Abstract
Biojet fuel is a low carbon alternative to fossil jet fuel. There is limited literature on life cycle environmental performance of biojet fuel from 2nd generation biomass feedstocks. This research (i) assesses biojet fuel potential from rice, wheat, jute and potato residues in Bangladesh and (ii) conducts farm to factory gate attributional Life Cycle Assessment of biojet fuel. Bangladesh can produce 1074 to 2548 million liters of biojet fuel annually, under different scenarios, with a more realistic potential of 1810 million liters annually. This is 4.5 times higher than the current jet fuel demand of the country. The carbon, energy and landuse footprints of biojet fuel are lower than fossil jet fuel, however, the water footprint is higher. The Energy Return on Investment (EROI) ranges from 1.60 to 1.78. The outcomes of this research will contribute to UN SDGs 7 & 13 and biojet fuel development in Bangladesh. • Agro-residue biomass and biojet fuel potential is assessed for Bangladesh. • Bangladesh can produce 44.87 million tonne agro-residue biomass annually. • Biojet fuel potential is 1810 million liter, 4.5 times higher than current jet fuel demand. • Environmental impact of biojet fuel: jute stalk < rice straw < wheat straw < potato leaves.
