel production from soybean and rapeseed. Energy inputs and pollutant emission (including carbon dioxide) are the input/output items analyzed. Results obtained from the inventory analyses can be summarized as follows. Bioethanol production from per hectare sugarcane cropland is 5160Â L (liters), meanwhile, 476 and 1012Â L biodiesel can be produced from 1Â ha of soybean and rapeseed, respectively. The energy input to produce a liter ethanol, a liter biodiesel produced from soybean and rapeseed are 1256, 9602 and 5191Â kcal, respectively. Those energy inputs are still less than the energy content of ethanol or biodiesel. It can be concluded that there is a positive energy benefit in producing biofuels based on a comparison with the previous work. In addition, through their life cycle, 1478.4Â kg CO2 emission is generated from one hectare of soybean land and 2954.1Â kg is generated from rapeseed land. Life cycle carbon dioxide emissions released from burning ethanol is 0.08Â kg/LOE in contrast to 2.6Â kg/LOE released from burning fossil gasoline.
