Environmental life cycle assessment of bioethanol production from wheat straw

摘要: Abstract Ethanol produced from lignocelluloses is expected to make a major contribution on transportation fuel markets. In this paper, life cycle assessment was carried out assess the environmental burdens of ethanol production wheat straw and its use as blend fuels. Two based E15 (a mixture 15% 85% petrol by volume) E85 (85% were assessed results compared those conventional (PT) in 1 km driven an equivalent car. The performance studied using ReCiPe methodology includes global warming, ozone depletion, photochemical oxidant formation, acidification, ecotoxicity, eutrophication, water depletion fossil depletion. show that, petrol, greenhouse gas emissions are lower for blends, with 73% reduction E85-fuelled car 13% E15. A modest savings 40% also found when Similar observed findings highlight number issues such ecotoxicity which areas does not offer any advantages petrol. further analysis at well gate level helps identify key cycle. indicate where effort needs be placed improve technology process design can help lowering impacts whole
