摘要: Abstract This study evaluated the life cycle of bioethanol produced by enzymatic hydrolysis rice straw. Net energy consumption, CO 2 emission and production costs were estimated to determine whether environmentally preferable economically viable can be from straws. Two varieties straw ( Koshihikari Leafstar ), three scenarios (F-E-RH: Fuel-Electricity-Residues used for Heat; F-E-RE: generate Electricity; F-RE: Fuel-Residues Electricity) types primary (heavy oil; LNG: liquefied natural gas; agri-residues) considered. The net 10.0–17.6 MJ/L, −0.5 1.6 kg/L 84.9–144.3 ¥/L (1 US$ ≈ 100 ¥), respectively, depending on feedstock this study. A shift in or type oil LNG not only reduces emissions straw, but may also reduce fluctuation cost over time risk investment, which would encourage more investment sector.
